Common problems

What these projects usually need

The scopes we are asked for most, and how we run them

New fit-out

Empty floor that needs everything

Cabling, network, CCTV and Wi-Fi planned together before any drilling starts.

Old system upgrade

Ten-year-old cabling and cameras

We reuse what still works and phase the upgrade so you do not have to stop work.

Office move

Relocating with a deadline

Cutover planned outside your working hours, with the old site left tidy.

Dead spots and complaints

Wi-Fi or cameras not covering

Measured on site, then APs or cameras added where the survey says they are needed.

Cable chaos

Cabinet nobody can read

Re-terminated, labelled and documented, so faults take minutes instead of hours.

Compliance and safety

Insurer or landlord requirements

Cable routing, earthing and racking brought up to standard, with documents to prove it.

Growth

More people than the network can carry

Capacity planned for where you will be in two years, not just today.

Multi-site

Several locations to keep consistent

One standard applied across every site, with one contact for all of them.

How to judge us

Quote, schedule and warranty — up front

Every item listed with brand and quantity

The quote lists every cable, device and labour hour, so you can compare it properly.

Fixed price, no surprises

One price agreed before we start. Scope changes are quoted separately, never added later.

Schedule in the contract

Completion dates are written in, and we work outside your hours where that helps.

One-year workmanship warranty

Non-human faults inside 12 months are handled free of charge.

FAQ

Questions we get asked most

01

Can the project be run in English?

Yes. You get an English-speaking project lead, and scope, quote and handover documents can be issued in English.

02

Is the site survey free?

Yes. We survey, agree the scope and draw it up before quoting anything.

03

Do you use genuine branded materials?

Yes, and every quote lists brand, model and quantity so you can check.

04

Can you work outside our business hours?

Yes. Fit-outs, moves and cutovers are often scheduled at night or at weekends.

05

Will the price change halfway through?

No. The price is fixed once the scope is agreed. Any change you ask for is quoted first.

06

What warranty do you give?

One year on workmanship. Non-human faults inside that period are handled free.
