@morgan pretty poor. Although with the GHG having ended, I doubt they are in a rush

@batalto - when you say waiting RHI, what do you mean?  I filled my RHI request on-line and pressed go. And the response came back approved in seconds. Set up my bank account payment and boom. All done. 
Our first payment due now

@julianc because of the Green Homes Grant the documents need to be reviewed. I had to submit paid invoices to show how much I paid towards the system and how much the GHG covered. As an FYI my cost was £10,340 and the GHG picked up £5k of that for me. This reduces the RHI by the same amount (£5k)

@julianc they said it would be up to 10 days. From what I've seen it'll be quicker

As a note - RHI approved. £219 a quarter for the next 7 years, inflation linked at CPI - more than covers my costs

Good news @batalto  Is your ASHP fully funded by GHB and RHI?

I have received my first quarterly RHI payment of £357

@julianc It will be yes. 

£10,000 for the whole system

£5,000 GHG

£6,132 RHI (plus inflation)

£11,132 total from the government for the system

Be interesting to see what happens if the government go ahead as planned and replace the RHI in March next year with an upfront grant of up to  £4,000.

£11,132 vs £4,000 is quite a big difference.

I assume the current RHI is probably unaffordable for the government as the number of installations ramp up.

@jeff seems to me like the GHG is just being replaced with a grant £4k less and the RHI is being scrapped. My cost profile would totally change and probably make the ASHP not worth it - unless the price of electricity changes to a much lower base. As is I'll make money and my cost should also reduce due to my solar and batteries
