For general plumbing and heating installers or mechanical consultants we recommend anyone who is a member of the Chartered Institute of Plumbing and Heating Engineering (CIPHE) which is the professional body for the United Kingdom plumbing and heating industry. Link to their website is here

For anyone requiring gas works to install or service, then the engineer should be gas safe – please use this website to locate an engineer local to you that is qualified.

If the product is an oil-fired appliance, then the unit should be installed and serviced by an OFTEC technician. The oftec website is here

And lastly if you have an electrical installation, then we’d recommend the product should be installed and serviced by a registered member of the Electrical Contractors’ Association (ECA). Their website is here
