If your house was built in 2007 then it should have had foil-backed

Is that 'should' a 'should' or a 'must'? The document isn't clear on that point.

Note also that even if it were a 'must' then if that requirement only came in around 2006/2007 then it still might not apply to a 2007-built house if that house was built against plans agreed before 2006.

Is this
a house built by one of the large national builders, or a small
local outfit ?.

Persimmon.... (Enough said! ;-))

Thanks everyone for the comments; I'll keep an eye on things and so what happens.
