The Bank’s announcement and minutes explain why the distinction matters. Six members voted to hold, while three wanted an increase to 4%. The minutes also describe higher market interest rates feeding through into the borrowing costs faced by households and businesses.
They report that quoted two-year fixed mortgage rates were around 0.95 percentage points above their level before the Middle East conflict. That is a general mortgage-market observation, rather than a figure specifically measuring buy-to-let loans, but it illustrates how lending rates can move even when Bank Rate is held.
The date your fixed rate ends matters to your business. An existing fixed rate normally continues for its agreed term. When that term expires, the deal available to replace it may be more expensive than the one arranged several years earlier, regardless of whether the Bank changed rates at its latest meeting.
As the Bank’s own explanation makes clear, Bank Rate is one influence on borrowing costs, and lenders’ rates can change for other reasons. For an owner planning the next few years, the useful exercise is to obtain figures for their own borrowing and see what the business can support.
I would start with a schedule showing each mortgage balance, the rate being paid, when the deal ends and what happens if no replacement is arranged. Alongside that, I would put the rent, realistic running costs and the cash reserve available for repairs and periods without rent.
A one percentage point change can take a substantial share of the income. Consider an illustrative portfolio with £1 million of interest-only borrowing, £90,000 of annual gross rent and a £25,000 allowance for operating costs and voids. That leaves £65,000 before mortgage interest and tax.
| Assumed interest rate | Annual interest | Cashflow before tax |
|---|---|---|
| 4% | £40,000 | £25,000 |
| 5% | £50,000 | £15,000 |
| 6% | £60,000 | £5,000 |
These rates are assumptions for comparison, not current mortgage quotations or forecasts. The figures hold rent, debt and the operating allowance constant, exclude refinancing fees, capital repayments and major capital expenditure, and show a full year at each assumed rate.
Moving from 4% to 5% adds £10,000 to annual interest and reduces the illustrated cashflow by 40%. The properties have not changed, yet the money available before tax is very different. In a real portfolio, the effect would arrive according to the individual loan terms and refinancing dates.
My published case study of a £3.4 million portfolio explores this in more detail. Under its stated assumptions, applying a 6% borrowing cost reduced estimated annual cashflow before tax from about £83,455 to £16,515. That was a sensitivity exercise, and the individual properties responded very differently.
Give yourself time to compare the options. A review well before a deal expires gives you time to obtain mortgage quotations, check the lender’s requirements and consider how the available terms fit your plans. Compare the total cost over the period you expect to keep the loan, including product fees and any early repayment charges.
There are practical trade-offs to work through. Repaying some borrowing could reduce interest costs, but would also use cash that might otherwise cover repairs or a prolonged vacancy. A longer commitment might provide more payment certainty while limiting the flexibility an owner wants for retirement or a planned sale.
I would also test the timing of those decisions. If several loans expire close together, or a major repair coincides with refinancing, an annual portfolio total may conceal a difficult few months. A monthly cashflow forecast can show when the money is needed and whether the reserve is sufficient.
The comparison should reflect what the owner wants from the business: dependable income, less debt, fewer management responsibilities or the ability to pass it on. Tax, transaction costs and the terms of any proposed finance then need to be worked through with the appropriate advisers before a decision is made.
You can make that assessment without predicting the next rate decision. Start with the terms actually available to you, then examine a less favourable scenario and an improvement. If the business can support your plans across that range, you have a clearer basis for deciding how to proceed.
If you would like help assembling that picture, a Property118 consultation can help you identify the information and commercial options to examine. You remain in charge of the decisions, with a mortgage adviser assessing suitable borrowing and the relevant professionals addressing the legal and tax implications.
