QSD is a market leader in the installation of residential and domestic sprinkler systems which are designed and installed to meet BS 9251:2021. We have installed sprinkler systems in all sectors of the residential and domestic market place and our team of knowledgeable technical experts are available to advise you on your project from the earliest of planning stages.
Residential and Domestic Fire Sprinkler Systems
We use only the best quality CPVC pipework in our installations we use concealed sprinkler heads which are installed flush to the ceiling. When the sprinkler head operates, the flow of water in the pipework operates a flow switch which in turn operates an alarm system. The flow of water is small and typically much less than water used by Fire and Rescue Services.
In contrast to the myth sprinkler heads do not accidentally go off and are only triggered by a real fire. They are also extremely reliable and only 1 sprinkler in 16,000,000 exhibits any form of a manufacturing defect.


All our fire sprinkler systems are designed in-house by our qualified design engineers and are compliant with BS 9251: 2021. Each sprinkler system design is bespoke to each project and our designers take into consideration the appropriate sprinkler head location for fire protection as well as being sympathetic to the visual look of the ceiling.
QSD works alongside developers, architects, water companies, landlords, care providers, and homeowners. We can liaise with your local authority, and building control department to ensure your sprinkler system design is of the highest quality, and bespoke to your project.
Our installers are familiar and experienced with the variety of installation techniques required for different installations. We pressure test our systems after completion of 1st fix to check for leaks. On commissioning the system at the 2nd fix we provide all certifications and full training on using the system is provided.
Fire Sprinkler System Service and Maintenance
It is a requirement of BS 9251:2021 that residential and domestic sprinkler systems are serviced and maintained annually. All services completed by QSD are completed by one of our competent and qualified team members. The cost of a service varies based on the size and complexities of the project please contact us for a competitive service quotation.
Our fire sprinkler maintenance check includes inspection of the heads to ensure they are fitted correctly, there are no signs of leakage, that the head still covers the protected area, an inspection of lagging (if applicable), inspection of pump (if applicable) and inspection of tank (if applicable). We also complete a full commissioning test and provide a certificate for the service along with signing to verify the service in the system log book. In the unlikely event the system fails the inspection or requires remedial work, a full report will be issued along with a full quotation.

Common Questions
A fire sprinkler system is a network of piping charged with water either from a water main or a fire pump and tank. Fire sprinkler heads are connected to the pipework in the areas to be protected.
There are two types of fire sprinkler head, pendant or concealed, either can be wall or ceiling mounted.
CPVC is an engineered thermoplastic piping that does not support fire, and will only char when subjected to flame. In fire conditions, it performs superbly, and it has a twenty year proven track record for this application.
Supplied pump sets and valve groups are bespoke. This ensures that each fire sprinkler system has a pump set or valve group designed and built for its particular requirements.
All components are approved and tested and carry manufacturer’s warranty. Once assembled, they are fully tested in our workshop before being taken to the site.
Fire sprinklers are generally installed within the heated envelope of a building and should not require frost protection.
Frost protection will be required for pipe work, fittings and pump sets when they are likely to be exposed to temperatures below freezing, this may be an outhouse, garage, porch, sheds and even loft spaces.
