Surplus PIR Insulation for Renovation Projects in Portsmouth: 2026 Guide
Renovating a Portsmouth property? Matching materials is often the difference between a scheme that reads authentic and one that jars. In 2026, surplus and reclaimed PIR insulation is easier to source across South East than any time in the last decade.
Sourcing strategy for Portsmouth renovations
- Sample first — take a piece of existing PIR insulation to the yard
- Order 10% overage for cuts, breakages and matching future repairs
- Prioritise weathered face for exteriors, quarry face for repairs
- Confirm delivery slots against your trades' schedule
Portsmouth renovation pricing
| Grade | Typical price | Notes |
|---|---|---|
| Job-lot / bulk | £8.00 per m² | Merchant clearance, palletised |
| Standard graded | £18.00 per m² | Sorted, ready-to-fit stock |
| Heritage / premium | £28 per m² | Character grade, hand-picked |
Common PIR insulation matching pitfalls
- 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
Collection and delivery inside Portsmouth
Most Portsmouth sellers hold stock inside PO1, PO4 and PO5 and offer South Coast next-day £55–£90. For loads over a tonne of PIR insulation, a hiab drop is usually more economical than multiple van runs.
