SFG20 is the UK industry standard library of planned maintenance schedules for buildings, created in 1990 by the Building Engineering Services Association (BESA). For each asset type it sets out which maintenance tasks to carry out, how often, and with what skills, so owners and contractors can build PPM regimes from a recognised baseline instead of writing them from scratch.
What SFG20 contains
SFG20 is published as a subscription library, now accessed online, and is updated as legislation and industry practice change. Each schedule covers a type of asset, such as a chiller, fire alarm system, water tank or air handling unit, and sets out:
- The individual maintenance tasks, written step by step
- The recommended frequency of each task, to avoid both over- and under-maintenance
- The skill set required, for example mechanical, electrical or a specialist trade
- A criticality rating for each task, using a colour-coded scale
The colour-coded criticality ratings
The feature most people know SFG20 for is its colour coding, which separates what must be done from what is good practice. It is what lets an owner reduce maintenance spend without accidentally cutting a legal obligation.
- Red: statutory. Tasks required by law, which must be carried out at the stated frequency to stay compliant.
- Pink: mandatory. Tasks required for sector, organisational or business-critical reasons, even where the law does not demand them.
- Amber: optimal. Function-critical tasks and industry best practice that keep assets performing as intended.
- Green: discretionary. Non-critical tasks that can be adjusted to the owner's budget and risk appetite.
Why UAE and GCC contracts reference SFG20
Consultants writing FM tenders in the region need a published, recognised baseline for maintenance scope, and SFG20 is the one most of them know, partly because much of the region's FM practice was shaped by UK-trained consultants and contractors. Specifying it gives owners an auditable standard: bidders price the same scope, and the owner can challenge a contractor who quietly reduces frequencies.
The important caveat is that SFG20's statutory tasks are written against UK legislation. In the UAE, statutory obligations come from local sources such as the UAE Fire and Life Safety Code of Practice enforced by Civil Defence, municipality requirements, and sector regulators in areas like healthcare. Frequencies may also need adjusting for climate, since dust and summer heat affect filters, condensers and cooling towers more than a UK schedule assumes. Good contracts therefore specify SFG20 adapted for local statutory requirements, rather than SFG20 alone.
How SFG20 maps into PPM schedules in a CAFM
In a CAFM system, SFG20 schedules become PPM templates attached to asset types. Once each asset in the register is classified correctly, the system generates recurring work orders at the chosen frequencies, each carrying the relevant task checklist, skill requirement and criticality. Red and pink tasks are typically tracked and reported separately, because a missed statutory task is a compliance failure while a missed green task is a budget decision.
Two practical points decide whether this works. First, the asset register must be classified to match the schedules, which is where accurate asset tagging pays off. Second, SFG20 is licensed content, so owners and contractors need a valid subscription to use the schedules, and should confirm with their CAFM vendor how schedules are imported and kept up to date.
Common questions
What is SFG20?
SFG20 is the UK standard maintenance specification for building engineering services, created by BESA in 1990. It is a library of planned maintenance schedules that set out tasks, frequencies, skills and criticality for each type of building asset.
Is SFG20 mandatory in the UAE?
No. SFG20 is not a UAE regulation, and it becomes binding only when an FM contract or tender specifies it. UAE statutory maintenance requirements come from local authorities such as Civil Defence and the municipalities, and these take precedence where they set a different frequency.
What do the SFG20 colour codes mean?
Red tasks are statutory, pink tasks are mandatory for sector or business reasons, amber tasks are optimal best practice for function-critical assets, and green tasks are discretionary. The ratings help owners decide where maintenance can be reduced safely and where it cannot.
Is SFG20 free to use?
No. SFG20 is a paid subscription service. Some CAFM systems can import or link to SFG20 schedules, but the licence to use the content is separate from the software licence.
