Be sure. Be safe. Be sustainable.

Testex is a service that aims to offer a complete waste

management solution to your assessment obligations and technical guidance requirements.

We offer rapid environmental testing, which is supported by our team of qualified specialists.

We are able to meet all your duty of care requirements in the most efficient and effective way.



For over 25 years, our environmental waste testing facility has developed a key understanding within this sector. We will ensure all environmental waste classification requirements are compliant and correctly met.

Testex provides detailed site reports. These will include a comprehensive summary and breakdown of your site, accompanied by appropriate WM3 waste certification.

We include a site waste management plan, all conveniently handled via just a single point of contact.


Our friendly in-house team offers a full waste consultancy service and can provide you with helpful expert advice to optimise waste management budgets, and programmes to minimise site costs and delays.

By correctly identifying waste streams in the minimum time-frame possible, our operational and logistics teams – supported by London’s largest tipper and grab fleet – can remove, handle, and recover all materials, minimising landfill in the process.

As leading proponents of the circular economy, much of the non-hazardous waste we recover is recycled and reused to produce quality materials, to meet society’s need to deliver more sustainable outcomes within the construction, demolition, and utility industries.

We comply with all necessary environmental regulations, as all of our work is tested under the guidance of WM3 regulations and is EA recognised.




Environmental law assumes the waste producer to be ultimately responsible for the classification, collection and disposal of its own waste. We understand that many sites do not have the necessary site investigation analysis, often out of date and/or out of context, sometimes none at all.

All parties including hauliers and waste disposal facilities carry this responsibility. Testex aims to provide clear direction for our clients. Misclassification of waste is a serious offence, carrying criminal and large financial penalties.

Waste Testing

Site investigation

Our detailed site investigation methodology includes a thorough inspection of waste samples, coupled with detailed site history and research to ascertain the background and nature of the land.

In most cases, brownfield sites will have undergone a variety of uses in the past.

Ensuring the right waste classification is vital. Should the site contain any hazardous waste, it is critical to identify this at the earliest possible stage, minimising the risks to all people coming into contact with it.

Site appraisal

Full site appraisal is included within the report, detailing photographs, site description, history, future use, and physical composition, with relevant mapping and sampling test types by location.

Waste testing and results

Test results detail all specified recordable substances and compounds to categorise if the waste is hazardous or non-hazardous, stating the recommended removal and treatment management plan.

Site report

Testex provides a complete site report and compliant waste assessment of all detected substances by name and their quantities in the HazWasteOnline report record, including the hazardous/non-hazardous confirmation certificate, to meet your obligations as a waste producer.


Waste Removal, Disposal and Treatment

Recommendations and guidance on how to best handle your waste in the most environmentally sensitive manner will be given. We will provide an operational plan to maximise best practice on how to remove and handle your waste in the most effective way.

Digital documentation

We’ve developed our own digital comms and documentation interface to meet current and future planned legislation, ensuring full waste traceability by load and specific classification.

All of which can be handled by London’s largest fleet of tipper and grab vehicles servicing your requirements.

Sivyer currently manage in excess of one million tonnes of waste per year servicing the capital.
