Accredited Legionella Control

We are members of the Legionella Control Association and accredited to the highest standard in everything we do, so you can trust Franks Portlock to provide you with the expertise you need to manage your risk in the most cost effective way. The engineers are also WRAS approved for RPZ valve testing and TMV servicing.

Once the risk assessment has been carried out, and the risks have been identified, they must be removed or at the very least, reduced to as low as reasonably practicable (ALARP). Each action raised within the risk assessment must be signed off to complete the risk assessment itself. This would be classed as carrying out Legionella remedial works.

The list below are examples of remedial actions that may be highlighted within a Legionella Risk Assessment that can be undertaken by Franks Portlock:

  • Blind end / Dead leg removal (redundant pipework) or other unwanted water services 
  • Cold water storage tank (CWST) clean and disinfection 
  • CWST relining (WRAS approved) 
  • CWST replacement – GRP, plastic, sectional steel & galvanised 
  • CWST upgrade to ensure compliance with current water regulations 
  • Installing, repairing or replacing water heaters and calorifiers 
  • Installation of flow through expansion vessels 
  • Installation of low volume water heaters (above and below sink) 
  • Installation or replacement of pipework, stopcocks, isolation valves, double check valves etc. 
  • Installation or replacement of shower pumps/water pumps 
  • Installing/replacing ball valves (including delayed Action) 
  • Insulation of vessels / CWST & pipework, including BS pipe identification labeling 
  • Main’s injection disinfection 
  • Reconfiguration of pipework within a cold-water storage tank (improved flow pattern) 
  • Reservoir fogging / disinfection 
  • RPZ valve installation and testing 
  • Thermostatic mixing valves servicing and installation

The work is normally discussed with your service provider, to obtain the best possible solution to rectify the issue. This is where Franks Portlock can use its years of experience in assisting the client with the best, most cost-effective solution.

Why do I need Legionella remedial work?

Anything identified during a Legionella Risk Assessment, annual audit or a routine inspection, that does not meet the required standards or guidelines, will be highlighted within an exception report. These exceptions will need to be addressed within a specified time frame. The urgency of each item will be ranked within the reports, to assist in the prioritisation of the works.

How long will the legionella remedial works take?

From the outset our engineers will ensure that the legionella remedial works are carried out with minimal disruption to your business. Factors such as easy access to rooms and buildings will contribute to time spent on site, along with the amount of work that is required. If you’re after an estimated time frame contact our team to discuss!

What do I do after the Legionella remedial works?

Remedial works are usually identified as part of the recommendations within a Legionella Risk Assessment and must be completed to close the risk assessment off. Each remedial action will be undertaken to reduce the risk of Legionella proliferation to as low as reasonably practical (ALARP). Once the remedial actions have been completed the system must be regularly monitored to ensure the remedial measures put in place remain effective. Guidance for the monitoring can be found in the HSE guidance document HSG274 parts 1,2 & 3.

    Bernard Interiors

    During a recent review by our Health and Safety consultant, it was noted that a Legionella Risk Assessment was necessary for our studio. We contacted Franks Portlock who undertook a full review of the premises and provided us with a greater understanding of the UK regulations and requirements. Sean Green supplied us with a detailed Legionella risk assessment and offered pragmatic advice and guidance on the procedures required to remain compliant, the whole process was seamless from start to finish.. Sean attention to detail and dedication was faultless throughout the entire process and it was a pleasure to work with both him and the team.

    The de Ferrers Trust

    Six months ago, we instructed Sean and the team at Franks Portlock for their services in Water Hygiene and we have been blown away by the service he has provided us. We have a number of different schools on board with him that range from full water hygiene monthly management, to RA's and Annual services. When tendering we found that Frank's Portlocks cost were similar to what we were already paying, however the level of detail that the contract covers far outweighs any previous contract we've ever had. The Monthly meetings have made a massive difference in ensuring that faults and risk items are dealt with promptly and appropriately. As the person who oversees compliance across our trust, I no longer have to worry about the water hygiene compliance in our schools that use Franks Portlock.
