Integrated Fire, Security & AV For Premium Environments
We design, install and maintain the fire, security and AV in super prime London homes and in Dior's boutiques — one team from outline drawings through to aftercare, since 2008.

Siloed suppliers create design problems. Fire, security and AV usually arrive as three separate subcontracts, and the gaps between them land on the drawings — a detector pushed off the ceiling grid, a rack that no longer fits the cupboard it was drawn into. We hold all three in house, with our own project managers and our own engineers, so what the architect drew is what gets installed, down to sounder plates finished to match your switches. It's why Dior's facilities team ring us directly, and why maintained clients reach the engineer who installed their system rather than a call centre.

View ProjectDesign It Right, From Day One
We join projects at outline design stage — alongside your architect, interior designer and MEP consultant — so fire, security and AV are engineered in from the start, not squeezed in at fit-out. We insure what we specify, so no design liability lands on the main contractor.

Design
We sit at the table from the earliest drawings, alongside the architect, interior designer, MEP consultant and you as the end client — while room layouts and specialist requirements are still being decided.
Not every architect specifies aspirating detection like VESDA, or knows how a discreet AV rack routes through a listed building. Catching that at outline stage means the right decisions go into the fit-out drawings once, rather than getting reworked on site.
Our design consultation carries its own design indemnity insurance, so a main contractor takes on no design liability for anything we specify.

Install
Because design and install sit under one roof, nothing is lost in translation between drawing and site. The engineers on your project are J-Tech's own — not a subcontracted crew working from someone else's spec.
First fix, containment, equipment fit and commissioning follow the design signed off at outline stage, so snagging is the exception, not the routine.

Maintenance
Fire, security and AV systems degrade quietly — a drifting detector or an untested backup battery rarely announces itself until it matters. Our maintenance programmes are scheduled around your building, not a generic annual tick-box visit.
Because the engineer on your maintenance visit likely installed the system, or works from the same as-built records, faults get diagnosed faster and fixed properly first time.

Aftercare & Ongoing Support
A system is only as good as the support behind it once it's live. Maintained clients get 24/7 access to J-Tech direct, not a third-party call centre relaying messages back to us.
As your building evolves — a new tenant fit-out, an extension, a change of use — we're already on file with the original design intent, so upgrades extend the existing system rather than starting again from a survey.





Safety Isn't Expensive — It's Priceless.
The Same Standard On Every Site
One home, a portfolio of stores, or a system that needs bringing up to date — the work is held to the same standard. Our own engineers, floors protected before anyone starts, cable routes agreed before anyone drills, and the same faces back for the service visit. That is what keeps a building safe long after the fit-out photographs are taken.
