Or by building type
- BS EN 12845 Warehouses and distribution Racking, storage height and what you keep in it decide the design. Get those wrong and the system is under-designed from day one.
- BS 9251 Blocks of flats Above 11 metres a new block needs them. Everything after that is the maintenance record, and it is what a managing agent gets asked for.
- BS 9251 Care homes A building full of people who cannot self-evacuate, on a maintenance regime that has to be provable without disrupting them.
- DfE Technical Manual Schools and colleges The DfE stopped pointing at BB 100 in January 2026. What replaced it sets a height threshold, three building types that always qualify, and a maintenance regime for everything already installed.
- BS EN 12845 Offices Multi-let buildings where the landlord holds the common parts and the tenant holds the demise. Most of the trouble is the line between them.
- BS EN 12845 Museums and galleries The objection is always water on the collection. The arithmetic runs the other way, and it is worth seeing why before the decision gets made for you.
- BS EN 12845 Cinemas and theatres Ordinary Hazard Group 4, the highest of the ordinary groups. Most people assume an auditorium is a low risk. The standard does not.
- BS EN 12845 Hospitals and healthcare Ordinary Hazard Group 1, and the only building type on this list where nobody can be asked to leave. Isolation planning is the whole job.
- BS EN 12845 Cancer treatment centres A hospital classification wrapped around rooms no general contractor should touch: MRI, radiotherapy bunkers and aseptic pharmacy.
- BS EN 12845 Food processing Three different hazard groups live under this one heading. Which one you are in depends on what you make, not on the size of the shed.
- BS EN 12845 Shopping centres Ordinary Hazard Group 3, and a building whose design changes every time a unit is re-let. The system rarely keeps up on its own.
How it starts
- Survey Free, no obligation. We walk the building and find what is actually there.
- Fixed price in writing With the standard named and the intervals listed, so it can be compared.
- First visit Done, recorded, certificated. The record starts clean from day one.
Certified, and audited on a schedule.
ISO 9001, certified by BRE Global and accredited by UKAS. Somebody independent audits how every job is planned, recorded and signed off, on a schedule.
ISO 9001:2015
Certified by BRE Global, accredited by UKAS
An audited quality management system. It means the way a job is planned, recorded and signed off is itself inspected by somebody independent, on a schedule.
Working to BS EN 12845, BS 9251 and BS 9990. If your insurer or fire risk assessor wants the certificates themselves, ring us and we will send them over.
Before you pick a service
Do you do all of this yourselves?
Yes. Water-based fire suppression is the whole business: sprinklers, tanks, pumps and risers. We do not sell alarms, extinguishers, fire doors or gas suppression, and we do not subcontract the work on this page to somebody else. If a job needs a trade we do not have, we will say so rather than take it and manage it badly.
Can one contract cover several of these?
Yes, and it is usually the cheaper way round because the visits share travel and setup. One renewal date, one certificate format and one set of records, instead of three contractors issuing paperwork three different ways for your fire risk assessor to reconcile.
We do not know what our building has. Where do we start?
With the survey, which is free and carries no obligation. We walk the building, find what is installed, and tell you what the standard asks of it. Plenty of the buildings we take on have a system nobody has a drawing for, and that is a normal starting point rather than an awkward one.
Can you take over a system somebody else installed?
Yes, and most of our maintenance work is exactly that. There is no technical or legal tie between whoever installed a system and whoever maintains it. What matters is getting the logbook, the certificates and the as-fitted drawings handed over, and we will tell you what to ask for.

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.

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.
