What to Know About Broadband in Belfast

Most homes and businesses in Belfast now have access to full fibre broadband. The Belfast Chamber announced in May that recent Openreach reports show coverage across Northern Ireland has reached 90% of properties.

Residents can usually choose between providers such as BT, Virgin Media, Sky, and smaller networks. Many services offer download speeds of up to 1000 Mbps using fibre to the premises or upgraded cable networks.

Government programmes have helped improve coverage in areas that were harder to reach. Project Stratum has connected over 81000 properties and Project Gigabit is planning further upgrades across the region.

Availability still depends on your postcode so the best way to check is by using our comparison tool to see what is available at your address

How To Choose The Best Broadband Deal In Belfast

Best on a Budget

Don’t overpay for reliable internet. Compare prices across all speed tiers, sometimes faster packages cost less due to promotions. Look for student discounts or social tariffs if eligible.

Don't Assume Faster Costs More

Faster speeds don’t always mean higher prices. Providers often discount higher speed packages to win customers. Compare actual monthly costs rather than assuming slower speeds save money.

Location Matters

Rural areas have different options than city centres. Use our postcode checker to see what’s actually available at your Belfast address and compare real speeds in your area.

Watch Hidden Costs

Setup fees, router charges, and mid contract price rises add hundreds to your bill. We show all costs upfront so you know exactly what you’ll pay.

Switch & Plant Trees

Every switch through Switchity plants a tree at no extra cost. Save money, get better broadband, help the environment.

In Contract? Calculate Before You Switch

Check your early termination fee first – some new providers will pay it for you. Or try haggling with your current provider’s retention team. Use our ETF calculator to see if switching saves money overall.

Types of Broadband Available in Belfast

A simple breakdown of the broadband connection types you might find at your address

Full Fibre FTTP

Fibre optic lines run directly to the property, with no copper involved. This is the fastest and most reliable type of broadband available.

Around 90% of homes and businesses in Northern Ireland now have access to full fibre, including many across Belfast. Download speeds can reach up to 1,000 Mbps depending on the provider.

Fibre to the Cabinet (FTTC)

A mix of fibre and copper, this type uses fibre to the street cabinet and copper for the final connection to your home.

It offers better performance than standard broadband but slower speeds than full fibre. Still widely used in Belfast, with performance depending on how far your home is from the cabinet.

Cable Broadband

This type uses a combination of fibre and coaxial cable, mainly delivered by providers like Virgin Media.

It can support high speeds and is available in certain parts of Belfast. Ideal for users who need fast connections but don’t yet have access to full fibre.

ADSL

Delivered over copper telephone lines, ADSL is the most basic broadband type.

It’s slower than fibre or cable, but still available in most areas. Best suited for light internet use, especially where newer technologies haven’t yet rolled out.

4G and 5G Home Broadband

Instead of using a fixed line, this broadband connects via mobile networks.

It’s a flexible choice for people without wired connections or those in temporary setups. Speeds vary depending on signal strength, but Belfast’s mobile coverage makes it a viable option in many areas.

CityFibre’s Role in Belfast’s Full Fibre Future

What to know about CityFibre’s full fibre rollout and availability

CityFibre is one of the major builders of full fibre infrastructure in the UK. It supplies wholesale fibre networks to ISPs rather than selling directly to consumers.

They offer symmetric full fibre services, meaning upload and download speeds match packages reaching 2.5 Gbps and beyond.

Their modern networks are up to 25 times faster than standard broadband and use less energy, making them both high-performance and more efficient.

CityFibre also participates in the government’s Project Gigabit initiative, helping extend full‑fibre access to harder to reach areas.

If you see CityFibre listed as an option in your area, it means you’re likely being offered a very future proof broadband infrastructure that can support growing data needs without frequent upgrades.

Trusted Providers on the CityFibre Network

Understanding which providers use CityFibre and what they offer

CityFibre partners with a range of established internet service providers (ISPs) to deliver full fibre broadband. ISPs such as Vodafone, Zen Internet, TalkTalk, and others use CityFibre’s infrastructure to offer packages in areas where the network is live.

These ISPs may offer plans that include just broadband, or combined services that bundle phone lines and other features. What’s available will depend on which providers are active in your specific area.

Because CityFibre does not yet cover every postcode, it’s important to enter your address into our postcode checker to see which ISPs and deals you can access locally.

Altnet Broadband in Belfast

What to know about smaller broadband providers offering full fibre in Belfast

Alternative broadband providers are becoming more common in Belfast. These companies often build and manage their own networks, separate from the larger brands, and offer full fibre connections directly to homes.

They’re known for fast speeds, stable pricing, and a more personal approach to customer service. In many cases, they also receive better reviews than the bigger names.

Most altnets offer full fibre broadband only, which can be more reliable than connections that still use older copper cables. Some also avoid mid-contract price increases, giving you more predictable bills.

If one is available in your area, it’s worth comparing them alongside the bigger providers.
