Are Pre-Letting Expenses Tax Deductible? (2026)
Last updated 27 June 2026 · 7 min read · By the LandlordTaxAi Editorial Team
The short answer
Often yes. Under the pre-trading rules, revenue costs you incur before letting starts can still be claimed: if a cost was incurred within seven years before the business began, would have been allowable had it already started, and isn’t relieved elsewhere, it’s treated as incurred on the first day of letting. Capital costs don’t qualify.
New landlords often assume costs before the first tenant moves in are lost. They’re usually not — the pre-letting (pre-trading) rules let you carry qualifying revenue expenses into your first period of letting. This guide explains the seven-year rule, what qualifies, and the capital trap.

Pre-trading revenue costs within 7 years before letting are treated as incurred on day one. Capital costs don't qualify. Estimate only.
The seven-year rule
The pre-trading relief (under section 57 ITTOIA, reflected in HMRC’s Property Income Manual) treats qualifying revenue expenditure incurred in the seven years before the rental business commences as if it were incurred on the first day of letting. So you don’t lose the cost just because you paid it before the first tenant arrived.
The three tests: incurred within seven years before letting begins, would have been allowable if the business had already started, and not otherwise relieved.
What qualifies — and what doesn’t
Typical qualifying costs are the revenue expenses of getting ready to let — advertising for tenants, certain professional fees, insurance, pre-letting cleaning and minor repairs. What doesn’t qualify is anything capital: the property purchase itself, or improvements. And watch a common trap — works to make a newly-bought, run-down property lettable can be capital if they’re really part of acquiring the asset in usable condition.
| Pre-letting cost | Qualifies under the rule? |
|---|---|
| Advertising for tenants | Yes (revenue) |
| Insurance before first let | Yes (revenue) |
| Pre-letting cleaning / minor repairs | Often yes (revenue) |
| The property purchase price | No (capital) |
| Improvements / refurb to a derelict buy | Often capital |
If you bought a run-down property cheaply because it needed work to be lettable, that initial work is often capital — a borderline area worth checking with an accountant.
When does the business “start”?
Your rental business generally begins when the first property is let (or genuinely available and being actively marketed to let). Costs from the seven years before that point, meeting the tests above, are pulled into your first period — so keep dated invoices from the moment you decide to let.
Don’t lose your start-up costs
LandlordTaxAi reads your bank statements and helps categorise pre-letting and ongoing costs against the right HMRC category — so qualifying start-up expenses make it into your first MTD period.
See how it worksA worked example
A landlord prepares a property and first lets it in 2026/27.
| Tenant advertising (before first let) | £200 — qualifies |
| Pre-letting clean + minor repairs | £350 — qualifies |
| Insurance before the tenancy | £150 — qualifies |
| Treated as incurred on day one | £700 deducted in first period |
All £700 of qualifying revenue costs is treated as incurred on the first day of letting and claimed in that first period.
