The Furnished Holiday Lettings (FHL) regime was a set of UK tax rules that treated qualifying holiday let properties as a trading business rather than an investment. This entitled FHL owners to a range of tax benefits not available to standard buy-to-let landlords, including full mortgage interest deduction, capital allowances, Business Asset Disposal Relief on Capital Gains Tax, and the ability to treat profits as Net Relevant Earnings for pension purposes. The regime applied to properties let on a short-term basis that met minimum availability and occupancy thresholds.
