The UK mortgage market in 2026 is being driven by forces few predicted at the start of the year. Here's our detailed forecast of where rates are heading — month by month — and what it means for your mortgage. Updated April 2026

Mortgage Rate Forecast: Month by Month

These are forecasts based on current market expectations. Actual rates will depend heavily on geopolitical developments, UK inflation data, and Bank of England decisions. Forecasts are subject to significant uncertainty.

The Swap Rate Connection

Fixed mortgage rates are primarily priced off swap rates — financial contracts between banks that reflect where interest rates are expected to go. When the Middle East conflict erupted, swap rates jumped sharply as markets repriced inflation and interest rate expectations. Lenders immediately passed these higher costs onto borrowers through higher mortgage rates.

For rates to fall significantly, swap rates need to fall — which requires either the Middle East situation to de-escalate, UK inflation to fall sharply, or the Bank of England to signal rate cuts are coming.

The 1.8 Million Remortgaging Opportunity

UK Finance estimates 1.8 million fixed-rate mortgages expire in 2026. Many of these borrowers locked in at 1-2% rates in 2021-22. The reality is painful: someone remortgaging a £250,000 loan from 1.5% to 5.5% faces an extra £900/month in payments. The sooner they act, the sooner they lock in certainty rather than floating on an SVR at 7-8%.
