Frequently asked questions
- What rental expenses are allowable for UK landlords?
- Most day-to-day running costs are allowable if incurred wholly and exclusively for the rental business — letting agent fees, repairs and maintenance, insurance, ground rent, accountancy fees, and utilities you pay. Capital improvements are not allowable as revenue expenses but can be added to the property's base cost for CGT.
- What is the difference between capital and revenue expenses?
- Revenue expenses restore the property to its previous condition (e.g. replacing a like-for-like boiler) and reduce taxable rental profit. Capital expenses improve the property beyond its original state (e.g. an extension or kitchen upgrade) and are added to the cost base for capital gains tax when you sell.
- Can I claim mortgage interest as a rental expense?
- Individual landlords cannot deduct mortgage interest as a rental expense. Instead, you receive a basic-rate (20%) tax credit on the interest under the Section 24 rules. Limited companies can still deduct mortgage interest in full.
