Business broadband availability in 2025

Choosing the right business broadband starts with knowing what’s available at your location. Our experts have analysed the latest coverage data from the UK’s major broadband providers to help you find the best connection for your business.

We focus on the broadband options that matter, excluding regional-only providers like KCOM and outdated technologies like ADSL broadband and GFast, which are no longer available to new customers.

We’ve created this guide to help you make the right choice. Let’s start by exploring the different types of broadband available to British businesses.

Openreach full fibre availability

Openreach has ambitious plans to deliver full fibre broadband to 25 million properties by 2026.

Availability: Approximately 50% of all British properties.
Providers: Around 30 providers, including BT Business Broadband, TalkTalk Business Broadband, and Sky Business Broadband.
Progress: Expanding rapidly.

Openreach full fibre offers speeds of up to 1 Gbps. Find out more in our guide to full fibre business broadband.

CityFibre full fibre availability

The CityFibre network boasts the fastest full fibre service, with symmetrical speeds of up to 2.5 Gbps.

Availability: Currently available to 4 million premises in Britain’s largest cities.
Providers: 20+ business broadband providers, including Vodafone Business Broadband.

Dedicated leased line availability

All of the above full fibre and cable networks can also provide dedicated leased line business broadband. Leased line broadband offers unrivalled speeds of up to 10 Gbps.

Availability: Available in most areas except remote locations, although the cost of a leased line installation is significantly higher in rural areas.
Providers: Many options are available, see our guide on leased line broadband providers.

Openreach SoGEA availability

A part-fibre, part-copper connection with widespread availability in Britain, offering maximum speeds of up to 80 Mbps.

Availability: Available to over 95% of commercial properties in Britain.
Providers: 20+ business broadband providers.
Progress: No new rollout, as it is being replaced by faster full fibre technology.

For a full explanation, visit our guide to SoGEA business broadband.

Mobile broadband availability

Mobile business broadband is delivered through 5G and 4G cellular networks.

Availability: Available to 75% of commercial properties.
Providers: The four major cellular carriers are O2, Three, EE, and Vodafone.
Progress: Coverage and speed upgrades are ongoing across all carriers.

5G business broadband is the only high-performance mobile broadband option, with availability limited to towns and cities.

Satellite broadband availability

Satellite business broadband can be set up anywhere in Britain, although it suffers from slow speeds and high latency.

Availability: Universal coverage in Britain and surrounding seas.
Providers: Starlink, OneWeb, and others.

The performance of satellite broadband technology is improving as the number of low-orbit satellites increases.

How to check business broadband availability

Business broadband availability varies with location, with each broadband network focussing on expanding into different areas.

Checking which broadband networks are available at your address is the first step in finding the right broadband deal. We outline two best ways to do this below:

Ofcom’s availability checker

The broadband regulator Ofcom provides a broadband coverage checker on its website. By entering your postcode, the service displays the network providers and speeds available.

Unfortunately, there are a few key limitations to this service:

It acknowledges that it does not have data from all networks.
Where multiple network providers are available, it does not indicate which is the fastest
It does not help you compare the prices of different options.
It does not analyse leased line connection options for businesses.

The alternative is to speak with our business broadband experts about the best options in your area.

Talk to our broadband experts

Our business broadband experts are on hand to help you assess the different business broadband options available at your location.

What are the most important factors of business broadband availability

When evaluating broadband availability, it is important to consider several key metrics:

Coverage

Coverage is the most fundamental factor for broadband availability. It determines what broadband service is available and is influenced by the infrastructure in place, such as fibre, coaxial cables, or 5G networks.

Speed

Speed indicates how quickly data is sent and received over the connection. It is typically measured in megabits per second (Mbps) and affects everything from browsing to streaming and downloading.

Bandwidth

Bandwidth refers to the capacity of the connection in Mbps, determining how much data can be transmitted at once. Higher-bandwidth connections can be upgraded as your business grows and requires faster internet. Find out more in our guide to business broadband scalability.

Contention

Most broadband services use shared infrastructure with other nearby businesses. When multiple businesses in the same area use the same network, it can impact performance. Find out more in our guide to business broadband contention.

Reliability

Reliability refers to the consistency of the broadband service, including uptime, latency, and disruption frequency. Tethered broadband services are generally more reliable. Find out more in our guide to business broadband reliability.

What if your business broadband availability is poor?

Some regions in the UK have extremely limited broadband availability. This is a pressing problem with the upcoming PSTN switch-off and the transition to digital business phone lines.

Here, we explore options for securing reliable high-speed internet in areas of limited business broadband availability.

Gigabit Broadband Voucher Scheme

The Gigabit Broadband Voucher Scheme (GBVS) is a government grant programme designed to incentivise broadband providers to extend their full fibre networks to even the most remote communities.

The scheme provides up to £4,500 per new business connection. Find out more in our complete guide to the Gigabit Broadband Voucher Scheme.

Wireless leased line solutions

A wireless leased line is a broadband solution that uses two antennas pointing at each other to provide dedicated high-performance internet over long distances.

Find out more about wireless leased line solutions on our dedicated page.

Network load balancing

Network load balancing is a cost-effective way to boost bandwidth and reduce downtime for existing older business broadband connections.

Network load balancing combines the performance of multiple connection types into one high-performance solution.

What influences business broadband availability

The main factor affecting business broadband availability is how far network providers have expanded their infrastructure.

Broadband providers operate as commercial businesses, meaning they focus on expanding their networks to where they are financially viable. They invest in areas with high demand, ensuring a return on their investment. In contrast, regions with fewer potential customers, particularly rural areas, often face limited broadband options due to the high cost of expansion.

Geography also plays a role. Natural barriers like hills, mountains, and bodies of water can make extending fibre optic networks to certain locations even more expensive.
