Heat alarm requirements UK
Updated: October 2026
The heat alarm requirements UK split as soon as you name a nation. A kitchen heat alarm is a duty in every Scottish home, and a duty in a Northern Ireland private tenancy. The England landlord regulations and the Wales fitness regulations cited here do not name one. This page follows those official texts. It is not a basket of alarms. Prices and scores stay on the [heat detector comparison](/hub/fire-protection/heat-detector). The Products Compared editorial team used legislation.gov.uk, GOV.UK, the Scottish Government and the Department for Communities. We did not invent a fine. A qualifying purchase can earn a commission at no extra cost to you.

Scotland
From February 2022, the Scottish Government's fire and smoke alarm guidance applies to every home. You need a smoke alarm in the living room, a smoke alarm in every hall and landing, and a heat alarm in the kitchen. They are ceiling mounted and interlinked. Sealed long-life lithium, or mains with a battery backup, is the power the guidance accepts.
A standalone FireAngel, WISUALARM, X-Sense or AEGISLINK does not, on the listings in our comparison, link to anything. A ten-year cell meets the battery half and fails the interlink half. In this set the rows that state a link are BLACK+DECKER only. An open-plan room that includes a kitchen needs a heat alarm within 7.5 metres of any point. Sensor choice is in heat alarm vs smoke alarm.
Northern Ireland private tenancies
Private landlords in Northern Ireland have a kitchen heat alarm duty that owner-occupiers do not pick up from the same regulations. The regulations define a heat alarm as a thermistor set to respond above 58°C, and they require it in every kitchen, interlinked with the smoke alarms. Power is hard-wired or a sealed battery. A loose "10-year" title that does not say sealed is not the sealed-battery limb.
That 58°C definition is not a UK-wide trip point, and a Class A1 band is not unlawful in Scotland or England. A sealed standalone from our comparison still fails the interlink limb. Hard-wired means an electrician, the same practical stop as on the mains Kidde and the mains BLACK+DECKER.
England
English private landlords have a real alarm duty, and it is not a kitchen heat alarm. The Smoke and Carbon Monoxide Alarm (England) Regulations 2015, as amended, are explained in the GOV.UK booklet for landlords. Regulation 4 requires a smoke alarm on each storey used as living accommodation, and a carbon monoxide alarm for a fixed combustion appliance other than a gas cooker. The booklet does not add a heat alarm in the kitchen.
A gas cooker is outside that carbon monoxide limb. If you are an owner-occupier in England, this landlord duty is not your statutory heat-alarm obligation. A sealed kitchen heat alarm is a product choice, not a fine.
Wales, and the British Standard beside the statute
Wales regulation 5, in the Renting Homes (Fitness for Human Habitation) (Wales) Regulations 2022, requires a smoke alarm on each storey, mains-powered and linked so that when one sounds the others do. It also requires carbon monoxide alarms for gas, oil or solid fuel, including gas cooking appliances, unlike the England exception for gas cookers. The regulation does not name a heat alarm.
A trade page that recommends a kitchen heat alarm is recommending practice, not quoting regulation 5. Do not tell a landlord they are in breach solely because the kitchen has no heat alarm. BS 5839-6:2019 sits beside the statutes as a code of practice. Use it when a designer has specified LD2, and use the statute when the question is "must I".
Match the duty, then buy
Match the duty you actually have, then buy. Where the statute asks for interlink, a sealed standalone does not finish the job, and in this set a stated link stays inside BLACK+DECKER. The checklist after that answer is the heat alarm buying guide. What this comparison sells is on best heat alarm.
Common questions
Is a heat alarm legally required in a Scottish kitchen?
Yes, in every home, from February 2022, under the Scottish Government's fire and smoke alarm standard. The kitchen gets a heat alarm, the living room and the circulation spaces get smoke alarms, and the alarms are interlinked and ceiling mounted. Heat alarms should conform to BS 5446-2.
Does a standalone 10-year battery alarm satisfy Scotland?
Not on its own. Scottish guidance allows a sealed long-life lithium alarm, or mains with backup, and it also requires interlink. A sealed FireAngel or X-Sense with no link on the listing meets the cell idea and misses the system. A user-replaceable PP3 is not the battery-only option in that guidance.
Do private landlords in Northern Ireland have to fit one?
Yes. Private tenancies need an interlinked heat alarm in every kitchen, hard-wired or with a sealed battery. New tenancies were in scope from 1 September 2024, and existing tenancies had to comply by 1 December 2024. Owner-occupiers are outside this private-tenancy duty.
Must an English landlord fit a kitchen heat alarm under the 2022 regulations?
The England regulations, as explained in the GOV.UK landlord booklet, require a smoke alarm on each living storey and a carbon monoxide alarm for a fixed combustion appliance other than a gas cooker. They do not name a heat alarm. An English landlord is not failing those regulations merely because the kitchen has no heat detector.
Do the Wales fitness regulations require a heat alarm?
Regulation 5 does not name a heat alarm. It requires mains smoke alarms on each storey, linked to the other mains smoke alarms, and carbon monoxide alarms for gas, oil or solid fuel, including gas cooking appliances. A trade page that recommends a kitchen heat alarm is recommending practice, not quoting regulation 5.
What does Building Regulations Part B ask for in a new English house?
The Approved Document B FAQ treats Grade D2, Category LD3 as adequate for fire detection and alarm in new dwellinghouses. LD3 is an escape-route category. It is not a sentence that says every new kitchen must have a heat alarm. A designer can still specify a higher category under BS 5839-6, including a kitchen heat alarm for LD2.
Where does BS 5839-6 sit if it is not the statute?
It is the British Standard code of practice for fire detection in homes, not the England landlord regulations and not the Wales fitness regulations. Use the code when you are choosing a system grade. Use the statute when you are asking what a landlord must do in that nation.
