How do I know I need remedial works?

Remedial Works are normally identified and detailed in the Recommendations section of the Legionella risk assessment report and the water system monitoring and temperature testing reports. Your specialist contractor should be providing these reports to you on a regular basis, detailing the level of risk that the issue poses and the actions you should take.

Remedial works can involve:

  • Removing rust, limescale, sediment and other biofilms from Cold Water Storage Tanks, Calorifiers and Water Heaters, and the system pipework and other assets
  • Upgrading the design of the hot and cold water system to minimize the risk from Legionella
  • Removal of redundant pipework causing dead ends and creating stagnant water opportunities
  • Cleaning and servicing of assets such as water storage tanks, Calorifiers, Showers and Thermostatic mixer valves (TMV’s)

We have specialist engineers who are able to inspect, upgrade, remove and install various hot and cold-water systems including pipe work. We work to current regulations and standards such as ACoP L8, HSG 274 parts 1,2 and 3, BS8558 and COSHH regulations.
