What is different about schools and colleges

School sprinkler systems usually come to us with a new build or major refurbishment under the DfE framework, a flagged fire risk assessment, or an inherited building with no maintenance record. Sentry Sprinkler Protection services sprinkler systems for schools and colleges, to the DfE Technical Manual, BS EN 12845 and BS 9251. For nearly twenty years the reference for fire safety in English schools was Building Bulletin 100, which expected sprinklers in most new schools unless a risk assessment showed otherwise. The DfE Technical Manual published in January 2026 states in terms that the use of BB 100 (2007 version) is no longer required, and sets its own rules instead. Those rules are narrower at the top and firmer underneath: fewer schools are caught, but the ones that are caught have no discretion left.

  • Four storeys or 11 metres, and three types that always qualify

    Automatic fire suppression is required in new buildings and in major refurbishment of existing ones where the building is at least four storeys and/or over 11 metres high, measured from ground level on the lowest side to the top floor surface of the top storey. Beyond that height test, three categories qualify whatever their size: buildings with residential accommodation such as boarding schools, and all Special Schools, Special Colleges and alternative provision.

  • It binds the framework, not the whole country

    The Technical Manual is the Employer's Requirements for the DfE Construction Framework 2025, so it governs projects procured through that route. It is not a change to the Building Regulations, and BB 100 has not been formally withdrawn. If you are building outside the framework, Approved Document B and your fire strategy are still what decide, and the Manual is worth reading anyway because it is where the specification argument will end up.

  • Installation needs two named installer certifications

    The Manual requires the system to be designed and installed by a specialist contractor holding two named third-party certifications for sprinkler design and installation. That is a narrow field, and it is worth checking a tenderer against it early rather than at award. We are telling you this rather than selling against it: our school work is the maintenance side, on systems already in the ground.

  • Schools are Ordinary Hazard 1, with a long list of exceptions

    The Manual classifies schools in general as OH1 and requires quick response heads, at least one superior single water supply, duty and standby pumps with automatic changeover, and the tank sited outside the building. It then carves out the places sprinklers should not go: science chemical stores, server and comms rooms, rooms with switchgear or transformers, and enclosed stairs and shafts. Where heads do sit near electrical equipment they need impact proof cages, with pipework kept off the gear.

Schools and colleges: questions

BB 100 said we needed sprinklers. Has that actually changed?

For projects procured through the DfE Construction Framework 2025, yes. The Technical Manual published in January 2026 says the use of BB 100 (2007 version) is no longer required, and replaces its risk assessed approach with fixed triggers: four storeys or over 11 metres, residential accommodation, and all Special Schools, Special Colleges and alternative provision. A two storey mainstream secondary that BB 100 would have expected to sprinkler is not required to under the new document. That change was publicly criticised by the Construction Industry Council and the Fire Protection Association, so expect it to be argued about rather than settled.

Our school already has a sprinkler system. What do we owe on it?

The same regime as any commercial system: the weekly and monthly checks that sit with the responsible person, and the quarterly, six monthly and annual routines that need a contractor. The Manual itself says systems shall be designed, installed and maintained in accordance with BS EN 12845, so the maintenance duty does not soften because the building is a school. Under the Regulatory Reform (Fire Safety) Order 2005 it sits with whoever controls the premises, which in practice means the trust or the local authority rather than the head.

Can you service a system that somebody else installed?

Yes, and that is most of what we do. It starts with a survey rather than a quotation, because a system nobody has a complete record for has to be established before it can be maintained: what is actually installed, what hazard class it was designed to, whether the pumps make their duty under flow, and what condition the tank is in. You get that written down and priced before anything is agreed.

What about the boarding house? Is that a different standard?

Usually yes. The Manual points residential accommodation at BS 9251 rather than BS EN 12845, and they are genuinely different documents rather than the same one with smaller heads: different design assumptions, different water supply rules and a different maintenance regime. A school estate with a boarding house can end up owing both standards on one site, which is exactly the situation where the two halves fall out of step and a fire risk assessor finds the gap.

The holidays are the only window we have. Does that work?

It works well, and it is when most school sprinkler work gets done. The parts that need the system isolated are the ones worth putting in a holiday; the non-intrusive checks can happen in term time without anybody noticing. What matters is booking it far enough ahead that the annual does not slide into a term, because a lapsed annual is the thing that shows up on the record.

Every interval and threshold on this page comes from one of these. Links go to the publisher, not to a copy of the document.

British Standards are copyright documents and most are bought rather than read free. We hold the ones we work to. If you need to know what one of them says about your building, ask us rather than buying it.

  • Lewis W. Sprinkler installation, warehouse

    Had them install a full sprinkler system across one of our warehouses, and couldn't be happier. They were professional from start to finish and the on-site team were genuinely friendly to work with. […] Highly recommend if you would need your building or warehouse properly fire-protected.

  • Mike C. Weekly maintenance, testing and repair

    Sentry Sprinkler Protection have recently taken over the weekly maintenance, testing and repair of the […] sprinkler equipment. They are providing a excellent service, good value and they are also very helpful when on site.

  • Sam E. Sprinkler pipework installation

    Couldn't recommend [Sentry] enough. Their work ethic, consistent efficient install of the pipework and overall approach to a project should be something every sub-contractor strives to mirror. Marius is incredibly approachable and methodical in his work with laydown areas kept very neat and tidy and all work carried out in a safe manner.
