What Is a Standard Variable Rate (SVR)?

A standard variable rate, or SVR, is the interest rate your lender moves you onto when your fixed, tracker or discount deal ends. It is usually one of the most expensive rates your lender offers, and rolling onto it by accident can add hundreds of pounds to your monthly payment. This guide explains what the SVR is, why it is so high, and how to avoid being caught out.

Key takeaways

• The SVR is the fallback rate you are switched to automatically when your fixed or tracker deal finishes, unless you arrange a new one.
• Each lender sets its own SVR, and it is not directly tied to the Bank of England base rate, so it can change at any time, by any amount.
• It is usually expensive. In 2026, average SVRs sit around 7% to 8%, well above the best fixed deals.
• You can leave it whenever you like. Unlike a fixed deal, an SVR has no early repayment charge, which is its one genuine advantage.

What is a standard variable rate?

Every lender has a standard variable rate. It is their default interest rate, and it is where your mortgage lands once your introductory deal ends, unless you have lined up a new one. If you took a two-year fix and did nothing when it finished, you would roll onto your lender's SVR the following month.

Because it is a fallback rather than a deal you chose, the SVR is rarely competitive. Lenders do not need to make it attractive, since borrowers usually end up on it by default rather than by shopping around.

How does an SVR work?

An SVR is a variable rate, so your monthly payment can go up or down over time. The important thing to understand is who controls it: the lender does. An SVR is not a tracker, so it does not automatically follow the Bank of England base rate. A lender can raise or cut its SVR at any time, for any reason, and often only some of a base rate change is passed on.

That makes the SVR unpredictable. When the base rate falls you may not get the full benefit, and when it rises your lender can increase the SVR by more. You can see where the base rate sits today on our UK interest rates page, but remember your SVR is set separately.

Why is the SVR so high?

The SVR builds in a healthy margin for the lender on top of their funding costs, which is why it typically sits well above the fixed and tracker deals on offer. In 2026 many lenders' SVRs are in the 7% to 8% range, while a decent fixed deal can be a couple of percentage points lower.

On a £200,000 mortgage, the gap between an 8% SVR and a 5% fixed rate is roughly £350 a month. You can see the effect of different rates for your own loan with the mortgage calculator.

Should you stay on the SVR?

For most people, no. Because it is usually the priciest option, staying on the SVR month after month can cost thousands a year compared with remortgaging to a new deal. If you have drifted onto it, it is worth acting sooner rather than later.

That said, the SVR has one real upside: flexibility. There is no early repayment charge, so you can overpay as much as you like or leave whenever you want. That can suit you if you are about to sell, expecting a lump sum, or planning to overpay your mortgage heavily in the short term. For most other situations, a fixed or tracker deal will be cheaper.

How to avoid rolling onto the SVR

Avoiding the SVR is mostly about timing:

• Diarise your deal's end date. You can usually line up a new rate three to six months in advance.
• Consider a product transfer. Your existing lender may offer you a new deal with less paperwork than a full remortgage, though it is worth comparing it against the wider market.
• Remortgage if it is cheaper. Switching lender can unlock a better rate. See how easy it is to switch mortgages.
• Do not just let it lapse. Doing nothing is what lands you on the SVR in the first place.

SVR versus a tracker

They are both variable, but they behave differently. A tracker mortgage follows the Bank of England base rate by a set margin, so its moves are transparent and predictable. An SVR is set entirely at the lender's discretion. A tracker is usually the better choice if you want a variable rate you can understand.

Frequently asked questions

Is the SVR the same as the base rate?

No. The Bank of England base rate is set by the Bank; the SVR is set by your lender and is typically several percentage points higher.

Can my lender change the SVR whenever they want?

Yes. That is the main risk of being on it. They can raise or lower it at any time, and are not obliged to match base rate changes.

Is there any benefit to being on the SVR?

Flexibility. There is no early repayment charge, so you can overpay freely or switch away at any time without penalty.
