Buy To Let Remortgage UK Mortgage Guide # Buy To Let Remortgage UK 2026: Rates, ICR & Refinance Gap Remortgaging a UK buy-to-let in 2026 is harder than residential refinancing — the ICR stress test gets in the way.

Rent £900/month. - 2021 ICR test (5.5% stress, 145%): required rent = £150k × 5.5% ÷ 12 × 145% = £997. Just passed (or lender accepted a top-slice). - 2026 ICR test (7% stress, 145%): required rent = £150k × 7% ÷ 12 × 145% = £1,269. Current rent of £900 = £369 short. - Max loan supportable at £900 rent: £900 × 12 ÷ 7% ÷ 1.45 = £106,400. - Landlord must inject £43,600 capital, raise the rent, or move to a 5-year fix at lower stress (5.5%) where max loan rises to £135,400. ## Capital raising on BTL remortgage Remortgages · keep reading - [Remortgage to buy another property Release equity from your home to fund a second purchase. ](/remortgage-to-buy-another-property) - [Best time to remortgage When to apply, lock and complete to avoid SVR exposure. ](/best-time-to-remortgage) Browse the full hub: [Remortgages](/remortgages) Want a vetted broker to help with Capital raising on BTL remortgage?

[Match me with a broker](/find-a-mortgage-broker) Some landlords use remortgage timing to transfer property into an SPV. Tax consequences: - CGT triggered on the personal sale to the company at market value. - SDLT triggered on the company purchase (including 5% surcharge). - Incorporation Relief may defer CGT if you meet strict criteria (must be a 'business' for tax purposes). Get accountant advice before incorporating — the costs often outweigh the tax saving for small portfolios. ### Pros - Multiple specialist BTL lenders compete on remortgage business. - Capital raising opens portfolio growth opportunities. - 5-year fixes give lower stress rates and easier ICR passes. - Product transfers are fast and avoid re-affordability checks. - Limited company restructure can improve after-tax returns. ### Cons - ICR refinance gap is a real issue for many 2021-era landlords. - Rates 1.5%–2% above original 2019–2021 fixes. - Arrangement fees 1.5%–3% on BTL products. - Incorporation triggers CGT and SDLT — usually expensive. - Falling onto SVR even briefly costs hundreds in interest. ## Frequently asked questions ### When should I remortgage my buy-to-let? ### Is BTL remortgaging harder than residential? ### Can I remortgage a BTL to release equity? ### Does Section 24 affect my BTL remortgage decision? ### What if my BTL doesn't pass current ICR? ### Are product transfers (PTs) better than full remortgages on BTL? ## Related guides [ ### BTL Interest-Only Calculator Stress-test your ICR at 5.5%–7%.
