When do you need a commercial gas engineer?

When is a commercial gas engineer required?

If you have a boiler or gas appliance with an output greater than 70kW, or one deemed by the manufacturer to be commercial, you will require a commercial gas engineer to maintain it. 

What if I have a domestic boiler in a commercial building?

Where a domestic gas appliance is fitted in a commercial building, it’s the appliance classification that matters. For instance, if a stand-alone domestic boiler is installed in a factory, an engineer only needs a domestic gas registration to work on it. However, where multiple domestic appliances with a combined output of over 70kW are fitted in the same room – for example, two 40kW boilers cascaded together, it becomes a plant room. And as such, the gas engineer will need to be registered to work on both commercial and domestic appliances.

What size of gas meter requires a commercial gas engineer?
