When should I have my green deal assessment for RHI?

Posted by Cathy Debenham on 19 May 2014 at 8:59 am

Q: I am installing an air source heat pump (ASHP) later this year, and will be applying for the domestic renewable heat incentive (RHI). Do I need to have the green deal assessment BEFORE the system is commissioned to be eligible for the RHI? And secondly, does the green deal advice report have include an ASHP as one of the possible measures?

A: I'll answer your second question first, as it's the easiest. You are eligible to apply for the domestic RHI for an air source heat pump whether it is recommended on a green deal advice report or not. It doesn't matter. If you live somewhere that has access to mains gas, it may not be a recommended measure. It also may not be more efficient than a gas boiler in either cost or carbon terms, but you can still go ahead.

When you get your green deal assessment (GDA) is up to you. As long as you have it before you apply for the RHI it is OK. Some people get it first, as it may make useful suggestions of other ways you can save energy while you have the disruption of installing a new heating system.

If you think it will recommend loft or cavity wall insulation, then it will save you some money if you install the insulation before you get the GDA. This is because if those measures are recommended, you then have to get an updated EPC to prove that you've done it when you apply for the RHI.
