SVR stands for Standard Variable Rate. It is the rate your mortgage automatically moves to once your fixed or tracker deal ends, and it is almost always more expensive than the deal you were on.

If your mortgage payment has crept up and you are not sure why, there is a good chance you have quietly slid onto your lender's Standard Variable Rate. It happens to more people than you would think, and it is usually an easy fix once you know what is going on.

In 2026 alone, roughly 1.8 million UK fixed-rate mortgages are due to expire, meaning a huge number of homeowners are at risk of drifting onto their lender's SVR without meaning to.

This blog explains what SVR actually is, why it costs more, how people end up on it, and how to get off it.

What Is SVR?

SVR is the default interest rate your lender charges when you are not on a fixed or tracker deal.

Every mortgage lender has its own SVR. It is set by the lender, not by any external body, though it usually moves in a similar direction to the Bank of England base rate. There is no standard figure, and it varies from lender to lender.

SVR is what your mortgage reverts to automatically when your current deal expires and you have not arranged a new one. You do not choose to go onto it. It just happens.

SVR is usually the most expensive rate a lender offers. That is deliberate. Lenders set it high to encourage you to actively choose a new deal rather than drift along on the default option.

Why Is SVR More Expensive Than a Fixed Rate?

SVR is typically one to three percentage points higher than the fixed rates available on the market at the same time. As of September 2026, the average SVR across UK lenders sits at around 7.1%, while the average two-year fixed rate is closer to 5.6%, and five-year fixes are not far behind. Some lenders' SVRs run even higher, into the 7% to 8% range.

On a £200,000 mortgage balance, the difference between SVR and a competitive fixed rate can mean paying roughly £200 to £500 extra every month. Over a full year, that adds up to £2,400 to £6,000 in extra interest. That is money leaving your account with nothing to show for it.

There is also a certainty problem. A fixed rate locks your payment at the same amount for the agreed period, usually two, three, or five years. SVR can change at any time at the lender's discretion. Your payment could rise with only short notice, and you have no control over when or by how much.

The combination of a higher rate and zero predictability makes SVR the most expensive and least stable place your mortgage can be.

How Do You End Up on the SVR?

Almost always by accident. Your fixed or tracker deal simply comes to an end, and if you have not arranged a new one, your mortgage moves onto the SVR automatically. No one signs up for it. It just happens when nothing else is in place.

The most common reasons are straightforward. People forget their deal end date. They assume the lender will sort it out for them. They assume switching is complicated. Or they assume bad credit means there is no point trying.

Your lender is required to notify you before your deal ends, but the letter is easy to miss among the rest of your post. Many people do not act in time and find themselves on the SVR for weeks or months before they realise what happened.

There is no penalty for being on the SVR itself. It is simply an expensive place to sit, and the fix is usually more straightforward than people expect.

Standard Variable Rate vs Fixed Rate vs Tracker: What Is the Difference?

These are the three main types of mortgage rate, and understanding the difference makes it obvious why SVR is worth avoiding.

Fixed rate. Your interest rate stays the same for an agreed period, usually two, three, or five years. Your monthly payment is predictable and does not change during the fixed term, regardless of what happens to the base rate.

Tracker rate. Your rate moves in line with the Bank of England base rate plus a set margin. Payments can rise or fall, but the mechanism is transparent. You know exactly how your rate is calculated and why it moves.

SVR. Set entirely at your lender's discretion. Can change at any time, usually with only short notice. There is no formula you can follow. It is the least predictable and usually the most expensive of the three.

How Do You Get Off the SVR?

Two main routes, and both are usually more straightforward than people expect.

Product transfer. This means staying with your current lender and moving onto one of their new rate deals. It is often the quickest route because it does not require a full application from scratch. Many product transfers do not involve a new credit check either, since the lender already has your payment history on file.

Remortgage. This means moving to a different lender entirely. It involves a fresh credit and affordability assessment, but it can secure a better rate if your current lender's product transfer options are not competitive.

The two routes also open up on different timelines. The remortgage market, where you switch to a new lender, typically becomes available around six months before your deal ends. Product transfer options with your current lender usually open a little later, more like three to four months before the end date. If you want to compare the whole market, it is worth starting your search early. If you already know you want to stay with your current lender, there is less urgency, but it still pays to check what they are offering as soon as it becomes available.

You do not have to wait until you are already on the SVR to act. Lining up a new deal three to six months ahead means it can kick in the moment your current one runs out, so you skip the SVR altogether.

What Should You Do If You Are on the SVR With Bad Credit?

Being on the SVR with bad credit does not mean you are stuck. It usually just means the product transfer route is worth looking at first.

Product transfers often do not require a new credit check, which removes the biggest barrier for people with credit issues. In many cases, your lender will not ask for fresh income verification or bank statements either, since they already hold your payment history with them. Proof of income may still be requested in some cases, but the process is generally lighter than a full remortgage application.

Even a full remortgage is often still possible with a specialist lender, depending on the type and age of the credit issue. The options are more limited than for someone with clean credit, but they exist and are regularly approved.

How a Broker Helps You Get Off the SVR

A broker compares both routes for you: staying with your current lender or moving elsewhere, so you are not just taking whatever is put in front of you.

A whole-of-market broker checks your current lender's product transfer rates against the wider remortgage market and tells you clearly which option saves you more. Without that comparison, you are guessing.

A broker can also track your deal end date and prompt you to act early, so you avoid spending any time on the SVR at all.

As an FCA-regulated bad credit mortgage broker, we compare both routes properly so you get the best outcome, not just the easiest one.

When Should You Start Looking at Your Options?

Ideally, three to six months before your current deal ends. That gives you enough time to compare options properly and have a new deal ready to start the moment your current one finishes.

Most lenders let you arrange a new deal well in advance. You can lock in a rate today and have it start the day your current deal expires, with no gap on the SVR in between.

If you are already on the SVR, the best time to act is now. Every month you stay on it costs more than switching would. There is no advantage to waiting, and no penalty for leaving the SVR at any time.
