This service is for manufacturers of large boilers (bigger than 500kW).

A large boiler is any oil, gas, solid fuel or biomass boiler bigger than 500kW. Testing is usually for one of three reasons:

  • We test to enable an appliance to get Clean Air Act approval so it can be used in a Smoke Control zone
  • We test for appliance owners to apply for an RHI emissions certificate
  • We test the appliance efficiency to enable the boiler to be listed on the Energy Technology List
