What are remedial and improvement works?

Remedial and improvement works are actions taken to resolve issues identified during a risk assessment, inspection, or monitoring visit and to improve the safety and performance of your water systems. They turn recommendations into completed actions, closing out risks and strengthening compliance.

Our teams carry out the full range of remedial and improvement works, from removing dead-legs and replacing components to insulation, lagging and system alterations. We prioritise work by risk, coordinate delivery around your operations and document completion, so you can demonstrate that actions from your risk assessment have been closed within the agreed timescales.
