Many UK borrowers who bought or remortgaged during the post-pandemic property boom are now approaching the end of five-year fixed-rate deals. The practical issue is simple: if no new deal is arranged, the mortgage normally moves onto the lender’s standard variable rate (SVR), which can be more expensive and can change at short notice. Start reviewing options several months before the deal ends, comparing a product transfer with a full remortgage and checking any early repayment charge.

Why five-year deals are now a remortgage issue

The post-pandemic housing market encouraged many borrowers to lock into five-year fixed-rate mortgages. Those deals gave payment certainty during the initial period, but they do not last for the whole mortgage term. When the deal period ends, the borrower usually either chooses a new product with the same lender, remortgages to another lender, or falls onto the SVR.

MoneyHelper explains that remortgaging is commonly used when an existing mortgage deal is ending, but borrowers should weigh fees, legal work, valuation, affordability checks, and any early repayment charge before switching (MoneyHelper, 2026).

That is why the current remortgage market is being shaped by decisions made during the boom years. A large group of homeowners fixed at the same time, so a large group now has to decide whether to refix, track the Bank of England base rate, move to a discount deal, stay variable for flexibility, or accept a product transfer.

What changes when the deal ends

A fixed-rate deal protects the monthly payment during the initial period only. After that, the lender’s reversion rate normally applies unless the borrower switches. This matters because the SVR is not the same as the Bank of England base rate. The base rate influences mortgage pricing, especially tracker and variable products, but each lender sets its own SVR and product margins. The Bank of England describes Bank Rate as the core interest rate in the UK and says it affects the lending and savings rates set by banks and building societies (Bank of England, 2026).

As of July 2026, mortgage rates and lender criteria change frequently, so verify current terms with an FCA-authorised lender or adviser before deciding.

Product transfer or full remortgage?

A product transfer means taking a new deal with the same lender. It can be quicker because the lender already has the mortgage, and it may involve less paperwork. A full remortgage means moving to a new lender. That can give access to a wider market, but it may involve affordability checks, conveyancing, a valuation, arrangement fees, and more administration.

Which? notes that mortgage choices include guides on mortgage types and calculators for repayments, LTV and the base rate, which is a useful reminder that the cheapest-looking headline rate is only one part of the decision (Which?, 2026). For a borrower coming off a five-year fix, compare the APRC, product fee, valuation fee, legal costs, ERC, overpayment rules, portability, and what happens after the new deal period ends.

MoneySavingExpert also highlights mortgages as an area where borrowers should compare costs carefully, because the wider deal structure can matter as much as the advertised rate (MoneySavingExpert, 2026).

What to do before your fixed rate ends

Check your mortgage offer or annual statement for the end date, outstanding balance, current loan-to-value (LTV), ERC period, and remaining term. Then ask your current lender what product transfer options are available, and compare those with whole-of-market remortgage options.

If your home has risen in value since the post-pandemic boom, your LTV may have improved, which can sometimes help pricing. If affordability has tightened, your income has changed, or you have taken on new credit, a product transfer may be simpler than moving lender, but it still needs careful comparison.

Avoid waiting until the last week. Remortgages can take time, especially if legal work or valuation queries are involved. Many borrowers begin reviewing options around six months before the deal ends, then decide closer to completion if rates, fees, and criteria still make sense.

Bottom line

The UK remortgage market is busy because many five-year fixes taken during the post-pandemic property boom are now reaching maturity. The main risk is drifting onto SVR without checking alternatives. Compare a product transfer with a full remortgage, include all fees, and look at flexibility as well as rate.
