The London 90-day rule Airbnb regulation remains one of the most significant constraints facing short-term rental hosts in the capital. This temporary accommodation limit, introduced in 2015, restricts most residential properties to just 90 nights of short-term letting per calendar year without planning permission. As we move through 2025, understanding these restrictions and your options for legitimate hosting has never been more crucial for maximising your rental income whilst staying compliant.
What Is the London 90-Day Rule for Airbnb?
The London 90-day rule limits short-term letting of residential properties to 90 nights per calendar year without requiring planning permission. This applies to all stays under 90 consecutive nights where the property isn't the guest's main residence.
Introduced through the Deregulation Act 2015, this rule covers the entirety of Greater London—all 32 boroughs plus the City of London. The legislation was designed to prevent the wholesale conversion of residential housing into tourist accommodation, protecting London's housing stock for long-term residents.
The 90-night limit applies per property, not per platform. This means if you list on Airbnb, Booking.com, and Vrbo simultaneously, the combined bookings across all platforms cannot exceed 90 nights annually. Each calendar year resets on 1st January, regardless of when you started hosting.
Crucially, the rule applies to properties where short-term letting isn't the established use. If your property was lawfully used as short-term accommodation before the rule came into effect, different regulations may apply.
Which London Properties Are Affected by the 90-Day Restriction?
The restriction applies to all residential properties in Greater London used for short-term letting, including flats, houses, spare rooms, and annexes where the guest doesn't reside permanently.
This includes:
- Entire properties: Flats, houses, and maisonettes let whilst owners are away
- Spare rooms: Bedrooms in occupied homes where hosts remain present
- Self-contained annexes: Garden flats, converted garages, or granny annexes
- Investment properties: Buy-to-let properties used for short-term rather than long-term rental
Certain properties may be exempt:
- Hotels, B&Bs, and guesthouses with established commercial use
- Properties with existing short-term rental planning permission
- Some serviced apartments with commercial classification
- Properties where short-term letting was the established use before 2015
If you're unsure about your property's classification, check with your local borough council's planning department. Each borough maintains records of planning permissions and established use classifications.
How Is the 90-Day Limit Calculated and Monitored?
The 90-day limit runs from 1st January to 31st December each year and includes all nights where paying guests stay, regardless of booking length or platform used.
London boroughs monitor compliance through several methods:
Platform data sharing: Some boroughs have agreements with major platforms to share booking data. Airbnb, for example, provides anonymised data to certain councils showing booking patterns and potential violations.
Complaint-driven investigations: Neighbours can report suspected violations. Councils investigate properties receiving multiple complaints about noise, parties, or excessive tourist activity.
Planning enforcement officers: These officers actively monitor short-term rental activity, particularly in areas with high tourist density or resident complaints.
As a host, you're responsible for tracking your own nights. LetGrow's free listing analysis can help you understand your booking patterns and occupancy rates to ensure you stay within legal limits whilst maximising revenue.
Most successful hosts use simple spreadsheets or calendar apps to log each booking's check-in and check-out dates. Some property management systems also provide automated tracking, though self-managing hosts often prefer manual oversight for accuracy.
What Happens If You Exceed the 90-Day Limit?
Exceeding the 90-day limit without planning permission constitutes a breach of planning control, potentially resulting in enforcement action, fines up to £20,000, and legal costs.
Enforcement typically follows this escalation path:
Initial investigation: The council investigates reported violations, often requesting booking records and platform data. Hosts usually receive informal contact requesting information about their letting activity.
Breach of condition notice: If violations are confirmed, councils issue formal notices requiring cessation of unauthorised short-term letting. These notices typically allow 28 days for compliance.
Enforcement action: Continued violations can result in enforcement notices, requiring immediate cessation and potentially demanding restoration of lawful residential use.
Prosecution: Persistent violators face prosecution under planning law, with fines reaching £20,000 plus legal costs. Some boroughs have secured convictions with substantial financial penalties.
Beyond financial penalties, violations can affect:
- Mortgage agreements (some lenders prohibit short-term letting)
- Insurance coverage (residential policies may not cover commercial activity)
- Leasehold obligations (many leases restrict or prohibit subletting)
- Future planning applications (previous violations influence decision-making)
Airbnb Planning Permission London: When Do You Need It?
You need planning permission for short-term letting in London when exceeding 90 nights annually, changing a property's established use, or operating in areas with Article 4 directions restricting permitted development rights.
Planning applications typically require demonstrating:
No adverse impact on neighbours: Evidence that increased comings and goings won't disturb residential amenity. This might include management plans, guest screening procedures, or noise mitigation measures.
Adequate waste and parking provision: Short-term guests generate different waste patterns and parking demands than permanent residents. Applications should address these practical considerations.
Character preservation: In conservation areas or areas of special character, applications must demonstrate the proposal preserves the area's residential character.
Application costs vary by borough but typically range from £234 for householder applications to £462 for full planning permission. Processing times average 8-12 weeks, though complex applications may take longer.
Several factors influence approval chances:
- Local housing pressure: Boroughs with acute housing shortages often refuse applications that remove residential accommodation
- Tourism saturation: Areas already saturated with short-term rentals face stricter scrutiny
- Neighbour objections: Multiple objections citing noise, antisocial behaviour, or parking issues significantly impact applications
- Management proposals: Robust management plans addressing potential issues improve approval prospects
Borough-Specific Variations: How London Councils Differ
While the 90-day rule applies London-wide, individual boroughs implement additional restrictions and enforcement approaches, creating a complex patchwork of local regulations.
Westminster: As London's tourist heart, Westminster operates stringent enforcement with dedicated short-term rental officers. The borough has secured numerous prosecutions and actively monitors platforms for violations. Additional licensing requirements apply in some areas.
Camden: Camden requires registration for all short-term rentals and has introduced additional safety and management standards. The borough's dense residential areas mean neighbour complaints are common and swiftly investigated.
Tower Hamlets: This borough has introduced Article 4 directions removing permitted development rights in areas near tourist attractions, effectively requiring planning permission for any short-term letting.
Kensington and Chelsea: Known for strict enforcement and low approval rates for planning applications, this borough prioritises protecting residential character in expensive neighbourhoods popular with tourists.
Hackney: Hackney requires hosts to register properties and comply with additional safety standards. The borough has been proactive in working with platforms to monitor compliance.

Legal Alternatives: Maximising Revenue Within the Rules
Smart hosts maximise their 90-day allocation through strategic pricing, optimal booking patterns, and complementary revenue streams whilst maintaining full legal compliance.
Premium pricing strategy: Rather than competing on price, focus on creating a premium experience justifying higher nightly rates. This maximises revenue per available night within your 90-day limit.
Seasonal concentration: Concentrate bookings during London's peak tourism seasons (June-September, December) when demand and rates are highest. Use quieter months for property maintenance and personal use.
Minimum stay requirements: Longer stays reduce turnover costs and cleaning frequency whilst potentially attracting more responsible guests. However, balance this against occupancy rates—too high minimums can reduce bookings.
Platform optimisation: Ensure your listing ranks highly in search results to attract quality bookings quickly. Professional photos, compelling descriptions, and competitive pricing within your premium strategy are essential.
Complementary income streams: Consider long-term rentals during off-peak periods, though ensure lease agreements permit subsequent short-term letting when you switch back.
Multiple property strategy: Some hosts acquire multiple properties, each operating within their 90-day limits. This scales income whilst maintaining compliance, though requires significant capital investment.

What Changes Are Expected for London Short-Term Rentals in 2025-2026?
The government is considering a national registration scheme for short-term rentals, while London boroughs continue tightening local enforcement and introducing additional licensing requirements.
Key developments to monitor include:
National registration scheme: The government has consulted on requiring all short-term rental properties to register with local authorities. This would create a comprehensive database enabling better monitoring and enforcement.
Enhanced data sharing: Platforms may be required to share more detailed booking data with local authorities, making it easier to identify properties exceeding the 90-day limit.
Borough-specific licensing: More London boroughs are introducing additional licensing schemes with safety, insurance, and management requirements beyond basic planning compliance.
Tax implications: HMRC continues strengthening reporting requirements for short-term rental income, with platforms required to report host earnings automatically.
Insurance developments: The insurance industry is developing products specifically for short-term rental hosts, addressing coverage gaps in traditional residential policies.
For hosts, these changes emphasise the importance of maintaining detailed records, ensuring full legal compliance, and staying informed about local developments in their specific boroughs.
Frequently Asked Questions
Can I reset my 90-day limit by taking a break from hosting?
No, the 90-day limit runs per calendar year (January-December) regardless of when you start or stop hosting. Taking breaks doesn't reset or extend your allocation within that year.
Does the 90-day rule apply if I rent out my spare room while living there?
Yes, the rule applies to all short-term letting in residential properties, including spare rooms in occupied homes. The 90-day limit covers any arrangement where guests pay to stay temporarily.
What if my guests extend their stay beyond the original booking?
Extensions count towards your 90-day limit based on actual nights stayed, not the original booking length. You're responsible for tracking total nights regardless of how bookings are modified.
Can I exceed 90 days if I get planning permission partway through the year?
Planning permission typically allows unlimited short-term letting from the approval date, but you cannot retrospectively authorise nights already used under the 90-day allowance before permission was granted.
How do London boroughs coordinate enforcement across multiple platforms?
Many boroughs use sophisticated data analysis comparing booking patterns across platforms, while some have formal data-sharing agreements with major platforms to identify potential violations.
What evidence do I need to keep to prove compliance?
Maintain detailed records of all bookings including dates, guest numbers, platform used, and payment amounts. Keep platform correspondence, guest communications, and any relevant planning documents or permissions.
Understanding and complying with London's 90-day rule requires careful planning and detailed record-keeping, but it needn't prevent successful short-term rental hosting. By focusing on premium positioning, strategic booking patterns, and full legal compliance, you can build a profitable hosting business within these constraints.
