A gas safety certificate usually means the Landlord Gas Safety Record, often called a CP12. It records the findings of a gas safety check. Landlords have annual checking and record-sharing duties; someone simply owning and living in their home does not automatically have the same landlord duty. Servicing, safety checks and the resulting paperwork serve different purposes.
Do homeowners need a gas safety certificate?
The main legal guidance below concerns domestic rented accommodation in England, Scotland and Wales. Northern Ireland has separate legislation; use the HSENI guidance linked in the references for properties there.

For owner-occupiers, HSE strongly recommends regular maintenance and at least annual servicing of gas appliances by a suitably qualified Gas Safe registered engineer. Treat this safety recommendation separately from a landlord's legal record obligations.
If you are changing how the property is used, review the duties before someone moves in. A previous arrangement for your own home may no longer cover what is needed.
How often is a landlord gas safety check needed?
Landlords must arrange an annual safety check of the relevant gas appliances and flues. Give existing tenants their copy within 28 days of the check, and new tenants a copy before they move in. Keep records for at least two years.
HSE explains a conditional early-check arrangement: checks completed up to two months before the deadline can preserve the existing annual date. If relying on this flexibility, retain the evidence needed to demonstrate compliance, including the record until two further checks have been completed.
Discuss access early with the occupier. Keep written appointment communications and seek appropriate advice if access cannot be agreed; do not force entry.
What should you look for on the record?
Check the property and landlord or agent details, inspection date, appliances and flues listed, and the engineer's name, registration number and signature. The record must also identify safety defects and remedial action, and confirm the required safety examinations.
Read the appliance list carefully. Ask the engineer to explain any omission, limitation or finding rather than assuming that “gas safety certificate” means every item in the building was assessed.
Check ownership where tenants have their own appliances. HSE distinguishes those appliances from landlord-provided equipment, while responsibilities for associated installation and pipework may remain with the landlord.
Save a readable copy with subsequent repair records. If contact details, appliance descriptions or the property address look wrong, ask the issuing engineer to check them.
Is a gas safety check the same as a boiler service?
No. HSE says not to assume a service includes every required safety-check item, or that an annual safety check provides effective maintenance by itself. If you want both during one visit, request both explicitly and confirm the records you will receive.
A boiler-only appointment also does not automatically cover a landlord-provided gas cooker or fire. List all relevant appliances when booking so the engineer can confirm the scope and qualifications required.
Our guide to boiler servicing frequency explains the maintenance timetable. For budgeting that separate task, see what affects boiler servicing costs.
How should you prepare for the appointment?
- Describe the property: explain whether it is your own home, rented accommodation or a home with lodgers.
- List the appliances: include their locations and any shared or communal arrangements.
- Provide previous records: share the last check, known defects and evidence of completed repairs.
- Arrange safe access: clear ordinary obstructions without removing appliance covers or altering fittings.
- Confirm the price and scope: ask about appliance numbers, servicing, repairs, return visits and applicable VAT.
Check the attending engineer's Gas Safe ID card and the relevant work categories. A business name on an invoice is not a substitute for checking the person doing the work.
When booking, say whether you need a landlord record, homeowner check, service or a combination. Clear instructions help avoid paying for an appointment that does not cover your intended task.
What happens if the engineer finds a defect?
The completed safety-check record should report the findings even when faults are identified. It should not be withheld until repairs are finished. Landlords must address defects promptly and prevent use of an unsafe appliance until it has been made safe.
Ask the engineer to explain the finding, any restrictions on use and the next action. Keep follow-up documentation with the original record. Do not reconnect or restart equipment that has been made safe or marked not to use.
For arranging the check and its documentation, see our gas safety certificates service. Describe any known issue when booking so the appointment can be scoped appropriately.
