Can anyone post a list of the basic requirements to achieve a D rating?
Places of worship are excluded from being required to have an EPC (for the main purposes of needing an EPC in the first place - outside FiTs), but that doesn't necessarily mean that they won't need one just to claim higher FiTs rates. There is an exemption from the EPC 'D' condition for those buildings where it can be proved that it is impossible to obtain an EPC. How you do this I don't know yet, but I would guess you would need to provide a statement to that effect from one, or maybe more, DEAs.
How on earth are you going to be able to cover overheads, most of which are generated as a result of the ridiculous bodies - MCS, NICEIC, REAL and now DEA certificates when "sales" are going to need to be below the cost of the materials?
