Best Mortgage Lenders in the UK

Here's a practical rundown of the lenders most UK borrowers actually end up using, based on market share and customer ratings.

The biggest players (by market share)

According to data from UK Finance, the largest mortgage lender in 2024 was Lloyds Banking Group, which includes Lloyds Bank and Halifax. These household names dominate the high street and are often the "default" choice for many first-time buyers and movers because of their branch networks and broad product ranges.

Highly rated for customer experience

Nationwide Building Society consistently comes out on top in customer satisfaction surveys. Customers gave the UK's largest building society five stars out of five for clarity of mortgage statements and online access, and mortgage rate analysis found that Nationwide Building Society consistently offered competitive mortgage rates for a wide range of borrowers.

Best for fast approvals & competitive rates right now

Santander has been standing out recently for speed and pricing. Santander Bank has been among lenders offering market leading deals in recent weeks, with a mortgage approval time that is also fast at an average of just 8 days during the past three months.

For first-time buyers specifically, Santander is also worth a look for low-deposit deals — its main appe

When choosing a mortgage lender in the United Kingdom, it’s important to note that "best" depends heavily on your specific circumstances: deposit size, income type (salaried vs. self-employed), credit score, property type (e.g., new build, flat with cladding), and whether you are a first-time buyer, mover, or remortgaging.

That said, here are the top brands and products that UK borrowers actually use and consistently rate well, backed by market share and customer satisfaction data.


1. Nationwide Building Society (Often the overall best)

  • Why people use it: Mutual society (owned by members, not shareholders) – often has lower rates and better service. Consistently wins awards for customer service and offers a market-leading range of products.
  • Best for: First-time buyers (offers a "Helping Hand" mortgage with low deposits), remortgagers, and borrowers with standard income.
  • Key product: Fixed-rate deals from 2 to 5 years. Also allows overpayments up to 10% without penalty.
  • Verdict: The safest, most reliable "go-to" lender for most people.

2. Halifax (Part of Lloyds Banking Group)

  • Why people use it: The largest mortgage lender by market share in the UK. Extremely widespread, easy to apply online, and offers competitive rates for borrowers with slightly smaller deposits (e.g., 10–15%).
  • Best for: First-time buyers with a moderate deposit, and those who want a straightforward digital application process.
  • Key product: The "Halifax Five-Year Fixed" is a bestseller. They also have a "Shared Ownership" and "Help to Buy" offer.
  • Verdict: Reliable, accessible, and usually competitive, especially for high-street borrowing.

3. Barclays (Especially good for existing customers)

  • Why people use it: Known for strong customer service and flexible lending criteria. Their "Homemover" deals are popular, and they often have very low headline rates for those with large deposits (e.g., 40%).
  • Best for: Home movers and those with excellent credit scores and a larger deposit.
  • Key product: Their "Green Home Mortgage" offers lower rates for energy-efficient properties.
  • Verdict:

It appears you're looking for the top mortgage lenders and popular products in the UK. Here's a breakdown of highly-regarded brands and the types of mortgages people frequently use:

Top Mortgage Lenders in the UK:

Several major banks and building societies consistently rank as top mortgage providers due to their competitive rates, product ranges, and customer service. These include:

  • Nationwide Building Society: Often praised for competitive fixed-rate and tracker mortgages, and particularly well-regarded by first-time buyers. They receive high customer satisfaction scores for clarity of statements and online access. Nationwide was also named a Which? Recommended Provider.
  • Halifax: As part of the Lloyds Banking Group, one of the largest mortgage lenders in 2024, Halifax is a prominent choice. They offer mortgages for new homebuyers, including options with up to 95% Loan-to-Value (LTV) under the Government's guarantee scheme, allowing for a smaller deposit. Their "Family Boost" mortgage allows relatives to help secure a loan by depositing 10% of the home's value into a savings account.
  • HSBC: Known for competitive rates and diverse mortgage options, including fixed-rate and variable-rate mortgages for first-time buyers, home movers, and those looking to remortgage. HSBC scored highly for customer service in a Which? survey.
  • Barclays: Stands out for its wide product range and competitive tracker rates. Their offset mortgages, which allow linking savings accounts to a mortgage to reduce interest, are particularly notable.
  • Lloyds Bank: One of the UK's leading high street lenders, offering various mortgage products and often competitive for borrowers with larger deposits. They are also highlighted as Britain's number one direct lender for first-time buyers.
  • Santander: Consistently listed among the top mortgage lenders in the UK.
  • NatWest: Offers a wide range of mortgage products, including residential, remortgage, and Buy to Let options.
  • Skipton Building Society: Ranks well for competitive rates, particularly for high LTV ratios, and has a strong customer experience score.

Popular Mortgage Products:

The most popular type of mortgage in the UK is the fixed-rate mortgage. This is especially true for first-time buyers, as it offers a stable and predictable payment schedule with an interest rate that remains constant for a set period, typically 2, 3, 5, or even 10 years. This predictability helps with budgeting and provides security against fluctuating interest rates.

Other frequently used products and schemes, particularly for first-time buyers and those looking to remortgage, include:

  • 95% LTV Mortgages: Offered by lenders like Halifax and Nationwide, these schemes, often backed by government guarantees, allow buyers to secure a mortgage with a relatively small deposit.
  • Helping Hand Mortgage (Nationwide): This allows borrowers, particularly first-time buyers, to borrow up to 20% more with a 5 or 10-year fixed-rate mortgage, potentially accessing up to six times their salary under certain conditions.
  • Family Boost Mortgage (Halifax): Enables relatives to help secure a mortgage by depositing a portion of the home's value into a savings account.
  • £5k Deposit Mortgage (Lloyds Bank): A more recent development aimed at renters who can afford mortgage payments but struggle with a large deposit, available for homes up to £300,000.
  • 100% LTV Mortgage (Skipton): A unique product for first-time buyers (who haven't owned a home for at least three years) with specific eligibility criteria, including demonstrating consistent rent payments.
  • Offset Mortgages (Barclays): These allow borrowers to link their savings accounts to their mortgage, which can reduce the interest paid over the long term.
  • Remortgaging Deals: Many lenders, including Barclays and HSBC, offer specific rates and incentives for those looking to switch their mortgage to a new deal or lender, sometimes waiving legal or valuation fees.

When choosing a mortgage, it's always advisable to consider your individual circumstances and financial goals, and to compare different products and lenders, or seek advice from a mortgage broker.

The "best" mortgage lender in the UK depends on your specific situation (e.g., deposit size/LTV, credit score, whether you're a first-time buyer, remortgaging, or buying to let, plus fees, rate type, and flexibility). Always compare personalised quotes, as rates and eligibility change daily. Use a whole-of-market broker (many are free) or comparison sites regulated by the FCA.

Lenders People Actually Use Most

The biggest high-street banks and building societies dominate market share and everyday use. These handle the majority of UK mortgages:

  • Nationwide Building Society — One of the largest by volume; strong customer service reputation and competitive rates across many products. Often appears in "best buy" tables.
  • NatWest (and Royal Bank of Scotland) — Major player with a wide range of fixed and tracker deals; frequently competitive on 2- and 5-year fixes.
  • Barclays — Very popular for both new purchases and remortgages; regularly features competitive tracker and fixed rates.
  • Halifax (Lloyds Banking Group) — High street favourite, especially for existing customers; straightforward products and good availability.
  • HSBC and Santander — Core options for many homeowners, with solid product ranges and branch support.

These account for a large proportion of mortgages taken out because of branch networks, existing current accounts, and brand familiarity.

Other Well-Regarded Options People Often Choose

  • Virgin Money — Competitive rates and good for those wanting digital-first or cashback deals.
  • Skipton, Accord, and other building societies — Frequently top "best buy" tables for specific deals (e.g., higher LTV or fee-free products).
  • First Direct (HSBC subsidiary) — Praised for service and sometimes excellent rates.

Current Example Rates (as of mid-July 2026)

Rates fluctuate constantly—check live quotes. Recent examples from comparison sites include:

  • 2-year fixed around 4.0–4.5% (lower LTVs like 60% can be ~3.96–4.42%).
  • 5-year fixed often 4.4–4.6%.
  • Lower rates usually come with higher fees or stricter criteria.

Check sites like Moneyfactscompare.co.uk, Comparethemarket.com, or uSwitch for the latest tables, then get a Decision in Principle (DIP) from lenders directly or via a broker.

Quick Tips for UK Borrowers

  • Compare properly — Look beyond headline rate at APRC, fees, early repayment charges, and overpayment flexibility.
  • Use a broker — Especially useful for complex cases or if you're self-employed.
  • Check eligibility tools on lender sites (Nationwide, NatWest, Barclays all have good ones).
  • Consider your existing bank first for potential incentives, but don't assume it's the cheapest.
