What Is SFG20 (Building Maintenance Standard)? Facilities Management Definition and How Teams Use It

Quick Answer

SFG20 is the recognised standard for planned building maintenance in the UK, maintained by the Building Engineering Services Association. It provides a library of maintenance task schedules for building assets, each with a recommended frequency and a colour-coded priority, so facilities teams know what to service, how often, and why. Following SFG20 schedules and recording each completed task is how FM teams keep assets compliant and maintenance defensible.

What is SFG20?

SFG20 is widely regarded as the industry standard for planned preventive maintenance of building services, maintained and regularly updated by the Building Engineering Services Association (BESA). Rather than a single document, it is a live library of maintenance task schedules covering a broad range of building assets, from heating and ventilation to fire safety and electrical systems.

Each schedule lists the maintenance tasks for an asset type, the skill level required, and a recommended frequency, and tasks are colour coded by priority so teams can tell statutory and safety-critical work apart from routine or optimisation tasks. Because the content is kept current with changing regulations and standards, SFG20 gives facilities teams a defensible basis for deciding what maintenance to do and when.

What using SFG20 involves

In practice, using SFG20 means matching the assets in a building to the relevant task schedules, then building a planned maintenance programme from the recommended tasks and frequencies. Teams often tailor the schedules to their own assets and risk profile, keeping the statutory and safety-critical tasks while adjusting optional ones to suit the site.

The value comes from following the programme consistently and recording each completed task with evidence, so the maintenance history reflects the standard rather than habit. A complete record of what was done, when, and by whom is what lets an FM team show that assets have been maintained to a recognised standard if a client, insurer, or auditor asks.

How Inspectly360 supports SFG20-based maintenance

Inspectly360 turns SFG20-aligned maintenance schedules into recurring tasks on a planned programme, holding each asset on a register with its tasks and frequencies and prompting the team before work falls due. Maintenance visits run as mobile checklists with photo evidence and timestamps, so completion is captured at the asset rather than logged later.

When a task finds a fault, a corrective action is raised with an owner and a due date and tracked to a verified fix, and managers see completion rates and overdue tasks across every building on one dashboard. See the FM preventive maintenance software to run an SFG20-based programme and keep a defensible maintenance record.

Frequently Asked Questions

What is SFG20?

SFG20 is widely recognised as the standard for planned preventive maintenance of building services in the UK, maintained and regularly updated by the Building Engineering Services Association, known as BESA. It is not a single fixed document but a live, subscription-based library of maintenance task schedules covering a wide range of building assets, including heating, ventilation, air conditioning, electrical, and fire safety systems. Each schedule sets out the maintenance tasks for an asset type, the frequency they should be carried out, and the skill level needed. Because it is kept up to date with current regulations and standards, facilities teams use SFG20 as a defensible basis for deciding what maintenance is needed on their buildings and how often it should happen.

What do the SFG20 colour codes mean?

SFG20 task schedules use a colour-coded system to show the priority of each maintenance task, which helps teams distinguish work that is legally required from work that is good practice or optimisation. In broad terms, some tasks are marked as statutory or safety critical, meaning they relate to legal duties or to keeping people safe and should not be dropped, while others are important for reliability and efficiency but carry more flexibility on timing. This prioritisation lets facilities teams build a maintenance programme that protects compliance and safety first, then fits in the remaining tasks according to budget and risk. Used well, the colour coding stops safety-critical work being deferred when resources are tight, because it is clearly separated from tasks that can be rescheduled.

Is SFG20 a legal requirement?

SFG20 itself is a standard rather than a law, so an organisation is not legally obliged to use SFG20 specifically. However, there are legal duties to maintain building services and keep people safe, for example under health and safety and fire safety legislation, and SFG20 is one of the most widely accepted ways to show those duties are being met. Its task schedules identify the statutory and safety-critical maintenance that supports legal compliance, which is why many facilities teams, contractors, and clients adopt it as their reference standard. In practice, following an SFG20-based programme and recording each completed task gives an organisation a recognised, defensible basis for demonstrating that its building maintenance meets the expected standard.

How is SFG20 different from a CMMS?

SFG20 and a CMMS solve different parts of the same problem. SFG20 defines what maintenance should be done and how often, providing the standard library of task schedules and frequencies for building assets. A CMMS, or computerised maintenance management system, is the software used to plan, assign, track, and record that maintenance once it is under way. The two work together: an organisation takes the relevant SFG20 schedules, loads them into its maintenance system as recurring tasks against each asset, then uses the software to schedule the work, capture completion and evidence, and report on it. In short, SFG20 is the content and the standard, while the CMMS or inspection platform is the tool that turns it into a running, recorded programme.

How does Inspectly360 help with SFG20-based maintenance?

Inspectly360 helps facilities teams run an SFG20-based programme by turning the relevant task schedules into recurring maintenance tasks against each asset on a register, then prompting the team before work falls due. Maintenance visits run as mobile checklists with photo evidence and timestamps, so completion is captured at the asset rather than written up later, and statutory or safety-critical tasks can be prioritised in line with the standard. When a task finds a fault, the app raises a corrective action with an owner and a deadline and tracks it to a verified fix. Managers see completion rates and overdue tasks across every building on one dashboard, so the maintenance record shows assets are being serviced to a recognised standard rather than relying on memory or scattered job sheets.
