A short let needs a gas safety check if it has gas appliances, a valid electrical safety certificate, working smoke alarms and a carbon monoxide alarm wherever there is a combustion appliance, and proper fire precautions suited to the layout. These are largely the same obligations that apply to any rented property in England. What changes with a short let is who needs to understand them: a new, unfamiliar guest every few days rather than one tenant who has lived there for a year.
Gas safety
If the property has a gas boiler, hob, or any other gas appliance, it needs an annual gas safety check carried out by a Gas Safe registered engineer, and the resulting record kept on file. This is a legal requirement for rented property generally, and a short let does not sit outside it just because the occupants change every few nights. The certificate needs renewing every year without a gap, and a lapsed one is not something to notice after a guest has already checked in.
If the property has no gas supply at all, electric heating and an induction hob, for example, this requirement does not apply, though it is still worth having the electrical installation checked, which covers the same ground from a different angle.
Electrical safety
Rented property in England needs an Electrical Installation Condition Report confirming the fixed wiring is safe, carried out by a qualified electrician at set intervals. A short let should treat this the same way, kept current and not allowed to lapse. Beyond the fixed installation, it is worth having portable appliances in the property, kettles, toasters, hairdryers, anything guests will actually plug in, checked occasionally too. This is not always a strict legal requirement in the same way as the installation report, but guests use appliances harder and more carelessly than an owner would, and a short-let property turns over its guests often enough that a fault gets found by someone else's visit rather than your own.
Smoke and carbon monoxide alarms
Working smoke alarms are required on every storey of a rented property that has a room used as living accommodation, and a carbon monoxide alarm is required in any room with a solid fuel appliance and is sensible wherever there is a gas appliance too, even where it falls outside the strict legal requirement. The detail that catches short lets specifically is that alarms need to be tested, not just installed once. A tenant who lives somewhere for a year will probably mention a dead battery. A guest staying three nights is far less likely to, and may not even notice before they leave. Testing alarms as part of every cleaner's changeover routine, rather than relying on a guest to flag a problem, is the only way this reliably gets caught.
Fire safety more broadly
Beyond alarms, fire safety for a short let is really about two things: equipment and escape routes. A fire blanket and a small extinguisher in the kitchen are standard and inexpensive. Furniture and furnishings supplied in rented property need to meet fire safety regulations for fillings and labelling, which mostly affects sofas, mattresses and some soft furnishings bought secondhand or from unregulated sources rather than anything bought new from a normal retailer.
Escape routes matter more in a short let than in most tenancies because the occupant does not know the building. A guest who has never been in the flat before does not know instinctively which way leads out, whether a window opens, or where the nearest final exit from the building is. A short note near the door, the kind guests barely notice but will look for once in an emergency, covering the exit route and where the nearest alarm point or extinguisher is, costs nothing and is one of the few fire precautions that is specific to short-stay guests rather than copied from a standard tenancy.
If the property sits inside a larger building, a block of flats with shared corridors and stairwells, the building's own fire risk assessment and any related obligations sit with the freeholder or managing agent, not the individual flat owner. It is still worth knowing what that assessment says and whether it has anything to say about short-term letting specifically, because some do.
Who is actually responsible
The legal duty to arrange and maintain all of this sits with the owner of the property, not with a management company, a cleaner, or a letting platform. Airbnb and Booking.com do not check any of this before a listing goes live, and nothing about listing on either platform discharges the owner's responsibility.
Where a management company arranges certificates on the owner's behalf, that is a service being provided, not a transfer of legal responsibility. If a certificate lapses because nobody chased the renewal, the consequences sit with the property owner, whatever the management agreement says about who was meant to book it. It is worth knowing exactly what your management contract covers here, in writing, rather than assuming it is handled.
What to actually do
Keep a simple record of what certificate is valid until when, for gas, electrical and anything else specific to the property, and renew each one before it lapses rather than after. Have alarms tested at every changeover as a standing instruction to whoever cleans the property. And treat fire safety as something to look at properly once, walking the flat as a guest who has never been there before would, rather than assuming a smoke alarm and a fire blanket are the whole job.

This is general information about safety obligations that typically apply to rented property in England, not legal advice. Requirements can vary by property type and change over time. Confirm the current requirements with a qualified engineer or electrician, and check your specific obligations with your local council or a solicitor before letting a property short-term.
