Carbon comparison
Reclaimed sash windows carries close to zero embodied carbon vs new manufacture. On a Derby refurb, choosing reclaimed can offset 3–8 tonnes of CO₂e per property depending on scope.
Planning acceptance in Derby
Derby planning officers routinely accept and often require matching reclaimed stock inside conservation areas across East Midlands.
Embodied carbon: Reclaimed Sash Windows in Derby vs new
Choosing surplus or reclaimed sash windows in Derby avoids the A1–A3 manufacturing emissions of newly produced stock. On a typical Derby project this equates to roughly 26–52 kgCO₂e per window — material evidence under Part Z, RICS WLCA and BREEAM Mat 06.
East Midlands 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 sash windows purchase inside DE1, DE22 and DE23 builds an audit trail that stands up to WLCA review.
- A1–A3 avoided: ~26–52 kgCO₂e per window
- A4 (transport): actual mileage from the Derby 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 Midlands 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: Derby yards are quieter and forklift drivers have time, so you avoid the DE1, DE22 and DE23 weekday delivery crush.
- Ask for the yard's "just arrived" list — the best sash windows 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 Derby
Reclaimed materials from private sellers are typically zero-rated for VAT. Surplus stock from VAT-registered East Midlands 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 sash windows packaging for retrofit and Part L evidence
- Log the Derby postcode of the source yard against the project record
