Many broadband providers across the UK utilize the extensive infrastructure of the BT Openreach network to deliver internet services to their customers. While BT is a retail provider itself, its Openreach division operates as a wholesale network provider, enabling over 650 Internet Service Providers (ISPs) to offer broadband connections.
Understanding the BT Openreach Network
Openreach is a key part of the UK's digital infrastructure, operating as a distinct business within the BT Group. Its primary role is to build and maintain the local network infrastructure, including the copper and fibre optic cables that connect homes and businesses to the internet. This wholesale model allows various retail broadband providers to offer services without having to build their own nationwide networks.
Because Openreach provides the underlying physical connections, a vast number of providers, both large and small, rely on its network. This ensures widespread coverage and competition in the broadband market.
Key Providers Utilizing the BT Openreach Network
Over 650 Internet Service Providers (ISPs) currently use the BT Openreach network to deliver broadband services across the United Kingdom. These providers range from the largest, well-known brands to smaller, more niche companies. Some of the most prominent providers that utilize the Openreach infrastructure include:
| Provider | Network Type | Notes |
|---|---|---|
| BT | Openreach | As part of the BT Group, BT directly utilizes its own Openreach network for its retail broadband offerings. |
| Cuckoo | Openreach | Known for its straightforward pricing and focus on customer service, Cuckoo operates on the Openreach network. |
| EE | Openreach | Primarily known as a mobile network operator, EE also offers home broadband services leveraging the Openreach infrastructure. |
| NOW Broadband | Openreach | A subsidiary of Sky, NOW Broadband provides flexible and contract-free broadband options over the Openreach network. |
| Plusnet | Openreach | Another brand within the BT Group, Plusnet is a popular choice for budget-friendly broadband packages delivered via Openreach. |
| Sky | Openreach | One of the largest broadband providers in the UK, Sky extensively uses the Openreach network for its residential and business broadband services. |
| SSE | Openreach | While primarily an energy provider, SSE also offers broadband services, utilizing the Openreach network for its connections. |
| TalkTalk | Openreach & LLU* | TalkTalk utilizes the Openreach network for many of its services and also has significant investment in Local Loop Unbundling (LLU), meaning they have their own equipment in BT exchanges, connecting directly to the Openreach cables for certain areas. |
*Local Loop Unbundling (LLU) means a provider has their own equipment installed in Openreach's local exchanges, allowing them greater control over the services they provide over the 'last mile' of Openreach's physical network.
Why ISPs Choose Openreach
The primary reason why so many ISPs opt to use the Openreach network is its unparalleled reach across the UK. Building and maintaining a nationwide network is incredibly expensive and logistically challenging. By leveraging Openreach's existing infrastructure, providers can quickly and efficiently offer broadband services to a wide customer base without significant upfront investment in physical lines.
This wholesale model fosters a competitive market, giving consumers more choice of providers and packages, even if many of them are ultimately using the same underlying physical network.

How to Determine Your Provider's Network
Most broadband providers will openly state which network they use. If you're unsure, you can:
- Check their website: Look for sections on their network or technology.
- Contact customer support: They can confirm the underlying network infrastructure.
- Use online postcode checkers: Many comparison sites can tell you which networks are available at your address.
Understanding that many providers share the same physical infrastructure, like Openreach, helps in making informed decisions, as the main differences often lie in customer service, pricing, bundles, and router quality.
