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.

Options for London sites
Sample screen
Basic classification screen to confirm whether material is inert, non-hazardous or hazardous.
Full WAC suite
Complete leachate analysis for landfill acceptance where the facility requires it.
On-site sampling visit
Our sampler attends, takes representative samples across the stockpile or dig and logs the locations.
Fast-track turnaround
Accelerated lab options from around 24 hours where the programme can't wait.
How it works
01
Sampling
Representative samples taken to BS EN 14899 across the material to be moved.
02
Laboratory analysis
UKAS lab runs the agreed suite, from screen through to full WAC leachate testing.
03
Classification and route
WM3 assessment issued, then we confirm the licensed facility that can accept the material.
Compliance and paperwork
Sampling follows BS EN 14899, leachate testing follows BS EN 12457-3 and analysis is carried out by UKAS-accredited laboratories, with WM3 assessment reports for your site file.
Our credentialsWhat shapes WAC testing in London
Classification matters in London because of clay and made ground that usually needs classifying before a disposal route can be booked. With London clay and deep made ground under most central plots, arisings from neighbouring plots can behave very differently, so sampling across the dig rather than one spot sample is what keeps the result usable. On basement digs, borough highway packages and public-realm schemes we test first, confirm the facility, then mobilise haulage — the same sequence across Croydon, Watford and Romford.

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.
Do you deliver inside the Congestion Charge zone?
Yes — we run ULEZ and DVS-compliant vehicles and coordinate Zone 1 drops around the 07:00–22:00 charging window, or schedule night deliveries for low-disruption sites.
