Mortgage deals last 13 days, leaving borrowers less time to compare

What happened

Mortgage deals remained available for an average of 13 days in October, according to the Moneyfacts UK Mortgage Trends Treasury Report, reported on 19 October 2026. That compares with 14 days in September. For buyers and homeowners looking to remortgage, the figures describe a market in which a product seen during an initial search may have changed before they apply.

Moneyfacts puts the average product shelf-life for 2026 so far at 16 days, against 20 days in 2025. Its figures show that availability has shortened substantially over a longer period: the annual average was 43 days in 2019 and 34 days in 2020. The 2026 figure is a year-to-date measure, rather than a completed annual result.

October was not the most disrupted month in the series. According to Moneyfacts, the average fell to a record eight days in April, following the initial impact of the US-Iran conflict. The latest reading therefore shows products remaining available longer than at that low point, despite the shorter window compared with September.

Moneyfacts said fluctuations in swap rates had prompted lenders to change prices repeatedly or remove products. Its head of consumer finance, Adam French, linked those movements to uncertainty surrounding the war in the Middle East. These figures concern how long mortgage products stay on the market; they do not measure the time lenders take to assess an application or complete a property purchase.

The background

Swap rates are one influence on the funding costs behind fixed-rate mortgages. They reflect financial markets’ expectations about interest rates, among other factors, and can move before any change in the Bank of England’s base rate. French said reports of possible reconciliation or renewed escalation in the Middle East had affected swaps and, in turn, the cost of funding fixed-rate lending.

A product’s shelf-life is different from the length of its fixed-rate period. A mortgage advertised with a rate fixed for several years can be removed from sale much sooner without shortening that fixed period for an existing borrower. The Moneyfacts average is also not a deadline attached to every product: it cannot tell an applicant exactly when a particular lender will change a deal.

Product availability is separate from the validity of an individual mortgage offer. An agreement in principle, a full application and a formal offer are different stages, and borrowers should check with the lender or broker when their chosen rate is secured. A deal disappearing from general sale does not, by itself, establish what happens to an application already under way.

The advertised interest rate is only one part of a mortgage comparison. Product fees, the loan size, repayment term and any early repayment charges can affect which option fits a household’s circumstances. That wider calculation is particularly relevant to first-time buyers comparing mortgage payments with rent, because a low headline rate does not necessarily mean the lowest overall borrowing cost.

What people are saying

French’s central concern is the combination of rate movements and limited product availability, rather than either issue alone. He said brokers and consumers were having to navigate changes in both the price of borrowing and the choice of deals. In his assessment, that makes it harder for borrowers to reach a decision with confidence, even after they have compared the available options.

He distinguished the sustained disruption in 2026 from earlier episodes, including the Covid pandemic in 2020 and the mini-Budget in 2022. Those events caused substantial short-term disturbance, he said, but the prolonged instability this year was different. The annual shelf-life figures supplied by Moneyfacts give some context to that assessment, although they do not show every movement within each year.

French said changing funding costs left lenders needing to reprice mortgages or withdraw them. He also highlighted brokers’ work helping customers deal with the rapid changes. His account describes a market-wide funding problem, rather than a difficulty confined to one lender, but the reported figures do not identify which providers changed their ranges most frequently or which borrowers faced the greatest disruption.

For consumers, French described two risks: a suitable deal could disappear before they were ready to proceed, while waiting could mean returning to a different rate. He said borrowers should not blame themselves if the market subsequently moved against them. His comments did not amount to a forecast that rates would move in one direction; they stressed how difficult global uncertainty makes the timing of a decision.

What happens next

For someone currently comparing mortgages, the practical starting point is to confirm that an advertised product is still available before relying on its payment figures. A lender or broker can explain what is needed to apply and at which stage the rate is secured. Being ready to supply documents can help with the application process, but the Moneyfacts figures offer no guarantee that any particular deal will remain open.

Homeowners approaching the end of a fixed-rate period can check their current deal’s expiry date, outstanding balance and any early repayment charges before comparing replacements. They should also establish the terms of any new offer, including its validity period. Those checks separate the household’s own timetable from market speculation: a short product shelf-life is not, on its own, a reason to accept an unsuitable mortgage.

Buyers can keep their borrowing budget separate from the asking price of a home. A lower purchase price and a changed mortgage rate affect affordability in different ways, as explored in family-home affordability and mortgage costs. The same distinction matters when considering Rightmove’s October asking-price picture: a property-price comparison cannot replace an up-to-date borrowing illustration.

Future Moneyfacts readings will provide a clearer picture of whether October’s shorter availability persists and how the full-year average compares with earlier years. The current data do not establish where mortgage rates will go next, or how long an individual product will stay available. Borrowers can use the figures as evidence that comparisons may need refreshing, rather than as a timetable for predicting the cheapest day to apply.

Why this matters

Moneyfacts’ figures show why buyers and remortgaging homeowners may need to refresh mortgage comparisons while making decisions. A payment estimate based on an earlier search may no longer reflect the products available when they apply. The practical distinction is between preparing promptly and rushing into a commitment: borrowers still need to assess fees, affordability and mortgage terms. The 13-day average signals changing availability, not a deadline for every applicant or a prediction of where rates will go.
