Gas safety certificate reminder for UK landlords

A gas safety certificate reminder warns you before the landlord gas safety record (often called a CP12) reaches its typical 12-month anniversary. Upload the PDF to Certs Reminder, confirm the dates, and get emails at 30, 7 and 1 day. There is no informal grace period on the legal check.

If the property has gas appliances, fittings or flues you provide for tenants, the annual check is one of the dates landlords cannot afford to keep only in email.

  • 30 / 7 / 1 day email alerts before the 12-month anniversary
  • Notice if the record has already lapsed
  • Track EICR and EPC in the same account

  • Separating gas dates from EICR and EPC clocks

What a CP12 is

CP12 is a common name for the landlord gas safety record issued after a check by a Gas Safe registered engineer. The legal requirement is the annual check and record — not the nickname. Keep the PDF; do not rely on a calendar note without the document.

The 12-month renewal cycle

HSE guidance on the Gas Safety (Installation and Use) Regulations 1998 is that landlords must keep relevant gas appliances, fittings and flues safe, arrange a check at least every 12 months by a Gas Safe registered engineer, keep the record, and give tenants a copy on the stated timetable.

You can often arrange the check up to two months early and keep the original anniversary. That is not extra time after expiry. There is no informal grace period once the 12 months have passed.

Why reminder timing is 30 / 7 / 1 day

A reminder is only useful if it leaves time to book the engineer. Certs Reminder emails at 30 days (the booking window), then 7 and 1 day if the first alert was ignored. If the date has already passed, you still get a notice — that does not make an overdue check lawful.

How to use Certs Reminder for gas safety

Upload the latest record. Confirm the issue and expiry dates we extract. When the new check is done, upload the new PDF the same day so the next 12-month clock is correct.

Northern Ireland has its own gas safety regulations. Confirm nidirect / HSENI guidance if the property is there — do not assume Great Britain wording applies unchanged.

Frequently asked questions

What is a CP12?

CP12 is a common name for the landlord gas safety record. The legal requirement is the annual check and record, not the nickname.

Is there a grace period after 12 months?

HSE guidance does not describe an informal grace period. Treat the anniversary as the deadline and book before it.

When should I book the engineer?

The 30-day email is the booking window. You can often check up to two months early and keep the original anniversary — that is not extra time after expiry.

Does a letting agent remove the landlord’s gas safety duty?

HSE guidance is that using an agent does not remove the landlord’s responsibility for the duties being met. Put who books the check in the contract, and still track the date.
