Performance guarantees, measuring what works, and EPC reform, with Steven Heath (Knauf Insulation)

This week we're speaking with Steven Heath, technical director at Knauf Insulation (UK and Ireland) and a really interesting and experienced person in the sector.

So while we had him, we ran through a bunch of our favourite hoary subjects: measuring performance, performance guarantees, and what we think about EPCs.

Knauf is a firm that's done some really interesting work in all of these areas and has even managed to make headway with the UK state in getting them to think about the value of testing performance, with EPCs and whatever SHDF is called now (the state-driven money tap for decarbonising social housing).
