A domestic sprinkler commissioning certificate records that a residential sprinkler system has been installed and commissioned to BS 9251, the standard for sprinkler systems in domestic and residential occupancies. It captures the system category, the design criteria the system was engineered to and the flow and pressure results proving it will perform.
Sprinklers are increasingly a legal or building control requirement rather than an optional extra: all new and converted dwellings in Wales need them, as do new blocks of flats over 11 metres in England, and many care settings. Building control and fire authorities expect commissioning evidence before sign-off, and the certificate is that evidence.
TradePlanr lets you complete the certificate on your phone or tablet as you commission: record the water supply, tank and pump details, log the flow and pressure at the most remote head, confirm the alarm operates and produce a branded PDF for building control and the client.
Sprinklers are mandatory in all new and converted dwellings in Wales, and in new blocks of flats over 11 metres in England, with commissioning evidence expected before building control sign-off.
They are commonly required in care homes and other residential care settings, and are often imposed as a building control or fire engineering condition on loft conversions, large open-plan layouts and buildings with compromised escape routes.
Where a sprinkler system is part of the fire strategy, the commissioning certificate is the document that proves the installed system meets the BS 9251 design, so it should be issued at handover and kept with the building's fire safety records.
Record the address, client and your company, then log the BS 9251 category, water supply arrangement, tank and pump details where fitted, and the sprinkler head types installed.
Capture the design density, design area and the hydraulically most remote head, so the test results can be judged against what the system was designed to deliver.
Log the flow and pressure achieved at the most remote head, test the flow switch and alarm, and confirm the system is leak-free with the stop valve labelled and accessible.
Confirm the user information has been provided and the client knows how the system works and what not to do to it.
Capture the signatures, then generate a branded PDF for the client and building control and keep a copy on file against the job.
TradePlanr generates this and 45+ other gas, electrical, oil, plumbing and renewables certificates as proper PDFs — filled on site, signed on screen and stored against the job. Works even with no signal. Free to start.
All new and converted dwellings in Wales must have sprinklers, and in England new blocks of flats over 11 metres require them. They are also common in care settings and are often a building control condition on conversions and open-plan designs.
BS 9251 defines categories of system based on the occupancy risk, from Category 1 for ordinary dwellings up to Category 3 for higher-risk residential buildings. The category drives the design criteria, and the certificate records which one applies.
Proving the installed system delivers its design: measuring flow and pressure at the hydraulically most remote head, testing the flow switch and alarm, checking for leaks and confirming the stop valve is labelled. The certificate records each result.
