PropCalc UK

Rent-to-rent (R2R) and serviced accommodation (SA) are control-not-own UK property strategies — you pay a head rent (or own the property), then sub-let on shorter terms or via platforms like Airbnb for a margin. The economics are very different from buy-to-let: high turnover, platform fees, cleaning, capex amortisation, and the £90,000 VAT threshold trap that catches operators who scale past a single property. The Furnished Holiday Lettings (FHL) tax regime was abolished on 6 April 2025, removing the favourable tax treatment SA used to enjoy.

Rent-to-Rent / Serviced Accommodation

Control-don't-own economics: head-rent or nightly rate, occupancy, cleaning, platform fees, and the VAT-threshold tripwire most spreadsheets miss.

Furnished Holiday Letting regime abolished 6 April 2025

SA / Airbnb properties no longer get FHL tax benefits. Mortgage interest is restricted to a 20% (22% from 2027) tax credit just like a standard BTL. No capital allowances on furniture/fittings (only s311A replacement-of-domestic-items relief). BADR, rollover relief, holdover relief — all gone. Profits no longer relevant earnings for pension contributions. This calculator treats SA income as ordinary residential rental.

Frequently asked questions

Answers to the questions UK property investors most often have about this tool and the underlying rules.

What changed in April 2025 for serviced accommodation?
The Furnished Holiday Lettings (FHL) tax regime was abolished. SA operators now follow standard residential rental rules: mortgage interest restricted under Section 24 (20% credit), no capital allowances on furniture (only the s311A replacement-of-domestic-items relief), no BADR or rollover relief on disposal, profits no longer "relevant earnings" for pension contributions.
When does the £90,000 VAT threshold apply?
Once your taxable turnover (annualised) exceeds £90,000, you must register for VAT and charge 20% on guest stays. For serviced accommodation, this often happens with just 1-2 properties in expensive areas — a £250/night unit at 60% occupancy grosses ~£54k/year per property. The calculator warns when projected revenue crosses the threshold.
Is R2R legal in the UK?
Yes, with the head landlord's written permission. Most standard ASTs prohibit sub-letting, so you need a commercial lease or a specific R2R agreement. Operating without permission breaches the head tenancy and can lead to eviction and damages.
