The non-domestic renewable heat incentive has been helping early adopters see a return on their investment in renewable energy for the last eight years. It is due to close to new entrants in March 2021 and there is currently no plan to replace it. So it seems a little strange that Ofgem are now, at this stage, demanding planning permission for ground source heat pumps to be eligible for the subsidy.

isoenergy helps its clients with the RHI application and can also help with the requirements from the Local Authority. We have been successful with several retrospective applications although it is best practice to gain the relevant permissions before commencing with any renewable projects.

The current application process is already complex, putting off many who do not want the paperwork or the hassle. Isoenergy can make this process easier as we understand what is required and have experience helping other clients apply.

The latest requirement set out for the application of non-domestic RHI is that they must have either proof of planning permission being granted, a certificate of lawful development or correspondence from the local planning authority stating that planning permission for the heat pump is not required.

The good news is that we have never had an application for a heat pump system turned down by a local planning department. Given the AONB’s, SSSI and listed or conservation areas we work in, this bodes well for future projects too.

In short, it is now crucial that you have evidence that the local planning authority have been informed of your intentions to install a ground source heat pump if you want to apply for the non-domestic RHI.
