Should You Remortgage or Stay on Your Lender’s SVR?

Last updated: 29 July 2026

1.8 million fixed-rate mortgages are set to expire in 2026, according to UK Finance. If yours is one of them, and you do nothing, your lender will silently move you onto their Standard Variable Rate. The average SVR across major UK lenders in July 2026 is 7.13%, according to Moneyfacts. The best five-year fixed rates start below 4% for borrowers with decent equity. That gap, on a £200,000 mortgage, is roughly £350 per month. Every month you sit on the SVR without switching, that’s money gone.

But “just remortgage” isn’t always the right answer. If you’re planning to sell within six months, if your remaining balance is under £50,000, or if you’d face early repayment charges that wipe out the savings, staying put might actually cost less. This guide runs the numbers for both sides so you can see exactly where the break-even sits for your situation.

What Is an SVR and Why Are You on It?

An SVR is the default interest rate your lender charges once your fixed, tracker, or discounted deal expires. Every lender sets their own SVR and can change it whenever they want, without needing to follow the Bank of England base rate. It’s not a “deal” you chose. It’s where you end up when your actual deal runs out and you haven’t arranged a replacement.

Current SVRs at major UK lenders tell the story. Halifax charges 6.99%. Nationwide sits at 6.74%. NatWest charges 7.24%. Santander is at 7.25%. Barclays charges 7.49%. These are rates that homeowners who locked in at 1.5% to 2% in 2021 are now being moved onto. The monthly payment shock is real. On a £250,000 mortgage with 20 years remaining, moving from a 1.8% fix to a 7.25% SVR pushes the payment from roughly £1,240 to £1,980. That’s £740 per month more, or £8,880 per year.

What Is Staying on the SVR Actually Costing You?

The simplest way to see the cost is a direct comparison. Here’s what a £200,000 repayment mortgage with 20 years remaining looks like at different rates:

Rate	Type	Monthly payment	Annual cost	vs SVR saving
7.13%	Average SVR	£1,562	£18,744	Baseline
5.54%	Avg 5-year fix (July 2026)	£1,376	£16,512	£186/month saved
4.50%	Competitive 5-year fix (75% LTV)	£1,265	£15,180	£297/month saved
3.99%	Best buy 5-year fix (60% LTV)	£1,211	£14,532	£351/month saved

At the average SVR versus the average 5-year fix, the difference is £186 per month. Over five years, that’s £11,160 in unnecessary interest. Even after deducting a £1,000 arrangement fee and £300 in legal costs, remortgaging saves you over £9,800. The break-even point, where remortgaging costs pay for themselves, is typically two to four months.

When Should You Remortgage?

Start looking three to six months before your current deal expires. Most lenders let you lock in a new rate up to six months in advance. This protects you both ways: if rates rise before your deal ends, you’ve secured the lower rate. If rates fall, many lenders let you switch to a better product before completion at no extra cost.

The trigger points where remortgaging almost always saves money:

Your fixed deal is expiring. This is the most common reason. If you do nothing, you’ll land on the SVR and start overpaying immediately.

You’re already on the SVR. There’s no penalty for leaving the SVR. No early repayment charge. You can remortgage at any time, and every month you delay costs you the difference between your SVR and the best available rate.

Your property value has increased. If your home was worth £200,000 when you bought it and it’s now worth £260,000, your LTV has dropped. Lower LTV means access to better rate bands. This alone can save 0.3% to 0.5% off your rate.

Your income has changed. A promotion, new job, or second income can mean you now qualify for lenders or products that were previously out of reach. If you’ve recently started a new job, check lender criteria before applying.

When Does Staying on the SVR Actually Make Sense?

Almost never. But there are three genuine exceptions where the SVR can be the cheaper or smarter option.

You’re planning to sell within the next three to six months. If you remortgage onto a new 2 or 5-year fix and then sell before the fix ends, you’ll face an early repayment charge, typically 1% to 5% of the outstanding balance. On a £200,000 mortgage, that’s £2,000 to £10,000. The SVR carries no ERC, so if completion is imminent, the short-term SVR overpayment may be cheaper than the ERC you’d trigger by selling mid-fix. Do the maths for your specific timeline.

Your remaining mortgage balance is very small. If you owe £30,000 with three years left, the interest difference between 7% SVR and 4.5% fixed is roughly £62 per month. A remortgage arrangement fee of £999 takes 16 months to recoup. If the fee exceeds the saving over the remaining term, the SVR is cheaper.

You believe rates will fall significantly in the next six to twelve months. This is a gamble, not a strategy. But some borrowers deliberately sit on the SVR for two or three months to wait for a better fix, accepting the short-term overpayment as the price of timing. The risk: rates don’t fall, or they rise, and you’ve paid SVR rates for months with nothing to show for it. If you take this approach, set a hard deadline and commit to switching by that date regardless.

Product Transfer vs Remortgage: What Is the Difference?

When your deal expires, your current lender will usually offer you a “product transfer”, a new rate with them, without a full re-application. It’s fast, there’s no legal work, no valuation, and often no arrangement fee. Sounds ideal. The problem is that product transfer rates are frequently not the best available. Your lender knows that convenience and inertia are powerful forces, and they price accordingly.

A UK Finance report projects product transfers will grow by 13% in 2026, largely because homeowners don’t realise they could do better elsewhere. Always compare your lender’s product transfer offer against the wider market before accepting. A whole-of-market broker can do this comparison in minutes and tell you whether the product transfer is competitive or whether switching lender is worth the extra paperwork.

When the product transfer wins: your circumstances have changed in a way that makes a full remortgage harder (credit issues since your original application, reduced income, a switch to self-employment). A product transfer usually doesn’t require a new affordability assessment, so it can be the only viable route if your financial profile has weakened since you first took out the mortgage.

What Does Remortgaging Cost?

The headline costs to budget for when switching to a new lender:

Arrangement fee: £0 to £2,000. Some of the best rates carry a fee of £999 to £1,499. Fee-free products exist but typically at a slightly higher rate. On a large mortgage (£250,000+), paying the fee for a lower rate usually works out cheaper over the fix period. On a smaller balance, the fee-free option can be better. Your broker should model both.

Valuation fee: Often waived by the new lender as a switching incentive. If charged, typically £250 to £600.

Legal fees: Many remortgage products include free legals (paid by the lender). If not, budget £300 to £800.

Early repayment charge (ERC): Only applies if you’re leaving a current fix early. Typically 1% to 5% of the outstanding balance, declining each year. If your deal has already expired and you’re on the SVR, there’s no ERC.

Exit fee / deeds release fee: A small charge from your current lender to close the old mortgage, typically £50 to £300.

Total realistic cost for a straightforward remortgage with free legals and free valuation: £0 to £1,500. Total realistic saving over five years on a £200,000 mortgage: £9,000 to £18,000. The numbers aren’t close.

How to Remortgage Step by Step

Step 1: Check when your current deal expires. Look at your original mortgage offer or your lender’s online portal. Start the process three to six months before that date.

Step 2: Get your current property value estimated. Zoopla, Rightmove, or your lender’s valuation tool will give you a rough figure. This determines your LTV, which determines your rate.

Step 3: Compare the market. Don’t just accept your lender’s product transfer. Use a whole-of-market broker to compare rates from every available lender, including broker-exclusive products you won’t find on comparison sites.

Step 4: Apply. Your broker submits the application with the chosen lender. You’ll need proof of income (payslips or SA302s if self-employed), bank statements, ID, and proof of address.

Step 5: Valuation and legal work. The new lender values your property (often free) and a solicitor handles the legal transfer (also often free on remortgage products).

Step 6: Completion. Your new mortgage pays off the old one. The switch happens. Your new rate and monthly payment begin. Typical timeline from application to completion: four to eight weeks.

Can You Release Equity When You Remortgage?

Yes. If your property has increased in value or you’ve paid down a significant portion of your mortgage, you can borrow more than your remaining balance and take the difference as cash. This is commonly used for home improvements, helping a child with a deposit, debt consolidation, or funding a buy-to-let purchase.

Be cautious with debt consolidation. You’re converting short-term unsecured debt (credit cards, personal loans) into long-term debt secured against your home. The monthly payment drops because you’re spreading it over 20+ years, but the total interest paid is usually higher, and your home is now at risk if you can’t pay. A broker should model the total cost over the full term, not just the monthly payment.

For homeowners over 55, a lifetime mortgage (equity release) is a separate product designed specifically for accessing property wealth in retirement. Different rules, different structure, different advice requirement.

Frequently Asked Questions

What is a standard variable rate mortgage?
It’s the default rate your lender charges after your fixed, tracker, or discounted deal expires. Your lender sets it and can change it at any time. The average SVR in July 2026 is 7.13%, significantly higher than the best available fixed rates.

Is there a penalty for leaving the SVR?
No. The SVR carries no early repayment charge. You can leave at any time by remortgaging to a new deal with your current lender or a different one. The only cost is the small exit/deeds release fee, typically £50 to £300.

How much can I save by remortgaging off the SVR?
On a £200,000 mortgage, switching from the average SVR (7.13%) to the average 5-year fix (5.54%) saves roughly £186 per month, or £11,160 over five years. With a competitive rate at lower LTV, the saving can exceed £300 per month.

Should I accept my lender’s product transfer?
Maybe. Product transfers are quick, fee-free, and don’t require a new affordability assessment. But they’re not always the cheapest option. Always compare the product transfer rate against the wider market before accepting. A broker does this in minutes.

How long does remortgaging take?
Four to eight weeks from application to completion in most cases. Start three to six months before your deal expires to give yourself time and avoid landing on the SVR.

Can I remortgage if I’m self-employed?
Yes. Most lenders want one to two years of self-employed accounts (SA302s and tax year overviews). If your income has dropped since your original mortgage, a product transfer with your current lender might be easier because it often skips the affordability reassessment.

Can I remortgage with bad credit?
Yes, though your options narrow. Specialist lenders like Kensington, Aldermore, and Pepper Money consider remortgage applications with adverse credit history. A larger equity position (lower LTV) helps significantly. See our bad credit mortgage guide.

What happens if my property value has dropped?
Your LTV increases, which may push you into a higher rate band or limit your lender choice. In extreme cases (negative equity), remortgaging to a new lender may not be possible, and a product transfer with your current lender becomes the only option.

Can I overpay my mortgage instead of remortgaging?
Most lenders allow overpayments of up to 10% of the balance per year without penalty, even on a fix. Overpaying while on the SVR reduces your balance and your LTV, which can get you a better rate when you do remortgage. If you’re on the SVR temporarily, overpaying makes sense as a short-term strategy.

Is now a good time to remortgage in 2026?
If you’re on the SVR, yes, immediately. If your fix is expiring within six months, yes, lock in now. The Bank of England base rate has been reduced from its 5.25% peak and most forecasts suggest further cuts through 2026, but waiting on the SVR for rates to fall is a gamble that costs you hundreds per month while you wait.
