Standard Variable Rate Mortgages: What They Cost, Why They Cost More and How to Switch

This guide explains what the standard variable rate is, why it is almost always more expensive than a fixed or tracker deal, and how to switch to a more competitive product. If your mortgage deal has recently ended or is about to end, understanding the SVR and your options for avoiding it could save you a significant amount each month.

Your home may be repossessed if you do not keep up repayments on a mortgage or any other debt secured on it.

What Is the Standard Variable Rate

The standard variable rate is the default interest rate that your lender charges once your initial mortgage deal — whether fixed, tracker or discount — comes to an end. Every lender sets its own SVR, and it can be changed at any time, by any amount, at the lender’s discretion. You do not need to agree to the change; it takes effect automatically.

The SVR is not directly linked to the Bank of England base rate. While most lenders adjust their SVR broadly in line with base rate changes, the relationship is not guaranteed. A lender could hold its SVR steady after a base rate cut, or increase it independently of the base rate. This makes the SVR less transparent than a tracker mortgage, where the link to the base rate is contractual.

The Bank of England base rate stood at 3.75 per cent following the Monetary Policy Committee’s decision on 19 March 2026. The next MPC decision is due on 30 April 2026.

How Much More Does the SVR Cost

The average SVR across UK lenders was approximately 7.15 per cent in April 2026, according to Moneyfacts. Individual lender SVRs ranged from around 6.31 per cent at Newcastle Building Society to 8.38 per cent at Aldermore. By comparison, the average two-year fixed rate was approximately 5.9 per cent and the average five-year fixed rate was approximately 5.78 per cent.

On a £200,000 repayment mortgage over 25 years, the difference between a rate of 5.9 per cent and an SVR of 7.15 per cent amounts to approximately £160 per month, or around £1,920 per year. On larger mortgages, the annual cost of remaining on the SVR is proportionally higher.

Around 1.8 million fixed-rate mortgages are due to expire during 2026, according to UK Finance. Borrowers who do not remortgage before their deal ends will automatically move onto their lender’s SVR.

Why Borrowers End Up on the SVR

Most borrowers do not choose the SVR. They end up on it because their fixed-rate, tracker or discount deal has expired and they have not yet arranged a replacement product. This can happen for several reasons:

•       Inaction or lack of awareness. Some borrowers do not realise their deal is ending or underestimate how much the SVR will add to their costs.

•       Difficulty qualifying for a new deal. If your income, credit profile or property value has changed since you took out the original mortgage, you may find it harder to pass lender affordability checks for a new product.

•       Short-term planning. If you are about to sell the property or expect your circumstances to change in the near future, you may decide that the SVR is acceptable for a brief period rather than committing to a new deal with arrangement fees and potential early repayment charges.

•       Mortgage prisoners. A small number of borrowers are unable to switch because their current lender no longer offers new deals or because changes in lending rules mean they no longer meet the affordability criteria of other lenders, even though they have never missed a payment.

When the SVR May Be Acceptable for a Short Period

There are limited circumstances where remaining on the SVR for a short period may be a reasonable choice:

•       You are selling the property within a few months and do not want to commit to a new deal with early repayment charges.

•       You intend to make a large overpayment or repay the mortgage in full shortly. Most SVRs allow unlimited overpayments without penalty.

•       You are between deals and waiting for a new product to complete. In this case, the SVR acts as a temporary bridge rather than a long-term arrangement.

In most other circumstances, switching to a fixed-rate, tracker or discount deal will produce lower monthly payments. Mortgage One’s fixed-rate mortgage guide explains how fixed deals work and how to choose between different term lengths.

How to Switch Away From the SVR

If you are on the SVR or approaching the end of a deal, you have two main routes to a new product:

Product transfer. Your existing lender may offer you a new fixed or tracker rate without a full application. Product transfers are usually quicker and involve less documentation than a full remortgage, but you are limited to that lender’s range. A broker can tell you whether the product transfer rate is competitive or whether the wider market offers something more suitable.

Remortgage. Moving your mortgage to a new lender gives you access to the full range of products across the market. A remortgage involves a new application, affordability assessment, property valuation and legal work. Mortgage One’s remortgaging guide explains the full process and typical timescales.

Many lenders allow you to secure a new deal up to six months before your current product expires. Starting early means you can lock in a rate without committing, and switch to something more competitive if pricing improves before completion.

If you are currently on the SVR and not tied to any early repayment charges, you can remortgage immediately. There is no fixed term to wait out.

Comparing Your Options

When switching from the SVR, you will typically choose between a fixed rate, tracker or discount mortgage. Each has different characteristics:

•       A fixed-rate mortgage locks in your rate for an agreed term, giving you certainty over your monthly payments.

•       A tracker mortgage follows the Bank of England base rate by a fixed margin. Mortgage One’s tracker mortgage guide explains the mechanics and risks.

•       A discount mortgage offers a reduction on the lender’s SVR for an initial period. Mortgage One’s discount mortgage guide covers how these differ from trackers.

How Mortgage One Can Help

Switching away from the SVR is one of the most straightforward ways to reduce your mortgage costs, but the right replacement product depends on your loan size, LTV, income, plans and risk tolerance. As a whole of market mortgage broker, Mortgage One can compare both product transfer rates from your existing lender and remortgage options across the wider market to identify the most suitable structure.

If you have been unable to switch because of affordability constraints or changes in your circumstances, Mortgage One can assess whether specialist lenders or alternative product structures may help. Mortgage One’s mortgage application guide explains the documentation and process involved.

FAQs

1. What is a standard variable rate mortgage?

The standard variable rate is the default interest rate your lender charges once your initial mortgage deal ends. It is set by the lender and can be changed at any time, by any amount, at the lender’s discretion.

2. Why is the SVR higher than fixed and tracker rates?

The SVR is a revert rate, not a competitive product designed to attract new business. Lenders set it higher because borrowers on the SVR are not locked into a deal and can leave at any time without early repayment charges. The higher rate reflects the lender’s pricing of that flexibility.

3. Can I leave the SVR at any time?

Yes. Because the SVR has no fixed term and no early repayment charges, you can remortgage to a new lender or take a new deal with your existing lender at any time without penalty.

4. How do I know if I am on the SVR?

Check your most recent mortgage statement or contact your lender. If your original fixed, tracker or discount deal has expired and you have not arranged a new product, you are almost certainly on the SVR.

5. What is a product transfer?

A product transfer is when you switch to a new rate with your existing lender without moving your mortgage to a different lender. It is usually quicker and involves less paperwork than a full remortgage, but your choice is limited to that lender’s products.

6. How much could I save by switching from the SVR?

The amount depends on your mortgage balance and how much higher your SVR is than the deal you switch to. On a £200,000 mortgage, the difference between a typical SVR of around 7 per cent and a fixed rate of around 5.9 per cent could amount to approximately £160 per month.

7. What if I cannot pass affordability checks for a new deal?

Some borrowers find they cannot meet the affordability criteria of new lenders, even if they have never missed a payment. A broker with access to the whole market can identify lenders with more flexible criteria, or explore whether a product transfer with your existing lender is possible.

8. Should I fix or track when leaving the SVR?

This depends on your view on future rate movements, your appetite for payment variability and your financial plans. A fixed rate gives certainty; a tracker gives potential to benefit from base rate cuts but carries the risk of increases. A broker can model both scenarios for your specific circumstances.
