Why Airbnb breaches most UK mortgages
Standard residential mortgages require owner-occupation. Standard BTL mortgages require long-term tenancies under AST (or PRT in Scotland). Airbnb falls into neither category — it's commercial short-term accommodation. Mortgage lenders care about this for three reasons: void periods are higher, wear and tear is significantly greater, property risk profile changes (higher fire/safety risk from frequent unknown occupants), and the tenant rights and recourse position is entirely different from a long-let.
Most UK mortgage offers contain a clause prohibiting short-term letting without express lender consent. Breaching that clause makes the loan immediately repayable in principle, and at minimum allows the lender to revert the rate to SVR or impose penalty pricing.

How rental coverage is calculated
Lenders apply one of three approaches:
- Holiday-let income projection from an accredited letting agent showing low/mid/high season rates. Averaged across 30 lettable weeks per year for ICR purposes. Common in established holiday let areas.
- Higher of holiday let projection or AST equivalent — lender takes the more conservative figure of professional holiday letting projection vs equivalent long-let rent valuation.
- AST equivalent only — new short-let investors with no track record are often assessed against long-let rent valuation, ignoring potential Airbnb upside until the property has 12 months of trading.
ICR stress rates are typically 5.5%–7% with 125%–145% coverage required.
UK planning and licensing regime — rapidly tightening
- Scotland (mandatory since 2024): Short-Term Let Licensing under each local authority. Edinburgh has Control Areas requiring full planning permission for entire-home short lets in some streets.
- England: Short-Term Let Registration scheme rolling out under Levelling Up Act. Initially a national register; planning controls likely to follow.
- London (since 2017): 90-night cap per year on entire-home short lets without planning permission. Airbnb enforces the cap automatically on London listings.
- Wales: Statutory holiday let registration scheme rolling out 2025–2026.
- Local authority discretionary powers: increasing across UK to restrict or licence short lets.
Tax treatment of UK Airbnb / holiday let income
From April 2025 the Furnished Holiday Let (FHL) regime was abolished by HMRC. Holiday let income is now treated identically to other rental income:
- Section 24 mortgage interest restriction applies (basic-rate-tax-credit only for personal-name landlords).
- No more 100% capital allowances on FHL fixtures.
- Pension contributions no longer treated as relevant earnings from FHL income.
- Capital Gains Tax — no more entrepreneurs' relief / business asset disposal relief on disposal.
For higher-rate-taxpayer landlords this is a substantial change. Many holiday let owners are restructuring into limited companies to escape Section 24.
Practical considerations before applying
- Confirm the local authority permits short letting (or that you have planning permission / licence).
- Get an income projection from at least two accredited holiday letting agents.
- Plan for 30–35 lettable weeks/year as the realistic average outside prime tourist hotspots.
- Budget for high turnover wear-and-tear: linen, cleaning, breakages, intensive maintenance.
- Factor in management fees of 18%–25% if using a full-service letting agent.
- Buildings insurance must be commercial holiday let policy, not standard residential.
