Where to Sell Leftover Building Materials in the UK

Every UK build over-orders by 8–15%. Historically that surplus went to skip, family or the back of the van. In 2026, a live secondary market prices it: pallets of unused PIR fetch £180–£320, half-pallets of bricks £90–£140, boxes of tile adhesive £5–£8 each. Listing takes under three minutes.

What sells fastest

  • PIR insulation — under 48 hours on average
  • Facing bricks (any colour) — under 72 hours
  • Sheet timber (OSB, ply) — 3–5 days
  • Roof tiles matched to common profiles — 5–7 days
  • Bathroom suites still in original packaging — 7–14 days

How to price for a fast sale

The 60% rule: price at 60% of merchant new for A-grade surplus, 40% for opened/damaged, and 25% for reclaimed with visible wear. Underpricing wastes money; overpricing means a slow burn.

Photos that convert

  • Shoot outdoors, cloudy day, no flash
  • Include a tape measure or brick for scale
  • Photograph any damage honestly — buyers appreciate it
  • Show the pallet label / batch number if intact
