The BoE Held Rates at 3.75%. Your Remortgage Math Just Changed

The Bank of England held Bank Rate at 3.75% on 30 July 2026, giving landlords a stable base to plan the next remortgage rather than wait for a cut that may not arrive. The overlooked move is to re-run ICR affordability and monthly payments now, then compare a 2-year fix with a 5-year fix, because longer fixes often use a lower stress rate and can raise your maximum loan on the same rent.

This briefing is for UK landlords and portfolio investors whose buy-to-let deal is ending, or who are sizing a remortgage while Bank Rate sits at 3.75%. You will see why a hold can be an opportunity, how to use a buy to let mortgage calculator for ICR and payments, and why switching product term can change borrowing power more than waiting for the next MPC headline.

What the 3.75% hold really means for landlords

A Bank Rate hold is planning certainty, not a promise that your mortgage price stays frozen. On 30 July 2026 the MPC kept Bank Rate at 3.75%, with a split vote that still leaves room for later rises. For landlords, the useful response is to model today's remortgage, not to pause every decision until September.

Fixed buy-to-let rates track swap markets and lender appetite as much as Bank Rate. That is why the productive question after a hold is: what max loan and monthly payment do I get on my current rent if I act now?

Step 1: remortgage with ICR and payment certainty

Start with PRA-style affordability, then check the monthly payment you can actually live with. Enter monthly rent, borrower type (individual or limited company), tax band where relevant, and a realistic product rate. The buy to let mortgage calculator applies Interest Coverage Ratio stress testing so you see maximum loan before you fall in love with a headline rate.

Next, open the payments tab and compare interest-only with capital-and-interest on the same loan amount. Interest-only can free cash flow for portfolio growth; repayment builds equity faster. Either way, you leave the hold with a plan instead of a guess.

Step 2: the 5-year fix that can raise your max loan

Here is the remortgage math many landlords miss after a rate hold: product length can change borrowing power more than waiting for a 0.25pp cut. On the affordability calculator, toggle between a 2-year fixed and a 5-year fixed. Lendlord's tool notes that 5-year fixes often use a lower stress rate, which can increase the maximum loan on identical rental income.

That does not mean every landlord should take five years. It means you should quantify the trade-off: more borrowing capacity and longer rate certainty versus less frequent remortgage flexibility. Run both terms, then compare monthly payments on the loan size each term actually supports.

Worked example: same rent, different product term

Keep the rent fixed and only change product term so the lesson is clean. Imagine a limited-company single let with £1,500 monthly rent. First calculate maximum loan on a 2-year fix at a current market rate. Then switch to a 5-year fix and recalculate. If the stress rate falls, max loan often rises even though Bank Rate did not move.

Finally, drop each max-loan figure into the payments calculator. You will see whether the higher loan still produces acceptable monthly cash flow on interest-only or repayment. That is the positive remortgage play after a hold: certainty to plan, plus a term switch that can unlock capacity.

When to stop calculating and talk to a lender panel

The calculator is for illustration; live products decide the real outcome. Once you know the loan size and payment band that work, compare live buy-to-let options across lenders and submit a remortgage enquiry with clean figures. Portfolio landlords should also watch expiry concentration so several deals do not hit the reversion rate in the same quarter.
