Introduction
The allure of a second home in the UK—whether a countryside retreat, a city pied-à-terre, or a seaside holiday let—remains strong in 2025. However, tighter tax rules and stricter mortgage criteria mean careful planning is essential. This guide walks you through UK-specific financing, legal obligations, and profit strategies for second-home buyers.

Tax Implications for UK Second Homes
- Stamp Duty Land Tax (SDLT):

- Exemptions: If replacing your main residence (sell within 3 years).
- Capital Gains Tax (CGT):
- Rate: 18%–28% on profit when selling (vs. 10%–20% for primary homes).
- 2025 Allowance: £3,000 tax-free (down from £6,000 in 2024).
- Income Tax:
- Holiday Lets: Declare rental income and claim allowable expenses.
- Furnished Holiday Let (FHL) Status: Requires 210 days availability and 105 days booked.
Buy-to-Let vs. Holiday Let: Which Is Better in 2025?
| Factor | Buy-to-Let | Holiday Let |
| Rental Income | Stable (long-term tenants) | Higher (peak season pricing) |
| Tax Benefits | Mortgage interest tax relief (20%) | Business rates instead of council tax |
| Effort Required | Low (managed via letting agent) | High (frequent turnovers, cleaning) |
Top UK Locations for Second Homes in 2025
- Cornwall: Average holiday let yields of 8%–12% (Postcode: TR postcodes).
- Lake District: High demand for rural retreats (Average price: £350k).
- Edinburgh: Strong capital growth (6% YoY) and festival-driven rentals.

Case Study: A Holiday Let in Devon
John and Lisa bought a 3-bed cottage in Salcombe for £450k (25% deposit). With a holiday let mortgage at 5.2%, their repayments are £1,400/month. Summer bookings (£1,800/week) and winter discounts (£800/week) generate £48k/year gross. After costs, they net £24k/year—a 10.6% yield.
5 Tips to Minimise Costs
- Offset Stamp Duty: Purchase a cheaper property below £40k SDLT thresholds.
- Use a Ltd Company: Pay 19% corporation tax vs. higher income tax rates (if portfolio grows).
- Energy Efficiency Upgrades: Qualify for 0% VAT on insulation/solar panels (2025 UK scheme).
- Claim Allowable Expenses: Mortgage interest, maintenance, agent fees.
- Switch to Green Mortgages: Lower rates for EPC A/B properties (e.g., NatWest Green Mortgages).
2025’s Regulatory Changes to Watch
- Short-Let Licensing: Mandatory registration for Airbnb-style lets in London, Edinburgh, and Brighton.
- EPC Upgrades: All rental properties must meet EPC C by 2028 (plan retrofits early).
- Holiday Let Tax Tweaks: Consultation on limiting FHL perks for non-local owners.
