Best Mortgage Lenders in the UK (2026)

The UK mortgage market is dominated by a handful of major banks and building societies, but the "best" lender really depends on your situation (first-time buyer, remortgage, buy-to-let, etc.). Here's a breakdown of who's actually used most, and who rates well.

The "Big Six" – Who Most People Actually Use

When searching for a mortgage in the UK, you will likely come across the "Big Six" lenders who dominate the landscape with a combined market share of over 70%. By gross lending share, the ranking is roughly:

• Lloyds Banking Group leads with a 16.8% share (£52.7 billion), followed by NatWest Group at 13.2% (£41.5 billion) and Building Society at 12.1% (£37.8 billion)
• Rounding out the top six: Nationwide, Santander UK, Barclays, and HSBC Bank

Lloyds Banking Group includes Halifax, one of the UK's most recognisable mortgage brands for everyday borrowers.

Highly-Rated Lenders (Which? 2026 Analysis)

Which? analysed the rates and upfront fees of thousands of mortgage deals over a three-month period, in the summer/autumn of 2026 and gave their top "Recommended Provider" badges to:

• Nationwide Building Society – consistently top-rated across satisfaction and value
• Barclays Mortgages – strong all-rounder with high satisfaction scores
• First Direct – rated highly particularly for customer service

Other strong performers in their comparison included Principality, Skipton, Accord Mortgages, and Yorkshire Building Society.

Best Lender by Specific Need

Based on broader market analysis, here's how lenders stack up by use case:

• Best overall / widest product range: The sheer variety of offerings, along with attractive terms, make HSBC one of the best mortgage lenders available in the UK
• Best for first-time buyers: Nationwide is hands down one of the best mortgage lenders in the UK and also the best for first-time buyers, thanks largely to its "Helping Hand" affordability boost scheme
• Best for customer service/digital banking: First Direct — known for excellent telephone and app-based service
• Best for buy-to-let: Halifax
• Best for fixed-rate deals: NatWest
• Best for interest-only: Santander
• Best for remortgaging: Royal Bank of Scotland (NatWest Group)

Innovative/Niche Options Worth Knowing

A few lenders stand out for creative schemes that help specific groups:

• Skipton Building Society – its ‘Track Record’ mortgage for renters helps renters with a strong payment history buy without a traditional deposit
• Yorkshire Building Society – offers an innovative £5k fixed deposit scheme for buyers who can save £5,000 but not a full 5% deposit
• Halifax – its "Family Boost" mortgage lets family savings support a deposit

Speed of Approval (if time matters)

If you need a fast completion, broker data suggests TSB is the fastest on average, followed by Santander and Skipton, though the exact ranking depends on case type, so the fastest lender for a self-employed borrower will not always be the fastest for an employed first-time buyer.

Practical Takeaway

For most people walking into this fresh, the sensible approach is:

1. Start with the big names – Nationwide, Halifax, NatWest, Barclays, Santander, and HSBC cover the vast majority of the market and offer competitive, well-tested products.
2. Use a mortgage broker or comparison site (like L&C, which Which? partners with) rather than going direct to just one lender — rates change daily and the "best" deal shifts constantly.
3. Match the lender to your situation — e.g., Nationwide or Skipton if you're a first-time buyer with a small deposit;

There’s no single “best” UK mortgage lender — the best one is the lender that accepts your case and gives you the lowest total cost for your circumstances. That said, most UK borrowers use a fairly small group of high-street banks and building societies. If you’re in the UK, these are the names you’ll see most often in broker searches and on the high street.

Top UK mortgage brands people actually use

The big high-street names

• Nationwide Building Society – Largest building society. Very strong for first-time buyers, 95% LTV deals, and its “Helping Hand” income-boosting option. Often good service.
• Halifax – One of the biggest lenders. Broad range for first-time buyers, remortgages, and buy-to-let via BM Solutions.
• Lloyds Bank – Same group as Halifax. Competitive, especially if you bank with them. Good first-time buyer range.
• NatWest / Royal Bank of Scotland – Major high-street lender. Good for first-time buyers, remortgages, green mortgages, and buy-to-let.
• Santander UK – Consistently competitive fixed rates. Strong for remortgages and first-time buyers.
• Barclays – Competitive rates, Premier banking, green mortgages, and some offset-style options.
• HSBC UK – Often sharp rates, good for larger loans and Premier customers.
• Virgin Money – Competitive fixes, first-time buyer and buy-to-let options.
• TSB – Smaller high-street presence but still used, especially for remortgages.

Building societies and specialist names

• Coventry Building Society – Regularly competitive, good for offset mortgages and buy-to-let.
• Skipton Building Society – Strong for first-time buyers, shared ownership, and complex income.
• Leeds Building Society – Good for shared ownership, new-build, and offset.
• Yorkshire Building Society / Accord Mortgages – Yorkshire BS is broker-friendly; Accord is broker-only and often competitive.
• The Mortgage Works (Nationwide) – Huge buy-to-let lender.
• BM Solutions (Lloyds Banking Group) – Major buy-to-let lender.
• Paragon, Precise, Kent Reliance, Vida, Pepper Money, Foundation Home Loans – Specialist lenders for self-employed, adverse credit, complex buy-to-let, etc. Usually accessed through a broker.

Products people actually use

• 5-year fixed rate – The most popular choice now. Gives certainty over repayments.
• 2-year fixed rate – Popular if you plan to move, remortgage, or expect rates to fall.
• Tracker mortgages – Follow the Bank of England base rate. Cheaper if rates fall, but repayments can rise.
• Offset mortgages – Let you offset savings against the mortgage balance. Coventry, Yorkshire BS, Accord, and Barclays are common names here.
• Buy-to-let interest-only – Common with TMW, BM Solutions, NatWest, Barclays, Santander, Virgin Money, and Paragon.
• Shared ownership mortgages – Nationwide, Halifax, Leeds, Skipton, Coventry, and Santander are active.
• Green mortgages – Nationwide, Barclays, NatWest, Halifax, and Santander have offered these for energy-efficient homes.

Rough shortlist by situation

• First-time buyer: Nationwide, Halifax, Santander, Barclays, Lloyds, NatWest, HSBC, Skipton, Coventry. Look at 95% LTV 5-year fixes and shared ownership.
• Remortgage: Nationwide, Halifax, Barclays, NatWest, Santander, HSBC, Coventry, Accord. Always check your current lender’s product transfer first.
• Buy-to-let: The Mortgage Works, BM Solutions, NatWest, Barclays, Santander, Virgin Money, Skipton, Paragon.
• Offset: Coventry, Yorkshire Building Society, Accord, Barclays.
• Self-employed / complex income: Skipton, Accord, Precise, Kent Reliance, Vida, Pepper Money, Foundation.
• Large loans / private banking: HSBC Premier, Barclays Premier, NatWest Premier, Coutts, Handelsbanken, Investec.

How to actually find the best deal

1. Use a whole-of-market broker – e.g. L&C, Habito, Mojo, Trussle, or a good local independent. They can access broker-only deals from Accord, Platform, TMW, BM Solutions, Precise, etc.
2. Compare total cost, not just rate – Product fee, valuation fee, legal fees, early repayment charges, and overpayment limits matter.
3. Check flexibility – Can you overpay? Can you port the mortgage if you move? What’s the ERC?
4. Get a Decision in Principle before viewing properties.
5. Start remortgaging about 6 months before your deal ends.

Rates change daily, so I wouldn’t quote specific numbers. The names above are the ones UK borrowers actually use most. If you want a practical shortlist, start with Nationwide, Halifax, NatWest, Santander, Barclays, HSBC, Lloyds, Virgin Money, Coventry, and Skipton, then ask a broker to check exclusives.

General information only, not personal financial advice. Your home may be repossessed if you do not keep up repayments on your mortgage.

In the UK, choosing a mortgage lender is less about finding a single "best" brand and more about finding the lender whose underwriting criteria and rates align with your specific financial situation.

Because of this, roughly 84% of all UK mortgages are arranged through independent, whole-of-market brokers (like L&C, Tembo, or Mojo) rather than by walking straight into a high-street branch. Brokers have access to "broker-only" deals and know which lenders are most likely to accept you.

However, if you are looking at the top brands and products that people actually use, they generally fall into two categories: The High-Street "Big Six" (which handle the vast majority of UK lending) and The Customer Service Champions (mostly building societies, which consistently top consumer satisfaction tables).

---

1. The High-Street "Big Six" (The Giants)

These six lenders dominate the UK market. They have the financial muscle to offer highly competitive interest rates, especially if you have a larger deposit (low Loan-to-Value, or LTV).

• Halifax (part of Lloyds Banking Group):
  • Who it’s for: First-time buyers and those looking for a fast, fuss-free process.
  • Why they are popular: Halifax is the UK's largest mortgage lender and is highly regarded by brokers for its speed, automated processing, and flexible lending criteria. They are notoriously "common-sense" lenders when it comes to assessing complex incomes or self-employed applicants.
  • Key Product: In 2026, parent company Lloyds launched a highly publicised £5,000 deposit mortgage scheme designed to help first-time buyers secure a home with a tiny deposit (allowing up to 99% LTV on certain properties).
• Nationwide Building Society:
  • Who it’s for: Buyers looking to maximise their borrowing power, or those prioritising customer service.
  • Why they are popular: Nationwide is a member-owned building society that regularly wins consumer awards. They are currently a Which? Recommended Provider.
  • Key Product: Their "Helping Hand" mortgage allows first-time buyers to borrow up to 6 times their income (compared to the standard industry limit of 4.5x). In 2026, Nationwide extended this 6x lending option to home movers and remortgagers (subject to earning thresholds of £75,000 for sole applicants or £100,000 for joint applicants). They also offer a popular 0% interest Green Additional Borrowing scheme for energy-efficient home improvements.
• Barclays:
  • Who it’s for: Buyers with family assistance.
  • Why they are popular: Barclays is highly competitive on fixed rates and is a Which? Recommended Provider.
  • Key Product: The Family Springboard Mortgage. This allows you to buy a home with a 0% deposit if a family member puts 10% of the property's purchase price into a linked Barclays savings account for a set period (earning interest while doing so).
• HSBC UK:
  • Who it’s for: High earners, those with clean credit, and buyers with large deposits.
  • Why they are popular: HSBC consistently leads the market on price, regularly offering some of the lowest 2-year and 5-year fixed rates. However, they have stricter underwriting criteria and a more rigid application process than Halifax or Nationwide.
• NatWest:
  • Who it’s for: Standard buyers and existing NatWest current account holders.
  • Why they are popular: NatWest (which is a Which? Recommended Provider) has a highly streamlined digital application process and offers great loyalty deals to existing customers.
• Santander:
  • Who it’s for: Standard buyers, remortgagers, and buyers looking for competitive fixed rates.
  • Why they are popular: They offer highly competitive deals across all LTV brackets and are very active in the remortgage market.

---

2. The Customer Service Champions (Building Societies & Mid-Tier)

If you want a lender that treats you like a human being rather than a computer algorithm, building societies consistently outperform the major high-street banks in consumer surveys.

• Skipton Building Society:
  • Why they are popular: Ranked joint-top in the most recent Which? mortgage satisfaction tables with a 78% customer score. Skipton is praised for its transparency, lack of hidden fees, and excellent customer service.
  • Key Product: Skipton’s innovative "Track Record" mortgage. This is a 100% LTV (no deposit) mortgage specifically for renters. If you can prove you have a strong history of paying rent on time, Skipton will let you borrow up to 100% of the property value, with your monthly mortgage payment capped so it doesn't exceed your average rent.
• Yorkshire Building Society:
  • Why they are popular: Also scored incredibly high (75%) by Which?, receiving a full five stars for customer service and transparency of charges. They offer highly competitive fixed-rate deals and offset mortgages.
• Coventry Building Society:
  • Why they are popular: Coventry is a broker favourite due to its highly efficient administration and clear communication. They consistently offer some of the best offset and buy-to-let mortgages on the market.
• First Direct:
  • Why they are popular: A division of HSBC, First Direct is famous for topping customer service tables across the entire banking industry. They are a Which? Recommended Provider and are particularly popular for their highly flexible offset mortgage products.

---

Which lender should you choose?

• If you are a renter with no deposit: Look at Skipton's Track Record mortgage.
• If you have a tiny deposit (£5,000): Look at Lloyds/Halifax's first-time buyer scheme.
• If you need to borrow the absolute maximum amount possible: Look at Nationwide’s Helping Hand (up to 6x income).
• If you have a massive deposit (e.g., 40% / 60% LTV): Check HSBC or Barclays, as they tend to fight for this business with the absolute lowest interest rates.
• If you are self-employed or have complex income: Go through a broker, but expect them to steer you toward Halifax, Kensington, or Accord Mortgages (Yorkshire BS's broker-only arm), which use manual underwriting rather than automated computer decisions.

The Golden Rule of UK Mortgages

Do not simply walk into your own bank's branch and accept their first offer. Before committing, use a free online comparison tool (like MoneySavingExpert's Best Buys or MoneySuperMarket) to benchmark rates. Then, speak to a fee-free, whole-of-market mortgage broker. They will handle the heavy lifting, navigate the different lenders' criteria, and ensure you actually get approved.

The best mortgage lenders in the United Kingdom based on customer satisfaction and overall usage are Nationwide Building Society, Halifax, NatWest, Barclays, and Santander. Together with HSBC, these institutions make up the "Big Six" lenders that dominate the UK mortgage landscape, controlling the vast majority of the country's housing market share.

Choosing the right brand depends on whether you value market-wide volume, high customer service scores, or specialized borrowing schemes.

The Most Popular Lenders by Volume (The "Big Six")

If you are looking for the brands that the majority of UK homeowners actually use, these are the market leaders by outstanding lending volume and widespread high-street presence:

Halifax (Lloyds Banking Group): This is consistently the single largest mortgage brand in the UK. It is highly popular due to its reputation for processing applications quickly and offering competitive, mainstream rates. Nationwide Building Society: The UK's second-largest mortgage provider and its largest building society. It frequently tops consumer recommendations for its balance of competitive pricing and superior customer service. NatWest Group: A major high-street presence favored by buyers who value a straightforward digital application process and flexible terms, such as generous overpayment allowances. Santander UK: Known for strong across-the-board performance, offering competitive fixed and tracker rates for mainstream residential moves. Barclays Mortgage: A highly trusted traditional lender that consistently receives strong marks for its online account accessibility and app functionality. HSBC Bank: A top choice for borrowers seeking some of the lowest raw interest rates on the market, especially for those with larger deposits.

Top Lenders for Customer Satisfaction

If customer service, clear communication, and transparent fee structures are your priority, independent consumer surveys from platforms like Which? Mortgage Lender Reviews highlight the top-rated providers:

Nationwide Building Society: Awarded "Recommended Provider" status with excellent scores for interest rate clarity and overall customer communication. Principality Building Society: Tied at the top of customer satisfaction tables, particularly celebrated for its high-quality customer care and regional support. First Direct: Celebrated for its stellar telephone-based customer support and strong digital banking interface.

Best Brands for Specific Buyer Profiles

Many buyers choose a lender based on specific product innovations rather than brand size. Leading options include:

For First-Time Buyers with Small Deposits: Nationwide stands out for its Helping Hand scheme, which allows lower-income earners to borrow up to 20% more than typical affordability limits. Halifax is widely used for its Family Boost product, which lets parents secure a 0% deposit mortgage by leveraging their savings. For Renters: Skipton Building Society offers a highly popular Track Record mortgage, allowing renters with a strong history of monthly rental payments to secure a 100% mortgage without a cash deposit. For Non-Standard Circumstances: If you are self-employed or have a spotty credit history, mainstream high-street banks may reject you. Borrowers in this bracket often look to specialist brands like Kensington Mortgages, Precise Mortgages, or Pepper Money, which assess risk on a case-by-case basis.

Note: Because mortgage rates shift daily based on the broader macroeconomic environment, most consumers navigate these brands using a fee-free broker like L&C Mortgages or Habito to scan the entire market for the cheapest specific product before applying.

To help narrow this down for your exact situation, let me know:I can pinpoint which specific lender or product fits your profile best. Are you a first-time buyer, moving home, or remortgaging? Approximately what percentage of a deposit do you have saved? Do you have standard employment income, or are you self-employed?

The top-rated and most widely used mortgage lenders in the United Kingdom combine the "Big Six" major market volume leaders with the highest-scoring providers for customer service and satisfaction according to Which? Mortgage Rankings.

Nationwide Building Society: Ranked as a top recommended provider with an 81% customer score, strong digital app access, and competitive fixed-rate deals (such as fixed rates dipping below 4.5% for movers and buyers).

Principality Building Society: Tied for the highest customer satisfaction score at 81%, known for a strong member-focused approach.

Barclays: A major high-street lender and recommended provider with a 74% customer score, offering broad product availability and reliable online management.

First Direct: A digital-first subsidiary of HSBC that scores high on customer service (74% score) with a 5-star rating for app and online access.

NatWest: A leading volume lender and recommended provider (74% score) known for streamlined digital tools and helpful rate-change communication.

Santander: One of the Big Six national lenders with a solid 74% customer score and widespread product choice for home movers and first-time buyers.

Lloyds Bank & Halifax: Part of the Lloyds Banking Group—consistently the largest residential mortgage provider by volume in the UK.

Key Mortgage Types People Use in the UK

2-Year Fixed-Rate Mortgages: Best for borrowers who want short-term certainty but expect or want the flexibility to refinance or switch deals relatively soon.

5-Year Fixed-Rate Mortgages: Currently the most popular choice for long-term stability and protection against fluctuating Bank of England base rates.

First-Time Buyer Products: Lenders like Nationwide and Skipton frequently feature specialized low-deposit or energy-efficiency-linked deals tailored to getting people on the property ladder.

If you'd like to narrow this down, tell me:I can share more specific product features or help you look at how different lenders calculate affordability. Are you a first-time buyer, home mover, or looking to remortgage? What deposit size or loan-to-value (LTV) ratio are you working with?

The biggest mortgage lenders by market share (what people actually use most) are dominated by a handful of major banks and building societies.

According to the latest UK Finance data for 2024 gross lending (the most recent comprehensive figures available):

• Lloyds Banking Group (includes Halifax and Lloyds Bank) leads with ~19.4% market share (£47bn lent).
• Nationwide Building Society is second at ~17.3% (£41.8bn).
• NatWest Group follows at ~11.2%.
• Barclays (~9.1%), HSBC (~8.2%), and Santander UK (~6.5%) round out the top six.
• Other notable players include building societies like Yorkshire BS, Coventry BS, Skipton BS, and Leeds BS (each 2–4%).

These account for the vast majority of new mortgages issued, so they reflect real-world usage.

Customer satisfaction and service ratings (from Which? surveys of thousands of homeowners) often favour building societies over big banks. Nationwide frequently tops or near-tops these tables with scores around 80–81%, alongside Principality BS and Skipton BS. Major banks like Barclays, First Direct, NatWest, and Santander typically score in the mid-70s.

Which? has named Nationwide (and sometimes Barclays, First Direct, and NatWest) as Recommended Providers based on strong customer scores combined with competitive deals. Building societies generally outperform on service aspects like clarity of statements, flexibility, and overall satisfaction, while big banks often lead on rates or online access.

Top Recommendations

Here are the standout options people commonly use and rate well, balancing popularity (market share), service, and deal competitiveness (rates change frequently, so always compare live):

• Nationwide Building Society — One of the most popular overall (second-largest lender) and consistently highest-rated for customer satisfaction. Strong on competitive rates across buyer types, excellent service scores, and a mutual model (member-owned). Often a Which? Recommended Provider. Good for first-time buyers, movers, and remortgagers.
• Lloyds Banking Group (Halifax/Lloyds) — The single largest lender by volume. Halifax frequently appears in “best deals” tables and awards for categories like new-build or self-employed. Solid high-street presence and product range.
• NatWest — Strong market share and often competitive on remortgages or specific deals. Frequently a Which? Recommended Provider with good customer scores.
• Barclays — Reliable big-bank option with competitive rates in many analyses and solid satisfaction ratings. Often recommended alongside Nationwide.
• HSBC / First Direct — First Direct (part of HSBC) regularly ranks among the cheapest for typical borrowers and scores well on service/online access. HSBC itself is a major player with broad availability.
• Santander — Consistent top-6 lender with competitive fixed-rate deals and decent satisfaction scores.
• Building societies like Skipton, Yorkshire, Coventry, or Principality — These punch above their market share in satisfaction surveys (often 75–81%) and can offer competitive or niche deals (e.g., Skipton for first-time buyers). They appeal if you prioritise service over the biggest high-street names.

Key Advice for Choosing

“Best” is highly personal—it depends on your deposit size (LTV), credit score, whether you’re a first-time buyer, mover, or remortgaging, income type, and current rates/fees. Big lenders dominate volume because they have wide product ranges and branches/apps, but smaller building societies can excel on service or specific scenarios.

Rates and deals shift daily—check comparison sites, Moneyfacts, or use a whole-of-market broker (many are free via lender procuration fees). Look at the full cost (rate + fees + flexibility like overpayments) rather than just the headline rate. Your home may be repossessed if you don’t keep up repayments.

For the latest personalised options, speak to a broker or visit lender sites directly. Nationwide or one of the major banks (Lloyds/Halifax, NatWest, Barclays) are safe starting points for most people due to their scale and track record.

As of October 2026, there isn’t one “best” UK mortgage lender for everyone — the best deal depends on loan-to-value, income, deposit, credit profile, property type, and whether you’re buying, remortgaging or investing. But if you want the brands people actually use, I’d start with these.

Best UK mortgage lenders to check first

My practical “top 10” shortlist

If I were comparing UK mortgages today, I’d make sure these are covered:

1. Nationwide — best all-round starting point, especially for first-time buyers.
2. Halifax — huge market presence and very broker-friendly.
3. HSBC — often sharp on headline rates.
4. first direct — strong for fixed-rate and remortgage deals; Moneyfacts 2026 winner for Best Fixed Rate Mortgage Provider and Best Bank Mortgage Provider. (moneyfactsgroup.co.uk)
5. Santander — strong remortgage/service reputation and major lender.
6. NatWest / RBS — strong for first-time-buyer affordability and a top-three UK lender by 2025 gross lending. (mortgagesolutions.co.uk)
7. Barclays — major lender, and good to check if you need family support via Family Springboard.
8. Yorkshire Building Society / Accord — useful building-society option, especially via brokers.
9. Coventry Building Society / Godiva — strong building-society and buy-to-let presence.
10. Skipton Building Society — especially worth checking for its Track Record mortgage if you rent and have little or no deposit.

Products people actually use

For most UK borrowers, the most common useful product types to compare are:

• 2-year fixed rate — good if you want flexibility and think rates may fall, but remortgage risk comes sooner.
• 5-year fixed rate — good if you want payment certainty for longer; often popular with first-time buyers and families.
• Tracker mortgage — worth considering if you can handle payments changing with Bank of England rate movements.
• Product transfer with your existing lender — often the quickest remortgage route, with fewer checks, but not always the cheapest.
• 95% LTV mortgages — mainstream option for buyers with a 5% deposit.
• Family-assisted mortgages — Barclays Family Springboard is the standout household-name product.
• Higher-income-multiple products — Nationwide Helping Hand is one of the best-known.
• Zero-deposit rental-history products — Skipton Track Record is the best-known, but eligibility is tight.

Bottom line

For a normal residential mortgage, I’d start with Nationwide, Halifax, HSBC, Santander, NatWest, Barclays and first direct. For buy-to-let, start with The Mortgage Works, BM Solutions, NatWest, Godiva/Coventry, Santander, Shawbrook, Aldermore and Paragon. For anything non-standard — self-employed, adverse credit, complex income, unusual property, HMO, limited-company buy-to-let — use a whole-of-market broker, because the “best” lender is usually the one whose criteria fit you, not just the one with the lowest headline rate.

The strongest UK shortlist is Nationwide, Barclays, First Direct, NatWest, Halifax/Lloyds, Santander, Coventry Building Society and HSBC. These are established lenders that borrowers commonly use, but the “best” deal depends heavily on deposit, income, property type, credit record and whether you are a first-time buyer or remortgaging.

Best UK mortgage lenders to compare

• Nationwide Building Society — Excellent all-rounder, especially for first-time buyers, larger loan-to-income cases and borrowers wanting a major building society. It is one of the UK’s largest lenders, alongside Lloyds Banking Group.
• Barclays — Strong mainstream range, including competitive fixed-rate and higher loan-to-value products. It was among the lenders meeting Which?’s recommended criteria.
• First Direct — Often well regarded for customer service and a straightforward digital application process; particularly worth checking if your finances are uncomplicated.
• NatWest — A major high-street lender with a broad range for first-time buyers, movers and remortgagers. It is also frequently used through mortgage brokers.
• Halifax and Lloyds Bank — Major-volume lenders with extensive product ranges and strong branch and broker availability. Halifax is part of Lloyds Banking Group, the UK’s largest mortgage-lending group.
• Santander — A widely used lender with products across mainstream residential borrowing, remortgages and higher loan-to-value lending.
• Coventry Building Society — Worth comparing for competitive rates and flexible underwriting, particularly if you have a non-standard but still straightforward application.
• HSBC — Often competitive on pricing and suitable for borrowers with strong affordability and clean credit histories; it is commonly available both directly and through brokers.
• Leeds Building Society — A useful alternative for borrowers who do not fit every high-street lender’s criteria and for certain specialist property or affordability cases.

Best choices by situation

How to choose the actual product

Compare the total cost, not just the headline rate:

• Initial interest rate and fixed period
• Arrangement or product fee
• Early repayment charges
• Overpayment allowance
• Valuation and legal fees
• Portability if you may move
• Maximum loan-to-value and affordability rules
• Whether the lender accepts your income structure and property type

A mortgage broker can be particularly useful for self-employed applicants, contractors, applicants with variable income, adverse credit, unusual properties or limited deposits. For a straightforward case, comparing lender-direct deals with whole-of-market broker options is sensible.

Avoid choosing solely from customer-service rankings: the cheapest suitable mortgage may come from a lender that is not the best overall brand. Which? found only four surveyed lenders below a 70% customer score—TSB, Virgin Money, Royal Bank of Scotland and Bank of Ireland UK—so lender-specific service differences matter, but eligibility and total cost remain more important.
