Carbon comparison

Reclaimed slate tiles carries close to zero embodied carbon vs new manufacture. On a Portsmouth refurb, choosing reclaimed can offset 3–8 tonnes of CO₂e per property depending on scope.

Planning acceptance in Portsmouth

Portsmouth planning officers routinely accept and often require matching reclaimed stock inside conservation areas across South East.

Embodied carbon: Reclaimed Slate Roof Tiles in Portsmouth vs new

Choosing surplus or reclaimed slate tiles in Portsmouth avoids the A1–A3 manufacturing emissions of newly produced stock. On a typical Portsmouth project this equates to roughly 4–8 kgCO₂e per m² — material evidence under Part Z, RICS WLCA and BREEAM Mat 06.

South East 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 slate tiles purchase inside PO1, PO4 and PO5 builds an audit trail that stands up to WLCA review.

  • A1–A3 avoided: ~4–8 kgCO₂e per m²
  • A4 (transport): actual mileage from the Portsmouth 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 South East 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: Portsmouth yards are quieter and forklift drivers have time, so you avoid the PO1, PO4 and PO5 weekday delivery crush.
  • Ask for the yard's "just arrived" list — the best slate tiles 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 Portsmouth

Reclaimed materials from private sellers are typically zero-rated for VAT. Surplus stock from VAT-registered South East 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 slate tiles packaging for retrofit and Part L evidence
  • Log the Portsmouth postcode of the source yard against the project record

Frequently asked questions

+Is reclaimed always cheaper than new in Portsmouth?

Almost always for standard grades. Premium heritage grades can approach or exceed new prices when new equivalents don't exist.

+How long do reclaimed slates last?

Welsh slates that have lasted 100 years typically have another 60–100 in them.

+Does reclaimed void manufacturer warranties?

New warranties don't apply. Ex-display and surplus stock retains full warranty when unregistered.

+Is surplus slate tiles covered by manufacturer warranty in Portsmouth?

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 South East orders.

+Can I count reclaimed slate tiles 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 Portsmouth as evidence.

Verified sellers carry public liability and product-liability cover. Pallet-network deliveries insure to £1,300/pallet by default; declare higher values for premium slate tiles loads.
