Gas Safety Inspection Record (CP4)

A CP4 is a gas safety inspection record used for domestic properties where a full landlord CP12 is not required. It records the results of a voluntary gas safety inspection covering appliance checks, tightness testing, and flue assessments. Homeowners, property buyers, and insurance companies use it as evidence that the gas installation has been professionally inspected.

Frequently asked questions about CP4

What is the difference between a CP4 and a CP12?
A CP12 is the legally required landlord gas safety record for rented properties under GSIUR 1998 Regulation 36. A CP4 is a voluntary gas safety inspection for homeowners or other situations where a statutory landlord check is not required. Both cover similar checks but the CP12 has specific legal obligations attached.
Should homeowners get annual gas safety checks?
While not a legal requirement for owner-occupied homes, Gas Safe and manufacturers strongly recommend annual gas safety inspections. Many home insurance policies require evidence of regular gas appliance maintenance. A CP4 provides formal documentation of this.
