Do you need WAC testing in Sussex?
WAC testing confirms how excavated material must be legally disposed of, preventing rejected loads, spiralling landfill costs and delays at validation or discharge.
We help homeowners, developers and contractors confirm waste classification early, align disposal routes, and avoid expensive misdirection of soils or spoil.
Across Sussex, WAC testing is most often required where development interacts with:
Former brickworks and mineral extraction land around Storrington, Faygate and Upper Beeding, where historic landfill and clay extraction waste alter soil chemistry.
Shoreline and estuary redevelopment between Shoreham, Newhaven and Rye, where tidal silts and dredged material introduce contamination complexity.
Brighton & Hove brownfield infills and terraced demolitions, where historical backyard waste pits and coal storage leave unpredictable fill.
Rural estate conversions near Horsham, Midhurst and East Grinstead, where long-term agricultural chemical inputs influence leachability behaviour.
Transport and logistics expansion corridors on the A27/A23 network, where mixed rubble and demolition spoil produce variable WAC outcomes.
These landscape conditions frequently trigger WAC requests at planning, waste transfer and permitting stages.
Our WAC testing service supports projects across Sussex and nearby areas, providing landfill classification and disposal clarity for residential, commercial and redevelopment sites.

FAQ - WAC Testing in Sussex
What is WAC testing?
WAC testing stands for Waste Acceptance Criteria testing. It is a laboratory test used to determine whether waste material, such as excavated soil, can be disposed of at landfill. The testing assesses what contaminants could leach from the material and whether it meets the acceptance limits for different landfill types.
When is WAC testing required on a Sussex construction site?
WAC testing is usually required when excavated material is being removed from a site and sent to landfill. This commonly occurs during housing developments, infrastructure works, and brownfield redevelopment projects across Sussex. Landfill operators typically require WAC results before they will accept waste.
What does a WAC test analyse?
WAC testing measures the leaching potential of contaminants from waste material. Laboratories analyse substances such as heavy metals, sulphates, chlorides, and dissolved organic carbon. These results show whether the waste is suitable for inert, non hazardous, or hazardous landfill disposal.
What is the difference between waste classification and WAC testing?
Waste classification determines whether a material is hazardous or non hazardous under waste regulations. WAC testing then assesses whether that waste can be accepted at a particular landfill. In most projects, waste classification is completed first, followed by WAC testing if landfill disposal is required.
What types of waste materials need WAC testing?
Typical materials include excavated soils, made ground, remediation spoil, demolition fines, and dredged sediments. In Sussex, WAC testing is often required during redevelopment of brownfield land, construction projects, and infrastructure works where surplus material must be taken off site for disposal.
Why is WAC testing important before waste is removed from site?
Without WAC testing, landfill sites may refuse to accept waste. Testing confirms whether the material meets the acceptance criteria for the receiving facility. This helps prevent rejected loads, delays to construction works, and incorrect waste disposal.
How long does WAC testing take?
Most WAC laboratory tests take a few working days once samples have been received. The exact timeframe depends on the number of parameters being analysed and the laboratory turnaround requested. Early testing can help avoid delays once excavation works begin.
Can WAC testing help reduce waste disposal costs?
Yes. Accurate testing can show that waste is suitable for a particular landfill classification rather than assuming a higher risk category. This can help ensure the material is disposed of appropriately and avoid unnecessary disposal costs.
Who regulates waste disposal in Sussex?
Waste regulation in Sussex is overseen nationally by the Environment Agency, while planning matters relating to waste development are handled by the relevant local authority. Useful information can be found on the planning pages of West Sussex County Council and East Sussex County Council, which provide guidance on waste related planning matters.

Do all construction projects need WAC testing?
Not every project requires WAC testing. It is only needed when waste is being sent to landfill and the landfill operator requires confirmation that the material meets acceptance criteria. However, many construction and remediation projects still require testing before waste can be disposed of.
