Reclaimed Sash Windows Buyer's Checklist London 2026
Every London buyer needs a consistent inspection process for sash windows. This 2026 checklist covers what to check, questions to ask the seller, and how to protect a payment.
Before you go
- Ring ahead — confirm the sash windows is still on the yard
- Ask for photos of the exact stock
- Confirm price per unit and total
- Route-plan to the London yard, factor in weight for return trip
On the yard
- Victorian and Edwardian 6-over-6 and 2-over-2 lights
- Original crown glass and horns intact where possible
- Solid pine boxes — reproduce or refurbish
Payment protection
- Prefer card over cash for larger buys
- Get an invoice with VAT number where applicable
- Photograph loaded vehicle before leaving
- Keep receipts against manufacturer warranty (surplus)
Collection and delivery inside London
Most London sellers hold stock inside N, E, SE and SW postcodes and offer same-day van hire from £120; hiab drops £180–£280. For loads over a tonne of sash windows, a hiab drop is usually more economical than multiple van runs.
Embodied carbon: Reclaimed Sash Windows in London vs new
Choosing surplus or reclaimed sash windows in London avoids the A1–A3 manufacturing emissions of newly produced stock. On a typical London project this equates to roughly 26–52 kgCO₂e per window — material evidence under Part Z, RICS WLCA and BREEAM Mat 06.
Greater London 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 N, E, SE and SW postcodes builds an audit trail that stands up to WLCA review.
- A1–A3 avoided: ~26–52 kgCO₂e per window
- A4 (transport): actual mileage from the London 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 Greater London 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: London yards are quieter and forklift drivers have time, so you avoid the N, E, SE and SW postcodes 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 London
Reclaimed materials from private sellers are typically zero-rated for VAT. Surplus stock from VAT-registered Greater London 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 London postcode of the source yard against the project record
