A CP9 is a visual risk assessment of a gas appliance the engineer has not worked on. IGEM/G/11 sets out three situations for one: an appliance met while working on another, an appliance forming part of a tightness test, and an appliance relit after purging following work elsewhere. It records the visible condition, any signs of deterioration, and a risk classification. It does not say an appliance is safe to use.

Frequently asked questions about CP9

When is a visual risk assessment used?
When an engineer comes across a gas appliance they are not working on. IGEM/G/11 Appendix 5 gives three cases: an appliance in the same place as the one being worked on, an appliance on an installation that has just been tightness tested, and an appliance relit after the installation was purged following work elsewhere. It is not a substitute for a full safety check.
Does a CP9 replace a CP12 for landlords?
No. A CP9 does not satisfy the landlord gas safety check requirement under GSIUR 1998 Regulation 36. If an appliance cannot be fully inspected, the engineer should record the CP9 assessment and advise the landlord to arrange access for a complete check as soon as possible.
