I am running a GSHP that was installed in 2011. I have a SAP calculation that was used for planning but the actual property is more efficient than the SAP calculation. I fitted the HP, better U value windows and also more insulation than it specified.
My technology qualifies and the installer was MCS registered.
So what do I need now to claim?
EPC or final as built SAP calculation or even a GDA? The air test is costing £200 plus VAT but do I need it to qualify?

Thanks All.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12197&Focus=203622#Comment_203622 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12197&Focus=203622#Comment_203622 Fri, 13 Jun 2014 14:59:48 +0100 ted If so, you only need an EPC (needs to be less than 2 years old).
If not, you need a GDA.

If you get the GDA then you will need to implement any loft or cavity wall insulation recommendations it contains.

Have you checked that the make/model of GSHP is on the OFGEM eligible product list for the period? Being MCS accredited is not enough - see https://www.ofgem.gov.uk/publications-and-updates/domestic-renewable-heat-incentive-product-eligibility-list]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12197&Focus=203624#Comment_203624 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12197&Focus=203624#Comment_203624 Fri, 13 Jun 2014 15:03:55 +0100 ted
“eligible new-build property” means a property which is supplied with heat by a plant in
respect of which an accreditation application is made and where—
(a) any building that forms part of that property was built principally with the use of the
labour or resources of the first owner (including where the resource was a loan which the
first owner was liable to repay);
(b) the date the property was first occupied was after the date the plant was first
commissioned; and
(c) the property has not, while the building was built or at any subsequent time been owned
wholly or partly by a person who is not an individual;]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12197&Focus=203627#Comment_203627 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12197&Focus=203627#Comment_203627 Fri, 13 Jun 2014 15:17:22 +0100 gustyturbine
Thanks for your input. Yes it was a self-build. A local energy consultant told me that I would need my final as built SAP calculation. I guess I will need anyway to be signed off by my BCO so would this be a way of avoiding an EPC or would they not accept an as built SAP?

Yes my HP is a Worcester Bosch Greenstore so it does qualify luckily.

Thanks again Ted.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12197&Focus=204320#Comment_204320 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12197&Focus=204320#Comment_204320 Wed, 25 Jun 2014 09:28:18 +0100 Sprocket
We live on a farm (not a working farm, just a hobby farm).
We live in the farmhouse. Heated by oil. No mains gas available on site.

The farm includes a couple of old barns that we restored in 2010-2012. An almost ground-up restoration from derelict this includes loads of insulation, dense UFH, good air tightness, MVHR, PV, and each building has a GSHP (a 4kW and a 12kW).

They are restored as an extension of our living accommodation at the farm. They are not joined to the main farmhouse but one of the new barns is "knocked through" into an adjoining building (an earlier conversion/restoration) that has domestic office space heated by oil.

Does either or both of these barns qualify for RHI?
I can't see any reason why not looking at the RHI requirements but maybe I am missing something?]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12197&Focus=204324#Comment_204324 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=12197&Focus=204324#Comment_204324 Wed, 25 Jun 2014 10:16:44 +0100 ted
"If you are not supplying heat to multiple eligible properties, but have one domestic property which is comprised of multiple buildings – for example, a main house and outlying buildings - you may not be eligible for the Domestic RHI. If your heating system provides heat to more than one building, or to one building and an outdoor swimming pool, you should contact us to discuss your application. We will assess each application for a property of this nature on a case by case basis. To contact us, please email us."
