If you run a hotel or a care home, you know that your responsibility doesn’t end when your guests or residents close their eyes for the night. In fact, that’s when your responsibility is at its highest. In the fire safety world, we call these "sleeping risk areas," and the rules around how we protect them have just taken a massive leap forward.
The British Standard BS 5839-1:2025 is now the benchmark for business fire alarm systems across the UK. It’s not just a minor tweak to the old rules; it’s a significant update designed to address how people behave (and how technology has improved) since the last major update in 2017.
At JKE Fire & Security, we’ve been busy helping our clients navigate these changes. If you’re wondering whether your current system is still up to scratch, or what you need to do for your next refurbishment, here is a straightforward guide to what’s changed and why it matters for your premises.
What is a "Sleeping Risk Area"?
In plain English, a sleeping risk area is any room where people sleep who aren't in their own private, permanent home. This covers:
- Hotels and B&Bs
- Residential care homes and nursing homes
- Student accommodation
- Hospitals and healthcare facilities
The reason these are treated differently is simple: when people are asleep, they are at their most vulnerable. Their senses are dulled, they may be disoriented when woken suddenly, and in the case of care homes, they may need physical assistance to evacuate.
1. Bedrooms are now "High Risk" (The L2 Shift)
Under the old standards, there was sometimes a bit of "grey area" about how much detection you needed inside a bedroom versus the corridors outside.
The 2025 update makes it crystal clear. If you have sleeping occupants, your building is now almost certainly classified as needing a Category L2 system.
In the past, an L2 system covered escape routes and "high-risk rooms" (like kitchens or boiler rooms). The 2025 standard now explicitly includes all sleeping rooms in that high-risk category. This means you can no longer rely on a smoke detector in the hallway to pick up a fire that started inside a guest room. Every bedroom needs its own automatic detection to ensure the earliest possible warning.
2. Moving Away from Heat Detectors
For years, many hotels installed heat detectors in bedrooms to avoid "nuisance alarms" caused by steam from showers or hairspray. While this reduced false alarms, it also slowed down the response time, and in a life-safety situation, every second counts.
BS 5839-1:2025 strongly favours smoke or multi-sensor detectors in all sleeping areas. Heat detectors are no longer the "default" choice. In fact, you can now only use them if a Fire Risk Assessment specifically justifies it.
Most modern systems now use multi-sensor technology (which looks for both heat and smoke patterns). These are incredibly smart, they can tell the difference between a burnt piece of toast and a genuine fire, giving you the best of both worlds: fewer false alarms and faster life-saving detection.
3. Mandatory Remote Monitoring for Care Homes
This is a big one for our clients in the healthcare sector. If you run a residential care home, simply having a loud siren isn't enough anymore.
The 2025 standard introduces "unacceptable variations." One of these is failing to provide automatic signalling to a Monitoring Centre (ARC). If your fire alarm triggers, it must automatically alert a professional monitoring station that can contact the fire brigade and keyholders immediately.
Why? Because in a care home, staff are often busy assisting residents. They might not be able to get to a phone immediately, or they might assume someone else has called it in. Automatic monitoring removes the "human error" factor. If you’re looking for Fire alarm systems UK compliance, this is a non-negotiable for care environments.
4. Visual Alarms and the "Vulnerable Occupant"
We are seeing a much heavier focus on Visual Alarm Devices (VADs), those flashing red or white lights you see near fire sounders.
The new standard places more responsibility on the "Responsible Person" (that's you, the business owner or manager) to ensure that everyone can be alerted. This includes guests or residents who are deaf or hard of hearing. If your fire risk assessment identifies that you might have people on-site who won't hear a standard siren, you need to have VADs in place, especially in bedrooms and bathrooms where they might be alone.
5. Zone Plans: No More Guessing Games
Imagine it’s 3:00 AM, the alarm is screaming, and your night porter is standing at the fire panel. The panel says "Zone 4, Circuit 2." Where is that? In a panic, every second spent looking for a map is a second wasted.
The 2025 standard makes Zone Plans mandatory for any multi-zone building. Omission of a clear, accurate zone plan (right next to the control panel) is now classed as a serious failure in compliance.
At JKE, we don't just install the hardware; we ensure your documentation is as professional as your detection. We can help you create clear, easy-to-read zone plans that mean your staff, and the fire service, know exactly where to go the moment an alarm triggers.
6. The "Logbook" and Maintenance Trap
Documentation has always been important, but the 2025 update puts it under a microscope. You are now required to maintain a detailed fire safety logbook that records:
- Every weekly test (yes, every single one!)
- Every false alarm (and what caused it)
- Every maintenance visit
- Any variations from the British Standard
If you don't have a robust maintenance contract in place, you are essentially flying blind. Regular servicing isn't just about ticking a box for the insurance company; it’s about ensuring that when that detector in Room 204 finally sees smoke, it actually works.
Do I Need to Replace My Whole System?
The short answer is: Not necessarily.
The BS 5839-1:2025 standard is not fully retrospective. If your current system was installed to the 2017 standards and is working perfectly, you don't have to rip it out tomorrow morning.
However, the "triggers" for an upgrade are:
- Refurbishments: If you are renovating rooms or extending the building, the new work must comply with the 2025 standards.
- System Failures: If your old panel dies and needs replacing, you should use that opportunity to bring the rest of the system up to date.
- Fire Risk Assessment (FRA): If your latest FRA identifies a gap in your "sleeping risk" protection, you have a legal obligation to fix it.
How JKE Fire & Security Can Help
