Thinking of installing fire sprinklers in your loft conversion, basement, or new build? You’re not alone!
Whether you’re a seasoned builder or tackling your first project, our Self Build Sprinkler Systems put professional-grade fire protection in your hands, with our expert support every step of the way.
We have seen a growing demand from DIY self-builders, and we’re proud to offer a bespoke design service tailored to your project. We give you full control, without compromising on safety or standards.
We provide a complete design, supply, and commissioning service, so you can confidently install your own system—on your own schedule, and with full peace of mind.
No Building Regs Permission Needed (In Most Cases): You don’t need building regulations approval to install a sprinkler system in areas like lofts or basements. However, any structural changes must still meet fire safety requirements. That’s where we come in,
Your self-build fire sprinkler system must be installed by someone trained and competent in residential sprinkler installation. They need a solid understanding of BS9251:2021 and the technical standards that apply to domestic fire protection.
GFS produces a full system design based on your architectural drawings. This includes pipework layouts, flow and pressure calculations, and all requirements needed to ensure the system performs correctly.
You (or your chosen installer) follow the design exactly as issued. Fire sprinkler systems rely on precision. Any alterations to pipe runs, heads, or fittings can impact water flow and the overall performance of the system.
During installation, GFS provides support and oversight to ensure the system is being fitted to the correct standard. We check compliance, verify quality, and highlight any issues that need addressing before testing.
When installation is complete, we test, commission, and sign off the system. Once fully compliant, you receive certification to BS9251:2021, confirming the system meets all required safety and performance criteria.
Your system needs a reliable water source. During design, we check:
Mains pressure and flow
Pump and tank options if required
Backflow preventers and connection points
We specify solutions that work with your site’s constraints so the system functions when needed.
A sprinkler system should work seamlessly with:
Electrical installations
Structural components
Insulation and finishes
Services routing
Careful planning keeps pipework discreet and avoids conflicts with other trades.
Your self build sprinkler system must fully comply with BS9251:2021, the British Standard for residential fire sprinkler systems. This standard dictates:
System design criteria
Installation methods and materials
Performance testing
Commissioning procedures
Maintenance and inspection schedules
GFS ensures every system we design adheres strictly to BS9251:2021 so your self build project is fully compliant and certified.
