RHI Timelines
We registered our ASHP with the RHI team in April - despite follow ups every fortnight, our account is still not live despite receiving an email six weeks ago from them stating that they were completing our registration.Has anyone else experienced such a long registration period?
If it takes this long to register I wonder if their payments are equally inefficient. I remember it took a while to confirm mine, and I got a lot less than my GS heat pump installer predicted I would receive. Predicted to receive 18k but RHI was only £12.5k , absolute disgrace really, was fuming at the time.

Payments have been received as promised on time though. wow. That sounds sharkish. When did you have your GSHP installed?
Is there any legal recourse you can take against the installers?
I have to say that we met a lot of installers when we were getting quotes for our ASHP and solar PV, and a large percentage did not across as professional or ethical. A bit of a minefield that we had to navigate. It was installed in 2017.No, nothing we could do because they used the word estimate.Here is the reply I received when I queried the difference
The MCS heat loss calculations we use to design the heat pump system take into account only the heat loss through the fabric of the building – no account of the heat gains from sunlight, metabolic gains (i.e. body heat) or from the appliances / lighting in the building is included, so the heat loss is relatively high. This means that the heat pump system is capable of maintaining the desired temperature in the house at the design climate, regardless of the potential prevailing conditions internally.
RHI payments are based on the energy requirement of the building as defined by an EPC, which does take additional gains into account so the result is almost always lower. In most cases the EPC figure is in the region of 25% lower, but this does vary from building to building.
Variation can be related to the type of dwelling – new build properties have to meet certain criteria to pass building regulations so variance tends to be lower than in renovation/retrofit properties, but this isn’t always the case and it may not be obvious why. Because the two assessments use different mathematical models there is always potential for an amount of disparity between the two which is not always predictable.
We have also seen considerable variation between EPCs produced for the same dwelling by different assessors. The EPC is produced using software called rdSAP, which requires the assessor to choose element types from a series of menus; there are a number of wall types, floor types etc from which the model is populated. Different choices made by assessors can have a considerable effect on the result.
On your quotation and the graph that was supplied it is noted that the calculation is an estimate, that annual payments include a presumed RPI of 2% and that the heat loss calculations used may differ to the values calculated in your EPC. We try to offer an objective and realistic estimate of the potential RHI payment your heat pump system may generate, but due to the potential variation in the models it can only be an estimate.
It's extremely naughty that they base their figures on the MCS heat demand figures and RHI is actually paid out on the EPC figure.
Can't fault our installers in any other way though. they were extremely professional throughout and have had no issues with the heating.Our property was a new build btw. Very interesting. I‘ll go through my paperwork and see how ours was drawn up. That‘s if we ever actually get registered. Our RHI was approved yesterday... finally. Did you get what you were expecting? The site is not hugely intuitive and I don’t really see how much our next will/should be. When I get some time this weekend I’ll look into it in greater detail.. Once fully set up the site is pretty good.With payment details and schedule like this

You’ve got a terrific tariff. I think ours is just over 10p. Payments on GSHPs are much better thanks ASHP.
Are you heating a large area?
