Gas Appliance Testing

Kiwa Ltd has been approved by BEIS as a Notified Body for the Gas Appliance Regulation. In preparation for this new legislation, our gas test engineers are advising manufacturers and suppliers on any changes they may need to achieve compliance. 

Our engineers can advise on compliance with any of these Directives:

  • The Gas Appliance Directive (GAD - applies to almost all gas-fired appliances except some industrial applications, and in April 2018 will become the Gas Appliance Regulation (GAR). There are significant differences between the GAD and the new GAR, for example relating to risk assessments and meeting the 'state of the art' condition. For advice on the GAR, please contact or call our gas laboratory (01242 677877). 
  • The Boiler Efficiency Directive (BED) -  applies to all domestic boilers (up to 70kW)
  • The Low Voltage Directive (LVD) - applies to all gas-fired appliances carrying electrical components or controls
  • The Electromagnetic Compatibility Directive (EMC) - again, applies to all gas fired appliances containing electronics
  • The ErP (Energy Related Products) Directive. In addition to the efficiency data confirmed under the BED/GAD, the ERP will also require proof of tapping cycles

We provide gas appliance testing for:

Fires & stoves   Heaters [radiant, overhead, patio, tabletop]   Cookers   BBQs   Boilers   mCHP Camping equipment     Water Heaters   Catering equipment   Fuel cell mCHP   Sterling engine mCHP  Fuel Cell Systems   Specialist Items

Our engineers can test gas appliance components in isolation, or as part of the appliance - pipes & fittings, valves, burners, manifolds, fans, flue terminals and switches. 

Where no standard exists, we can carry out a risk assessment or create a meaningful performance assessment method for your gas appliance.

 We are also able to help you with approvals for North America. However, we always stress that this can be a complicated and costly set of approvals.

Gas appliances are designed to operate with gas of a specific composition. The composition varies between countries. This 'Wobbe card shows the composition range for European countries. And here is our popular Gas Comparison card which contains useful information about hydrogen, methane, town gas and LPG.

As well as gas appliance testing, we also provide audit and product surveillance services, including assistance with establishing quality management procedures. Kiwa Gastec also operates in the fields of Hydrogen, Biomass and other energy technologies.

"The service for our gas testing has been excellent. James and Shoki are very approachable and helpful."

Why Kiwa?

Since the early 90s we have been operating a gas appliance testing laboratory and now test the majority of gas fires, a significant proportion of gas boilers and a wide range of other gas-fired appliances on behalf of manufacturers and Trading Standards Officers and other governmental bodies.
Whilst we always apply the highest technical rigour to all that we do, indeed our UKAS accreditation demands this, we pride ourselves on bringing client-focus and confidentiality to all stages of your product's development towards full compliance and commercialisation.
Many manufacturers benefit from our pre-test capabilities and, increasingly, involve us in early development stage testing. This is of particular benefit for emerging technologies where new standards are constantly being developed.
