Broadband in Belfast

What is actually built in Belfast

Openreach and Virgin Media both serve the city. Fibrus has built full fibre across a large share of Northern Ireland, including parts of Belfast, and sells its own retail service. A Fibrus advert is not a promise that your street is released, and an Openreach retailer cannot sell you Fibrus fibre.

A city name is not a coverage map. Openreach full fibre, cable and independent fibre networks do not share a footprint. In Belfast you should treat a postcode-level advert as a hint, then confirm the premises. Flats, new builds and offices above shops fail this test more often than houses.

The housing, not the headline speed

Terraces, flats and newer developments on the edge of the city need an address check. If a previous tenant left a fibre box, photograph it before you order a second install from a different network.

If the building has a wayleave, a communal intake or a single landlord-chosen network, the 'national' brands may not be orderable even when the street looks well served. Ask the managing agent which network is in the riser before you pay an exit fee to leave a provider that was the only one who could serve you.

How to compare without fooling yourself

Rank the first year, not the 'from' price. Add setup, router and any months that jump after an introductory discount. Check upload if you send video or run backups. Check whether a phone line is included, charged extra, or simply gone.

One Touch Switch still means the gaining provider runs the process where both sides support it. It does not mean every network in Northern Ireland is interchangeable.

• Use the address, including the flat number.
• Write down the contract end date and any early-termination figure before you start.
• Separate broadband from TV, mobile and insurance. One Touch Switch does not move a TV package by itself.
• Keep a copy of the order confirmation with the planned switch date.

Switching in practice

If both providers support One Touch Switch, you order with the new one and they send the match and switch messages. You do not need to phone the old provider to resign, and you should not cancel first — cancelling can leave a gap or an unexpected cease.

In Belfast the usual failure is a bad address match, not a slow fibre. If the match comes back for the wrong flat, stop and correct it before the engineer date. A wrong match is how people lose the old service early.

A practical order of work in Belfast

Start with the address as the council or the landlord writes it, including the flat or unit. Run that through a comparison before you read a borough-wide claim about Belfast. Note which wholesale network each deal sits on. Two retailers on Openreach are substitutes only if both can order the same premises. A cable deal and a full-fibre deal are not substitutes when only one network is in the building.

Then price the first year in pounds. Write the introductory months, the price after them, any setup or router fee, and the early-termination charge on the contract you already have. If the fee is larger than the saving, wait. In Belfast people often switch because a poster looked cheaper and then discover the install cannot happen for weeks, or that the old contract still has a charge.

Decide the date you can be in for an engineer, and the date you can tolerate being offline. They are different. Book the later of the two if your work depends on the line. Keep the old router until the new service is up. Returning it early does not speed One Touch Switch.

What a comparison on this site will and will not do

The plans you see are a labelled mock catalogue. The ranking and the first-year arithmetic are there so you can see how a headline price falls apart. They are not a live quote and not an instruction to buy. Availability still has to be confirmed by the provider at the Belfast address you typed.

We do not run One Touch Switch, we are not Ofcom, and we do not operate the TOTSCo hub that providers use to message each other. When both providers support the process, you order with the new one and they send the messages. You should not cancel the old service first. TV, mobile, and a care alarm are separate. Ask about each before you agree a switch date.

If the result looks thin, the usual reason is the premises, not a broken website. A flat above a shop, a new plot, or a block with a landlord-chosen network will show fewer brands than a house on a rebuilt street. Compare again with the flat number. If it is still thin, that is information: there may be little to switch to, and leaving early would be an expensive way to learn it.
