Frequently Asked Questions

What is the F-Gas regulation?

The F-Gas Regulation N° 517/2014 is an EU legislative instrument which is directly applicable in all EU Member States. It was published in the Official Journal on 20 May, 2014 and replaces the 2006 F-Gas Regulation. The 2014 Regulation further strengthens the 2006 rules and contains some significant new provisions to reduce emissions.

How does the F-Gas regulation affect me?

HFCs are the most common type of F-Gas and are mainly used as the refrigerant in Air Conditioning and Commercial Refrigeration Systems. Therefore, all users of refrigeration and air conditioning equipment have responsibilities for the F-Gas they have in their mechanical heat pump, cooling systems and chillers. For the majority of uses, these must be checked and serviced at least annually. For more heavy duty equipment, this may mean bi-annual checks or the installation of fixed leak detection systems. Determining exactly how this applies to individual systems can be a little complicated, so we are here to provide specialist advice to assist you in meeting your legal responsibilities.

What is planned and unplanned maintenance?


Planned maintenance is works scheduled in, for instance carrying out routine job instructions via the Helpdesk or servicing boilers, pumps, fans, lights, air conditioning and electrical equipment. Unplanned maintenance work is reactive maintenance utilised when maintenance equipment (and/or fixtures and fittings) break down. It can also be a flood, gas leak or an emergency.

How many Engineers do you have?

We have over 40 excellent, experienced Engineers providing full coverage within London and the surrounding counties.

What is Legionnaires disease?

Legionellosis is a collective term for diseases caused by legionella bacteria including the most serious Legionnaires’ disease, as well as the similar but less serious conditions of Pontiac fever and Lochgoilhead fever. Legionnaires’ disease is a potentially fatal form of pneumonia and everyone is susceptible to infection.

Where does legionnaires disease come from?

Legionella bacteria are widespread in natural water systems (rivers and ponds). However, the conditions are rarely 'right' for people to catch the disease from these sources. Outbreaks of the illness occur from exposure to legionella growing in purpose-built systems, where water is maintained at a temperature high enough to encourage growth: cooling towers, evaporative condensers, hot and cold water systems and spa pools used in all sorts of premises (work and domestic).

As a Landlord what are my duties regarding legionella?

The legal duty for landlords (who provide residential accommodation) to consider, assess and control the risks of exposure to Legionella to their tenants is not new. This requirement stems from the Control of Substances Hazardous to Health Regulations 1989. Section 3(2) of the Health and Safety at Work Act 1974 makes provision for the legislation to apply to landlords of both business and domestic premises. All water systems require an assessment of the risk, which they can carry out themselves if they are competent or employ somebody who is.

Who can be appointed as the ‘responsible’ person to look after my water system?

The responsible person will take day-to-day responsibility for managing the control of any identified risk from legionella bacteria. Anyone can be appointed as the responsible person as long as they have the sufficient authority, competence, skills and knowledge about the installation. This ensures that all operational procedures are carried out in a timely and effective manner and that control measures and strategies are implemented the control (they are suitably informed, instructed, trained and assessed). They should be able to ensure that tasks are carried out in a safe and technically competent manner. If a dutyholder is self-employed or a member of a partnership, and is competent, they may appoint themselves. The responsible person should be suitably informed, instructed and trained, and their suitability assessed. They should also have a clear understanding of their duties and the overall Health and Safety Management structure, and policy in the organisation.

How do I control the risks from legionella in my water system?

The key point is to design, maintain and operate your water services under conditions that will either prevent or adequately control the risk from legionella bacteria. It is important that you either have, or have access to, competent help to fulfil these obligations. If you identify a risk that you are unable to prevent, you must introduce appropriate controls. You should introduce a course of action that will help you to control any risks from legionella by describing: • your system and its component parts (developing a schematic diagram); • who is responsible for carrying out the assessment and managing its implementation; • the safe and correct operation of your system; • what control methods and other precautions you will be using; • what checks will be carried out to ensure risks are being managed and how often.

Who can be appointed to test or monitor legionella?

Testing of your water quality may be carried out by a service provider, such as us, another consultant or your staff (provided your staff are trained to do so and are properly supervised). The type of test required will depend on the nature of the water of the system. HSG274 Legionnaires' Disease Technical Guidance provides further details for both evaporative cooling systems and hot & cold water systems.

How do I test or monitor legionella from my water system?

Where monitoring for legionella is considered appropriate, the sampling method should be carried out in accordance with BS7592 and the biocide, if used, should be neutralised where possible. Water samples should be tested by a UKAS-accredited laboratory that takes part in a water microbiology proficiency testing scheme such as that run by Public Health England. The laboratory should also apply a minimum theoretical mathematical detection limit of <= 100 legionella bacteria, per litre of sample for culture-based methods.

How often should I test water for Legionella?

It depends on the system that you have and the outcome of your risk assessment. For open systems (such as cooling towers, evaporative condensers and spa pools) routine testing should be carried out at least quarterly. However, there may be circumstances were more frequent sampling may be required. For hot and cold water systems, which are generally enclosed (not open to the elements and significant contamination in the same way as cooling towers) microbiological monitoring is not usually required. However, there may be circumstances where testing for legionella is necessary, for instance, where there is doubt about the efficacy of the control regime or where recommended temperatures or disinfection concentrations are not being consistently achieved. Further guidance is available in HSG274 Part 2.
