NPHS is the UK’s leading and largest water mist installer. We design, install, commission and maintain water mist fire suppression systems for domestic, residential, commercial and specialist projects across the UK.
Send us your drawings, specification or fire strategy and our team can review the building, water supply, relevant water mist standard, test evidence and installation requirements.
Water mist fire sprinkler installation for UK projects
NPHS designs, installs, commissions and maintains water mist fire suppression systems across the UK. Our work covers project review, system design, water supply, installation coordination, commissioning and handover documentation.
Water mist can provide highly effective fire suppression using dramatically less water than conventional sprinkler arrangements. Lower water demand can reduce plant requirements, pipe sizes and the volume of water discharged during an activation.
Compact equipment and discreet nozzles also make water mist well suited to retrofit projects, constrained plant areas, heritage buildings and high-finish interiors.
NPHS can become involved during specification or once drawings, a fire strategy or tender package are available. Specialist systems including Cease Fire, gaseous suppression and Ultra Fog can also be considered where the project risk calls for a different approach.

What is included in water mist fire sprinkler installation?
Water mist installation can include design coordination, compact pump equipment, pipework, water mist nozzles, valves, controls, water supply arrangements, testing, commissioning and handover documentation.
The final scope depends on the building, application, fire strategy, selected technology and agreed project responsibilities.
- Review project drawings, specification, building use and fire strategy
- Confirm the suitable water mist or specialist suppression route
- Review water supply, plant requirements, test evidence and installation constraints
- Coordinate pipework, nozzles, pump equipment, controls and interfaces
- Install the agreed system around the site programme
- Test the installed system and complete commissioning checks
- Provide relevant handover and system information
- Plan inspection and maintenance after completion
Early coordination gives the project team more options for nozzle positions, pipe routes, pump location and future service access. Smaller water mist pipework and compact plant can make coordination easier in buildings where space is limited.
Which fire suppression system is suitable?
NPHS starts with the building, fire risk, water supply, available space, test evidence and project approval route. Water mist is our primary installation specialism, with other specialist systems considered where the application requires them.
Water mist
Fine droplets provide effective fire suppression with substantially lower water demand. Compact equipment, smaller pipework and discreet nozzles can make mist particularly practical for retrofit, constrained spaces and finished interiors.
High-pressure and low-pressure mist
Different water mist technologies suit different applications. Selection depends on tested performance, hazard, building type, available water supply, space and the required system configuration.
Specialist suppression
Kitchens, equipment risks, technical rooms, machinery and other defined hazards may suit Cease Fire, gaseous suppression, Ultra Fog or another project-specific specialist system.
Water mist standards and compliance routes
Water mist systems need to be selected and designed around the relevant standard, application test evidence, fire strategy and project approval route.
BS EN 14972-1:2020+A1:2025 provides the current framework for the design, installation, inspection and maintenance of fixed land-based water mist systems.
BS EN 14972-17:2025 provides the residential occupancy fire-test protocol for automatic nozzle water mist systems. The selected product should have evidence that supports its intended application and configuration.
BS 8458:2015 was withdrawn by BSI on 7 July 2025. Withdrawal does not automatically invalidate products previously independently tested and certified against it. Existing certification can remain relevant supporting evidence when reviewed alongside current standards and the project requirements.
Approved Document B, the fire strategy, Building Control requirements and other project-specific conditions may also influence the compliance route. NPHS can provide technical information and system evidence to support that process.
| Reference | Where it may be relevant |
|---|---|
| BS EN 14972-1:2020+A1:2025 | Current framework for the design, installation, inspection and maintenance of fixed land-based water mist systems. |

| BS 8458:2015 | Previous UK domestic and residential water mist code. Existing independently tested and certified systems may continue to use it as supporting evidence. |
| System fire-test evidence | Confirms the application, nozzle arrangement, pressure, flow, ceiling height and other tested system limits. |
| Manufacturer design information | Defines the approved design parameters, equipment requirements and installation limits for the selected water mist system. |
| Approved Document B / project fire strategy | Can influence where suppression is required and how the project compliance route is evidenced. |
NPHS project check:
NPHS can support specification, installation, commissioning and documentation. Final project acceptance remains with the relevant appointed project and regulatory stakeholders.
Commercial, residential and specialist water mist installation
Water mist can be used across a wide range of buildings where suitable test evidence supports the application. Reduced water demand, compact equipment and smaller pipework can solve practical installation problems in both new-build and retrofit projects.
Commercial water mist installation
Offices, hotels, public buildings and other commercial properties can benefit from reduced water demand, compact plant and installation routes designed around existing services.
Residential developments
Flats, apartments, care, supported living and housing schemes can use discreet water mist systems designed around occupancy, fire strategy, test evidence and long-term management.
Domestic properties
Individual homes, open-plan layouts, extensions and loft conversions can benefit from compact pumps, discreet ceiling nozzles and reduced water demand where the system suits the project.
Retrofit and heritage projects
Smaller pipework, compact equipment and lower water demand can make water mist practical where plant space, ceiling voids, finishes or existing building fabric create installation constraints.
Specialist risks
Technical rooms, kitchens, plant, equipment and localised hazards may require water mist, gaseous suppression, Cease Fire, Ultra Fog or another specialist solution.
Domestic and residential projects are treated separately within the NPHS specification route. Building type, occupancy, fire strategy and test evidence determine the design approach.
Commissioning, handover and water mist system documentation
Commissioning confirms that the installed water mist system has been checked against the design before handover. It also provides a clear record for the contractor, consultant, client and future building management team.
Depending on the system and project scope, handover information may include:
- Final system drawings and installation information
- Nozzle, pump, valve and equipment data
- Water supply and operating information
- Testing and commissioning records
- Control and alarm interface information where relevant
- Operating and maintenance information
- Inspection and servicing requirements
- Defect or remedial information where required
Clear records make future inspection, maintenance, alterations and fault investigation easier. They also help preserve the design and test basis of the system when the building changes.
Fire sprinkler and water mist maintenance after installation
Water mist fire suppression systems need planned inspection and servicing after handover.
NPHS maintains the water mist systems we install and can also inspect, service and manage suitable existing traditional sprinkler systems.
Planned maintenance helps building managers maintain records, identify defects and check whether alterations to the building have affected coverage, equipment or system access.
Nozzles, heads and pipework+
Check visible condition, access, damage, obstruction and anything that could affect the intended discharge pattern.
Valves and controls+
Check relevant valves, controls, system indications and accessible operating components in line with the installed system requirements.
Pumps and water supply+
Review the water supply, pump equipment and associated components against the requirements of the installed system.
Changes to the building+
Review new partitions, ceilings, lighting, storage or other alterations that could affect coverage, nozzle discharge or service access.
Records and defects+
Document findings, defects, recommendations and completed maintenance work for the building record and future servicing.
