The standard variable rate is where your mortgage ends up if you do nothing when a deal ends, and it is usually the most expensive place to be. This guide explains the standard variable rate: what it is, when you are on it, why it is costly, and why most people move off it as soon as they can.

What the standard variable rate is

The standard variable rate, or SVR, is a lender's default interest rate, set by the lender itself. It is the rate your mortgage reverts to when an initial deal, such as a fixed or tracker rate, comes to an end. Each lender sets its own SVR, and it can change at any time at the lender's discretion, which makes it different from the more predictable tracker or fixed rates.

When you are on it

You end up on the standard variable rate when your initial deal ends and you do not arrange a new one, as our guide to what happens when your fixed rate ends explains. At that point, the mortgage automatically moves onto the SVR. You can also choose to sit on it temporarily, for example if you want flexibility before remortgaging or moving, since it usually has no early repayment charge.

Why it is expensive

The standard variable rate is typically much higher than competitive fixed or tracker deals. In mid-2026, average standard variable rates are around 7%, well above the best available deals. On a typical mortgage, being on the SVR can add hundreds of pounds to monthly payments compared with a new deal, for exactly the same loan. This is why the SVR is usually the costliest place for a mortgage to sit.

Set by the lender

Unlike a tracker, which follows the Bank of England base rate transparently, the standard variable rate is set by the lender at its own discretion. It is often influenced by the base rate but does not have to move in step with it, so it can stay high even if the base rate falls, as our guide to discount mortgages notes. This lender control is part of why the SVR is unpredictable.

Flexibility but at a price

One feature of the standard variable rate is flexibility: it usually has no early repayment charge, so you can overpay, switch or repay at any time without penalty. This can suit someone planning to move or repay very soon and wanting to avoid being tied in. But this flexibility comes at the high SVR price, so for most people it is not worth staying on the SVR for long.

Why to leave it

For most borrowers, the standard variable rate is somewhere to leave as soon as possible, by remortgaging to a new deal, since almost any competitive fixed or tracker rate will be cheaper, as our guide to choosing between fixed and variable explains. Every month on the SVR tends to cost more than necessary, so moving off it promptly is one of the most valuable things a homeowner can do.

Discounts and the standard variable rate

The standard variable rate also matters because discount mortgages are priced as a set amount below it. So if you have a discount deal, your rate depends on the lender's standard variable rate, which can change at the lender's discretion. Understanding the SVR therefore helps you understand discount deals too, and why a large discount off a high standard variable rate may not be as cheap as it first appears.

How lenders set the SVR

Each lender sets its own standard variable rate and can change it when it chooses. While it is often influenced by the Bank of England base rate, lenders are not obliged to move it in step, so an SVR can stay high even when the base rate falls, or rise for the lender's own reasons. This discretion is why the SVR is unpredictable and usually higher than market deals.

The SVR versus the base rate

It is a common misconception that the standard variable rate simply follows the base rate. In fact, unlike a tracker, which is tied to the base rate, the SVR is at the lender's discretion, as our guide to trackers explains. So a base rate cut does not guarantee a lower SVR. This difference is important when deciding whether to stay on an SVR or move to a tracker or fix.

When sitting on the SVR makes sense

Occasionally the SVR's flexibility, usually with no early repayment charge, can suit someone planning to move or repay very soon, who wants to avoid being tied into a deal for a short period. For a brief bridge, the higher rate may be worth the freedom. But as a place to settle, the SVR is rarely worthwhile, so this only makes sense for short, specific situations.

An example of the cost

The cost of the SVR can be stark. On a £200,000 mortgage, the difference between an SVR of around 7% and a competitive fix can be hundreds of pounds a month. Over a year on the SVR, that adds up to a large sum paid unnecessarily. Seeing the figures makes clear why moving off the SVR promptly is one of the most valuable steps a borrower can take.

Do not drift onto it

The most common way people end up on the SVR is simply by not acting when their deal ends, drifting onto it by default. Setting a reminder before your deal ends, and arranging a new deal in good time, avoids this, as our guide to timing your remortgage explains. A little planning ensures you never pay the high SVR through inaction.

Reverting and remortgaging

The standard variable rate matters most as the rate you revert to, which is why remortgaging exists. By switching to a new deal as your current one ends, you avoid the SVR and keep your payments down, as our guide to remortgaging explains. Treating the end of every deal as a prompt to remortgage, rather than letting the mortgage revert by default, is the key to never paying the SVR for long.

In essence, the standard variable rate is best understood as the costly default to be avoided, a safety net that catches your mortgage when a deal ends but one you should step off quickly by arranging a new, cheaper deal.

The single most useful thing to remember is simple: the standard variable rate is almost never where you want your mortgage to stay, so set a reminder before each deal ends and switch in good time, and you will keep your payments where they should be rather than paying the SVR premium by accident.

In short

The standard variable rate is the lender's default rate, set at its discretion, that your mortgage reverts to when a deal ends. It is usually much higher than competitive deals, averaging around 7% in mid-2026, so it can add hundreds to monthly payments. It offers flexibility with no early repayment charge but at a high price. Most people should remortgage off it promptly to a cheaper deal.
