Surplus PIR Insulation Buyer's Checklist London 2026
Every London buyer needs a consistent inspection process for PIR insulation. This 2026 checklist covers what to check, questions to ask the seller, and how to protect a payment.
Before you go
- Ring ahead — confirm the PIR insulation is still on the yard
- Ask for photos of the exact stock
- Confirm price per unit and total
- Route-plan to the London yard, factor in weight for return trip
On the yard
- Kingspan Kooltherm, Celotex GA4000, Recticel Eurothane — factory-fresh over-orders
- Full 1200×2400 boards, uncut, in original packaging
- Same lambda value (0.022 W/mK) as new merchant stock
Payment protection
- Prefer card over cash for larger buys
- Get an invoice with VAT number where applicable
- Photograph loaded vehicle before leaving
- Keep receipts against manufacturer warranty (surplus)
Collection and delivery inside London
Most London sellers hold stock inside N, E, SE and SW postcodes and offer same-day van hire from £120; hiab drops £180–£280. For loads over a tonne of PIR insulation, a hiab drop is usually more economical than multiple van runs.
Frequently asked questions
+Can I return unused PIR insulation?
Rarely at yard level. Order accurately; sell any surplus on SurplusBuilder afterwards.
+How long can PIR be stored?
Indefinitely in original wrapping, out of direct sun.
+Does SurplusBuilder mediate London disputes?
Yes — verified sellers agree to a mediation process for disputes over quality or delivery.
