sfgRecently, we have been getting a lot of questions from customers who are either thinking about or who are already using SFG20 to help maintain their smoke control systems. In this blog, we aim to answer some of the most common questions around what SFG20 is, how to use it and why it is beneficial.


What is SFG20?

Firstly, let’s look at what SFG20 is. The official SFG20 website explains it as such: "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.”

By providing you with access to a growing library of over 1,200 maintenance schedules that are updated as legislation changes, SFG20 enables you to stay compliant. The library of task schedules available covers all principal types of heating, cooling, ventilation, installation and plant, electrical services. It also allows you to create your own schedules if needed.

What does “SFG20” stand for?

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.

Originally launched in 1990, BESA's SFG20 is recognised as the industry standard for building and planned maintenance specification.

How does SFG20 help save you time and money?

Because SFG20’s technical consultants are continuously monitoring and updating all the legislation and best practice with regards to its library of maintenance tasks, you will never be unprepared for legislative changes.
