Surplus Plasterboard UK: Job Lots and Off-Cuts at 60% Off Merchant
Plasterboard is bulky, heavy and easily damaged — which is exactly why it dominates skip volume on UK sites. Every job leaves 5–10 sheets over. Multiply by 200,000 active sites and you get a huge secondary market.

- Full pallets (48 sheets) unlock the best £/sheet
Frequently asked questions
+How long does surplus plasterboard last stored dry?
Indefinitely if truly dry. Any humidity above 65% degrades the paper facing within 12 months.
+Can I use surplus fireboard on a party wall?
Only if the batch label is intact and you can prove the fire rating. Building Control will ask.
