Help and advice please.
I have had planning permission for extension above an existing garage.
I have been approached by an ``energy efficiency company'' saying that I must have a SAP test done on the new extension to prove that it is energy effeicient. The quote was for £200 and that I must have this to pass Bregs.
My understanding was that if I could prove the u values for the insulation on the new extension that this would be enough. Insulation companies have said that they would provide u value calcs. Any ideas.
Thanks in advance.
