What the standard variable rate really costs you

The standard variable rate is the default rate your mortgage falls onto when a fixed or tracker deal ends. It's set at the lender's discretion and is typically far higher than anything available on a new deal — average SVRs were near 6.49% in mid-2026 while the best fixed rates sat in the mid-4s. There is normally no penalty for leaving an SVR, which makes it the easiest expensive mistake to fix.

What the SVR actually is

Answer first: the standard variable rate is your lender’s default rate — the one your mortgage falls onto when your fixed or tracker deal ends. You don’t choose it. You land on it, by not doing anything.

It isn’t a product with a rate anyone negotiated on your behalf, and it doesn’t track the base rate in any mechanical way — the lender sets it at its own discretion. And it is, almost without exception, far more expensive than anything on offer to a new customer.

The size of the gap

In mid-2026, average SVRs sat near 6.49%, while the best available fixed rates were in the mid-4s. That’s a gap of roughly two percentage points.

Two points doesn’t sound dramatic until you apply it to a mortgage balance. On a substantial loan, it translates into hundreds of pounds a month — money that buys you nothing at all. Not certainty, not flexibility, not a feature. It’s simply the price of not having switched.

Run your own figures through the remortgage calculator, entering your SVR as the current rate. For most people the result is uncomfortable reading, which is exactly why it’s worth doing.

Nothing is holding you there

Here’s the part that makes SVR drift so frustrating: there’s normally no early repayment charge on an SVR. Your deal has ended. The tie-in has expired. You are entirely free to remortgage or take a product transfer whenever you choose.

Compare that with someone mid-fix, who’d have to weigh a penalty against the saving. They have a real decision to make. If you’re on the SVR, you don’t — you have an unforced error to correct, and correcting it costs you nothing but the switching process.

Why so many people end up there

Not because they decided to. Because the SVR is the default, and defaults win.

A fixed rate ends quietly. The lender writes to say so, the letter arrives among everything else, and life is busy. There’s no dramatic moment — just a payment that goes up, sometimes gradually enough that it doesn’t demand attention. And around 1.8 million fixed deals expire during 2026, which means an enormous number of households are walking into exactly this.

Some people also stay deliberately, thinking they’ll “wait for rates to fall before fixing.” That reasoning inverts the maths: you’re paying a premium of roughly two points every month while you wait, in the hope of saving a fraction of that later. Waiting on the SVR is the most expensive way to be patient.

What to do about it

If you’re on the SVR now: act. This is the highest-value, lowest-risk change available in the mortgage market, and there’s no penalty for making it. Compare a remortgage against a product transfer with your existing lender, and pick on total cost. How to remortgage sets out the process.

If your deal ends within six months: start now. Offers typically stay valid for three to six months, so you can line up a new rate and have it complete the day your old one expires — never touching the SVR at all. See when to remortgage.

If your deal ends later: diarise the date, six months ahead of it. That one calendar entry is worth more than any rate forecast you’ll read this year.

The contractor trap

There’s a version of this that’s specific to contractors, and it’s worth naming because it catches a lot of people.

You took your mortgage as an employee. Since then you’ve gone self-employed, contracting, or limited. Your deal ends — but your existing lender’s renewal process can’t read a day rate, so it offers you a poor product transfer rate, or your application stalls. You conclude you’re stuck, and you stay on the SVR.

Stuck is exactly what you are not. You are simply at the wrong lender. Elsewhere in the market sit lenders that apply contract-based underwriting, pricing from the gross day rate in your contract rather than the modest profit your accountant reports — and they will frequently lend more, at a keen rate, in the very situation where your current lender declines. Remortgaging as a self-employed contractor covers the move.

Believing you’re trapped on the SVR because one lender can’t read your income is the most expensive misunderstanding in contractor lending.

The bottom line

The SVR is the lender’s default rate, set at its discretion, and typically around two percentage points above the best deals available — a gap that costs hundreds a month on a normal balance. There’s normally no penalty for leaving it, so if you’re on it, this is the easiest money you’ll save this year. And if you’ve been told you can’t switch because of how you earn, get a second opinion from a lender that understands contract income. Speak to an adviser.
