Is CP12 the legal name?
CP12 is an older industry label that remains widely used. The current document is usually described as a landlord gas safety record. Check that the engineer is Gas Safe registered for the work and that the record includes all the required details.
Which gas equipment is covered?
In Great Britain, the landlord must arrange annual checks for relevant gas appliances and flues the landlord owns and provides for tenants. Gas installation pipework also has to be maintained safely. If a tenant owns an appliance or the property is sublet, the HSE guidance below explains who is responsible.
When do tenants receive it?
Give each existing tenant a copy within 28 days of the check and give a new tenant a copy before they move in. Keep evidence of delivery. Keep the record for the required legal period, with any related repair paperwork.
What if the engineer finds a defect?
Take prompt action. Equipment identified as unsafe must not be used until the problem is remedied. Ask the engineer to explain the fault, any warning label and what needs to happen next. Do not remove a warning label, reconnect equipment or ask an unregistered person to carry out gas work.
Is a CP12 the same as a boiler service?
No. A landlord gas safety check covers specified safety checks. A boiler service is maintenance carried out to the manufacturer’s requirements and can involve additional work. You can often book both at the same appointment. Ask what is included and keep both records.
Does a new boiler remove the annual duty?
No. Commissioning and installation records are important, but a landlord’s continuing annual check and maintenance duties still apply where the regulations cover the property and equipment.
What if a tenant refuses access?
Contact your tenant in good time, explain the safety check and offer reasonable appointment times. Give proper notice and keep a note of each attempt to arrange access. Do not enter unlawfully. HSE explains the reasonable-steps approach; obtain legal advice where access remains blocked.
Does this apply in Northern Ireland?
Northern Ireland uses separate gas-safety law and official guidance. Landlords also have annual check, maintenance and record duties, but check nidirect or HSENI rather than relying solely on a Great Britain summary.
