What do the ID categories mean?

Follow our guide to the back of the Gas Safe ID card

Looking for an engineer to undertake gas work? It’s tempting to pick the first name on the list – but you might want to investigate further before you do.

Gas Safe registration is a legal requirement for anyone carrying out gas work, but there are many different types of gas work a business may offer. All engineers need to hold a ‘core’ element to their qualifications – once they have this they can then add in any additional types of work they wish to offer.

For more information on the different categories that engineers will hold to carry out work on certain appliances and a glossary of terms commonly used to refer to gas work, you can consult our guide.

Domestic work categories Commercial work categories

 

If you're unsure what would be classified as domestic and commercial work then our definitions below may help...


Domestic
Relates to those gas appliances that are designed for use in a domestic property, as well as gas pipework up to 35mm in diameter, again in domestic property.

Note:
There may be instances in larger domestic properties where non-domestic appliances and larger pipework maybe required. In these cases appropriate non-domestic work categories may be necessary.

Commercial
In the context of work categories and competence, this refers to the size of pipework, appliance type/gas consumption in addition to the property type. However, the property type is not the sole criteria. For example, a ‘domestic’ gas boiler installed in a church may in certain circumstances still be considered a ‘domestic’ appliance regardless of being installed in a ‘non domestic’ property.

Often appropriate competence can only be determined on a case by case basis. If in doubt, contact us to check.
