Airbnb & Short Let Electrical Safety London: The 2026 Compliance Guide

The Deregulation Act 2015 allows London hosts to let an entire property as a short-stay rental for up to 90 nights per calendar year without planning permission. Exceeding 90 nights converts the use to a "material change" requiring planning consent — a process most Westminster, Camden and Kensington & Chelsea applications fail.

Where the host stays in residence and rents only a room ("room let" or "live-in host"), the 90-day cap does not apply. The activity sits inside the host's own ordinary residence.

For electrical safety the 90-day question is largely irrelevant: even letting for a single night under 90 brings the host inside the Electrical Safety Standards (Private Rented Sector) Regulations 2020 if the let is for residential occupation in return for payment. The Regulations apply to "specified tenancies" which the courts have read broadly enough to cover short-let arrangements.

Short-let hosts need a satisfactory EICR conducted within the last 5 years before the first paying guest arrives. The certificate must be supplied to any guest staying long enough to constitute a "tenancy" (a debated boundary, but the conservative reading captures stays of 28+ days).

The practical position taken by most short-let insurers: keep a current EICR on file regardless of stay length. The certificate is requested by Airbnb host insurance, Booking.com's host protection programme, and AirCover claims handlers.

EICR cost for a typical 1-2 bed London Airbnb flat: £89.99, same day certificate, can be bundled with EPC at £79.99 for combined £155 instead of £170 paid separately.

Short-let properties fall under the same domestic fire alarm standard as long-let HMOs: BS 5839-6 Grade D LD2. That means mains-powered alarms with battery backup, interconnected so that one detection sounds all units, and coverage in every circulation area plus the kitchen and any room of high fire risk.

The Smoke and Carbon Monoxide Alarm (England) Regulations 2015 (extended 2022) make smoke alarms on every storey and CO alarms in every room with a fuel-burning appliance a legal minimum across all rented accommodation including short-lets. The 2022 amendment closed the gap that previously excluded social housing and tightened the response time required of landlords from "as soon as possible" to within 24 hours of reported failure.

For multi-storey Airbnb properties (a converted mews house, a maisonette, a three-floor townhouse) a Grade D LD2 retrofit costs £450-£700 fitted. For a single-storey flat with kitchen and hallway coverage the install is closer to £250-£350.

A carbon monoxide alarm must be installed in any room of the property where a fixed combustion appliance is located — gas boiler, gas hob, gas fire, solid-fuel stove. The alarm must comply with BS EN 50291-1 and be sited per manufacturer guidance, typically 1-3m from the appliance at a high level.

For combi boilers in airing cupboards, kitchens or utility rooms the same rule applies. The 2022 amendment specifically extended CO alarm coverage from solid-fuel-only to all combustion appliances.

Battery-powered sealed-cell CO alarms with a 10-year battery and end-of-life indicator are accepted. Hard-wired CO alarms are not required but are sometimes specified by host insurance for high-volume short-lets. Typical fit cost: £25-£40 per alarm.

Booking.com's 2024 host policy update added an EPC documentation field. Listings without a valid EPC code visible to the guest are progressively deprioritised in search results across Booking.com and Expedia.

Airbnb does not directly require an EICR upload, but AirCover claims for electrical fire damage are routinely refused where no EICR is on file. Several brokers (Pikl, Guardhog) writing dedicated short-let insurance now condition cover on annual EICR + interconnected alarm + CO compliance.

Platform compliance is increasingly automated. Holiday-let-specific listing platforms (Plum Guide, OneFineStay) require uploaded EICR, gas safety, EPC and FRA certificates at listing onboarding and renew the reminder annually.

A property classified as a short-let above the 90-day threshold can attract council enforcement under planning, ULEZ-zone hotel licensing rules (where applicable) and the Greater London Authority short-term rental register that comes into force progressively across 2025-2026.

Westminster, Kensington & Chelsea, Camden and Tower Hamlets actively enforce the 90-day cap using booking-platform data sharing — the platforms now disclose nights booked per host to the GLA on a quarterly basis. Enforcement is reactive (complaint-driven) but the data trail exists.

A short-let property mis-classified as a long-term residential let to access cheaper insurance is a separate problem: the policy is voidable on discovery, and a fire or theft claim is at risk of refusal regardless of EICR compliance.

A Camden host received a £10,000 Civil Penalty Notice in October 2024 for letting an unfurnished flat as a short-stay rental without a valid EICR after a guest reported a sparking socket. The CPN was upheld at First-tier Tribunal in January 2025.

A Kensington & Chelsea enforcement action in 2024 prosecuted a host running three flats above the 90-day cap. The penalty package combined planning enforcement (£15,000), failed-EICR penalty (£8,000) and fire safety improvement notice. The case made the LGA enforcement summary published April 2025.

Hackney issued 17 short-let-related EICR notices across 2024-25, mostly against converted house-share properties marketed as Airbnb but in practice operating as rolling 30-day-plus tenancies. The borough treats these as full PRS lets for compliance purposes.
