The Treasury has asked Britain’s biggest lenders to step up direct help for borrowers whose fixed-rate mortgages expire this year. Following a meeting on 26 March 2026, banks and building societies agreed to proactively contact around 1.6 million customers ahead of any payment change, laying out options and routes to tailored support. The Mortgage Charter was also reaffirmed. (gov.uk)

For households, the message is simple: expect earlier, clearer communication. Lenders will outline eligibility for support before higher repayments bite, and confirm what can be done without denting a customer’s credit file. HM Treasury says most UK mortgages remain on fixed rates, so short-term market swings should not hit the majority immediately. (gov.uk)

A key practical point is rate‑switching with your existing lender, often called a product transfer. Under the Mortgage Charter, customers up to date with payments can switch to a new deal with their current lender without a fresh affordability check, provided they are not borrowing more or changing their repayment type or term. This applies to regulated residential mortgages, not buy‑to‑let. (gov.uk)

Timing also improves. Customers can book a new rate up to six months before their fix ends, then request a better like‑for‑like deal if rates fall before the new term starts. This combination - early lock‑in plus the ability to re‑price later - helps households manage rate risk without repeated applications or credit searches. (gov.uk)

Temporary breathing space remains available. Borrowers current on payments can move to interest‑only for six months or extend their mortgage term, with the option to revert within six months. Taking up these measures and talking to a lender does not affect credit files, though overall borrowing costs may be higher over the life of the loan. (gov.uk)

What could that look like in pounds and pence? On a £200,000 balance at 5% with 25 years remaining, a full repayment would be roughly £1,170 a month. Switching to interest‑only for six months would drop payments to about £833 - a temporary saving near £340 a month. This is illustrative, not advice, and interest continues to accrue during the pause.

There’s encouraging backdrop data. UK Finance reports that homeowner arrears accounted for 0.92% of all homeowner mortgages outstanding in Q4 2025, with buy‑to‑let arrears at 0.50%. That suggests stress remains contained in aggregate even as individual households face higher refinancing costs. (ukfinance.org.uk)

Policy context matters for planning. The Government’s update highlights that around 86% of UK mortgages are on fixed rates, insulating most borrowers from immediate market volatility. But for the 1.6 million rolling off this year, early engagement and use of the Charter’s six‑month window are the best defences against payment shocks. (gov.uk)

If your deal ends in the next six months, check your lender has up‑to‑date contact details, review the retention products on offer, and ask explicitly about like‑for‑like re‑pricing. If your income has changed, or you’re near retirement, speak to the lender sooner - permanent switches to interest‑only or extending beyond expected retirement may still need affordability checks. Conversations and short‑term Charter options won’t hit your credit file. (gov.uk)

This is a nudge, not a bailout. The Charter makes switching simpler with the same lender, buys time through short‑term interest‑only or term tweaks, and gives borrowers a six‑month runway to shop around in calmer conditions. When your bank gets in touch, respond early - small decisions made now can prevent large bills later. (gov.uk)
