Our Services

Most water compliance is fragmented: testing here, servicing there, remediation somewhere else. We've integrated every step, from diagnosis to solution, so you get consistent quality, audit-ready documentation and one accountable partner.

Legionella Risk Assessments

Legionella Risk Assessments

Our Legionella Risk Assessments provide a detailed evaluation of your water systems to identify potential risks, ensure legal compliance, and protect occupants. We assess system design, usage, and control measures to highlight areas of concern and provide clear, actionable recommendations.

Identifying risks. Protecting people. Ensuring compliance.

Water System Monitoring

Water System Monitoring

Regular monitoring is essential to maintaining safe water conditions and preventing bacterial growth. We record temperatures at every visit, and if anything is out of specification we explain what's wrong and why, then put it right on site.

Ongoing oversight for safer, compliant systems.

Water Sampling

Our water sampling confirms the quality and safety of your water through UKAS-accredited laboratory testing. We test for Legionella and microbial contamination, and if any results come back out of specification, we offer solutions and put them right on site.

Laboratory-verified water safety you can trust.

TMV Servicing

TMV Servicing

Thermostatic Mixing Valves play a critical role in preventing scalding and maintaining safe water temperatures. Our TMV servicing ensures valves are functioning correctly, cleaned regularly, and compliant with safety standards.

Safe water temperatures where it matters most.

Outlet De-Scaling

Mineral build-up and limescale can reduce water quality and increase hygiene risks. Our outlet de-scaling service professionally cleans taps, showers, and outlets to improve flow, hygiene, and overall system efficiency.

Cleaner outlets. Better hygiene. Improved performance.

Important Point for Outlet De-Scaling:

Remedial Plumbing

Remedial Plumbing

When a risk assessment or monitoring visit finds something that doesn't comply, we put it right. We carry out all L8 remedial plumbing works, from dead leg removal to tank replacement, and update your records so every fix is documented and audit-ready.

Something doesn't comply? We rectify it.
