Each routes to the page that answers your questions first.

I run a data centre — or I’m building one.

New-build connectivity is what we do most weeks. Diverse routes, 100Gbps and 400Gbps to the front door, multiple carriers in the mix.

See how we help

I run an ISP or an IT business.

Two buildings, eleven cities, contract renewal in six months. We’ve done all of those — Ask4 picked us for eleven of them.

I’m building AI infrastructure.

Funded, on the clock, and you need to show your investors the network is real before the tenants arrive. We’ve done the 15-site evaluation. We can do it again.

How a fibre order goes wrong

Getting fibre installed usually goes badly.

Slow quotes, charges nobody mentioned, late installs, and backup lines that aren’t really separate. Here’s how it normally plays out.

01 / WEEK 1

The quote takes six weeks

You ask for a price. Six weeks later it arrives — and the numbers are wrong.

02 / WEEK 7

Hidden charges appear

Extra construction costs nobody mentioned suddenly land on the bill.

85% of quotes hide these charges — £1,000 to £10,000 per site.
03 / WEEK 8

The wait drags on

Sixteen weeks before the line is live.

The published industry average is 60–120 working days.
04 / WEEK 24

The backup line isn’t separate

You paid for two independent routes so one fault can’t take you offline. They turn out to run through the same trench — so a single digger cuts both at once.

What Sicom does instead

The same job, done properly.

We’ve heard the four problems above every week for years. Here’s how we handle each one.

01 / A quote that’s right

A real price, fast

We pick the right carriers for your route — sometimes Openreach, sometimes Colt, often a combination.

Same week to a budgetary quote. Surveyor on site within a week.
02 / No surprises

Every cost in writing

We tell you the costs, the extra construction charges and the wayleaves up front — before you sign anything.

Charges in writing before signature. If we’re wrong, we wear it.
03 / Built by us

We do the build

Then we build it — civils, fibre, the lot — so the timeline is ours to keep, not someone else’s to slip.

04 / Watched for life

Monitored by RADAR™

Then we monitor it from RADAR™ for as long as you want us to — we see a fault before you do.

Featured case study — Ask4, West London

Eleven buildings. Multi-core dark fibre. Ownership kept with Ask4.

Eleven luxurious residential buildings across West London, plus the Management Suite. Legacy copper out. Multi-core dark fibre in. Ownership of the network kept with Ask4, not the carrier.

The same approach now runs across eleven UK cities — York, Bath, Southampton, Glasgow, Aberdeen, Lancaster, Falmouth, Sheffield, Nottingham, Cardiff and Birmingham. RADAR watches the fibre. We pick up the phone before they ring.

“The use of multi-core dark fibre cables allows us to benefit from instant scalability. Ownership of the fibre fixes the costs and provides a saving or 50% or more over the projected life of the contract.” — Ask4, West London Residences

RADAR™

Our fibres watch themselves.

RADAR (Remote Automated Detection and Reporting) is our own product. It sits in your comms room, checks the condition of every fibre in your network every few seconds, and compares the readings to a fingerprint we took at installation. When something changes — a bend, a trapped lead, a break — we know. And because RADAR is linked to a GIS-mapped picture of the route, we know where on the map the fault is. Often before you’ve noticed. Built in-house. On live networks today. Free for clients on long-term support agreements.

How RADAR works
RADAR™ sees this

What a live fibre looks like.

Light pulses through dark fibre at the bandwidth you choose. RADAR™ watches at 1650nm — outside the wavelengths the data is using — so it sees attenuation events the moment they happen. A bend. A trapped lead. A break. Before the network notices.

Why people choose dark fibre

The four pillars.

The four reasons our clients end up owning the fibre they paid for, instead of renting it back from the company that installed it.

It’s your fibre, lit at the bandwidth you want, not the bandwidth a carrier’s product catalogue allows.
The dark fibre asset has a long life. The leased-line bill compounds for the length of the contract. The maths usually favours ownership past five years — sometimes sooner.
Want to move from 10Gbps to 100Gbps? Change the equipment, not the contract.
Few competitors do business this way. It does need explaining — that’s part of the job.
Second case study — Focus Sensors / Dark Fibre 2

£1.49m OFWAT-funded. Dark fibre as a sensor.

A £1.49m project funded by the OFWAT Water Breakthrough Challenge. Severn Trent, Welsh Water, and Northumbrian Water are the partners. Focus Sensors’ IndusTM system turns ordinary telecoms fibre into a sensor that can locate water leaks along the route. Our role is to provide the dark fibre in five test areas.

The wider goal — what OFWAT is funding — is a billion-litre-per-day reduction in UK water leakage by 2030. Dark fibre, the same passive cable that carries data, is doing the sensing.
