Frequently Asked Questions

Is a Boiler Service the Same as a CP12?

No, a boiler service and landlord gas safety check are distinct. Servicing maintains the boiler according to its manufacturer's schedule. The safety check covers landlord gas appliances and flues, with findings recorded on the CP12. Neither automatically replaces the other.

Can I Book CP12 and Boiler Servicing Together?

Yes, we offer a CP12 and boiler service in one visit. Request both when calling and describe every landlord gas appliance, including boilers, cookers, hobs and fires. A boiler service alone does not cover safety checks on the other appliances.

How Often Is CP12 Required, and Can I Book Early?

Landlord gas appliances and flues need annual checks under regulation 36. Under regulation 36A, qualifying checks in the two months before the deadline retain that deadline. This is not a grace period afterwards. Have your previous record ready when calling.
