- Manufacturer over-orders (PIR, mineral wool, plasterboard)
- Cancelled project surplus in your postcode
- Regional trade Facebook groups
Certification you must preserve

Collection and delivery inside Coventry
Most Coventry sellers hold stock inside CV1, CV3 and CV5 and offer Midlands next-day £42–£70. For loads over a tonne of clay tiles, a hiab drop is usually more economical than multiple van runs.
Embodied carbon: Reclaimed Clay Roof Tiles in Coventry vs new
Choosing surplus or reclaimed clay tiles in Coventry avoids the A1–A3 manufacturing emissions of newly produced stock. On a typical Coventry project this equates to roughly 86–172 kgCO₂e per 1,000 — material evidence under Part Z, RICS WLCA and BREEAM Mat 06.
West 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 clay tiles purchase inside CV1, CV3 and CV5 builds an audit trail that stands up to WLCA review.
- A1–A3 avoided: ~86–172 kgCO₂e per 1,000
- A4 (transport): actual mileage from the Coventry 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 West 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: Coventry yards are quieter and forklift drivers have time, so you avoid the CV1, CV3 and CV5 weekday delivery crush.
- Ask for the yard's "just arrived" list — the best clay 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 Coventry
Reclaimed materials from private sellers are typically zero-rated for VAT. Surplus stock from VAT-registered West 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 clay tiles packaging for retrofit and Part L evidence
- Log the Coventry postcode of the source yard against the project record
Frequently asked questions
+Does surplus clay tiles count for PAS 2035?
Yes when spec and certification are preserved. Keep batch numbers and BBA certificates with your evidence pack.
+How many clay tiles per m²?
Plain: 60/m². Pantiles: 16/m². Peg: 55–65/m².
+Can I use surplus on ECO4-funded work?
Yes — ECO4 assessors care about spec and installation quality, not new-vs-surplus provenance.
+Is surplus clay tiles covered by manufacturer warranty in Coventry?
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 West Midlands orders.
+Can I count reclaimed clay 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 Coventry as evidence.
+What insurance sits behind a SurplusBuilder deal in West Midlands?
Verified sellers carry public liability and product-liability cover. Pallet-network deliveries insure to £1,300/pallet by default; declare higher values for premium clay tiles loads.
