Thank you both for rapid and helpful replies. @JohnMo "Things to watch out for" - meaning these would exempt me from grant? What's the relevance of the buffer?

Hi all Great resource - I have enjoyed reading these forums over the past few weeks and have learned a lot. First post so please be patient (I've used the search function!) We are planning a renovation and have got to the point where we are settled on converting from oil combi/rads to UFH downstairs fed by ASHP. Will be some solar PV as well. I've had "help" from a few firms who plan and install greener heating systems and are MCS certified so will "save" me £7500 using the BUS. The trouble is their prices are super inflated, often justified by over-speccing. I can source all the kit I need more economically, and our chosen builders will be able to fit (not savvy enough / not enough time to do DIY), What are peoples' experiences with / approaches to getting the BUS grant in this situation? Choose an MCS-certified contractor to acquire the kit from my chosen sources at zero VAT, then pay them back, pay the labour and claim the grant? Suspect it's not that simple. Thanks for any advice you can offer. Tim
