Reclaimed vs New Surplus PIR Insulation in Norwich: 2026 Comparison
Should you buy new or reclaimed PIR insulation for your Norwich project? In 2026 the answer increasingly leans reclaimed — cost, planning acceptance and embodied carbon all favour it. Here's the head-to-head for East of England buyers.
Cost comparison, 2026
| Grade | Reclaimed | New equivalent |
|---|---|---|
| Job-lot | £8.00 per m² | £14.40 per m² |
| Standard | £18.00 per m² | £32 per m² |
| Premium | £28 per m² | £45 per m² |
Quality and spec differences
- 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
Carbon comparison
Reclaimed PIR insulation carries close to zero embodied carbon vs new manufacture. On a Norwich refurb, choosing reclaimed can offset 3–8 tonnes of CO₂e per property depending on scope.
Planning acceptance in Norwich
Norwich planning officers routinely accept and often require matching reclaimed stock inside conservation areas across East of England.
Embodied carbon: Surplus PIR Insulation in Norwich vs new
Choosing surplus or reclaimed PIR insulation in Norwich avoids the A1–A3 manufacturing emissions of newly produced stock. On a typical Norwich project this equates to roughly 1–2 kgCO₂e per m² — material evidence under Part Z, RICS WLCA and BREEAM Mat 06.
East of England local authorities increasingly request whole-life carbon evidence on planning submissions above 1,000 m². Keeping the yard invoice, batch photos and a provenance note against every PIR insulation purchase inside NR1, NR2 and NR4 builds an audit trail that stands up to WLCA review.
- A1–A3 avoided: ~1–2 kgCO₂e per m²
- A4 (transport): actual mileage from the Norwich yard to site
- A5 (installation): identical to new — labour and fixings unchanged
- Circularity indicator: 1.0 for reclaimed, 0.7–0.9 for surplus new
Expert tips from East of England trades
- Buy the whole pallet even if you only need 80% — you'll offload the rest on SurplusBuilder inside 14 days at 60–80% of what you paid.
- Book a Friday collection slot: Norwich yards are quieter and forklift drivers have time, so you avoid the NR1, NR2 and NR4 weekday delivery crush.
- Ask for the yard's "just arrived" list — the best PIR insulation moves before it hits public listings.
- Photograph everything on the vehicle before you leave — protects both parties if a defect surfaces on unloading.
VAT, warranty and paperwork in Norwich
Reclaimed materials from private sellers are typically zero-rated for VAT. Surplus stock from VAT-registered East of England merchants carries standard 20% VAT — confirm before agreeing a price. Factory-fresh surplus retains its original manufacturer warranty when unregistered and stored correctly; keep the batch label and any BBA certificate alongside the invoice.
- Get a VAT invoice for surplus buys over £250 — it's deductible for trade
- Retain BBA / BS EN test certificates with the delivery note
- Photograph batch numbers on PIR insulation packaging for retrofit and Part L evidence
- Log the Norwich postcode of the source yard against the project record
Frequently asked questions
+Is reclaimed always cheaper than new in Norwich?
Almost always for standard grades. Premium heritage grades can approach or exceed new prices when new equivalents don't exist.
+Is surplus PIR the same spec as new?
Yes — surplus is factory-fresh, just over-ordered. Same BBA cert and lambda value.
+Does reclaimed void manufacturer warranties?
New warranties don't apply. Ex-display and surplus stock retains full warranty when unregistered.
+Is surplus PIR insulation covered by manufacturer warranty in Norwich?
Yes for factory-fresh over-orders and cancelled-order stock. The warranty runs from date of manufacture (batch label) rather than date of purchase — check the batch date before committing on large East of England orders.
+Can I count reclaimed PIR insulation towards BREEAM Mat 06?
Yes — reclaimed materials attract full circularity credits under BREEAM Mat 06 and RICS WLCA. Keep provenance photos, yard invoice and transport mileage from Norwich as evidence.
+What insurance sits behind a SurplusBuilder deal in East of England?
Verified sellers carry public liability and product-liability cover. Pallet-network deliveries insure to £1,300/pallet by default; declare higher values for premium PIR insulation loads.
