Fire suppression systems — sprinklers, watermist, gas and kitchen suppression
A fire suppression system is engineered to control or extinguish a fire automatically at its source, before it spreads. We design, install and maintain the right suppression technology for the risk — automatic sprinklers and watermist for buildings, clean-agent gas suppression for server rooms and electrical risk, and wet-chemical systems for commercial kitchens. Every system is specified to the relevant British Standard, commissioned with a certificate, and kept compliant on a planned maintenance contract.
Fire suppression systems
Fire suppression systems should be specified around the building, risk, compliance requirements and day-to-day use. DC Fire & Security surveys the site, recommends the right approach and provides a clear no-obligation quote.

Who is this for?
For building owners, developers, facilities managers, restaurant and hotel operators, and data-centre and IT teams who need automatic fire suppression designed, installed and certified — whether to satisfy Building Regulations, an insurer requirement, or a fire risk assessment recommendation.
- Developers meeting Approved Document B sprinkler requirements in residential blocks over 11m
- Warehouse and logistics operators protecting high-piled storage
- Restaurants, hotels and commercial kitchens needing wet-chemical protection over cooking ranges
- Data centres, server rooms and comms rooms needing clean-agent gas suppression
- Care homes and sheltered housing where sprinklers support the evacuation strategy
- Manufacturing and plant with specific machinery or spray-booth fire risks
- Landlords and managing agents actioning a suppression recommendation from an FRA
- Insurers and brokers requiring an LPS-certified sprinkler installation
Fire suppression problems we resolve
- New residential blocks over 11m that now require sprinklers under Approved Document B but have no design in place
- Commercial kitchens with no fixed suppression over the cooking line — the single most common cause of catastrophic restaurant fires
- Server rooms and comms rooms protected only by a smoke detector, with no means of extinguishing a fire before hardware and data are lost
- Existing sprinkler systems that have never been serviced, with corroded valves, low water pressure or missing block plans
- High-piled storage or racking changes that have outgrown the original sprinkler design density
- Suppression systems installed by others with no commissioning certificate, block plan or O&M manual for the insurer
- Kitchen suppression cylinders past their service interval, invalidating the insurance cover
What's included in our fire suppression service
Risk-Based System Selection
We match the suppression technology to the hazard — sprinklers or watermist for general building protection, clean-agent gas for electrical and IT risk, wet chemical for kitchens — rather than forcing one solution onto every job.
Design to British Standard
Sprinklers designed to BS EN 12845 (and LPC/LPS rules where insurers require), watermist to BS 8489 / DD 8489, gas suppression to BS EN 15004, and kitchen systems to the manufacturer's LPS 1223-listed specification.
Hydraulic & Water-Supply Assessment
For water-based systems we verify the available flow and pressure, and specify tanks, pumps or mains upgrades where the supply is insufficient.
Clean-Agent Gas Suppression
Inert gas or chemical clean-agent systems (e.g. IG-55, FK-5-1-12) for server rooms and electrical spaces — extinguishing fire without water damage to equipment, with room-integrity fan testing.
Kitchen (Wet Chemical) Systems
Fixed suppression over cooking ranges, fryers and extract canopies, interlocked to cut gas and electrical supply on activation.
Commissioning & Certification
Every system is commissioned, flow/pressure or discharge tested, and handed over with a commissioning certificate, block plan and O&M manual for your insurer and fire risk assessment.
Scope of works
Our qualified engineers carry out the following as standard:

Fire Alarm Integration
We connect suppression release and flow switches to the fire alarm system so activation raises the alarm and, where required, shuts down plant.
Fire Risk Assessment
If your suppression need came from an FRA, we can carry out or update the assessment so the whole fire strategy is consistent.
Sprinkler Maintenance Contract
Weekly, quarterly and annual inspection regimes to BS EN 12845 keeping the system reliable and the insurer satisfied.
Emergency Lighting & Signage
Suppression works are commonly bundled with emergency lighting and escape signage to close out an FRA action plan in one visit.
Typical project timeframes
Key benefits
Ongoing support & maintenance
Planned Maintenance
Scheduled inspection and testing of sprinkler, gas and kitchen systems to the relevant standard, with certification for your compliance file.
Cylinder Service & Re-fill
We weigh, test and re-fill gas and kitchen suppression cylinders on their service interval so cover stays valid.
Reactive Call-Out
Response to faults, activations and post-discharge reinstatement to bring the system back into service quickly.
How it works
Risk & Site Survey
We assess the hazard, the building and the water/power supplies, and confirm which suppression technology fits the risk and the standard.
Design & Calculation
We produce the system design, hydraulic calculations or gas concentration calculations, and documentation for building control and your insurer.
Installation
Our engineers install pipework, heads/nozzles, cylinders, control valves and interfaces with minimal disruption to your operation.
Commissioning
We test the system — flow and pressure, discharge or room-integrity as appropriate — and interface it to the fire alarm.
Certification & Maintenance
You receive the commissioning certificate, block plan and O&M manual, and we set up the maintenance regime that keeps it compliant.
