Winter 2021 Domestic HVO Trial

Simply complete the form below with your heating systems details. We can then assess suitability to join the trial. Photos are a great way for our Heating Engineers  to understand your heating set up better, so please upload images of your boiler and fuel tank  if you can. 

If you would prefer to complete the form on the phone with a Certas Energy Team member, please email to arrange a call at a convenient time.
