Frequently asked questions
What percentage of property value should I budget for maintenance?
The standard rule of thumb for UK rental properties is 1–2% of property value per year for maintenance and repairs, depending on age and type. A new build at 1% and a Victorian terrace at 2% are appropriate starting points. On a £250,000 property, this is £2,500–£5,000/year.
For HMOs — where wear is significantly higher with multiple occupants — 2–3% is more appropriate. A 5-bed HMO valued at £280,000 should have £5,600–£8,400/year budgeted for maintenance and compliance, including the higher frequency of plumbing, appliance, and redecoration work that multiple occupancy generates.
Note that this is a smoothed annual budget — in practice, maintenance spend is lumpy. A year with no boiler failure and no tenant changeover may cost £800; a year with a boiler replacement and a full redecoration may cost £7,000. The budget represents the long-run average, not the expected cost in any specific year.
Can I deduct maintenance costs from rental income for tax?
Repairs and maintenance costs that restore a property to its original condition are fully deductible against rental income for UK landlords (for individual landlords, subject to the usual income tax rules; for limited company landlords, deductible as a business expense against corporation tax). This includes: plumbing repairs, boiler servicing, redecorating, replacing like-for-like fixtures and fittings, and reactive maintenance.
Capital improvements — work that improves the property beyond its original state or adds new value (e.g. adding an extension, upgrading from a standard to a premium kitchen) — are not deductible as maintenance. Instead, they reduce the Capital Gains Tax liability on eventual sale. The distinction between repair (revenue expenditure, deductible) and improvement (capital expenditure, not deductible) is an important one — keep records and receipts for all works, and discuss ambiguous cases with your accountant.
Should I use a managing agent or handle maintenance myself?
Self-management saves the agent's management fee (8–15% of rent) but requires you to handle all maintenance coordination directly — finding contractors, getting quotes, overseeing work, and being available for emergencies. For a landlord with one or two properties and local contractor relationships, self-management is workable. For three or more properties, or for landlords managing from a distance, the management fee is usually justified by time saved and professional oversight.
A well-chosen managing agent with good contractor relationships should not cost more in total than self-management once you account for the opportunity cost of your time. The critical variable is agent quality — a poor agent managing maintenance badly can cost more in unnecessary works, missed problems, and tenant dissatisfaction than the fee saves. Interview multiple agents and ask specifically about their contractor network and maintenance response standards.
