At home we are are part of a district heating system that has a heat pump and solar thermal both getting the commercial rhi, the former for just over a year now.  We were selected for a 'random' audit of the heat pump system by OFGEM with a couple of weeks notice.

They sent in an external firm of renewable energy consultants.  The man was here an hour and a bit.  He took lots of photos and seemed particularly focussed on the metering as apparently they believe there have been 'issues' with early installed systems.  He had done some homework beforehand and was aware of my system schematic diagram that was submitted as part of the rhi application.  Items he checked included:
- meters fitted correctly (in the return lines in my case)
- meter seals
- meter serial numbers
- system for recording the readings (a spreadsheet)
- knowing how to recognise meter error messages
- knowing when meter batteries require replacing
- knowing when meter re-calibration needed

Overall it went well as far as I was concerned and they have since paid me another wadge of money.  In a way I am glad we have been audited as I suspect there are not many small domestic district heating systems like ours around.

Had a 'completion' email from OFGEM today: no non-conformities no observations.  Good news.

Digressing a little, the OFGEM RHI quarterly report issued today mentions RHI audits, metering changes when external piping is involved and biomass air quality requirements.
