Landlord gas safety: the complete guide

If you let a property with gas, you have legal duties for your tenants' safety. They aren't complicated, but missing them is a criminal offence, so it pays to know exactly what's required. This is the whole picture, with links to the detail on each part.

What are your gas safety duties at a glance?

• Have every gas appliance and flue you provide checked for safety every 12 months.
• Use a Gas Safe registered engineer, and always check their ID card.
• Give each existing tenant a copy of the record within 28 days of the check.
• Give new tenants a copy before they move in.
• Keep records for at least two years.
• Keep pipework, appliances and flues maintained in a safe condition throughout the tenancy.

Who does the check, and how do you book it?

A Gas Safe registered engineer; nobody else's check counts. Check the ID card, and that the appliance types on the back cover what's in your property, because LPG and park homes carry extra competencies. Booking has a rhythm worth learning: the check can be done any time from 10 months after the last one without moving your anniversary date, so book inside that window and the date never drifts. Cost varies by area and by how many appliances there are, which is why quoting from the appliance list beats guessing; the cost guide below covers the ranges.

What happens during and after the check?

The engineer inspects and tests every appliance and flue you provide, gas tightness, burner pressure or heat input, flue performance, ventilation and safety devices, and records each one as safe or not. Then the deadlines start: existing tenants get their copy within 28 days, new tenants before they move in, and the record is kept for at least two years. If an appliance fails, the defect goes on the record, and putting it right promptly is part of your ongoing maintenance duty rather than an optional extra.

What are the penalties if it slips?

Breaches of the 1998 regulations are criminal offences, with fines and in serious cases imprisonment. Since 2026 the Renters' Rights Act adds civil penalties of up to £7,000 for a first offence and up to £40,000 for serious or repeated ones, and with Section 21 abolished in England, every possession case now examines the landlord's own compliance. Councils also require the current record when licensing an HMO. The recurring theme: a lapsed record costs far more than the check it replaced.

What sits alongside gas on the compliance list?

Two more safety regimes, in England, and both get asked for at the same moments as the gas record. The fixed electrical installation needs an EICR at least every five years under the 2020 electrical safety rules, issued by a qualified electrician; the two registrations don't overlap, so the same person almost never does both checks. And since October 2022, a carbon monoxide alarm is required in any room used as living accommodation with a fixed combustion appliance, gas cookers excepted, with alarms repaired or replaced once reported faulty. Many landlords have the alarm positions looked at during the annual gas visit while the engineer is there. Keep the EICR and alarm records in the same file as the gas paperwork, because HMO licensing, conveyancing and any dispute will want the set.

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.

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.
