Fire Risk Assessments for Landlords: Which Lets Need One
Updated September 2026 · England and Wales
Short answer: it depends on what you let. A whole house or flat let to one household does not need a fire risk assessment, but it does need working smoke and carbon monoxide alarms. HMOs, holiday lets and Airbnbs, and any shared parts of a building (including flats above shops) do need one. A holiday let needs one even if you only let it for a single night, and that is the duty most landlords miss.
Landlords get told all sorts of things about fire safety: by letting agents, insurers, electricians and management companies. Some of it is right, some is out of date, and some is a sales pitch. The rules themselves are not complicated once you know which box your property falls into.
This guide sorts it by type of let, with the official sources linked, real questions from landlords and hosts, and cases where things went wrong.
Does your let need a fire risk assessment?
| What you let | Fire risk assessment? | Who is responsible | What else applies |
|---|---|---|---|
| Whole house to one household (England) | No | You, the landlord | Smoke alarm on every storey, CO alarm where there’s a fixed combustion appliance, fire hazards under the Housing Act, furniture fire safety rules if furnished |
| Flat in a block or converted house | Not for the flat itself | The freeholder or managing agent assesses the common parts and all flat front doors | Alarm rules inside the flat. If the lease makes you responsible for your front door, you have duties for it too |
| HMO (3+ people, 2+ households) | Yes | You, the landlord or manager | HMO licensing and management regulations. See our HMO guide |
| Holiday let, Airbnb or serviced accommodation | Yes | The owner, letting agent or whoever controls the property | Government guidance expects interlinked, mains-powered smoke and heat alarms |
| Flat above a shop or other mixed use | Yes, for shared parts | Whoever controls the shared parts and escape routes | Plus the alarm rules for the flat itself |
| Whole house or flat to one household (Wales) | No | You, the landlord | Mains-powered, interlinked smoke alarm on every storey, and CO alarms, or the home is legally unfit |
Based on the Regulatory Reform (Fire Safety) Order 2005, article 6, which excludes private homes but covers the common parts and flat entrance doors of buildings with two or more homes, and any property let to paying guests.
Letting to one household: what you need instead
A home let to a single household counts as domestic premises, so the Fire Safety Order doesn’t apply and you don’t need a fire risk assessment. You still have firm legal duties.
- Smoke alarms: since 1 October 2022, at least one on every storey with a room used as living accommodation, working at the start of each tenancy.
- Carbon monoxide alarms: in any room with a fixed combustion appliance, such as a gas boiler or wood burner. Gas cookers are excluded.
- Repairs: if a tenant reports a faulty alarm, you must repair or replace it as soon as reasonably practicable. Councils can fine up to £5,000 per breach.
- Fire hazards: fire is one of the hazards councils assess under the Housing Act 2004, so a dangerous layout or missing escape route can still be enforced against.
- Furnished lets: sofas, mattresses and other upholstered furniture must meet the furniture fire safety regulations.
Coming up: the Renters’ Rights Act 2025 changes came into force on 1 May 2026, with a private rented sector database and ombudsman due from late 2026. A new Decent Homes Standard for private lets, which includes keeping fire alarms and fire safety equipment in repair, is due by 2035.
“I’m getting an electrician in for a repair and he’s told me that hard wired fire alarms are now mandatory.”

In England, they aren’t. Battery alarms that work meet the legal minimum for a single let, unless an HMO licence condition says otherwise. In Wales it is different: since December 2023, every rented home must have mains-powered, interlinked smoke alarms on every storey. Know which country’s rules you’re under before you pay for an upgrade you don’t need, or skip one you do.
Letting a flat in a block: who covers what
If you own a leasehold flat and let it out, the fire risk assessment for the building is not your job. It belongs to the freeholder or managing agent, and since the Fire Safety Act 2021 it has to cover the structure, the external walls, the common parts and every flat entrance door, including yours.
The front door is where landlords get caught. If your lease makes you responsible for repairing it, the Fire Safety Order treats you as having control of it to that extent. So a door that fails the building’s assessment can land on you, not just the freeholder. Check the lease, keep the door in good order, and don’t swap it for a non-fire-rated door when you refurbish. Our blocks of flats guide covers the building-side duties in full.
Holiday lets and Airbnb: the one most landlords miss
A property let to paying guests is not a private home in the eyes of fire law. The government’s guidance is blunt:
“The law (FSO) applies to you if you are charging someone to stay in your property as a guest and it is not being occupied as a private dwelling, even if it is just for one night.” From Making your small paying guest accommodation safe from fire, Home Office, updated January 2025.
That means a written fire risk assessment, recorded in full. The government guide is aimed at smaller properties: a ground floor, or ground and first floor, sleeping up to 10 people with no more than four bedrooms upstairs. It also covers single flats. For those, it expects:
- Interlinked detection: smoke and heat alarms that all sound together, mains-powered with a battery backup. Radio-interlinked alarms are allowed. Sealed long-life battery alarms may be accepted as a short-term measure, for around two to three years.
- A protected way out: doors that will hold back smoke for long enough to escape, which in many homes means upgrading rather than replacing them.
- Clear information for guests: what to do if the alarm sounds, and how to get out.
If your let has three or more storeys, more than four bedrooms upstairs or an open-plan layout, you’re outside the simple guide and should expect to need a professional assessment. Running a B&B or guest house rather than a self-catering let? See our hotels, guest houses and B&Bs guide.
“I somewhat naively thought it would be reasonable and achievable actions”
Holiday let host reacting to the October 2023 changes, Airbnb Community, October 2023
Another host in the same thread estimated “a £2000 cost” to comply. That is realistic for a small let that needs interlinked alarms and some door work, and it is far less than the prosecutions below. The replies also cleared up two myths: radio-interlinked alarms are acceptable, and you don’t always need certified fire doors.
“I did a risk assessment on my 1750 cottage which said I needed to replace my historic doors with fire safety ones.”
Owner of a period holiday cottage, Airbnb Community, February 2024
Replacement is rarely the only option, especially in older or listed properties. A good assessor will look at upgrading existing solid doors, and at whether better detection and a clear escape route reduce what the doors need to do. If a report goes straight to “replace everything”, ask why.
Registration is coming too. Wales opens its visitor accommodation register on 1 October 2026, and hosts must register by 31 March 2027. In England, a national short-term lets register has been promised for 2027.
Flats above shops
If you let a flat above a shop, restaurant or office, the shared entrance, stairs and any escape route that passes the commercial unit are covered by the Fire Safety Order. The biggest issue we see discussed is detection: if the shop and the flat have separate alarm systems, a fire in the shop at night may not wake anyone upstairs. One expert on a fire safety forum put it plainly when a landlord bought a shop with two flats above: separate systems weren’t adequate, and the alarm needed to reach the flats. The commercial tenant and the landlord have to co-ordinate, so agree in writing who does what.
Cases involving ordinary landlords and hosts
Two patterns stand out. Holiday let prosecutions are common and costly, because fire services inspect them as businesses. And in the smaller cases, legal costs often dwarf the fine itself.

Five checks every landlord should make this year
- Work out which box you’re in. Use the table at the top. If you let the same property both as a holiday let and to tenants, the holiday let rules apply while guests are paying to stay.
- Test every alarm at the start of each tenancy or booking, and keep a dated record. It is the cheapest evidence you’ll ever have.
- Read your lease if you let a flat. Find out who owns the front door before a management company letter arrives.
- Don’t let a tradesperson set the standard. If an electrician or door supplier says something is “now mandatory”, ask which regulation, and check it.
- Review after changes. Adding a bedroom, converting a loft or switching to short lets changes your duties. The Perranporth holiday let owner prosecuted in 2021 had added bedrooms without reviewing fire safety.
What a typical holiday let assessment looks like
Example
The property: a three-bedroom cottage on two floors, let as a holiday home sleeping six. It sits inside the government’s small paying guest guide, so the owner could do it themselves, but they want a professional report for their insurer.
The visit: under an hour. The assessor checks the alarms, the bedroom doors, the route down the stairs and out, the kitchen, and the fire information left for guests.
What usually comes up: smoke alarms that run on batteries and aren’t linked to each other, no heat alarm in the kitchen, and no fire instructions in the guest information. Replacing the alarms with interlinked mains alarms is the main cost.
Cost: around £150 to £300 for a house of this size.

Landlord fire risk assessments: quick answers
Do landlords need a fire risk assessment?
Only for some types of let. HMOs, holiday and short-term lets, and the shared parts of buildings such as flats above shops need one. A house or flat let to a single household does not, but it must have the required smoke and carbon monoxide alarms.
Does an Airbnb need a fire risk assessment?
Yes. Government guidance says the Fire Safety Order applies if you charge someone to stay as a guest, even for one night. You must carry out a fire risk assessment and record it in writing.
Who is responsible for the front door of a let flat?
The freeholder or managing agent must include all flat entrance doors in the building’s fire risk assessment. If your lease makes you responsible for repairing your front door, you share responsibility for it to that extent.
Do smoke alarms in a rented house have to be hard-wired?
Not in England for a single let: working battery alarms on every storey meet the legal minimum. In Wales, rented homes must have mains-powered, interlinked smoke alarms on every storey. HMO licences and holiday let guidance often expect mains-powered interlinked alarms too.
What is the fine for not having smoke alarms in a rental?
In England, councils can issue civil penalties of up to £5,000 per breach under the smoke and carbon monoxide alarm regulations. Serious cases can be prosecuted under the Housing Act or health and safety law.
Can I do the fire risk assessment for my holiday let myself?
For a small, simple property, yes, if you follow the government’s paying guest guidance carefully and record it. For larger lets, three or more storeys, open-plan layouts or anything outside the guide, a professional assessment is the safer choice.
How much does a fire risk assessment for a holiday let cost?
Typically £75 to £200 for a flat or small cottage and £150 to £300 for a house with up to four bedrooms, based on our survey of published UK prices.
