WAC Testing & Waste Classification in London
Soil sampling, UKAS WAC analysis and WM3 hazard assessment for sites across London and Greater London. Classification tells you where your arisings can legally go before you commit to a disposal route — which on most London schemes is the difference between a straightforward muckaway and a stopped programme.
London site conditions we plan around
London demands a supplier that understands logistics as well as materials. Most central drops are timed to 30-minute windows with grab or HIAB access, and our hauliers operate FORS Silver, ULEZ and DVS-compliant vehicles for schemes that require compliant transport. Muckaway is the other half of the job here — constrained sites need muck off before stone can come on.
Lead times & access
Same-week dispatch on stocked lines to all 32 boroughs and the City, with most orders on site within 24–72 hours. Tipper, grab, HIAB and bulk-bag options for restricted-access sites in Zones 1–2, plus night and weekend windows where daytime access is not practical.

WAC testing in London — FAQs
Why does a London site need WAC testing?
A licensed facility can only accept material it's permitted to take. Testing classifies the arisings from your London dig so the right facility is booked first time, rather than a lorry being turned away and the programme slipping.
How long does WAC analysis take?
Standard turnaround is typically around five working days from sample receipt, with accelerated options from about 24 hours where the programme demands it.
Do you sample, or can I send my own samples?
Either. We can attend site and sample to BS EN 14899, or run the analysis on samples you've taken yourself if the sampling regime is sound.
Can testing and muckaway be booked together in London?
Yes — that's the usual approach. We test first, confirm the route, then mobilise haulage to the licensed facility so there's no gap between classification and removal.
