Legionella bacteria thrive in water systems where temperatures and conditions allow them to multiply. If left unchecked, they can cause serious illness, including Legionnaires' disease, a potentially fatal form of pneumonia.

Landlords, facilities managers, and business owners all have a legal duty to assess and control the risk of Legionella in their water systems. This includes hot and cold-water systems, cooling towers, and any equipment that generates water droplets or spray. Legionella risk assessments are essential for meeting these obligations.

At SESC Solutions, we carry out thorough Legionella inspections across commercial and residential properties in Dorset and the surrounding counties. Our qualified engineers assess your water systems, identify potential risks, and provide clear recommendations to keep your building safe and compliant.

When it comes to a Legionella risk assessment, UK regulations must be followed to protect occupants and meet your legal obligations. With our help, you can be confident of staying compliant.

Legionella Risk Assessment FAQs

A Legionella risk assessment is a structured inspection and evaluation of your water systems to identify potential hazards and assess the likelihood of bacterial growth. The process involves hazard identification and evaluation, checking storage tanks, pipework, outlets, and any equipment that uses or stores water.

Our engineers carry out a detailed water system inspection, documenting temperatures, flow rates, and dead legs. Each risk is scored based on severity and likelihood, and we provide a clear action plan to reduce or eliminate those risks. The final report outlines what needs to be done and when, giving you a roadmap to compliance.

UK law requires duty holders to assess and manage the risk of Legionella in their water systems. The Health and Safety Executive (HSE) sets out clear expectations for landlords, employers, and those responsible for buildings.

Duty holder responsibilities include identifying hazards, implementing controls, and keeping records. A water safety risk assessment protects employees, tenants, and visitors from exposure to harmful bacteria. It also demonstrates compliance with health and safety regulations, helping you avoid enforcement action, fines, or prosecution.

Beyond the legal requirements, it gives you confidence that your building is safe and well maintained.

Legionella risk assessments should be reviewed every two years at a minimum, or sooner if your water system changes. Building alterations, new equipment, or occupancy changes can affect your risk profile. As the duty holder, it's your responsibility to keep assessments current and accurate. If you're unsure whether yours needs updating, our team can advise.

You should keep a copy of your risk assessment report, records of any remedial work carried out, temperature monitoring logs, and details of routine maintenance and inspections. These records demonstrate your ongoing compliance and provide an audit trail if you're ever asked to show how you manage water safety. Store them in a central location and make sure they're accessible to relevant staff or contractors.

Yes, we offer ongoing Legionella assessment services to help you stay compliant over time. This includes routine temperature checks, system monitoring, and periodic reviews of your Legionella risk assessments. Our team can set up a schedule that suits your property and ensures your water systems remain safe. If you need support managing your responsibilities, we're happy to discuss a tailored maintenance plan.

Dorian and his team and office staff have been excellent. While others who quoted for the work fail to show up or didn’t understand the requirement, or simply incorrectly specified solutions, SESC came up with a bespoke design that exceeded my expectations at a fair price. Always a pleasure to deal with. They have a great range of skills. I would highly recommend them. Great heat pump install, cylinder, UFH install and refit of existing solar thermal, and all in a super tight space.

Thank you Dorian and the team for a great Vaillant heat pump and new central heating installation. The installation took about 2.5 weeks to have everything wrapped up, as there was a slight delay in the stock of the specific radiators we wanted, but the team worked very hard indeed to successfully take on some of the challenges of the install. They were extremely tidy (the house has never been so clean!) and conscientious with their work. Dorian is a real stickler for the small details, guiding us through the install and checking exactly how we wanted everything. Since then, the system has been running really well. Very efficient, pushing over 400% for heating and hot water since the installation in September 2025, and performing very well during cold snaps. House stays a nice consistent temperature without costing a lot on our electricity bill. Having previously had electric and night storage heaters, the new system is a massive improvement. Where there have been a couple of snags, Dorian has been more than happy to check, fix, and advise in a very prompt manner. Overall, definitely recommend when considering a heat pump installation.

I am happy to recommend SESC solutions to anyone considering a solar energy system. I have been very impressed by the fantastic customer service and advice that SESC provided throughout our large domestic solar panel and battery storage installation project. The team were available day and evening to answer my many questions, and updated the quotation several times to fit our specific requirements. The SESC quotation included everything right from the start, such as scaffolding and bird guards, that were usually left out of other companies quotes, and a pre-installation assessment checked everything was in order. The installation day was even sooner than expected and the roofer and electricians were very professional and helpful, with everything arriving on site smoothly and all rubbish taken away. Following the installation, we have quickly received all the documentation to help us switch supplier and take up the SEG for exporting our excess electricity. I have every confidence that the SESC team will continue to be there on the end of the phone if I need any further advice or support in the future.

I could not recommend Steve and his team at SESC Solutions more highly and wouldn't hesitate to work with them again for future projects. SESC Solutions have helped us for both London and country projects. The work has always been completed to a high standard and the work has always been well managed with clear communication throughout. We look forward to working with SESC again soon.
