Interest Rates Are Rising. Is Your Rental Income Protected?

With the Bank of England raising interest rates to 4%, landlords face renewed pressure on borrowing costs and rental profitability. Could guaranteed rent offer greater certainty?

The Bank of England has increased its base rate from 3.75% to 4% on 5 November 2026, marking the first interest rate rise in more than three years.

For landlords already managing rising maintenance, compliance and property management costs, the announcement brings another financial consideration.

While rental income may remain consistent, the cost of maintaining a property investment can continue to rise. And when margins are already tight, even a short void period or unexpected expense can have a significant impact.

What Does the Interest Rate Rise Mean for Landlords?

The impact will depend largely on the type of mortgage a landlord holds.

For those on tracker mortgages, the increase in Bank Rate will generally be reflected in higher monthly repayments. Landlords on variable-rate products may also see their borrowing costs increase, depending on their lender.

Those on fixed-rate mortgages are protected from immediate changes to their mortgage payments, but may face higher costs when their current deal expires.

According to UK Finance, approximately 2.3 million fixed-rate mortgage deals are due to expire during 2027, highlighting the number of borrowers potentially exposed to changing refinancing conditions.

For landlords, this makes reviewing the long-term profitability of their rental properties increasingly important.

Rising Costs, Tighter Margins

Mortgage repayments are only one part of the equation.

Landlords must also account for maintenance, insurance, compliance requirements, property management fees and the possibility of rental voids.

When these expenses increase, the difference between gross rental income and actual take-home income can narrow considerably.

Consider a property generating £2,000 per month in rent. A single month without a tenant represents £2,000 in lost gross income, before accounting for any additional costs associated with finding a replacement occupant.

Combined with higher borrowing costs, even relatively short periods without rental income can place additional pressure on annual returns.

This raises an important question: is achieving the highest advertised rent always the same as achieving the best financial outcome?

Why Income Certainty Matters

In a changing economic environment, predictable rental income can become particularly valuable.

While landlords cannot control interest rate decisions, they can consider arrangements that reduce their exposure to certain risks associated with traditional lettings.

Guaranteed rent agreements offer an alternative approach, providing a fixed, agreed rental income over a contractual period, regardless of whether the property is occupied.

For landlords, this can mean greater predictability when budgeting for mortgage payments, planning property expenditure and assessing long-term investment returns.

Although the agreed rent may differ from the potential open-market rental value, the reduction in void exposure and management costs can make the overall financial picture worth considering.

How Apex Guaranteed Rent Can Help

At Apex Housing Solutions, our guaranteed rent model is designed to provide landlords with greater financial certainty and reduce the day-to-day responsibilities of managing a rental property.

Our agreements offer:

• Fixed monthly rental income throughout the agreed term.

• No rental void losses for landlords during the agreement.

• Free property and utility management, reducing administrative responsibilities.

• Ongoing property management support, including compliance monitoring and coordination of maintenance.

By combining predictable income with ongoing management, landlords can focus on the longer-term performance of their investments rather than fluctuations in occupancy.

Looking Beyond the Headline Rent

The latest interest rate increase is another reminder that rental profitability depends on more than the amount of rent advertised each month.

Borrowing costs, void periods, maintenance and management expenses all influence what landlords ultimately retain.

As the property market continues to evolve, reviewing how rental income is structured may be just as important as reviewing the mortgage itself.

At Apex, we believe that certainty, consistency and reduced management responsibilities can provide meaningful value for landlords navigating an increasingly challenging market.

You can't control interest rates. But you can take steps to make your rental income more predictable.
