Reclaimed vs New Surplus PIR Insulation in Milton Keynes: 2026 Comparison
Should you buy new or reclaimed PIR insulation for your Milton Keynes project? In 2026 the answer increasingly leans reclaimed — cost, planning acceptance and embodied carbon all favour it. Here's the head-to-head for South East buyers.

Quality and spec differences
- Kingspan Kooltherm, Celotex GA4000, Recticel Eurothane — factory-fresh over-orders

- 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 Milton Keynes refurb, choosing reclaimed can offset 3–8 tonnes of CO₂e per property depending on scope.
Planning acceptance in Milton Keynes
Milton Keynes planning officers routinely accept and often require matching reclaimed stock inside conservation areas across South East.
Frequently asked questions
+Is reclaimed always cheaper than new in Milton Keynes?
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.
