How to determine home energy rating

[JayS]

wookey, Thanks for that, at least its a start, but still only 50mm, they would'nt get out of bed for that here. 

Well, you can use one of these then, goes up to 100mm insulation. http://www.encon.co.uk/products/view/229/kingspan-kooltherm-k18-dry-lining-board-51n

And since it's phenolic, it'll correspond to roughly 200mm (depending on the type of polystyren) of polystyren.

Thick enough?

JayS, thanks for that, now your talking.

Looks expensive though?
Do you think i can just stick it on with my, Knuaf Mk3 adhesive. ?

What "qualification" do you need, in order to issue an Energy Performance Certificate? There's a lot of people here who would be more than able to do one for their own house if required to for FiTs / Grants etc - but presumably they'd need to be 'trained' or accredited by paying membership money to someone or other

You need to be an accredited Domestic Energy Assessor to issue an EPC (the certificates get logged on a central database - all very similar to MCS).  About £1K for a 2 day training course and exam is the cheapest I've seen. An EPC on a property can be obtained for £30 upwards.

Separately there will be Green Deal Advisors - but I think the two will merge at some point in the near future. But how many of the existing 14,000 or so DEAs who will feel obliged to pay for that 'privilege' remains to be seen. Most already feel pretty hard done by due to changing government regs and massive (400%) over supply in the marketplace.

St-ruff its downhill.

Just pay a wadge and get returns.

Ivan, Ted, if i paid you a wadge what would you do? 

Perhaps i could achieve, a "certificate of stark raving bonkers ability".
