Wasn't there a "works before FENSA" date exemption somewhere around 2004

April 2002, which is exactly why I replaced my windows in February 2002
(and put central heating in). However, very few window installers were
signed up until a long time after that date anyway. I spoke to mine
probably some 6 months later, and he was just starting to think about
it.

I did however make my systems all conform to Part L except for the K
glass, which is a complete waste of money. IIRC, the payback for K
glass was something like 50 years, and that didn't take into account the
extra lighting needed because of the slightly darker glass. That money
went towards a condensing boiler and extra insulation, which was a very
much more effective use of it.
