Should I Remortgage My Buy to Let in 2026?

If your current BTL deal is ending or you are already on your lender SVR, you are likely paying more than you need to. Here is how to assess whether remortgaging makes sense in 2026.

What is happening with BTL mortgage rates right now?

The Bank of England base rate has been falling since late 2024. Buy to let mortgage rates have responded, with five-year fixed deals now available from around 4.2-5.0% depending on LTV and rental coverage.

For landlords who fixed in 2020 or 2021 at sub-2% rates, rates are still higher than they were. But waiting on an SVR (typically 7-9%) while doing nothing is expensive.

Does remortgaging make financial sense?

A 250,000 BTL mortgage at 8% SVR costs approximately 1,667 per month on interest-only. The same mortgage at 4.5% fixed would cost approximately 938 per month - a saving of around 729 per month, or 8,748 per year.

Even accounting for early repayment charges and arrangement fees, the numbers typically justify switching in most cases.

Should you fix for 2 or 5 years?

A 2-year fix offers a lower initial rate and more flexibility if rates fall further. A 5-year fix offers payment certainty and fewer arrangement fees over the period.

For long-term investors with no plans to sell, the 5-year fix often offers better total value. If you anticipate significant rate falls, a 2-year deal keeps options open.

Frequently asked questions

When should I start looking at BTL remortgage rates?
Start looking 3-6 months before your current deal expires to avoid rolling onto SVR. If you have a portfolio, we can stagger review dates to manage cashflow.
Can portfolio landlords remortgage?
Yes. With 4 or more mortgaged buy to let properties you are classified as a portfolio landlord. Lenders assess your whole portfolio. We specialise in portfolio landlord cases.
Can I remortgage a BTL into a limited company?
Yes, though it involves stamp duty, legal costs, and potentially CGT as it is a new purchase by your company. We advise on whether the numbers stack up for your situation.
