Serviced Accommodation Rules 2026: Calculating Net Profit on Short-Term Lets
Serviced accommodation (SA) and short-term letting platforms like Airbnb and Booking.com have promised UK property investors eye-watering night rates. Taking a flat that yields £1,200 a month on a long-term tenancy and renting it out for £150 a night looks like an effortless tripling of income. However, between sweeping statutory regulatory reforms in England, council planning use classes, and the abolition of the Furnished Holiday Let (FHL) tax regime, operating serviced accommodation in 2026 requires rigorous cashflow underwriting.
1. The 2026 Regulatory Landscape for UK Short-Term Lets
The UK government has introduced decisive reforms to regulate short-term holiday rentals across England:
- New Use Class C5 (Short-Term Let): Under planning rules, dwellings used as short-term holiday lets are classified under a distinct planning class (Class C5). Local authorities can implement Article 4 directions requiring full planning permission to switch from C3 (residential) to C5.
- Mandatory National Registration Scheme: All short-term let operators must register on a centralized national register, demonstrating compliance with fire safety, electrical testing, and building standards.
- The 90-Day Rule in Greater London: In Greater London, residential properties cannot be let on a short-term basis for more than 90 nights per calendar year without formal planning permission. Councils enforce this aggressively through data-sharing agreements with booking platforms.
2. The Death of FHL Tax Advantages
Historically, properties qualifying as Furnished Holiday Lets (FHL) enjoyed massive tax advantages over standard buy-to-lets: 100% mortgage interest deductibility (bypassing Section 24), Capital Allowances on fixtures and furnishings, and Business Asset Disposal Relief (10% CGT). The abolition of the FHL regime aligns holiday lets with standard buy-to-let taxation: mortgage interest is restricted to a 20% basic rate tax credit, and capital allowances are severely limited.
3. The True Cost Stack of Serviced Accommodation
To calculate real net profit, you must strip out the substantial operational deductions that standard buy-to-let calculators ignore:
| Expense Category | Typical Cost / Deduction | Impact on Cashflow |
|---|---|---|
| OTA Platform Commissions (Airbnb / Booking.com) | 15% to 18% of gross booking revenue | Substantial direct top-line deduction. |
| Cleaning & Laundry Turnover | £50 to £90 per turnover check-out | Short 2-night stays heavily penalize net yield unless passed to guests. |
| Channel Manager & Dynamic Pricing Software | £40 to £80 / month (e.g. PriceLabs, Hospitable) | Essential for algorithmic pricing optimization. |
| Commercial Utility & WiFi Bills | £250 to £400 / month | Guests run heating, air conditioning, and laundry with zero conservation. |
| Commercial Host Insurance & Public Liability | £60 to £100 / month | Standard home insurance is voided by short-term letting. |
| Consumables & Replenishment | £50 to £80 / month | Coffee, toiletries, welcome hampers, replacement glassware. |

5. Strategic Verdict
Serviced Accommodation still delivers higher net yield than standard tenancies, but the margin has narrowed dramatically. Unless you achieve an occupancy rate above 65% or cater to high-paying corporate/contractor long stays (where cleaning friction is low), the operational intensity may not justify the added regulatory and tax burden.
