The Engineer Signed It, But Does the Law Accept It? Auditing Your Landlord Gas Safety Record Line by Line

Every landlord knows the routine: the engineer visits, runs through the appliances, hands over a folded sheet of paper or a PDF, and the file is considered complete. Yet tribunal decisions and possession hearings across England and Wales tell a less comfortable story. Gas safety records are among the most frequently defective documents in rental portfolios — not because landlords skip the check, but because the paperwork that follows it is incomplete, misdated or simply does not satisfy the regulations.

Under the Gas Safety (Installation and Use) Regulations 1998, the record is not a formality. It is a statutory document, and courts treat it as such. A tenancy served with a defective record can find its Section 21 route blocked, exactly as if no check had been carried out at all.

What the Law Actually Requires

A compliant Landlord Gas Safety Record must contain, as a minimum:

• The date the check was performed (not merely the date of issue)
• The address of the property at which the appliances were inspected
• The name and signature of the engineer, together with their Gas Safe registration number
• Identification of each appliance and flue checked, with the results of each inspection
• Any defects identified and the action taken or recommended
• Confirmation of the landlord's and tenant's names where applicable

The checks must be carried out by an engineer registered on the Gas Safe Register — not merely 'someone qualified', and not a plumber who let their registration lapse. An engineer who is registered but whose membership expired the week before the visit has, in the eyes of the law, produced no record at all.

The 28-Day Rule and the 12-Month Rule

Two timeframes govern the record, and confusing them is the single most common error landlords make.

The 12-month rule. A check must be carried out at intervals of no more than twelve months. This is not a rolling anniversary of the tenancy; it runs from the date of the last check itself. A record dated 14 March 2024 is valid until 14 March 2025 — not until the end of the month, and not until the tenant's renewal date.

The 28-day rule. For an existing tenancy, a new record must be provided to the tenant within 28 days of the check being completed. For a new tenancy, the record must be given to the tenant before they move in — there is no grace period, no 'it's in the post' allowance.

A landlord who arranges the check on time but takes six weeks to forward the paperwork has technically breached the regulations. Retention of proof of issue — a dated email, an acknowledgement, a signed receipt — matters as much as the record itself.

Common Defects That Surface in Possession Proceedings

Housing solicitors report recurring patterns in defective records:

• Date ambiguity. The record shows only an issue date, with the inspection date left blank or implied. Courts require the actual date of the check.
• Missing registration numbers. A signature alone is insufficient; the Gas Safe number must appear on the record.
• Partial appliance coverage. A boiler is checked but the gas hob or a flue is omitted. The record must cover every gas appliance and flue in the property, including tenant-owned appliances connected to the landlord's pipework.
• Address discrepancies. A record for 'Flat B' where the tenancy references '2A' invites dispute over whether the document relates to the let at all.
• Backdating or carry-over. Some engineers note a 'due date' twelve months ahead that quietly becomes treated as the expiry date, when in fact the check is due on the anniversary of the inspection itself.

A Pre-File Audit Checklist

Before filing a gas safety record, verify each of the following:

1. Inspection date is clearly stated and within the last twelve months
2. Engineer's Gas Safe registration number appears on the document
3. Registration was valid on the date of inspection (check the Gas Safe Register website if in doubt)
4. Full property address matches the tenancy agreement
5. Every gas appliance and flue is listed with individual results
6. Engineer's signature is present
7. Dated proof exists that the record was issued to the tenant within 28 days (or before occupation for a new let)
8. A copy is retained for the statutory period alongside your other compliance documents

If any line fails, arrange a corrected record before the tenancy begins or the notice is served. A reissued record is a minor inconvenience; a struck-out possession claim is not.

The Wider File

The gas safety record does not stand alone. Tribunals increasingly examine the entire compliance file — EPC, deposit protection, Right to Rent evidence, electrical safety reports — and a weak gas record undermines confidence in the rest. Treat the document as a legal instrument, not a receipt, and audit it with the same rigour you would apply to a contract.
