- Cancelled project surplus in your postcode
- Regional trade Facebook groups
Certification you must preserve

Frequently asked questions
+Does surplus bricks count for PAS 2035?
Yes when spec and certification are preserved. Keep batch numbers and BBA certificates with your evidence pack.
+How many bricks per m² of wall?
~60 per m² for a single skin, 120 per m² for a full brick wall, allow 5% waste.
+Can I use surplus on ECO4-funded work?
Yes — ECO4 assessors care about spec and installation quality, not new-vs-surplus provenance.
