Nineteen services. One accountable partner.

Cabling, fibre, security, electrical and commissioning delivered under one package — so the interfaces between them are our problem, not yours.

Why 369

The failures happen at the interfaces

Most critical-environment projects are not lost on any single trade. They are lost in the gaps between five of them, where nobody owns the join and everybody has a reason why it is not theirs.

Numbered patch panel with terminated copper cabling

The standard way to buy this work is to break it into trades and award each one separately. Cabling to the data contractor, containment to the electrician, access control and CCTV to the security firm, commissioning to whoever is left. Each package is competitively priced, each contractor is competent, and the scope on paper adds up to the whole job.

What it does not add up to is the joins. The cable tray that stops at the door of the room the cabling contractor has to get into. The access control head end that needs a data drop nobody priced. The commissioning window that assumed the power was live a week before the electrician had booked it. None of those are in anybody's scope, because each one sits between two scopes.

On an ordinary fit-out that costs you a variation and a fortnight. In a data hall, a rail station or a live ward, it costs you the programme, and the programme is the thing you cannot buy back.

Six places the join fails

None of these are hypothetical. They are the recurring ones, and they are all interface problems rather than trade problems.

01

Containment stops short

The tray is installed to the boundary of one scope and the cable has to cross a ceiling void that belongs to nobody. It gets resolved on site, informally, and the result is a pathway that fails inspection or a bundle sitting on a ceiling grid.

02

Power and data separation

Two contractors, two routes, one shared void. Separation is in both specifications and in neither work plan, and the problem only shows up as noise on a link nobody wants to own at certification.

03

Head ends with no drop

Access control, CCTV and intercom all need network connectivity. Security prices the devices, data prices the outlets, and the controllers in the comms room fall between the two. It is a small cost and a long delay.

04

Sequencing assumptions

Every trade's programme assumes something another trade has not committed to. Containment before racks, power before commissioning, network before witnessed testing. One slip moves everyone, and the arguments start.

05

Testing without a witness

Results get issued separately and late, in different formats, with nothing reconciling them to the asset register. The handover pack becomes a folder of PDFs rather than evidence anyone can act on.

06

Defects with no owner

At handover, a fault that crosses two scopes is investigated by neither. The client ends up coordinating their own subcontractors through a defects period they did not budget for.

What we do differently

Not better trades. The same trades, with the joins owned by someone.

One scope, one accountability

Cabling, fibre, containment, electronic security, electrical and commissioning delivered under one package. When something falls between two of them it is still inside ours, so it is our problem to solve rather than yours to arbitrate.

The interfaces are priced

We tell you at tender what we are excluding and where we think the risk sits, rather than discovering it as a variation. An exclusion you know about before award is a decision. One you find afterwards is a dispute.

Built for sites that cannot stop

Data halls, rail stations, defence sites, live wards and trading branches. Staged delivery, work in occupied buildings, night and weekend windows, and inductions taken seriously because the site rules are not negotiable.

Evidence, not assurances

Per-link test results, witnessed testing, labelling schedules, as-built drawings and a reconciled asset register. Procurement-grade documentation, issued at handover rather than promised during it.

What you can check

Claims on a website are worth what you paid for them. These are the ones you can verify independently before you shortlist us.

Impac Prequal 5-Star

Category 1 prequalified. Verifiable through Impac rather than through us.

Site Safe certified

Current Site Safe certification, and inductions completed before crews are on your site.

When you do not need us

A specialist is not always the right answer, and pretending otherwise would undermine the rest of this page.

  • A single trade, cleanly bounded. Twenty outlets in a tenancy with no security, no commissioning and no live environment. Give it to a good cabling contractor and pay less than we would charge.
  • You already have the coordination. If you have a competent ICT project manager who owns the interfaces and has the authority to direct trades, you have already bought the thing we are selling.
  • Lowest price genuinely is the brief. If the environment can tolerate rework and delay, the economics favour trade packages. We would rather tell you that than win the job and disappoint you.

Where it does matter is where downtime is expensive, the site stays live, the documentation gets audited, or the programme has no float. That is the work we are built for.
