Best mortgage rates UK how to compare and find the right deal

When people search for the best mortgage rates UK lenders currently offer, they're usually hoping to find one clear number. In practice, 'best' is personal. It depends on your deposit, your credit history, how long you want to fix for, and what you're using the mortgage for.

A rate that looks brilliant in a headline might not be available to you at all if you don't meet that lender's criteria for that specific deal. And a slightly higher rate with lower fees can sometimes work out cheaper overall than a market-leading rate with a hefty arrangement fee attached.

Because mortgage rates change frequently, and because your home is used as security for the loan, it's worth comparing properly rather than rushing to the first deal you see advertised. Your home may be repossessed if you do not keep up repayments on your mortgage or any other debt secured on it.

The sections below break down what drives the rate you're offered, how the main rate types compare, and how to work out which deal actually suits your circumstances.

Most UK mortgages fall into one of a few rate types. Understanding how each one behaves helps you weigh up certainty against flexibility.

Fixed rate mortgages

Your interest rate and monthly payment stay the same for an agreed period, usually 2, 3, 5, or 10 years. This makes budgeting easier and protects you if rates rise during that time. The trade-off is that you won't benefit if rates fall significantly, and leaving early usually means paying an early repayment charge.

Tracker mortgages

A tracker rate moves in line with the Bank of England base rate, plus a fixed margin set by the lender. Your payments can go up or down as the base rate changes. Some trackers come without early repayment charges, which gives you more flexibility to switch if a better deal appears.

Standard variable rate (SVR)

This is your lender's default rate. You move onto it automatically once your fixed or tracker deal ends, unless you remortgage first. SVRs are typically much higher than the deals lenders advertise, so it's worth planning your next move before your current deal expires.

Discount variable rate

These offer a discount off the lender's SVR for a set period. They're less common than fixed or tracker deals, and because they move whenever the SVR changes, they're harder to predict.

Your deposit, or the equity you've built up if you're remortgaging, is measured against your property's value as a loan-to-value (LTV) ratio. It's one of the biggest factors in the rate you're offered.

How to work out your LTV: divide your mortgage amount by your property value, then multiply by 100.

For example, on a £300,000 property with a £75,000 deposit, you'd need a mortgage of £225,000. That's an LTV of 75% (£225,000 divided by £300,000, multiplied by 100).

Lenders see lower-LTV borrowers as lower risk, because there's more equity protecting their loan if house prices fall. That's why bigger deposits tend to unlock better rate tiers.

Every few percentage points of extra deposit can move you into a better pricing tier, so it's worth checking whether a larger deposit, even by 5%, would meaningfully change what you're offered.

The type of mortgage you need also shapes the rates available to you.

First-time buyer rates

First-time buyers often have smaller deposits, which can mean a higher LTV and a smaller pool of available rates. That said, lenders compete hard for first-time buyer business, and options like family-assisted or guarantor mortgages can help if you have a small deposit.

Remortgage rates

If you're coming to the end of a fixed or tracker deal, exploring your remortgage options before you roll onto your lender's standard variable rate is usually worthwhile. You can typically lock in a new deal several months ahead of your current one ending.

Buy-to-let rates

Buy-to-let mortgages tend to carry higher rates than residential mortgages, because lenders view rental property as higher risk. Affordability is also assessed differently: lenders usually check that your expected rental income covers a set percentage of the mortgage payment, rather than relying solely on your personal income. Most buy-to-let mortgages also fall outside Financial Conduct Authority regulation, so it's especially important to compare terms carefully before committing.

Beyond deposit and mortgage type, lenders look at a range of personal factors before deciding what rate to offer you.

Your credit history

Lenders check your credit file with agencies such as Experian, Equifax, and TransUnion. A strong credit history generally opens up access to more competitive rates, while missed payments, defaults, or high existing borrowing can mean higher rates or a smaller choice of lenders.

Your income and employment

Lenders assess affordability by looking at your income against your outgoings, and they'll stress-test whether you could still manage payments if rates rose. If you're self-employed, most lenders ask for two to three years of accounts or tax returns, though some accept less for established businesses.

The property itself

Non-standard construction, short leases, or a property above commercial premises can all limit your lender options and affect the rate you're offered.

The deal's features

Rates also vary depending on the length of the deal, the fee structure, and whether the product allows overpayments. A deal with a higher fee sometimes carries a lower rate, and vice versa, which is why comparing the total cost matters more than comparing headline rates alone.

The headline rate is only part of the picture. Fees and the length of the deal both affect the true cost of a mortgage.

Rate versus APRC

The interest rate is the percentage charged on your loan. The APRC (Annual Percentage Rate of Charge) includes the interest rate plus mandatory fees, spread across the whole mortgage term, giving a fuller picture of the overall cost. Two deals with the same headline rate can have very different APRCs once fees are factored in.

A lower rate with a large arrangement fee isn't automatically better value than a slightly higher rate with no fee. Work out the total cost, interest plus fees, over the period you plan to keep the deal, rather than comparing headline rates in isolation.

Many lenders also let you add the arrangement fee to your mortgage balance instead of paying it upfront. This can help with cash flow, but bear in mind you'll pay interest on that fee for the rest of the term.

This is one of the biggest decisions when choosing a mortgage, and there's no universally right answer.

Fixed might suit you if you want:

• Certainty over your monthly payment, regardless of what happens to interest rates
• Easier budgeting for household finances
• Protection if rates rise during your deal

The trade-off is that you won't automatically benefit if rates fall, and leaving early usually triggers an early repayment charge.

Tracker might suit you if you want:

• The potential to benefit if the Bank of England base rate falls
• More flexibility, since many trackers carry no early repayment charge
• A rate that moves transparently in line with the base rate

The trade-off is uncertainty: if the base rate rises, your payments rise with it.
