Does a landlord need a gas safety certificate?
Yes. If you let a property with gas appliances, the Gas Safety (Installation and Use) Regulations 1998 require you to have them and their flues checked every 12 months by a Gas Safe registered engineer, keep the record for two years, and give each tenant a copy, within 28 days of the check, or before a new tenant moves in.

If you let a property with gas, the short answer is yes, and the longer answer is a set of deadlines that repeat every year for as long as you're a landlord. Here's what the law requires, which properties it covers, and how landlords actually stay on top of it.
What exactly does the law require?
Six things, all from the Gas Safety (Installation and Use) Regulations 1998:
- Have every gas appliance and flue you're responsible for checked for safety every 12 months.
- Use a Gas Safe registered engineer, always check their ID card and that they're registered for the appliance type.
- Give existing tenants 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.
- Maintain pipework, appliances and flues in a safe condition throughout the tenancy.
The deadlines don't pause for a busy diary or a booked-up engineer. The one recognised difficulty is access: if a tenant won't let the engineer in, you're expected to take and record all reasonable steps to get the check done, which our access guide covers in detail.
Which properties and appliances does the duty cover?
Most residential lettings. The trigger is renting out a property under a lease or licence shorter than seven years, which sweeps in assured shorthold tenancies, room lets, houses in multiple occupation and rented holiday accommodation. It applies to gas the landlord provides; a tenant's own appliance is usually their responsibility, though the connecting installation and flue often remain the landlord's. If you're unsure who's responsible for a specific appliance, your engineer can advise, and it's better recorded than assumed.
Do HMOs and holiday lets follow the same rules?
The same core duty, yes. An HMO needs every landlord-provided appliance and flue checked every 12 months like any other let; what changes is the wrapping, because larger HMOs are licensed and a current gas safety record is a standard licensing condition, so a lapse there is two problems rather than one. Holiday accommodation is squarely inside the duties too. HSE lists rented holiday accommodation, chalets, cottages, flats, caravans and narrow boats on inland waterways among it, and a cottage that turns over guests weekly needs its annual check exactly as a 12-month tenancy does. Short stays don't dilute the duty; they just make the quiet season the sensible time to book the renewal.
Who arranges the check, landlord or agent?
The landlord, by default. Instructing a letting agent doesn't move the legal duty unless the management contract clearly transfers it, and HSE says that where an agent does take the duty on, the same obligations that apply to a landlord apply to the agent. Full management usually includes booking the checks and holding the records, but “usually” is doing a lot of work in that sentence. Get who does what in writing, and ask to see the records rather than assuming the work happened.
What happens if you don't comply?
Failing to arrange checks or maintain gas safely is a criminal offence carrying fines and, in serious cases, imprisonment. Enforcement grew teeth in 2026: under the Renters' Rights Act, civil penalties for breaches run 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 from May 2026, every possession case now runs on grounds you must evidence, which puts your own compliance record under the light. An out-of-date record can also complicate insurance claims and HMO licensing.
What does the annual check cost?
Less than almost anything else on the compliance list. A single-appliance CP12 typically costs about £60 to £90, with the UK average near £80; London and the South East run dearer, and each extra appliance adds a little more. Two habits keep the number down. Bundle the check with the boiler service, since the engineer is already there with the panels off, and book inside the early window rather than paying whatever the last available engineer charges in a deadline panic. Set that against the penalty figures above and the check is the cheapest line on the whole spreadsheet.
How do you stay compliant year after year?
Work from the next-due date
Track when the next check is due for each property, not when the last one happened. That one number is the compliance position.
Book inside the early window
The check can be done any time from 10 months after the last one without moving your anniversary date. Book early in that window and access problems have room to be solved.
Deliver copies, with proof
Existing tenants within 28 days, new tenants before move-in. Keep evidence of delivery, because that's what a dispute or a penalty notice will test.
File where you can find it
Two years is the legal minimum for keeping records; the life of the property is the sensible target. A record you can't produce might as well not exist.
A missed renewal is rarely carelessness; it's usually a spreadsheet nobody opened in March. Manifold tracks every property's next-due date and chases each renewal automatically, and the landlord portal keeps every certificate findable in seconds, so a request from a solicitor or council is a thirty-second job rather than a search through three inboxes.
Only a Gas Safe registered engineer can carry out the check and issue a valid record; no landlord, agent or template can. This guide is general information on how the duties work, not legal advice on a specific tenancy.
