Compliance
The landlord's mid-year gas-safety review: a 15-minute audit
By Jordan Valentine-Dunn, Gas Safe registered engineer · 9 July 2026
A mid-year gas-safety review takes about 15 minutes. List every let property, check each one's next-due date rather than the date of the last check, confirm your tenants have their latest gas safety record, and book anything due in the next couple of months before engineers' autumn diaries fill up.
Why do it in the middle of the year
Renewal dates drift, and the reminder you're relying on is often the letting agent's, the engineer's, or your own memory, none of which is foolproof. Catching anything due before the autumn rush gives you slack: the landlords who wait until the month it's due are the ones who find every local engineer booked solid in October.
The 15-minute audit
List every property with a gas appliance
Anything you let that has a boiler, fire, hob or other gas appliance you're responsible for.
Check the next-due date, not the last check
For each property, what date is the record due to be renewed? That is the number to track, not when the last check happened.
Confirm the tenant has their copy
Existing tenants are owed the latest record within 28 days of each check; a new tenant must have it before they move in.
Book what's due in the next two months
Anything due before the autumn, get it in the diary now, and batch nearby properties into one trip.
Put the records where you can find them
You must keep them for at least two years. Store them somewhere searchable so you can prove compliance in seconds, not hunt through a drawer.
What to check on each property
- Is the gas safety record still in date, with the next-due date noted?
- Has the current tenant actually received their copy?
- Was any remedial work from the last check completed and evidenced?
- Are the carbon monoxide alarms working, and air vents clear and unblocked?
- Has the boiler been serviced, separately from the safety check, if you offer that?
One quirk worth using: you can bring a check forward by up to two months, from 10 months after the last one, and keep your original renewal date. So if a review turns up something due in September, an August check keeps your anniversary exactly where it was rather than dragging it earlier.
This is general guidance, not legal advice for a particular tenancy. The check itself must be carried out by a Gas Safe registered engineer, who is the only person who can issue a valid gas safety record.
