iMist Ltd.

Water mist fire suppression designed, built and serviced in-house

iMist Ltd. is a UK company specialising in high-pressure water mist fire suppression systems, positioned as a modern alternative to conventional fire sprinkler systems. The company states that it has been operating for over a decade and reports more than 14,000 installations across the UK. Its activity covers the full cycle of the product: system design, manufacture, installation and ongoing servicing, all handled by its own teams rather than subcontracted.

According to its own presentation, iMist describes itself as the market leader in protecting lives and property with these systems, a claim the company attributes to its own positioning rather than to an external ranking.

How the system differs from traditional sprinklers

The core proposition is water efficiency and reduced collateral damage. iMist states that its system uses up to 80% less water than traditional fire sprinklers, which limits water damage when activated, and that it does not require any stored water. The company also highlights a discreet, space-saving design intended to blend into modern interiors with minimal ceiling clutter.

On installation, iMist claims its system can be fitted up to 30% faster than traditional sprinklers and 50% faster than other mist systems. Maintenance is presented as low, with the in-house team managing design, installation and annual servicing, and dedicated project managers assigned to each job.

Building types and project categories covered

The company organises its work around a broad set of property types, which gives a clear picture of where its systems are applied:

• Single dwellings, including houses, open-plan and modern living layouts, home extensions and loft conversions
• Apartments and flats, multiple houses and multiple dwellings
• Student accommodation, hotels and hostels, and HMOs
• Heritage and listed buildings, and modular buildings
• Care homes and assisted living or sheltered housing
• Change of building use and retrofit solutions
• Social housing

iMist states that installations range from single homes and loft conversions to full modular developments, student accommodation and care homes.

Innovation and testing claims

iMist presents a series of industry firsts in the UK water mist segment. It reports being the first to carry out lithium-ion battery testing with water mist, using an electric bike as the test scenario; the first to test minimal sound transfer between flats to preserve privacy after installation; the first in the industry to test pipework fire-stopping compliance with fire-stopping material; and the developer of integrated downlight nozzles that combine high-pressure water mist with a clutter-free ceiling design.

The company also states that its systems have demonstrated a 100% success rate in live fire scenarios. Its Lumi-Plugin® accessory is described as combining downlights with other ceiling-mounted features to reduce ceiling clutter, an innovation the company presents as unique to iMist.

Warranty, servicing and aftercare

Every iMist system includes a 10-year warranty when serviced annually, alongside a fully managed service that runs from design and installation through to sign-off and annual servicing. The company states that its servicing prices have remained unchanged since 2015. Separate aftercare lines cover servicing and maintenance, warranty registration and a monitoring system.

Accreditation, training and professional outreach

iMist describes its water mist systems as among the most rigorously tested and accredited in the UK, with continuous testing and regular audits, and states that it is endorsed by Which? and holds Which? Trusted Trader status. The site also carries a Trustpilot rating shown as excellent at the time of writing this profile.

The company runs free CPD sessions led by its CPD Manager, Eddie Sibley, whose background is as a firefighter. The sessions cover the benefits of water mist fire suppression and address questions such as the importance of test evidence and accreditation, how mist systems and sprinklers differ, how mist suppresses fires and which properties are suitable. iMist states that over 5,000 professionals have already taken part and that sessions can be arranged at a convenient date.

Compliance guidance and quoting process

Alongside the product, iMist publishes compliance and advice material covering UK fire safety regulations for England, Scotland and Wales, plus accreditations and approvals. Prospective clients can request a free, no-obligation quote by sending floor plans through the site's form; the company indicates that it will still follow up with clients who do not have plans available.
