What are Legionella remedial works?
Remedial works are the corrective actions that fix the problems found in a Legionella risk assessment, audit or inspection. They can be small, such as removing a dead leg, or larger, such as replacing a tank or altering pipework. We work to HSG274, supporting ACoP L8, BS EN 806 and the Water Supply (Water Fittings) Regulations 1999.
Unlike routine flushing and monitoring, remedial works deal with the root cause, so the same failure does not keep coming back. For the full detail, see our Legionella Remedial Works page.
- Dead leg and redundant pipework removal
- Pipework alterations to improve flow and layout
- Cold water tank repairs, new lids, insect screens and insulation
- Thermostatic mixing valves: installation, replacement and servicing
- Valves, stopcocks and double check valves
- Cleaning, disinfection and sampling after the works, where required

How remedial works are carried out
- We read your risk assessment and agree which actions are in scope, in priority order.
- We survey the work and send you a written quote.
- We agree timings with you so the work fits around your building and keeps disruption low.
- The work is carried out, with any isolation planned in advance.
- Where needed, we clean, disinfect and sample afterwards to confirm the system is ready for use.
- You receive a record of what was done and what could not be done, so you can close out the action in your risk assessment.
