What does TM Services do?
We support residential and commercial fire suppression projects through specification and design coordination, installation, commissioning, handover and maintenance. Explore our services.
Do you work on both homes and commercial properties?
Yes. Residential and commercial projects are assessed against their own occupancy, fire strategy and appropriate system evidence. See our commercial work.
What information do you need for an estimate?
Please send the full property address, your contact details, floor plans or reflected ceiling plans, the project type, and any available fire strategy or Building Control requirements. Prepare an enquiry.
Can water mist be used in an open-plan home?
It may form part of an appropriate fire strategy, but suitability and any approvals are project-specific. Share your plans and the relevant fire strategy so the proposed approach can be assessed.
Which standards do you use for new residential water mist projects?
Our approach uses BS EN 14972-1:2020+A1:2025 with manufacturer fire-test evidence to BS EN 14972-17:2025 for the selected system and application. Read the standards guide.
Does every project use the same nozzle spacing?
No single spacing rule should be applied to every system and room. Nozzle model, ceiling geometry, obstructions, tested limits and the project design all matter.
Will my system need a water tank?
Water supply arrangements depend on the selected system and project design. We assess the available supply and required performance before confirming the configuration.
How visible are the new iCO nozzles?
The current iCO HP MK2 and LP MK1 use concealed cover finishes. Their published datasheets describe a cover approximately 6 mm below the ceiling. View the products and datasheets.
Can you maintain an existing iCO system?
Send us the property address, model details, installation date and available service records. We can review the installation and discuss suitable maintenance support.
How often should an iCO system be serviced?
Arrange annual servicing in line with the applicable manufacturer instructions and your system documentation. Automatic self-tests do not replace professional servicing. Explore maintenance options.
What areas do you cover?
We are based in London and serve projects across London and the South East. For a project further afield, contact us with the location and scope to discuss availability.
Can I book an installation date straight away?
The programme depends on the agreed scope, design and approval requirements, site readiness and order arrangements. We will confirm the next steps and availability for your project.
