Very specific laws and regulations cover the design, supply, connection, modification and servicing of mains connected as well as off-grid gas powered equipment. Where the volume of gas delivered or the size of the equipment connected exceeds a certain size (70kW of mean  heat output) the installation is deemed to be commercial and is covered by even more comprehensive regulation.

Furthermore, laws governing corporate responsibility and latest HSE practice suggest that any business with gas powered equipment should consider their installation commercial whether or not the system or equipment exceeds any threshold.  Business owners have a duty of care to ensure that their gas powered equipment and installations are properly maintained, serviced, repaired and certified with work undertaken by Gas Safe registered, appropriately qualified and certified engineers.  Landlords and their rented accommodation are also covered.

The Gas Safe engineer is accountable for ensuring that not only are they qualified to work on the installation but that their work is undertaken to the standards set out in the agreed codes of practice including with regard to recordkeeping and certification.

Commercial Gas Installations

Commercial gas installations include any gas installation on a commercial or business premises as well as any domestic installation exceeding 70kW of mean heat output.  If you are in any doubt we would recommend taking advice from a Gas Safe registered commercial gas engineer who will be able to identify which regulations cover your installation.

Gas is transported around the UK by National Grid Transco and distributed by one of eight regional gas distribution companies.  They are responsible for all pipework and faults up until the emergency cut off valve which is located immediately upstream from your meter.  The meter is owned and is the responsibility of your gas supplier whilst all installations, pipework, equipment, valves and ancillaries downstream of your meter are your responsibility.  If you are a business operating from the premises, the landlord of a commercial residential premises or a domestic property with a large gas system then your installation is considered to be commercial.

Commercial Gas Servicing

All gas installations, including both the installed appliances as well as the pipework, flues and associated ancillary systems should be regularly inspected and serviced.  These regular checks are undertaken to ensure that the system is not only working effectively, efficiently and safely but that there are no ongoing concerns that might cause a dangerous situation or unplanned shutdown in the future.

Commercial Gas Repairs

There are many reasons why a gas installation, or one of it’s component parts may suddenly fail or cease to function even if it has been regularly serviced and inspected but prompt attendance by an expert engineer, diagnosis and repair is always an urgent priority. Our commercial gas services include in excess of 100 uniformed, qualified registered commercial gas engineers who will attend promptly, diagnose the problem and resolve it quickly.

Commercial Gas Certification

All gas installations should be regularly inspected and certified.  For commercial premises’ this is not only good practice but it is also a legal requirement and quite probably a requirement of most insurance policies.  In any case, once a gas installation has been inspected the Gas Safe registered engineer is required to keep a record of their visit, the inspection and to leave a copy on the premises.  Where an installation falls short of the minimum safe standard a gas engineer would either need to rectify the shortcomings or, again as required by law, to isolate the supply until such a time as the installation could be made safe.

What To Look For In A Commercial Gas Company

Anyone or any business working on gas systems must be Gas Safe registered. A well established, reputable commercial gas company will have a corporate Gas Safe registration, that is to say the company is registered with Gas Safe, rather than simply the individual engineers who will also be registered. The business will carry a comprehensive corporate insurance policy covering public liability, third party liability and professional indemnity as well as being accredited by CHAS (health and safety) or a similar industry scheme.
