Frequently asked questions

+Does surplus slate tiles count for PAS 2035?

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

+Can I mix reclaimed sizes?

Diminishing courses are traditional — mixing sizes is often historically correct.

+Can I use surplus on ECO4-funded work?

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