How often must a landlord arrange a gas safety check?

Regulation 36(3) of the Gas Safety (Installation and Use) Regulations 1998 requires a gas safety check of every relevant gas appliance and flue at least every 12 months, carried out by a Gas Safe registered engineer.

Can I get the check done early without losing my anniversary date?

Yes. A check carried out up to two calendar months before the 12-month deadline keeps the original anniversary date, so you do not shorten future cycles. The tool flags when you have entered this two-month early window.

How long must I keep gas safety records?

You must keep a record of each safety check for at least two years under Regulation 36(6). You must also give existing tenants a copy within 28 days of the check, and new tenants a copy before they occupy.

Do I have to check appliances the tenant owns?

The landlord's duty covers the appliances and flues you provide. Where appliances belong to the tenant, you are not responsible for them, but you remain responsible for the installation pipework you provide that connects them.

Do these rules apply to holiday and short-term lets?

Yes. Short-term and holiday lets are relevant premises under the regulations, so the same annual check, record-keeping, and safe-condition duties apply just as they do to a standard residential tenancy.

UK landlords carry specific legal duties for the gas appliances they provide, set out in Regulation 36 of the Gas Safety (Installation and Use) Regulations 1998. This checker works out which duties apply to your situation and, if you supply a date, whether your next annual check is on track.

How it works

The tool first decides whether the landlord duties apply at all — they apply when you let relevant premises that contain gas appliances, pipework, or flues that you have provided. When they do, it lists the core obligations and calculates your next due date:

next check due = date of last check + 12 months
early window   = next due − 2 months   (book here to keep the anniversary)
overdue        = today is past the next-due date → breach of Reg 36(3)

The core duties under Regulation 36 are:

Annual safety check by a Gas Safe registered engineer on every gas appliance and flue you provide.
Keep the gas safety record for at least two years from the date of each check.
Give tenants a copy of the gas safety record within 28 days of the check. New tenants must receive a copy before they occupy.
Maintain appliances and flues in a safe condition between checks — not just at the annual inspection.

The two-month early window — why it matters

You can book the annual check up to two calendar months before the 12-month deadline and the anniversary date carries forward, not the actual check date. This prevents a slow drift toward an overdue situation in busy letting portfolios.

For example, if your last check was on 1 March 2024 (due by 1 March 2025), you can book from 1 January 2025 onward. If the engineer visits on 15 January 2025, the next annual check is still due by 1 March 2026 — not 15 January 2026.

The tool flags when you enter this early-window period so you know you can book without losing your anniversary.

Who is responsible for what

Item	Landlord’s responsibility?
Appliances you provided (boiler, hobs, fires)	Yes
Flues and installation pipework you provided	Yes
Appliances the tenant brought themselves	No — but the pipework serving them remains your responsibility
Communal gas meter and supply to the property	Usually the gas distributor / supplier, not the landlord

Penalties for non-compliance

Failure to carry out the annual gas safety check is a criminal offence under the Gas Safety (Installation and Use) Regulations 1998. The Health and Safety Executive (HSE) can prosecute landlords who fail to comply, and local authorities also have enforcement powers. Beyond the legal consequences, an unchecked appliance poses real risks of carbon monoxide poisoning or gas explosion.

This tool provides general guidance, not legal advice. If you are unsure about your specific obligations, consult the HSE’s landlord guidance or seek professional advice. Always use a Gas Safe registered engineer — verify their registration at the Gas Safe Register website.
