SFG20 is recognised as the definitive standard for maintaining, managing, and specifying the maintenance of building services. Developed by the Building Engineering Services Association (BESA), it provides comprehensive schedules and guidance to ensure systems are maintained safely, efficiently, and in compliance with industry best practice.
At Marlowe Environmental Services, we help organisations apply the principles of SFG20 across key areas of operation, including water hygiene and air quality management. Our experts support facilities managers, building owners, and maintenance teams in meeting their obligations under SFG20 and wider health and safety legislation.
SFG20 provides detailed maintenance instructions for all major building systems – including heating, cooling, ventilation, water, and electrical services. It sets out planned maintenance schedules, frequencies, and procedures that support both operational efficiency and regulatory compliance.
For organisations like those served by Marlowe Environmental Services, SFG20 plays a crucial role in preventing risks associated with Legionella bacteria and poor air quality. Adhering to SFG20 helps duty holders ensure that their maintenance regimes are aligned with the latest standards and legislation, such as the Health and Safety at Work Act 1974 and COSHH Regulations.
Key points of SFG20 include:
We work with building owners, facilities managers, and maintenance providers to ensure compliance with SFG20 and associated health and safety legislation.
Our support includes:
By partnering with Marlowe Environmental Services, organisations can ensure that their maintenance activities meet industry standards, support safety, and protect system efficiency.
Failure to maintain building services in line with SFG20 can lead to system breakdowns, poor air quality, and increased safety risks such as Legionella outbreaks or carbon monoxide exposure.
Applying SFG20 ensures:
Compliance with SFG20 demonstrates a proactive approach to safety, reliability, and sustainability, helping organisations maintain operational excellence and protect occupants.
SFG20 is the industry standard maintenance specification for building services, providing guidance and maintenance schedules for mechanical, electrical, and public health systems.
SFG20 applies to anyone responsible for building maintenance – including facilities managers, landlords, maintenance contractors, and duty holders managing health and safety compliance.
It covers heating, cooling, ventilation, water systems, and electrical installations, setting out how often each component should be maintained and inspected.
SFG20 helps ensure systems are maintained in accordance with relevant regulations, such as the Health and Safety at Work Act, COSHH, and ACoP L8 for Legionella control.
We provide specialist support in maintenance planning, Legionella risk management, and air hygiene services to help organisations implement SFG20 effectively.
While not legislation itself, SFG20 underpins compliance with statutory duties under UK health and safety law and is widely recognised by insurers and enforcement bodies.
