SFG20 is the standard maintenance specification for building engineering services. It is recognised as the industry standard and is an essential tool for planned maintenance. It is the benchmark for working standards; providing building owners, managers, contractors, consultants and end users with the tools to keep buildings properly maintained and compliant. SFG20 is made available through a dynamic web-based service which is updated in real-time.

SFG is the 'Service and Facilities Group', a specialist group within the Building Engineering Services Association who own and are responsible for the up-keep of the standard.

SFG20 is a growing library, providing over 400 industry maintenance task schedules covering all principal types of heating, cooling and ventilation, installation and plant, and electrical services complete with technical updates and legislative references.

The technical committee is comprised of Directors, Head of Groups and Senior Management representatives from CIBSE, BIFM, Bilfinger, Faithful + Gould, N G Bailey, Bouygues and other leading BESA practitioners.

These leading industry experts review SFG20's core library on a monthly basis to continually assess the effects of new legislation, equipment and changes to best practice. Any updates and amendments are then communicated to subscribers by way of technical bulletins and schedule updates, keeping our subscribers informed with regards to the latest legislation and best practice - keeping you compliant.

SFG20’s technical consultants continually monitor and review all legislation and best practice to ensure our library of maintenance tasks are up-to-date. Subscribers receive automatic change notifications via email.
