About Decomi

A London-based team working on Wi-Fi and local network setups since 2013.

Decomi started in 2013 as a small operation focused on a narrow problem: homes and offices in London with routers plugged in but signal that never reached the back rooms. The founder, an electronics engineer who had spent several years fixing office network faults for a facilities contractor, decided there was room for a service that dealt only with wireless coverage, cabling and router configuration — not broadband sales, not hardware retail, just the setup work itself.

Thirteen years later the company is still built around that same narrow focus. The team has grown to six people, each handling site visits, cabling or configuration work across six areas of the city. Over that period the company has completed 1,652 jobs for 1,014 clients, and 238 of them have come back for a second project — usually after moving flat, extending a lease on a new office, or adding a garden room that needed its own access point.

Why the company exists

The mission is straightforward: make sure a wireless or wired network actually reaches every room it needs to, and make sure the person paying for it understands what was done and why. Too many network problems in older London properties — thick party walls, basement flats, converted terraced houses — get patched with a supermarket range extender rather than solved properly. Decomi's approach is to look at the building first, then choose equipment and placement to match it, rather than selling a fixed package regardless of the property.

The longer-term view is less about growth targets and more about staying useful to the same six areas the company already knows well. Familiarity with local building types — Victorian terraces in Islington, ex-council blocks near the Thames, small office conversions around Kings Cross — means fewer wasted visits and fewer wrong guesses about where a signal will or won't travel.

What guides the day-to-day work

• Diagnose before quotingEvery job starts with a walk-through or a phone conversation about the layout, not a fixed price sheet applied blindly.
• Plain explanationsClients get told what a mesh node does, why a cable route was chosen, and what the settings on the router mean, in ordinary language.
• Work that lastsCabling is labelled, configurations are documented, and settings are left in a state the client (or a future technician) can understand without guesswork.
• Local knowledgeSix years of coverage across the same six London districts means recurring building types are already familiar, which shortens survey time.

Where the expertise comes from

The team's background is mixed on purpose: some came from telecoms cabling work, others from IT support desks handling small business networks, one from building services. That mix means a job rarely needs a second visit from a different specialist — cabling, wireless configuration and basic network security are usually handled by the same person on site. Roughly 78 clients a year work with Decomi, a volume that stays manageable enough for the same small team to keep handling every visit personally, without subcontracting to unfamiliar technicians.
