The rules for residential installations are different from commercial systems
This page details the differences for household systems which become eligible in RHI 'Phase 2'
The RHI scheme does not apply to domestic systems until 2013
But some households can in the interim claim the Renewable Heat Premium Payment, and will still be eligible for the RHI, when it does start to apply.
Following the delay to the non-domestic scheme, DECC re-evaluated the timing for the domestic phase (originally projected April 2012). The next promise was that there would be a consultation by the end of 2011, with implementation October 2012 alongside the Green Deal. However the timetable was delayed again in March 2012, where three further consultation stages were proposed before the domestic phase of the RHI could start - now in summer 2013.
What is a domestic system?
The government has said:
By domestic installations, we mean installations where a renewable heating installation serves a single private residential dwelling only. This does not include multiple residential dwellings served by one renewable heating installation (e.g. district heating) nor residential dwellings which have been significantly adapted for non-residential use. For example, a house where someone works or runs a business from home would be considered domestic, whereas a house converted to be a shop or bed & breakfast would be considered non-domestic and could receive RHI support. This means that if a company, private landlord or registered social landlord installs single renewable heating units, in one or multiple residential dwellings, this would constitute a domestic installation and they will not be able to receive RHI tariffs from the outset, but will be able to claim from 2012.
What will the household RHI scheme be like?
We don't know! The launch announcement contained little information about residential installations.
Maybe they will stick to the principles of the original consultation (but maybe they won't...)
