Site over-orders, cancelled jobs and careful strip-outs are where the best material bargains in the UK come from — this lot is one of them. This is unused, current-spec material — the only thing second-hand about it is the price tag logic.
Reusing this material saves roughly 147 kg CO₂e versus manufacturing a new fired clay brick (~0.5 kg CO₂e per brick, BRE Global data).
That's equivalent to about 867 km of average petrol-car driving, or what 7 mature trees absorb in a year.
Reuse is the single fastest way to cut a build's embodied carbon — substitution beats offsetting every time.
The headline saving on this listing (~147 kg CO₂e) is benchmarked against manufacturing a new fired clay brick (~0.5 kg CO₂e per brick, BRE Global data). That's the embodied-carbon figure — the emissions locked into new material at the point of manufacture, before it ever reaches your site.
In UK building terms, embodied carbon typically accounts for 40–60% of a project's whole-life emissions once operational energy is decarbonised. Reusing masonry like this lot from Glasgow bypasses the manufacturing stage entirely, which is why substitution consistently outperforms offsetting on lifecycle assessments.
For projects tracking against Part Z (the proposed embodied-carbon amendment to the Building Regulations), BREEAM Mat 01 credits, or the RIBA 2030 Climate Challenge, reused material counts at zero embodied carbon in the A1–A3 modules. Keep the seller invoice, this listing URL and the CO₂e figure together in your carbon file.
Beyond carbon: buying this lot from Glasgow Greenfield Contractors keeps first-quality masonry out of the UK construction waste stream (currently ~62 million tonnes/year, per DEFRA). It supports the circular-economy supply chain — sellers who divert stock only continue diverting when there's a viable resale route.
Standard UK bricks lay at ~60/m² in a single skin with 10mm joints. This lot (2.0 tonnes) is best confirmed against your wall area plus a 5% cutting allowance.
Bricks that have survived decades outdoors in Glasgow have effectively passed the longest freeze-thaw test there is. We still recommend F2-rated units for exposed copings and below-DPC work.
Yes — the seller (Glasgow Greenfield Contractors) will set aside sample units for inspection at the Glasgow yard before you commit to the full quantity.
Glasgow Greenfield Contractors issues a VAT invoice on collection or dispatch — bank transfer is standard, card on request. For anything over £500 we recommend a written spec confirmation before paying, so the exact masonry description and quantity are on record.
A short reservation (typically 48–72 hours) is usually possible with a 10% holding deposit. Surplus stock moves quickly, especially new surplus lots at this price point — confirm the hold in writing so the seller doesn't re-list.
Yes — the ~147 kg CO₂e saving is calculable against the benchmark in the sustainability notes above; keep this listing URL as evidence for your embodied-carbon log.
