Your 2-year fixed mortgage rate: where it stands and what it means

The standard variable rate is 6.58%, and the two-year fixed deal has moved a long way since late 2025. Here is what that gap means for your monthly payment.

The fixed rate has climbed since late 2025

The two-year fixed mortgage market has shifted noticeably over the past year. In October 2025, the average rate for a deal with a 60% loan-to-value stood at 4.03%. By September 2026, that figure had risen to 5.01%. This represents an increase of nearly a full percentage point in just twelve months. Borrowers with smaller deposits have also seen rates climb. At a higher loan-to-value, the average rate moved from 4.2% to 5.13% over the same period. Those with the highest loan-to-value saw a similar pattern, with rates rising from 4.31% to 5.26%.

These consistent increases across different deposit sizes indicate a broad market movement rather than an isolated change for one group of borrowers. It is important to remember that these figures are advertised market averages. They are calculated by weighting the rates banks and building societies advertised by the volume of products taken out. This makes them a useful benchmark for tracking how the market has moved over time. However, they do not represent the specific offer any individual will receive. Your actual rate will depend on your lender, credit history and the size of your deposit, so your quote may sit above or below these national averages.

Worked example: what 6.58% does to a typical mortgage

To see how the standard variable rate affects your payments, consider a mortgage balance of £250,000 with 25 years remaining. Using the Bank of England’s September 2026 rate of 6.58% as the interest rate, the monthly repayment is £1,700.54. Over the full term, the total interest paid is £260,160.94. These figures are based on the stated assumptions and standard arithmetic.

If you overpay £100 a month, the total interest drops to £221,752.59. This saves you £38,408.35 in interest and clears the loan 37 months sooner, cutting the term by about 3.1 years. While this extra payment helps, the interest rate itself is the primary driver of your costs. The 6.58% figure serves as a market benchmark, but your actual rate will vary based on your lender and credit history.

What the standard variable rate actually means

The 6.58% standard variable rate is the revert-to rate your mortgage lands on when a fixed deal ends. It is not a price any one person will receive, but a weighted market average of advertised rates from banks and building societies. This level was unchanged in August 2026 and stands down 0.22 points on September 2025. While the rate has been relatively stable recently, it remains well above current fixed deals. The gap between your fixed rate and this standard variable rate is a rough guide to what you are saving each month while the fixed period is live. However, this depends on your specific deal, not just the market average. Some products also carry early repayment charges if you switch early.

What to do before your fixed deal ends

Start by calculating your loan-to-value. Divide your remaining mortgage balance by your home’s current market value. This ratio is crucial because lenders use it to determine which deals are available to you. Next, record your current fixed rate and count exactly how many months remain on your existing deal. Knowing this timeline helps you decide whether to act immediately or wait for a better window.

Compare your current fixed rate against the standard variable rate mentioned earlier. This gap shows how much you are saving each month while your fixed deal is live. If you are within a few months of your deal ending, do not wait. Get a remortgage quote before the deal lapses. This ensures you have options ready and avoids the risk of being stuck on a higher rate. Acting early gives you leverage and prevents last-minute pressure.
