Revised flow temperatures for heating systems increase risk of Legionella

   09 January 2024         News

In a significant update to Part L of the Building Regulations (Conservation & Power),  professionals who install, commission, maintain, monitor, and manage heating systems, are set to face a major shift in regulations concerning flow temperatures. The new guidelines emphasise that, for heating systems, flow temperatures should not exceed 55°C, and ideally, they should be kept below this threshold.

The guidelines state that,

“All parts of the system, including pipework and emitters, should be sized to allow the space heating system to operate effectively, and in a manner that meets the heating needs of the building, at a maximum flow temperature of 55°C or lower. To maximise the efficiency of these systems, it would be preferable to design to a lower flow temperature than 55°C. Where it is not feasible to install a space heating system that can operate at this temperature (e.g. where there is insufficient space for larger radiators, or the existing distribution system is provided with higher temperature heat from a low carbon district heat network), the space heating system should be designed to the lowest design temperature possible that will still meet the heating needs of the building.”

The reduced temperatures are primarily in response to new condensing boilers. The water returning to the boiler needs to be lower than 55 °C otherwise the water won’t condense and therefore it would be like having a non-condensing boiler, which defeats the point.

While this change brings about several advantages in terms of energy efficiency and environmental impact, it also introduces a new consideration for those that manage secondary hot water systems heated by them — the increased risk of Legionella bacteria formation in hot water systems due to decreased hot water flow, return and distribution temperatures. It will also have impact on the scald risk and management protocols, amongst others.

Legionella is a waterborne pathogen that can lead to acute respiratory pneumonia. The bacteria multiples between the temperatures of 20°C and 45° which is more likely as a consequence of this change.

Hot water systems face increased risk of Legionella bacteria

Dan Sutherland, Senior Water Systems & Legionella Trainer at Develop Training explains,

It is important that industry understands, communicates and provides specific risk assess guidance on each situation on its own merits. This can be challenging and so developing employee competence is part of this (partly achieved through training). Late understanding of these principles impacts businesses and individuals from a commercial, financial and personal aspect.”

He continues,

Where the hot water system represents a lower risk from legionella, reduced hot water temperature may have little impact (typically in domestic dwellings and smaller commercial settings) but in larger commercial and healthcare systems (and commonly older systems), maintaining traditional hot water flow and return temperatures of 60°C and 50°C may still be a key control.

There is also impact in the world of scald prevention and thermostatic mixing valves – can these valves now be removed in some settings? Will they continue to work effectively due to reduced supply temperatures? What is the possible impact and effect on build quality requirements, and will hot water system design change as a consequence?

We should also remember that best practice up to now has been to supply hot water to kitchens for hygiene reasons of at least 55°C.”

Legionella training a critical factor in mitigating risk

To address this concern, training providers in the Building Services industry play a crucial role in ensuring that professionals are well-informed and equipped to navigate these evolving regulations. It is essential for heating engineers and those who work with hot water systems to stay up to date with the latest industry standards, enhance their knowledge of Legionella prevention measures, and implement best practices in their installations to uphold both safety and efficiency.

As the industry adapts to these changes, Develop Training will be incorporating the latest updates into its curriculum, ensuring that heating engineers are well-prepared to meet the demands of the evolving regulatory landscape. This proactive approach will not only enhance the skills of professionals in the field but also contribute to creating safer and more energy-efficient heating systems for the benefit of both consumers and the environment.

Develop Training creates bespoke incident management training programme for firmus energy

   05 January 2024        News

In a strategic move to improve incident management and enhance the preparedness of its staff, firmus energy, a natural gas supplier in Northern Ireland, has collaborated with Develop Training, a renowned utilities training provider.

The objective was clear: to rigorously test procedures and ensure that firmus’ engineering and technical teams were well-equipped to handle real-world incidents. The decision to opt for Develop Training was influenced by the organisations’ successful track record in creating bespoke incident management training programmes for utility companies.

Training expertise in incident management for the gas industry

The driving force behind firmus’ choice was the wealth of experience brought to the table by Develop’s experts, Jim Donnelly and Chris Parker, both of whom have many years experience of working hands on in the gas industry and devised a similar training initiative for Phoenix Energy last year.

The bespoke programme of training designed by Develop brought together various teams within Firmus, fostering collaboration among individuals who may not typically work together on a day-to-day basis but would have to work effectively together in the case of a serious incident. The training aimed to simulate real-life incident scenarios, allowing the group to test procedures and for Jim and Chris to gather invaluable feedback from those involved. The pair also assessed how the group responded both as a team and individuals. The feedback was then presented to firmus and an action plan created.

Positive feedback from delegates and employer

The feedback from the participants was overwhelmingly positive. Many expressed that the experience was not only enjoyable but also deeply appreciated.

One delegate said,

The training was a fantastic opportunity for us to demonstrate our ability to react to a simulated incident, uncovering potential areas for improvement in procedures. The best way to learn is by actively doing the task so I found it incredibly useful to do this training and it’s definitely given me some learning points to go away and put into practice.”

One of the standout benefits cited by firmus was the opportunity to receive direct feedback from the individuals who participated in the training. This feedback loop proved instrumental in shaping the action plan.

Chantal Hemphill, HSE Manager at firmus, expressed her satisfaction with the collaboration, stating,

Working with Develop Training has been an incredibly valuable experience for firmus. Jim and Chris were clearly very experienced, making us feel comfortable throughout the process. Their professionalism and commitment to ensuring our teams were well-prepared for any incident were evident, and we are grateful for the positive impact this training has had on our organisation. There have been some clear takeaways that the training highlighted and we’re now working through the action plan to address these.”

A bespoke training package for incident management and response in the gas industry

As effective incident management and response continues to play a key role in the utilities industry, investment in employee training proves to be essential for companies like firmus. Develop Training’s successful collaboration with firmus underscores the importance of hands-on, bespoke training in ensuring the preparedness and efficiency of industry professionals in handling real-world scenarios.

Incidents involving unsafe gas works make the headlines

   16 August 2023         News

Incidents involving poor or unsafe gas work continue to be a recurring problem across the UK, and one that should be a concern for all personal and commercial property owners.

The latest incident involves a self-employed plumber who carried out unsafe gas work in Hampshire and pretended to be Gas Safe registered.

Ben Craig Siddle, trading as BCS Gas and Plumbing, worked on numerous homes in Hampshire in 2021 and 2022 even though he was not a Gas Safe registered engineer.

Mr Siddle, 24, falsely represented himself as a Gas Safe registered engineer to customers and did not carry out the work to appropriate standards, leaving residents at risk from unsafe gas appliances.

He left two of the properties he worked on in an unsafe condition.

Gas Safe registered engineers were later required to correct and repair installations Mr Siddle had carried out at these properties. At one property on East Cosham Road, Portsmouth, the boiler and flue Mr Siddle installed were deemed immediately dangerous. A boiler Mr Siddle installed at another property on Howard Road, Portsmouth, was classed as at risk. (Source:

Gas Safe training is paramount

Poor workmanship could result in a life-threatening situation where appliances have actually been made dangerous by the illegal fitter, causing risk of explosion and/or of carbon monoxide (CO) poisoning.

This alarming news serves as a stark reminder to businesses and home-owners that it is vital to ensure you are checking the gas safe register before hiring a contractor.

Develop Training’s ACS gas training courses are NICEIC accredited, allowing the individual and/or employer to apply for Gas Safe Registration following successful completion of the training.

It is vital that anyone involved in gas works has up to date knowledge of the latest legislation and working practices, and is Gas Safe Registered.
