Accord

As of September 2026, I’d shortlist these UK mortgage lenders first. I’m not saying any one lender is “best” for everyone — mortgage pricing changes daily and depends heavily on your LTV, income, credit file, property type, term, fees and whether you’re buying or remortgaging. But these are the brands that are both widely used and repeatedly show up in market-share, rate, service or awards data.

Best UK mortgage lenders to check first

My practical “top 10” shortlist

If I were comparing as a UK borrower, I’d start with:

1. Nationwide Building Society — best all-rounder; strong for first-time buyers and customer satisfaction.
2. Halifax — huge market presence, broad criteria, strong service recognition.
3. Lloyds Bank — big mainstream lender; often worth checking direct as well as via broker.
4. NatWest — strong remortgage/product-transfer option.
5. HSBC — often competitive for lower-risk borrowers and remortgages.
6. first direct — strong rate-led option, especially fixed-rate and remortgage deals.
7. Barclays — good to check for large loans, home movers and mainstream cases.
8. Santander — good online/service reputation and regularly competitive.
9. Yorkshire / Coventry / Leeds / Skipton building societies — worth checking, especially where criteria or niche products matter.
10. The Mortgage Works / Paragon / Aldermore / Pepper / Kensington / Accord — not necessarily “mainstream best buys”, but important for buy-to-let, self-employed, complex or adverse-credit cases.

Products most people should compare

For a standard residential mortgage, compare these by total cost over the deal period, not just the headline rate:

• 2-year fixed — more flexibility if you expect rates to fall or may move soon.
• 5-year fixed — more payment certainty; often popular for households wanting stability.
• Tracker / variable deals — only if you can afford payments rising.
• Product transfer with your existing lender — often simpler and may avoid a full remortgage process.
• Offset mortgage — useful if you hold substantial cash savings; Coventry is a well-known name in this area.
• Green mortgage / green reward — check if your property is energy efficient or you’re buying a new-build; lenders such as Barclays, HSBC, Nationwide, Virgin Money and Yorkshire BS have had green-related products. (which.co.uk) |

How I’d actually choose

Use a whole-of-market mortgage broker and also compare direct-only deals yourself. MoneyHelper says shopping around with a whole-of-market broker can make sense, especially if you’re comparing options across the market, and MoneySavingExpert recommends comparing a broker’s best result against deals the broker may not have access to. (moneyhelper.org.uk)

For most borrowers, the “best” deal is usually the one with the lowest true cost after adding:

• interest rate
• arrangement/product fee
• valuation fee
• legal fees or cashback
• early repayment charges
• overpayment flexibility
• portability if you may move
• likelihood of approval based on your circumstances

And the standard UK warning applies: your home may be repossessed if you do not keep up repayments on your mortgage.

Best Mortgage Lenders in the UK (2026)

Here's a practical breakdown of who actually dominates the UK mortgage market and where different lenders shine:

The "Big Six" — Where Most People Actually Get Mortgages

A handful of lenders account for the vast majority of UK mortgage lending. The largest mortgage lenders in the UK are often called the Big Six: Lloyds Banking Group (which includes Halifax), Nationwide, NatWest Group, Santander, Barclays and HSBC. Between them, they account for most of the mortgage lending in the UK.

Lloyds Banking Group (Lloyds Bank / Halifax) — Currently the market leader. According to data from UK Finance, the largest mortgage lender in 2024 was Lloyds Banking Group, which includes Lloyds Bank and Halifax. Even as the market grew rapidly, total gross lending reached £282.1 billion in 2025, up 20.1% on the year before, and while Lloyds grew slowest of the six at 11.1%, it still held onto first place — showing sheer scale/loyalty even without leading on growth.

Nationwide Building Society — The UK's biggest building society and a strong all-rounder. Customers gave the UK's largest building society five stars out of five for clarity of mortgage statements and online access, and Which?'s mortgage rate analysis found Nationwide consistently offered competitive mortgage rates for a wide range of borrowers. Notably, Nationwide bought Virgin Money, and Virgin Money's business transferred to Nationwide on 2 April 2026, consolidating its position further.

Santander — Known for aggressive high loan-to-value (LTV) deals, making it popular with first-time buyers. Santander's main appeal lies in its aggressive approach to high loan-to-value lending, making it one of the best mortgage lenders for first-time buyers, particularly for those with a reliable income but who find saving for a 5% or 10% deposit a near-impossible task. It's also been growing fastest among the big lenders: Santander grew fastest of the six at 57.6%. Forbes also notes Santander has been among lenders offering market leading deals in recent weeks, with a fast average mortgage approval time of just 8 days.

Barclays, HSBC, NatWest — Round out the Big Six, all offering broad direct-to-consumer ranges with competitive standard rates, extensive branch networks, and strong digital banking integration (useful if you already bank with them).

Strong Alternatives — Often Beat the Big Six on Rates/Criteria

Below the Big Six sit mortgage lenders such as Coventry Building Society, Skipton and Accord, which lend on a smaller scale but put out competitive deals and often win on criteria. Worth noting: Accord is intermediary-only, so you can reach it through a broker but not directly.

Something to Watch

Clydesdale, part of the same group as Nationwide/Virgin Money, stopped all new residential mortgage lending in July 2026 after 188 years, with new business moving to the Nationwide and Virgin Money brands instead — a reminder that even long-standing brands can disappear from the mortgage market.

How to Actually Find the Best Deal for You

Rather than picking a "best" lender in the abstract, it's worth noting that the best mortgage lender for you will depend on your individual circumstances — some lenders are more willing to give mortgages to self-employed homebuyers, while others specialise in guarantor mortgages or solutions for people with credit issues.

Practical tip: Since 96% of all new mortgage lending is now taken on a fixed rate
