Mortgage Rate Outlook 2025 — What Borrowers and Buyers Need to Know

Where Mortgage Rates Stand in 2025

The Bank of England base rate peaked at 5.25% in August 2023, remaining at that level until August 2024 when the Monetary Policy Committee (MPC) made its first cut in four years, bringing the rate to 5.0%. Further cuts followed through late 2024 and into 2025, with the market pricing in a gradual path lower towards 3.5–4.0% through 2025–26.

For borrowers, this is welcome news after the sharp affordability squeeze caused by the rapid rate rises of 2022–23. But the relationship between base rate and mortgage rates is not as straightforward as many assume.

Base Rate and Mortgage Rates: The Distinction That Matters

The Bank of England base rate directly affects variable rate products — standard variable rates (SVRs) and tracker mortgages move in line with it. However, fixed-rate mortgages — which the majority of UK borrowers use — are priced against **swap rates**, which reflect market expectations of where interest rates will be over the fixed term.

Swap rates can move independently of base rate. If markets believe base rate will fall faster than the MPC signals, swap rates can fall ahead of actual base rate cuts, pulling fixed-rate mortgage pricing lower. If inflation re-accelerates or the MPC sounds hawkish, swap rates can rise even as base rate is unchanged.

This means fixed-rate mortgage pricing sometimes improves before base rate falls, and can worsen despite base rate stability.

The Fixed vs Tracker Dilemma in a Falling Rate Environment

When rates are falling, tracker mortgages appear attractive: your rate falls automatically with base rate, and you benefit from each MPC cut without needing to remortgage. However, this comes with risk: if rates reverse, your payments rise immediately.

Fixed rates offer certainty but mean you may miss further cuts. In a falling rate environment, shorter fixed terms (two years) offer a middle ground — you lock in current rates but can refinance sooner to benefit from lower rates if the forecast materialises.

The right choice depends on your circumstances: how much payment certainty you need, your loan-to-value ratio, whether early repayment charges matter, and your view on the rate trajectory.

What This Means for Buyers

Falling mortgage rates improve affordability directly. A buyer borrowing £250,000 over 25 years at 5.5% pays roughly £1,530 per month. At 4.5%, that falls to approximately £1,390 — a saving of around £1,680 per year.

Improved affordability typically supports house prices: more buyers can borrow more, competing for the same stock. If rates fall materially through 2025–26, demand is likely to strengthen, particularly in the sub-£500,000 segment.

More products are becoming available as lender competition returns. Loan-to-value ratios above 90% are more accessible than during the 2022–23 stress period, which benefits first-time buyers with smaller deposits.

What This Means for Remortgagers

Those coming off two-year fixed deals taken out at the peak of the market in 2022–23 (when rates were 5–6%) may find only marginal improvement when they remortgage in 2024–25. The saving versus their existing rate will depend heavily on when exactly they fixed and at what rate.

Borrowers who took five-year fixes in 2019–20 — when rates were at historic lows of 1.5–2.5% — face a larger shock when they reach the end of their term. Even if rates have fallen to 4–4.5% by the time they remortgage, the payment increase will be significant.

Starting a remortgage comparison 3–6 months before your current deal ends is advisable. Most lenders allow you to lock in an offer 3–6 months ahead, with the option to switch to a better product if rates improve before you draw down.

Using Property Passport UK Data in the Current Market

When buying in a market where affordability is improving but uncertainty remains, sold price data is a critical anchor. Property Passport UK aggregates HM Land Registry sold price records, allowing you to compare what similar properties in the same street or postcode have actually achieved — not just what they were listed for. In a market where affordability changes week to week, understanding real transacted values helps you bid with confidence.
