Landlord gas safety: the complete duty

If you let a home with gas in it, the duty comes down to one annual check, one record and a short list of dates. Everything below is the whole of it, with the regulation behind each part and a link to the guide that goes further. The rules are in regulation 36 of the Gas Safety (Installation and Use) Regulations 1998, which extends to England, Wales and Scotland, so a Northern Ireland letting sits outside what is set out here.

What are a landlord's gas safety duties, exactly?

There are eleven of them, and nearly every one has a date attached. The table gives each duty, what it means on a real property, when it bites and where it comes from. The regulation numbers are regulation 36 and regulation 36A of the 1998 regulations, and the HSE references are that regulator's own landlord guidance.

Which lettings and which landlords does this cover?

Almost every residential letting held on a lease of under seven years or on a licence. HSE lists premises rented out by local authorities, housing associations, private sector landlords, housing co-operatives and hostels. It also lists rooms let in bedsit accommodation, private households, bed and breakfast accommodation and hotels, and rented holiday accommodation such as chalets, cottages, flats, caravans and narrow boats on inland waterways. Leases longer than seven years are generally outside the duty, though accommodation that comes with a job usually carries it through an implied tenancy. Where an agent manages the property, HSE expects the management contract to specify who makes the arrangements, and an agent who takes that on picks up the same duties the landlord has; a vague contract leaves them with the landlord.

What does the annual check involve?

The engineer works through every appliance and flue you are responsible for and records each one as safe or not. Regulation 36(9) sets the floor by pointing at regulation 26(9): the effectiveness of any flue, the supply of combustion air, the appliance's operating pressure or heat input (or, where examining those is not reasonably practicable, its combustion performance), and its operation, so as to ensure it functions safely. Around that sit the checks the job needs to make those four possible, including a gas tightness test, a look at ventilation and at the safety devices, and a walk round the property against the appliance list, because an appliance missing from the record was never checked. A safety check is not a service: the manufacturer's service schedule is separate work, and many landlords book the two together for the same visit.

What does the record show, and how do you read it?

Regulation 36(3)(c) fixes the contents, so every valid record carries the same nine things: the date of the check, the address of the premises, the name and address of the landlord or agent, a description and location of each appliance and flue checked, any safety defect identified, any remedial action taken, confirmation that the check met regulation 26(9), and the name, signature and registration number of the individual who carried it out. Two of those decide whether the record does its job. Every gas appliance in the property has to appear, and anything shown as a defect needs a remedial action against it. One quirk is worth knowing: the copy given to a new tenant may leave the signature off, as long as it states where a signed copy can be inspected.

What does a gas safety check cost, and who pays?

Checkatrade's published cost guide, last updated June 2026, puts a single-appliance gas safety certificate at £60 to £90 with a UK average of around £80, and additional gas appliances at roughly £10 to £15 each. London and the South East run dearer than that. Quote from the appliance list rather than the postcode, since appliance count moves the price more than anything else, and a wasted visit for no access often carries its own charge. The bill is the landlord's. The duty sits on the landlord under regulation 36, and regulation 36(10) means nothing agreed with a tenant shifts it.

What happens if the check does not get done?

It is a criminal offence, and HSE says so in plain words: a landlord who breaks these regulations is putting lives at risk and breaking the law, HSE gives gas safety a high priority and will take the appropriate action to ensure compliance, and that could result in a substantial fine or a custodial sentence. The Renters' Rights Act's civil penalties (up to £7,000 for initial or minor non-compliance, up to £40,000 or prosecution for serious, persistent or repeat cases) attach to breaches of that Act itself, not to the gas safety regulations. Councils ask for the current record when licensing an HMO, and with Section 21 gone in England, a possession claim puts the landlord's own compliance under a light.

What if the tenant will not let the engineer in?

You cannot force entry, and you are not expected to. You are expected to take all reasonable steps, and HSE describes those as leaving a notice saying you tried to gain access, writing to explain that the check is a legal requirement, and being able to show at least three attempts to complete it. HSE also says the approach has to suit each set of circumstances, and that it would ultimately be for a court to decide whether what you did was reasonable. Keep every letter, message and missed appointment on file, because that trail is the whole of your defence if the record lapses. Access is the one thing a tenant can do that counts towards your compliance, which is regulation 36(10) read the other way round.

Do you need carbon monoxide alarms as well?

Yes, and the rule is different in each nation. In England, since 1 October 2022 a carbon monoxide alarm is required in any room used as living accommodation that contains a fixed combustion appliance, with gas cookers excepted, and an alarm found faulty after a tenant reports it must be repaired or replaced. Scotland has required one since 1 February 2022 in any room with a carbon-fuelled appliance such as a boiler, open fire or wood burner, in every home rather than only in rentals, and gas cookers and hobs are excluded there too. Wales requires an alarm in each room containing a gas, oil-fired or solid fuel appliance under the Renting Homes fitness rules that applied to all occupation contracts from 1 December 2022, and there is no cooker exception, so an identical kitchen can carry a duty in Cardiff that it does not in Carlisle.

What does the year look like, step by step?

Where do landlords most often slip up?

• The inherited certificate. A property bought mid-year arrives with a record nobody diarised, and the first anyone thinks of it is after the date has passed. Every acquisition should get a next-due date on day one.
• The tenant-change assumption. A new tenancy doesn't reset the 12 months; the incoming tenant needs a copy of the current record before move-in, so a lapsed record is a problem to fix before the keys change hands.
• The vague management contract. “Fully managed” means different things to different agents, and the legal duty stays with the landlord unless the contract clearly moves it. Agree who books and who files, in writing.
• Access left too late. The properties that lapse are the hard-to-enter ones chased a fortnight before the deadline. Start those at month 10, in writing, and keep every attempt on file.
• The missing appliance. The old fire in the spare room counts. If an appliance isn't on the record, it wasn't checked, so walk the property against the list once a year.

Which guide answers your question?

The landlord cluster is one guide per question. The table gives the question, the guide that owns it and the answer in a line, and the links underneath go straight there.

How do you keep a whole portfolio compliant?

Track one number per property, the next-due date, and let something tireless watch it. The hardest part of gas safety for a landlord isn't the check, it's never missing a renewal across many properties, each on its own anniversary. Manifold tracks every property's renewal automatically and chases it, and the landlord portal keeps every certificate findable in seconds, so compliance stops depending on whoever last opened the spreadsheet, and “can you send me the current record” is answered before it's asked.
