How long does a gas safety certificate remain valid?
A gas safety certificate remains valid for 12 months from the date of the inspection. Landlords must arrange the next inspection within 12 months of the previous one, with the completed record kept and provided to tenants as required.
The date that matters is the expiry date shown on the gas safety record. A landlord should arrange the next inspection before that date, rather than waiting until a tenant asks for an updated document.
The inspection date can be brought forward by up to two months without changing the usual renewal date. This gives landlords a practical window for arranging access, while keeping the annual inspection cycle consistent. The engineer records the inspection date and the date by which the next check is due.
If a property is being let to a new tenant, the gas safety check must be completed before the tenancy starts. The landlord must then give the new tenant a copy of the record before they move in. For an existing tenancy, the updated record must be provided within the required period after the inspection.
Landlords should keep each gas safety record for at least two years. Keeping older records as well can help show a clear history of inspections, repairs and appliance changes, particularly when managing several properties.
A gas safety record applies to the appliances and installation checked on that visit. It is not a permanent approval for the property. If a boiler, cooker, fire or flue is replaced, altered or newly installed, the work must be checked by a Gas Safe registered engineer. The landlord may need an updated record or additional documentation for the changed installation.
The record also does not remove the need to act if a fault appears between inspections. A boiler that begins leaking, produces unusual fumes or repeatedly shuts down needs attention before the next scheduled check. The inspection date may still be current, but the new fault must not be left until renewal.
When a property changes hands, the incoming landlord should obtain the existing gas safety records and confirm when the next inspection is due. Responsibility for future checks passes to the new landlord, so relying on an incomplete handover can leave an avoidable gap in the paperwork.
We can inspect the gas appliances and flues covered by the landlord’s responsibilities, record any safety defects and provide the completed documentation. If remedial work is needed, we explain what must be done before the installation can be considered safe for use.
- Check the expiry date on the current record.
- Book the next inspection within the permitted renewal window.
- Give the completed record to the tenant in the required timeframe.
- Keep the records and evidence of any remedial work.
- Arrange an additional check after relevant gas work or an appliance change.
An in-date gas safety record doesn’t replace a boiler service. The record confirms that the appliances and flues met the required safety checks on the inspection date; it doesn’t assess efficiency or cover routine maintenance.
If the boiler is due a service before the next gas safety inspection, arrange both at the appropriate time. We can explain which work the property needs and keep the safety paperwork separate from service and repair records.
