Muck Away Prices South Wales 2026
Muck away costs vary significantly depending on soil type, volume, and any contamination present. Here are typical 2026 prices for South Wales:
| Waste Type | Price Per Load (approx) | Lorry Size |
|---|---|---|
| Clean topsoil | £250–£320 | 8-wheel, 16t |
| Clay / subsoil | £270–£350 | 8-wheel, 16t |
| Mixed excavation waste | £300–£400 | 8-wheel, 16t |
| Hardcore / concrete mix | £310–£420 | 8-wheel, 16t |
| Contaminated soil | £380–£550+ | With hazardous docs |
| Small loads (6-wheel) | £230–£300 | 6-wheel, 12t |
How Many Loads Will My Project Need?
Calculating your load count before work begins prevents budget surprises. The key formula:
Load Count Formula:
(Length m × Width m × Depth m) × 1.3 (bulking) × Density (t/m³) ÷ Lorry capacity (t)
Example — house extension foundation (6m × 5m × 1.2m deep, clay soil):
Volume = 6 × 5 × 1.2 = 36m³
Bulked volume = 36 × 1.3 = 46.8m³
Clay density = 1.8 t/m³ → 84.2 tonnes
8-wheel loads = 84.2 ÷ 16 = 6 loads (round up)
South Wales Soil Types — What You'll Find
South Wales has diverse geology that affects muck away costs:
Cardiff Bay / Coastal
Soft alluvial clay, made ground from dockland reclamation. Potentially contaminated. Lighter but bulks significantly.
South Wales Valleys
Heavy clay, shale, and coal measures. Dense material — high tonnage per cubic metre. Mining disturbance common.
Newport Industrial
Made ground over industrial land. High contamination risk from steelworks and chemical industries. Requires site investigation.
Monmouthshire / Rural
Natural clay and limestone over agricultural land. Generally cleaner, consistent material. Lower contamination risk.
Vale of Glamorgan
Mixed agricultural soils over limestone. Relatively clean, consistent. Good for clean soil diversion to reuse.
Swansea / Neath
Industrial legacy from copper smelting and coal. Brownfield sites frequently contaminated. Phase 1 desktop study recommended.
Legal Requirements for Muck Away in South Wales
Muck away is not just a logistics operation — it's a legally regulated waste management activity:
- Waste Transfer Note (WTN): Required for every load under the Environmental Protection Act 1990. Must identify waste producer, carrier, waste type, and disposal facility. Retain for 2 years.
- Licensed carrier: Your contractor must hold a current Environment Agency waste carrier licence. Always ask to see it — using an unlicensed carrier makes you liable as waste producer.
- Contaminated waste: Requires an Environmental Consignment Note (ECN) with pre-notification to the Environment Agency. Disposal must be at a licensed hazardous waste facility.
- Duty of Care: As the waste producer, you have a legal Duty of Care under the Environmental Protection Act to ensure your waste is correctly described, handed to a licensed carrier, and disposed of legally.
We handle all documentation
Every muck away load we collect from South Wales sites comes with a Waste Transfer Note and full disposal documentation. You don't need to worry about compliance — we manage it all.

What is the difference between muck away and grab hire?
Muck away specifically refers to excavation waste removal — soil, clay, and subsoil. Grab hire is a broader term covering any waste collected with a hydraulic grab arm, including rubble, hardcore, green waste, and mixed construction waste. In practice many companies use both terms interchangeably.
How do I estimate how many loads of muck away I need?
Calculate the excavation volume in cubic metres (length × width × depth), then multiply by 1.3 (30% bulking factor) and by your soil density (typically 1.5–1.8 t/m³ for clay). Divide by lorry capacity (12t or 16t) for load count. Use our muck away calculator at jamesgrabhire.co.uk/muckawaysouthwales.
Can you remove contaminated soil in South Wales?
Yes — we hold full Environment Agency hazardous waste carrier licensing for contaminated soils from brownfield and industrial sites across South Wales. All hazardous movements are documented with consignment notes.
