Frequently asked questions

+Does surplus plasterboard count for PAS 2035?

Yes when spec and certification are preserved. Keep batch numbers and BBA certificates with your evidence pack.

+How do I transport plasterboard?

Flat on a pallet, kept dry. A Transit fits ~15 sheets flat.

+Can I use surplus on ECO4-funded work?

Yes — ECO4 assessors care about spec and installation quality, not new-vs-surplus provenance.
