How This Tool Works
📋 Purpose
UK landlords face two fundamentally different letting models: traditional long-let (1 tenant, 12-month lease, predictable rent) or Airbnb-style short-let (many guests, higher gross, much higher operating cost and regulation). The right answer depends on your property type, location, tax band and risk appetite. This tool runs both models with correct post-2025 tax treatment and surfaces the occupancy you\u2019d need for short-let to beat long-let.
⚙️ How It Works
- 1Enter your property value, bedrooms and type.
- 2Enter your expected long-let monthly rent.
- 3Enter your expected short-let nightly rate and occupancy.
- 4Flag London + primary-residence status for regulatory rules.
- 5We apply Section 24 income tax treatment to both models.
- 6We compute net profit, net yield and breakeven occupancy.
- 7We surface regulatory warnings (90-night cap, leasehold, 2026 registration).

Quick Tips
Jump-start your understanding with these essential tips
1 tenancy, 12-month lease, predictable income. Short-letting is a small business — admin, customer service, repeat listing optimisation.
Self-managing an Airbnb is typically 8–15 hours/week. At £25/hr that's £10,000–£20,000/yr of unpaid labour the tool does NOT deduct.
If you own a leasehold flat, 90%+ of leases prohibit short-lets. A single complaint from a neighbour can trigger forfeiture proceedings.
At 40% tax band you keep ~£1,500 less profit per £10,000 of mortgage interest vs the pre-2017 rules.
Standard buy-to-let policies do NOT cover short-lets. You need a dedicated short-let policy (e.g. Pikl, Guardhog) at 2x the cost.
Step-by-Step Guide
Follow these steps to get the most from this tool
Used for yield calculation and Section 24 tax estimate.
Check local comparables on Rightmove’s Sold Prices / Zoopla for 2-3 recent lettings nearby.
Use AirDNA or check your postcode on Airbnb to see top-3 comparables. Be honest about occupancy — 55% is a reasonable "no evidence" baseline.
Critical for the 90-night cap and planning warnings.
Section 24 bites hardest at Higher (40%) and Additional (45%). Basic-rate landlords are largely unaffected.
The chart shows short-let net profit at every occupancy level with the long-let baseline. The breakeven reference line shows the occupancy you need to match long-let profit.
Advanced Topics
Deep dives for advanced users
(1) Central London / Edinburgh / York / Bath — high nightly rates + strong year-round demand. (2) Primary residence under 90 nights — no planning needed. (3) Freehold house in tourism hotspot. (4) You're willing to self-manage or pay 15% management fee.
(1) Leasehold flat (lease likely prohibits short). (2) Provincial areas with low tourism. (3) You're a higher-rate taxpayer without a limited company. (4) You value predictable income and zero hospitality overhead.
From 2026 all English short-term lets require national registration (DCMS). From 2024 Scotland required short-term let licences (many councils use "control zones"). Wales is consulting on similar schemes. Regulation is tightening — factor a 10–15% operational risk into your short-let baseline.
Limited companies keep full mortgage interest deduction, pay 19–25% corporation tax and 8.75–39.35% dividend tax on withdrawal. For 3+ properties on higher-rate income it often beats personal ownership within 5 years. But transferring existing property triggers SDLT + CGT — always model with an accountant.
