Fixed mortgage rates are falling in May 2026. Here is what buyers and remortgagers across Huntingdonshire should do before 18 June.

What the lenders have done in May.

Three weeks into May, the picture for anyone tracking mortgage rates looks markedly different from a month ago. Nationwide, the country's second-largest mortgage lender, cut its fixed rates by up to 36 basis points on 12 May, bringing its lowest available two-year fix to 4.35%. HSBC reduced rates by up to 30 basis points in the week ending 8 May. Halifax, Santander, Virgin Money and NatWest each followed with their own reductions across two-year and five-year fixed products.

Crucially, the deepest cuts have gone to higher loan-to-value products. At 95% LTV (a 5% deposit), Nationwide applied some of its steepest reductions, which matters directly for first-time buyers in Huntingdon, Brampton and across the patch who are buying with smaller deposits.

This is not a Bank Rate cut. The Bank of England held at 3.75% on 30 April and is not expected to move on 18 June. These are lender-level pricing decisions, driven by swap-rate movements, not by any change in the base rate.

Why rates are moving independently of the Bank Rate.

Fixed mortgage rates in the UK are priced off swap rates (the rates at which banks lend to each other over fixed periods) rather than directly off the Bank Rate. When swap rates rise, fixed mortgage rates tend to follow. When swap rates ease, lenders can pass on cheaper wholesale funding to borrowers.

In late March 2026, swap rates jumped sharply as energy-market uncertainty intensified. Average fixed rates moved noticeably higher in response. By early May, some of that pressure had unwound, and lenders repriced downward. With spring transaction volumes picking up and lenders competing for purchase and remortgage business ahead of summer, the incentive to attract new borrowers is strong.

For buyers and sellers across Godmanchester, St Ives and the surrounding patch villages, where the majority of buyers take two or five-year fixed products, this window matters in practical terms. A 36-basis-point reduction on a typical Huntingdonshire property price of around £308,000 over a two-year fix translates to a meaningful monthly saving.

The risk: swap rates are not staying put.

Since the early-May repricing wave, swap rates have edged back up. Mortgage analysts tracked by Moneyfacts have cautioned that the current round of lender cuts could slow or reverse rather than build into a sustained downtrend. The 4.35% headline rate available from Nationwide today may not represent the floor, and there is no guarantee that other lenders will not follow if their cost of funds rises.

The Bank of England's April MPC statement noted that the committee would act if inflation proved more persistent than expected, with energy prices the key wildcard. CPI stood at 2.8% in April, down from 3.3% in March, but the direction through the summer is not settled. If inflation accelerates again, the Bank Rate could come under upward pressure, and the June or August MPC decision could shift the swap-rate expectations that underpin fixed pricing across all lenders.

That creates a practical situation for buyers and remortgagers: the cheapest window of 2026 so far may already be open, but there is no certainty it stays open into the summer or autumn.

What to do if you're buying or remortgaging across the patch.

For buyers with an offer accepted on a home in Huntingdon, Brampton, Godmanchester, St Ives or any of the 56 patch villages: most lenders will let you reserve a fixed rate up to six months before completion. That means you can lock in May's pricing without needing to have exchanged contracts yet.

For remortgagers whose current deal expires in the next six months: the same logic applies. You can often instruct a rate reservation well ahead of your existing deal ending, and many lenders will move you to a better product if rates fall further before your completion date.

For buyers still looking for a property across the patch: the 18 June MPC decision is unlikely to change rates in itself, as no cut is expected. But swap-rate movements in the days around a decision can shift lender pricing quickly. If you are close to making an offer, speaking to an independent estate agent in Huntingdon about timing your purchase is worth doing before the market moves for you.

First-time buyers in the patch with a 5% or 10% deposit have the most to gain from the current repricing. The biggest cuts in May went to higher-LTV products precisely because lenders want first-time-buyer business. If you have been waiting for rates to fall before applying, the May cuts give a concrete reason to revisit your affordability calculations this week, according to Bank of England data on the current rate environment.
