Data from Moneyfactscompare.co.uk indicates that UK mortgage products remained available for an average of 13 days in September 2026 before being withdrawn by lenders. This figure contributes to an annual average of 15 days for 2026, which is on track to be the shortest duration since digital record-keeping began.
The reduction in product availability follows a period of economic volatility linked to the conflict in the Middle East. Lenders have adjusted or removed fixed-rate mortgage deals in response to fluctuations in swap rates—the rates at which banks lend to each other—which have been affected by oil price changes and shifting news regarding the conflict.
According to Moneyfacts, mortgage volatility peaked in April 2026, immediately following the outbreak of the conflict, when the average shelf life for a deal dropped to eight days. Between May and October 1, the average shelf life stabilized at approximately 13.8 days. As of October 19, 2026, the average five-year fixed residential mortgage rate stands at 5.99 percent, down slightly from a recent peak above 6 percent.
The scale of this shift is reflected in the increased costs for households. With the average five-year fixed rate at 5.99 percent, borrowers transitioning from older, lower-rate deals will see a direct increase in their monthly housing expenditures. Adam French of Moneyfacts noted that lenders are withdrawing deals to manage the cost of funding as swap rates fluctuate.
The knock-on effects include increased pressure on mortgage brokers and estate agents as they attempt to lock in deals for clients in a volatile environment. Ian Harris, president of Propertymark, stated that the current market creates added pressure for both borrowers and brokers to act quickly. While homeowners can often select a new product up to six months before their current deal ends, the shortened availability period increases the risk of missing market windows. Borrowers are currently advised to seek advice early, as further escalations or reconciliations in the Middle East conflict are expected to continue influencing funding costs through the end of 2026.
