Gas Safe Registered Engineers | A Consumer Guide
QUICK GUIDE SUMMARY
Gas Safe registered engineers hold separate qualifications for different types of gas appliances...
Gas Safe engineers hold separate qualifications for different types of gas work. It is not enough that they are gas safe registered, they must be registered to work on your type of gas appliance. So before you pick someone, you need to check they are competent for the type of gas work you would like carried out. For example, an engineer might be qualified to work on your boiler but not your cooker. We breakdown the gas safe qualification and guide you on who can do what. We also give some helpful advice on when you do not need a gas safe registered engineer to work on your heating system.
HOW TO USE THIS GUIDE
Use this Guide to make sure your gas engineer is appropriately qualified for the work you want carried out
|Category of work/appliance||Scope of qualification|
|Gas Installation pipework (upto 35mm)||Core gas safety knowledge held by all gas safe registered engineers. It is unlikely this qualification is held in isolation as there is almost nothing the engineer can work on aside from the gas pipe and even then they cannot connect onto a boiler or commission it.|
|Gas boiler (includes back boilers, combi boilers, heating only and system boilers, storage heaters and instantaneous water heaters)||Qualified to work on all aspects of your domestic gas boiler - installation, dis-connection, commission, service, repair and safety checking.|
|Gas water heaters||This qualification is included with an engineer's Gas Boiler competency (above). However if held in isolation, the engineer is only qualified to work on your domestic, instantaneous gas water heater. A water heater will only provide hot water. It is a wall hung unit and looks like a boiler - not to be confused with a hot water cylinder.|
|Cookers and hobs (excludes range cookers)||Qualified to work on all aspects of your gas cooker - installation, dis-connection, commission, service, repair and safety checking.|
|Fire/space heater (includes gas fires, wall heaters, convector heaters, gas stoves and flueless gas fires)||Qualified to work on all aspects of your domestic gas fire - installation, dis-connection, commission, service, repair and safety checking.|
|Warm Air (blown heating systems)||Qualified to work on all aspects of your gas fired ducted warm air heaters - installation, dis-connection, commission, service, repair and safety checking.|
|Range cookers (including range gas cooker/boilers)||Qualified to work on all aspects of your gas fired range cooker and range cooker boiler - installation, dis-connection, commission, service, repair and safety checking.|
|Comb Analysis (Combustion Analysis)||This qualification is now a mandatory part of an engineer's core qualifcation. It is required to test the combustion peformance on any gas fired appliance when commissioning following an installation, re-commissioning, after servicing or replacing parts.|
|Category of work/appliance||Scope of qualification|
|LPG appliances (Liquid Petroleum Gas - or Bottled Gas)||Seperately qualifed in LPG for each of the above appliances|
|Pressurised Water G3 for unvented hot water cylinders||Qualified for the installation, servicing, commissioning and maintenance of unvented hot water systems|
|Vented hot water storage||Standard cylinders and most engineers are now qualified as part of their core training.|
|Caravans (including static homes, touring and park homes)||Bottled gas appliance that still require an engineer to be seperately listed in this category of accomodation.|
2. Find and check on-line by postcode:
You can search the gas safe register by postcode to find a local installer. NB The default is set to look for a ‘mains gas’ company, but you can filter to LPG to narrow your search.
You can check a business is registered:
Enter their ID number or company name. NB if do not have the company ID number, sometimes it’s hard to find them by name. Companies frequently change their trading name or list their limited company name which is different to their trading name. You may need to go back to the postcode search to find them that way.
Check an individual engineer:
If you have their licence number, found on their ID card, you can enter it in this section. If you do not have their licence number, but they work for a company, you will be able to find them under the company listing, either by the company registration number, company name or via their postcode. If they do not work for a company, they can be hard to find without the licence number. You will likely have to ring the Gas Safe Register customer services line.
Check an individual’s qualifications on line:
One you find an individual engineer, either via the licence number or under the ‘View our Engineers’ button on the company listing, you can check the qualifications of the engineer. Example below:
Advice by job type – do you definitely need a gas safe engineer?
Not all heating jobs need a gas safe registered engineer. Many can be undertaken by a qualified plumber. NB hot water qualifications are held by gas engineers and plumbers. The table below sets out common heating and plumbing jobs and when you need a gas safe registered engineer to attend.
