Identifying Commercial Installations

Commercial premises

Any premises occupied by staff or open to the public that contain various sizes of gas appliances must have installations, maintenance, or repair work carried out by a competent person. In most commercial settings, such as restaurants, kitchens, offices, shops, schools, or workshops, this legally requires a Gas Safe registered engineer who holds the relevant commercial qualifications. This includes professionals skilled in boiler installation and those who can act as an emergency plumber when urgent issues arise. If you are in Surrey, it's essential to hire a qualified plumber to ensure compliance and safety. 


Annual documents required include: 


CP17: This is the general Commercial Gas Safety Certificate used for most non-domestic premises and covers all types of commercial gas installations and pipework. 

CP15: This form is specifically for commercial boilers and their associated systems. 

CP16: This certificate confirms that the gas pipework has undergone strength and tightness testing. 


The occupier, owner, or person with authority for the premises (the 'responsible person') has a duty to ensure that gas fittings are maintained in a safe condition and that work is only performed by qualified individuals.

Domestic properties

Domestically used properties that feature a gas appliance combination greater than 70kw, a gas meter exceeding a U16, and gas pipework of 35mm or greater are all subject to IGEM/UP/1A regulations. It is legally required that any work performed on such installations, including boiler installation, be carried out by a commercially trained gas engineer. In case of emergencies, it’s advisable to contact an emergency plumber. For residents in need of plumbing services, a plumber in Surrey can also assist with compliance and safety.
