How we rank

Best Specialist Cleaning Companies is an independent comparison site for specialist, biohazard and trauma cleaning providers in the UK. Our goal is to help people find a compliant, capable provider quickly — often at a difficult time.

Our ranking criteria

• • Compliance — Environment Agency waste-carrier registration, HSE-aligned and COSHH-based procedures.
• • Response — availability and speed of response for urgent, high-risk incidents.
• • Breadth — range of specialist services (biohazard, trauma, after-death, sewage, decontamination).
• • Discretion — sensitivity and professionalism in distressing situations.
• • Documentation — infection-control processes and hazardous-waste consignment paperwork.

We include a range of providers so you can compare fairly. Rankings reflect the criteria above and our editorial assessment.
