Fire, security & ventilation
in London.
Gemini AMPM has been working across Greater London since 1997: commercial fit-outs in the City and West End, NHS estates, residential towers, listed buildings and data centres. Our engineers are within reach of every London postcode and travel daily for surveys, planned maintenance and out-of-hours installs.
Within 75 min from our Burgess Hill HQ.

Same-team accountability across every visit: from the initial survey through install, commissioning, planned maintenance and out-of-hours reactive cover. Talk to us about your building.
Seven service lines,
one accountable team.
Fire Systems
Fire alarms and evacuation, AOV smoke extract, disabled refuge and PAVA. Designed, installed and maintained to current British standards, with monitored response when the alarm actually sounds.
Passive Fire Systems
Fire doors, fire stopping, compartmentation, barriers and risk assessments: the protection that works without anyone pressing a button.
Security & Access Control
Intruder alarms, CCTV, access control, door entry and 24/7 monitoring: the systems that stay awake after the last person leaves.
Ventilation & Air Quality
AHU and ductwork install, service and repair, fire-damper testing, ventilation hygiene, AOV smoke extract, air conditioning and commissioning.
Gas Suppression Systems
Inert and chemical gas suppression: design, install, repair and maintenance for data centres, comms rooms and irreplaceable assets.
Small Works & Project Remedials
The remedial actions, snags and small projects that close out a compliance report, handled quickly, by the team that already knows the building.
Mechanical & Electrical Services
Mechanical and electrical services that tie the life-safety and building systems together: power, distribution and supporting M&E.
