An agreed check of gas appliances and flues
Gas Safety Certificate (CP12)
Set out which gas appliances and flues need checking and what record you need for the property.
WHAT IT INVOLVES
Know what you’re asking for.
A gas safety check and a boiler service have different purposes. A safety check produces a record of the checks and findings; servicing concerns maintenance of the appliance. Include both in your requirements if you need both. Appliance numbers, access and the type of installation help define the work before a tailored quote can be confirmed.
What to discuss in the scope
- A defined list of gas appliances and associated flues to be checked.
- Safety checks within the agreed scope by an appropriately registered gas engineer.
- A record identifying the checks completed and any findings requiring attention.
Before the visit
- List gas appliances, including boilers, fires and cookers, and say who owns them.
- Have any previous gas safety record and appliance documents available.
- Explain access arrangements, including appliances or flues in shared or locked areas.
Worth knowing
A boiler service, repairs and additional investigation are not assumed to be included. The appliance scope, price and engineer availability must be confirmed. This preview is not an emergency response service.

Your questions, answered.
Is a boiler service included?
Only if it is specified in the agreed quote. A gas safety record and appliance maintenance are separate parts of the work.
What details are useful for a quote?
Include the property type, appliance count, any shared installations and whether you also want servicing. Mention known faults without attempting repairs yourself.
