Bank of England raises rates to 4%: mortgage costs and a guide for buyers and owners

On 5 November, the Bank of England announced an increase in Bank Rate from 3.75% to 4%.

This is the Bank’s first rate rise since August 2023 and the first change in rates for almost a year.

A quarter of a percentage point may seem small, but it marks a shift in the conversation: from when rates might fall to whether they could rise again.

With the interest-rate outlook taking a sudden turn, what should overseas investors and families planning a property purchase focus on?

01 Why has the Bank raised rates?

The main driver is renewed inflationary pressure.

Inflation above expectations: UK CPI inflation rose to 3.5% in September, its highest level in almost 11 months and well above the Bank’s 2% target.

Higher imported costs: continuing tensions in the Middle East have pushed energy supply-chain costs back up, making them a major source of inflation.

A clear signal from the vote: the Monetary Policy Committee voted 8–1 for the increase. The sole dissenting member wanted a larger, half-percentage-point rise to 4.25%, rather than no change, underlining the Committee’s determination to tackle inflation.

02 How much could mortgage payments rise?

The effect on borrowers depends directly on the type of mortgage they hold.

1. Variable-rate borrowers: trackers and SVRs

Tracker mortgages will follow the quarter-percentage-point increase in Bank Rate. Standard variable rates are set by individual lenders and usually rise too. New payments generally take effect within a few weeks; check your lender’s notice for the precise timing.

For a capital-and-interest repayment mortgage, the estimated monthly increases are:

£100,000 mortgage: around £15 a month

£500,000 mortgage: around £75 a month

£1 million mortgage: around £150 a month

For interest-only mortgages, the increase is slightly higher, at around £21 a month for each £100,000 borrowed.

These are estimates. Actual payments depend on the outstanding balance, remaining term and lender pricing.

2. Fixed-rate borrowers

Still within your fixed-rate period: this increase does not affect your payments, which remain as agreed until the deal ends.

Approaching the end of a deal or applying for a new mortgage: expectations of higher rates have already fed into some mainstream lenders’ pricing, with some lower-rate products withdrawn. Buyers who have not secured a rate should watch for further changes to lenders’ product ranges.

SJW’s perspective

Overseas buyers arranging a mortgage or preparing to enter the market should reassess borrowing costs and monthly affordability using a base-rate scenario above 4%, with a cash-flow buffer as a priority.

03 Could the Bank raise rates again?

The Bank’s latest forecast suggests inflation could approach 5% by mid-2027, reflecting uncertainty over energy and supply chains.

Governor Andrew Bailey has indicated that further rises remain possible if geopolitical conflict continues to put pressure on inflation. He has also emphasised that this decision should not be interpreted simply as the start of a prolonged series of frequent rate increases.

Market expectations: the median response to the Bank’s Market Participants Survey points to rates moving towards 4.25% in the first quarter of 2027. The path remains highly dependent on incoming data.

The next interest-rate decision is due on 17 December 2026.

What should overseas landlords and buyers do now?

For overseas landlords, reliable rental income becomes even more important as mortgage payments rise. SJW Property Management’s established approach is to discuss renewals with tenants before their tenancy ends, reducing void periods, and to screen tenants carefully before they move in, reducing the risk of arrears. These day-to-day tasks matter even more when rates are rising.

For buyers, the impact differs according to how you plan to fund the purchase.

Cash buyers are unaffected by higher mortgage rates. As some borrowers slow their plans because of higher monthly payments, cash buyers often have a stronger negotiating position.

Mortgage buyers should aim to secure a formal mortgage offer early. The offered rate can usually be held for a period, reducing uncertainty if rates rise again at the next meeting.

New-build buyers can pay a deposit to secure the price and apply for a mortgage closer to completion, then consider a fixed or variable rate in light of the market at that point.
