Should I Remortgage or Stay on My SVR?

What Is the SVR and Why Does It Matter?

The standard variable rate (SVR) is your lender's default interest rate. It is the rate you automatically move to when your fixed, tracker, or discount deal expires. Each lender sets their own SVR, and it can change at any time — typically in response to Bank of England base rate decisions, though lenders are not obligated to pass on changes in full.

SVRs are consistently among the highest rates on the market. While the best fixed rates might be in the region of 4% to 5%, SVRs commonly sit between 6% and 8% or even higher. On a typical UK mortgage, this difference translates to hundreds of pounds extra per month in interest payments.

Despite this, a significant number of UK homeowners remain on their lender's SVR. Some are unaware they have moved onto it, while others assume the hassle of remortgaging is not worth it. In the vast majority of cases, taking the time to remortgage will result in meaningful savings.

When Remortgaging Is the Better Option

For most homeowners, remortgaging away from the SVR is the clear winner. If you plan to stay in your home for at least two more years, securing a new fixed or tracker deal will almost certainly save you money. Even after accounting for arrangement fees, valuation costs, and legal fees — many of which are often covered by the new lender — the savings from a lower rate typically far outweigh the costs.

Remortgaging is particularly beneficial if you have built up equity in your property. A lower loan-to-value ratio means access to better rates, which can amplify your savings. For example, moving from a 75% LTV bracket to a 60% LTV bracket could shave a noticeable amount off your interest rate.

If your financial circumstances have improved since you took out your original mortgage — perhaps through a higher income, a better credit score, or reduced debts — you may now qualify for deals that were previously unavailable to you. This is another strong reason to explore the market rather than staying on the SVR.

When Staying on the SVR Could Make Sense

There are a few niche scenarios where the SVR might actually be the pragmatic choice. If you are planning to sell your home within the next few months, taking on a new fixed rate deal — and the fees that come with it — may not be worthwhile. The SVR gives you complete flexibility to redeem your mortgage at any point without early repayment charges.

Similarly, if you have a very small mortgage balance, the arrangement fees for a new deal could represent a disproportionate cost. On a balance of 30,000 pounds, a 1,000-pound arrangement fee is equivalent to over 3% of your mortgage, which might negate the interest savings over a short deal period.

The SVR also offers maximum flexibility for overpayments. While most fixed rate deals allow overpayments of up to 10% of your balance per year, the SVR typically has no such restrictions. If you have come into a lump sum and want to pay down your mortgage aggressively, the SVR allows you to do so without penalty.

How to Calculate Which Option Saves You More

To make an informed decision, you need to compare the total cost of staying on the SVR against the total cost of remortgaging. Start by calculating your current monthly SVR payment and multiply it by the number of months you expect to remain on it. Then calculate what your monthly payment would be on a new deal, including any fees spread over the deal period.

For example, if your SVR payment is 1,200 pounds per month and a new two-year fix would cost 900 pounds per month plus a 1,000-pound fee, the calculation is straightforward. Over two years, the SVR costs 28,800 pounds in total payments, while the fixed rate costs 22,600 pounds (21,600 plus the 1,000 fee). The saving from remortgaging would be 6,200 pounds.

If you are unsure about the numbers, a mortgage broker can run these calculations for you and present a clear comparison. Many brokers also have online calculators on their websites that allow you to input your details and see the potential savings instantly.
