TL;DR: Fire alarm PPM (planned preventative maintenance) is a scheduled programme of inspection, testing and servicing that keeps a commercial fire alarm system working reliably and keeps the building compliant with UK fire safety law. In practice it means at least two professional service visits every 12 months, roughly every six months, carried out to BS 5839-1:2025, plus your own weekly manual call point test and daily panel check. A PPM contract puts all of that on a fixed schedule so nothing gets missed. Elmstone Fire runs BAFE-registered fire alarm maintenance and PPM contracts across Kent, Medway, London and the wider South East, backed by 24/7 emergency call-outs.
If you own or manage a commercial building, you have probably seen “PPM” on a quote or a contract and wondered what you are actually paying for. Is it just someone popping in to press a few buttons twice a year, or something more? And do you really need a contract, or can you sort servicing out as and when you remember?
This guide clears it up. We explain exactly what fire alarm PPM covers, how often visits should happen, what a good contract includes, roughly what it costs, and how to tell a proper planned programme from a box-ticking exercise. It is written for property owners and facilities managers across the South East who want their alarm to work on the one day it really matters.
What is fire alarm PPM?
Fire alarm PPM stands for planned preventative maintenance. It is a fixed, scheduled programme of inspecting, testing and servicing your fire detection and alarm system so faults are caught and fixed before they cause a failure, a false alarm or a compliance breach.
The word that matters is preventative. Reactive maintenance waits for something to break and then fixes it. Preventative maintenance works to a calendar, checking the panel, detectors, call points, sounders and batteries on a set rhythm so problems are spotted early. For a fire alarm, where the whole point is that it works instantly in an emergency, waiting for a fault to reveal itself is not a strategy you want to rely on.
A PPM contract simply formalises that rhythm. You agree a schedule of visits with a competent provider, they turn up on time, they service the system to standard, and you get the certificates that prove it. No chasing, no forgetting, no gap in your compliance record.
What does a fire alarm PPM visit actually include?
A proper PPM service visit is a full functional check of the system, not a quick look at the panel. Under BS 5839-1:2025, each visit should confirm the system is working as designed and flag anything that needs attention.
A competent engineer will typically:
- Check the control panel for faults, correct time and date, and healthy status indicators
- Test a sample of detectors and manual call points on a rolling basis, so every device is tested across the year
- Confirm sounders and any visual alarm devices operate at the right levels
- Check batteries and the standby power supply
- Inspect for changes to the building that affect coverage, such as new walls, stock or partitions
- Investigate recurring false alarms and recommend fixes
- Complete the service log and issue a service certificate
That last point matters more than people realise. The certificate and log book are your evidence of compliance. If a fire officer or insurer asks, that paperwork is what proves the system has been maintained by a competent person.
How often should fire alarm PPM happen?
Your commercial fire alarm system should be professionally serviced at least twice every 12 months, roughly every six months, in line with BS 5839-1:2025. The 2025 edition of the standard allows each visit to fall within a five to seven month window rather than an exact date, which makes scheduling far easier for busy sites with multiple contractors on the go.
Some higher-risk or larger premises benefit from quarterly visits, particularly where a single fault could shut a site down or where false alarms are frequent. Your fire risk assessment and provider should agree the right frequency for your building.
Professional visits are only half the picture. As the responsible person you also have day-to-day duties between visits:
| Check | Who does it | How often |
|---|---|---|
| Test one manual call point (rotating) | You or a nominated person on site | Weekly |
| Visual check of the panel for faults | You or a nominated person on site | Daily |
| Full inspection and service | Competent PPM provider | Every 6 months (5 to 7 month window) |
| Battery and standby supply checks | Competent PPM provider | At each service visit |
A good PPM provider sets this routine up for you, shows your team how to run the weekly test, and keeps the log book straight so nothing slips through the cracks.
Why does fire alarm PPM matter legally?
Because the legal duty sits with you, not your contractor. Under the Regulatory Reform (Fire Safety) Order 2005, the “responsible person” for a non-domestic building must keep fire safety equipment, including the fire alarm, in efficient working order. Six-monthly servicing by a competent person is the accepted way of demonstrating you have met that duty.
Skip it and the consequences land on your desk. Enforcement notices, a void insurance claim after a fire, and potentially unlimited fines all follow the responsible person, not the maintenance company. A planned PPM programme is the simplest way to show, on paper, that you have taken your obligations seriously and kept the system reliable all year round.
There is a commercial upside too. A well maintained system throws far fewer false alarms, which saves you the disruption, the evacuation downtime, and in some areas the charges brigades apply for repeat false call-outs.
What does a fire alarm PPM contract cost?
Costs vary with the size and type of your system, but as a rough guide a PPM contract for a small commercial site in the South East often starts from around 150 to 300 pounds plus VAT per year for two visits, with larger addressable systems and multi-site portfolios priced higher.
Watch what the number actually includes. The cheapest quote is rarely the best value once you factor in what happens when something goes wrong.
| PPM contract feature | Why it matters | Ask before you sign |
|---|---|---|
| Number of visits per year | Sets your baseline compliance | Is it two visits minimum to BS 5839-1:2025? |
| Call-out response | Downtime costs you money | Is 24/7 emergency cover included or extra? |
| Parts and minor repairs | Hidden costs add up fast | What is covered in the fee and what is billed separately? |
| Same engineers | Familiarity means faster fixes | Will the same team learn my site? |
| Certificates and log support | This is your compliance evidence | Do I get a service certificate every visit? |
A fixed-price contract with clear inclusions beats a cheap headline rate that nickel-and-dimes you on every part and call-out. If you want a deeper checklist, our guide on how to choose a commercial fire alarm maintenance company walks through the red flags in detail.
PPM vs reactive maintenance: which is right?
For a fire alarm, planned always beats reactive. The two are not really rivals, because a good PPM contract includes a reactive element (the emergency call-out) but wraps it inside a scheduled programme so you are not just waiting for failures.
Reactive-only maintenance leaves you exposed. You have no proof of regular servicing, faults sit undetected until the next real test, and you scramble to find an engineer when the panel starts beeping on a Friday afternoon. Planned maintenance flips that. You know when visits happen, you have a paper trail, and your provider already knows your site when an emergency does hit. That is why nearly every insurer and fire officer expects to see a planned programme rather than an ad-hoc one.
If a service visit turns up remedial work, such as ageing detectors or coverage gaps, a good provider handles it through their fire alarm remedial works service rather than leaving you to find someone else.
How to set up a fire alarm PPM contract
Setting up PPM is straightforward with the right provider. Start with a site survey so they can see your system, its age, its category and any quirks. From there you agree a visit schedule, a fixed price, and what is included, then the provider takes over the calendar and the reminders.
Choose a firm that is third-party accredited (ideally BAFE SP203-1 registered), works to BS 5839-1:2025, offers genuine 24/7 cover, and is local enough to reach you fast. Local response is a real advantage in the South East, where a provider based near Medway can reach sites across Kent and into London far quicker than a national call-centre operation.

Frequently asked questions
What does PPM stand for in fire alarms?
PPM stands for planned preventative maintenance. It is a scheduled programme of inspecting, testing and servicing a fire alarm system so faults are caught early, rather than waiting for the system to fail and fixing it reactively.
How often is fire alarm PPM required?
A commercial fire alarm should have PPM servicing at least twice every 12 months, roughly every six months, to comply with BS 5839-1:2025. The 2025 standard allows each visit within a five to seven month window. You should also test a manual call point weekly and check the panel daily.
Is a fire alarm PPM contract a legal requirement?
The Regulatory Reform (Fire Safety) Order 2005 requires the responsible person to keep the fire alarm in efficient working order. A contract is not named in law, but six-monthly servicing by a competent person is the accepted way to prove compliance, and a PPM contract is the simplest way to guarantee it happens.
What is the difference between PPM and reactive maintenance?
PPM is planned and scheduled to prevent failures. Reactive maintenance only responds after something breaks. A good PPM contract includes emergency call-outs, so you get the best of both: a scheduled programme plus fast response when you need it.
How much does fire alarm PPM cost?
A PPM contract for a small commercial site in the South East often starts from around 150 to 300 pounds plus VAT per year for two visits. Larger addressable systems and multi-site portfolios cost more. Always check whether call-outs, parts and certificates are included.
