Holiday let mortgages occupy a distinct niche between standard residential mortgages and buy-to-let products. The income assessment methodology, lender criteria, property requirements, and tax treatment all differ from long-term rental property finance — and the tax position changed significantly in April 2025.
What Is a Holiday Let Mortgage — A holiday let mortgage is a specific product designed for properties that will be let to short-term guests (typically on contracts shorter than 31 days) rather than long-term tenants. Because short-term lettings generate higher gross income but with more vacancy risk, lenders use a different rental income assessment model. Some lenders use peak, mid, and low-season occupancy assumptions. Others use a projected annual income from a specialist valuation. Standard buy-to-let products are not suitable and should not be used for properties that will be let on a short-term basis.
Income Assessment — Unlike standard buy-to-let mortgages, which assess rental income against the mortgage payment at a stressed rate, holiday let lenders look at projected annual rental income across seasonal occupancy. Typical assumptions are 30 weeks occupancy per year at average nightly rates — which for popular coastal or rural locations can produce annual income well above what a long-term tenancy would generate on the same property. Some lenders require a professional holiday letting agency to provide an occupancy and income assessment.
Lenders Offering Holiday Let Mortgages — The market is more specialised than standard buy-to-let. Key lenders include Bath Building Society, Harpenden Building Society, Ipswich Building Society, Leek United Building Society, Newcastle Building Society, The Mortgage Works (within their portfolio landlord criteria), Shawbrook Bank, Precise Mortgages, and Hinckley and Rugby Building Society. This is a smaller pool than standard BTL and rates are typically 0.25 to 0.75 percent higher.
Property and Location Requirements — Not all properties qualify. Most lenders require the property to be in a recognised holiday let location — coastal areas, national parks, rural retreats, tourist cities. Urban flats used for short-term letting in non-tourist locations may face more scrutiny. Properties managed through professional holiday letting platforms (Sykes, Hoseasons, Airbnb, Booking.com) are generally more acceptable than informally managed properties. The property must meet safety requirements including gas safety certification, electrical inspection, fire risk assessment, and appropriate furnishings.
Personal Use — Most holiday let mortgages allow the owner to use the property personally for a defined period each year (typically 90 days). This distinguishes holiday lets from pure investment properties. Lenders may restrict personal use during peak season (summer months, Christmas) when rental income potential is highest. Always check the specific terms of the mortgage offer.
The FHL Tax Changes from April 2025 — The UK's Furnished Holiday Lettings (FHL) regime was abolished from 6 April 2025. This was a significant change that affected the tax treatment of holiday let income and expenses. Under the old FHL rules, holiday let income qualified as trading income, meaning property owners could offset mortgage interest fully against income (avoiding the Section 24 restriction that applies to long-term landlords), claim capital allowances on furnishings and equipment, potentially qualify for Business Asset Disposal Relief on sale (reducing CGT to 10 percent), and make pension contributions from FHL profits.
From April 2025, holiday let income is treated the same as standard rental income under the property business rules. This means: mortgage interest relief is restricted to a 20 percent tax credit for individual landlords (the Section 24 restriction now applies). The annual investment allowance and capital allowances on furnishings are replaced by the replacement of domestic items relief (which covers like-for-like replacements only). Business Asset Disposal Relief no longer applies to holiday let disposals. The change particularly affects higher-rate taxpayers with mortgaged holiday lets.
Limited Company Structures Post-April 2025 — As with long-term buy-to-let, purchasing holiday lets through a limited company avoids the Section 24 restriction and allows full mortgage interest deduction. Given the loss of FHL tax advantages, the case for corporate ownership has strengthened for new holiday let investors. The additional 5 percent stamp duty surcharge and company mortgage rate premium apply as with standard BTL limited company purchases.
Yields and Investment Case — Holiday lets in prime UK locations typically generate gross yields of 8 to 15 percent on purchase price. Cornwall, the Lake District, the Cotswolds, and the Scottish Highlands consistently show strong occupancy rates. Urban locations — Edinburgh, Bath, York — can achieve high nightly rates but face greater competition and potential local authority short-let licensing requirements (Edinburgh introduced short-term let licensing in 2022 as the first UK city to do so). The investment case depends heavily on location selection, property management quality, and realistic occupancy assumptions.
Planning and Licensing — Some areas require planning permission for change of use to short-term holiday let. Article 4 Directions in parts of London restrict short-term letting of entire properties to 90 nights per year without planning permission. Edinburgh's short-term let licensing regime has spread awareness of regulatory risk across the sector. Check local planning policy and licensing requirements before purchasing, as enforcement has increased.
