UK Buy-to-Let Yield Calculator

UK average gross BTL yield is approximately 5.8%. Yields above 7% are generally considered good, while below 4% may not justify the investment risk after accounting for costs, voids, and tax. Yields vary significantly by region, with the North East and North West of England typically offering higher yields than London and the South East.

Section 24 phased out mortgage interest tax relief for individual landlords between 2017 and 2020. Mortgage interest is no longer a deductible expense for income tax purposes. Instead, basic rate (20%) landlords receive a 20% tax credit on mortgage interest. Higher and additional rate landlords are taxed on rental income that is largely offset by mortgage costs, making BTL less profitable for them.

Yes. In England and Northern Ireland, additional properties including buy-to-let incur a 5% SDLT surcharge on top of standard rates. Scotland charges an 8% Additional Dwelling Supplement under LBTT, and Wales charges a 6% higher rate under LTT. These surcharges apply from completion and must be paid within 14 days.

Most BTL mortgage lenders require a minimum 25% deposit (75% LTV). Some specialist lenders offer 80% LTV but at a higher interest rate. Lenders also stress-test the mortgage at 125-145% of the monthly rental income against mortgage payments to ensure affordability, so rental income level is as important as deposit size.

Yes, many landlords purchase BTL properties through a Special Purpose Vehicle (SPV) limited company. Corporation tax at 25% applies instead of income tax, and mortgage interest is fully deductible as a business expense. However, extracting profits via dividends incurs additional tax, and CGT rules on disposal differ. Professional accounting advice is recommended before choosing this structure.

Common BTL costs include: letting agent fees (8-15% of rent for full management), landlord buildings and contents insurance, maintenance and repairs, ground rent and service charges for leasehold properties, gas safety and electrical inspection certificates, Energy Performance Certificates, and accounting fees. Budget approximately 20-30% of gross annual rent for total running costs.

When you sell a BTL property at a profit, Capital Gains Tax applies on the gain above the annual CGT exempt amount (£3,000 for 2026/27). Residential property gains are taxed at 18% for basic rate and 24% for higher/additional rate taxpayers. You must report and pay within 60 days of completion through HMRC's CGT on UK property service.
