Hospital and healthcare sprinkler systems

What is different about hospitals and healthcare
Annex A of BS EN 12845 puts hospitals at Ordinary Hazard Group 1, the same as offices and hotels, and on fire load that is about right. What makes healthcare different has nothing to do with the classification. It is that a hospital does not evacuate. It moves people sideways, through fire compartments, at the speed a bed and a ventilator allow, which changes what the fire protection is being asked to buy.
-
The system buys time for horizontal evacuation
Healthcare buildings are designed around progressive horizontal evacuation: patients move into the next compartment rather than out of the building. That strategy only works if the fire stays small and the compartment holds. Suppression is one of the things holding up that assumption, which is why a defect on a hospital system is a different conversation from a defect in a warehouse.
-
Isolation is planned around clinical activity, not around us
BS EN 12845 says only one zone should be down at a time, for the minimum time, and that shutting down a life safety installation should be avoided wherever possible. In a hospital that is not a guideline, it is the constraint the whole visit is built around. Theatres, critical care and imaging each have their own answer, and the plan is agreed with the estates team and the fire officer before anybody brings a tool.
-
Water where water is a hazard
Electrical switchrooms, imaging suites, server rooms and some laboratories are places where a discharge causes its own incident. These are design decisions about what is protected by suppression and what is protected by other means, taken area by area, and they need recording so the next person does not read an unsprinklered room as an omission.
-
The record gets read by more people than anywhere else
An authorising engineer, a fire officer, an insurer and an internal audit can all ask for the same file in a year. A complete log with dated defects and dated closures is worth more at that moment than any amount of recent work, because it shows a regime rather than a reaction.

Hospitals and healthcare: questions
Are sprinklers a legal requirement in hospitals?
There is no blanket rule that every hospital must have them. What decides it is the fire strategy for the building, the Building Regulations position on the work being done, and often the insurer. Healthcare buildings lean heavily on compartmentation and progressive horizontal evacuation, and suppression is one of the measures that can support or extend that strategy. Where a system already exists, the duty to maintain it is not optional.
How do you service a system in a ward that cannot close?
By planning it with the estates team well in advance and taking the smallest piece at a time. The non-intrusive checks happen around the ward round. The work that needs isolation is scheduled zone by zone, kept as short as it genuinely takes, and the ward knows what its fire strategy is operating on while it is down. Critical areas get their own plan rather than being fitted into a general one.
We have no record for the system we inherited. Where do we start?
With a survey rather than a quotation. A system nobody holds 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 and suction arrangement are in. You get that written down first, and it becomes the baseline everything afterwards is compared against.
What about areas where water would cause harm?
They are dealt with individually at design stage rather than by leaving them out quietly. Switchrooms, imaging suites and some laboratories are the usual cases, and the answer may be a different suppression medium, a different arrangement, or protection of the surrounding areas instead. The important part is that the decision is recorded, so an unsprinklered room reads as a design choice rather than as something missed.
Worth reading first
- Sprinklers Sprinkler servicing intervals under BS EN 12845 BS EN 12845 sets a weekly check the site can do itself, a quarterly flow switch and alarm test, and an annual service that includes the pump run under flow.
- Compliance What your insurer actually wants from a sprinkler system Insurers price a sprinkler system as risk mitigation only if they can trust it. LPCB approval of the contractor and an unbroken maintenance record are the two things that make it count.
- Compliance BS EN 12845, in plain English BS EN 12845 is the European standard for the design, installation and maintenance of fixed fire sprinkler systems in commercial and industrial buildings. It is the document that sets the weekly, monthly, quarterly, half-yearly and annual routines a UK sprinkler system has to be kept to.

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.
Approved, and audited on a schedule.
Two certifications, and the first one is the reason we could apply for the second. ISO 9001 is a precondition for LPCB approval, so this is a sequence rather than a collection.
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.
LPCB approved
Loss Prevention Certification Board
The approval UK insurers look for on sprinkler work. A system installed by an LPCB approved contractor counts as genuine risk mitigation on your policy; one installed by anybody else may not.
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.
Tell us the building. We will tell you what it is due.
No survey fee to find out where you stand. Describe the site and we will tell you which intervals apply and what the visit involves.
