What is a leased line?

Leased lines are a premium form of broadband. The term ‘leased’ is simply used to describe how the internet access is rented from the ISP (Internet service provider). Leased lines are also referred to as dedicated internet access. This is because of the ‘always on’ internet connectivity, 100% uptime guarantees and 24/7 support.

A dedicated line provides your business with its own fibre line between your premises and the local exchange. This means your business benefits from its own dedicated fibre access. The line is not shared with neighbouring homes and businesses. In comparison, standard business broadband is delivered through your local street cabinet via cables, which are shared with multiple properties.

With a dedicated line you won't need to struggle with slow connections at peak times. Your business will receive the fastest speeds available with no drop-in service.  In addition, the fixed bandwidth provides identical upload and download speeds. This is ideal for businesses which rely on being able to upload large files to the cloud.

Is your businesses increasingly relying on cloud services and internet access? Is your current internet service not fast enough or reliable enough. Then a dedicated leased line could be the answer. Read through our list of the top 10 leased line providers and see if you can find the right solution.


The benefits of choosing BusinessComparison for your leased line comparison

For many businesses which rely on the internet to operate, service uptime is one of the most important factors. For example, does your business relies on access to VoIP, cloud computing and VPN services? If so, then slow and unreliable internet access will cause many difficulties. Leased line providers offer a Service Level Agreement (SLA), which guarantees a certain uptime level. If the service does drop, you will receive credit for each hour your business is without broadband.

There are large providers which you are likely to be familiar with. These include house hold names like BT, Virgin Media, and TalkTalk.  In reality many providers use each other’s networks to supply connections. This means that many will offer similar speeds. The main differences between suppliers will be the cost of the leased line and the customer service levels.

1. BT


At the top spot in our list of the top 10 leased line providers is BT (British Telecom).  BT are the largest provider of leased lines in the UK. However, it is important to note the company also sells its leased line network to other suppliers at wholesale prices. Before 2001, BT was the only provider of dedicated lines. Today, however, your business could use the BT network, without using BT as your end fibre leased line supplier.

BT allows businesses to choose their own line speed. This is useful as you will be able to create a bespoke package which is tailored to your business’ requirements. For example, does your business rely on bandwidth hungry activity such as VoIP calling or cloud uploads. If so, a faster bandwidth speed may be the most suitable option.

  • Top speed available with BTnet Express is 30Mbps, with BTnet offering up to 10Gbps.
  • Bespoke packages available.
  • Options available for small businesses.
  • Symmetrical download and upload speeds.
  • Simple pricing structure.
  • 100% target service availability.
  • 24/7 customer service.
  • Issues are resolved quickly.

TalkTalk was created following the merger of several smaller internet service providers. These were AOL, Tiscali, and Opal and the mobile phone retailer Carphone Warehouse.

There are a variety of ethernet leased line options to choose from. These include Ethernet Access Direct, Ethernet First Mile and Ethernet over Fibre.

The leased line product is Extreme Internet Access. This offers flexible internet speeds of between 100Mbps up to a maximum of 10Gbps. This is why SSE features in our list of the top 10 leased line providers.

4. Vodafone Business


In 2012 Vodafone purchased the UK arm of Cable & Wireless. This was the first leased line supplier to offer an alternative to the BT service. Cable & Wireless was the result of a merger between several smaller dedicated line providers. These included Energis, Thus and Local Loop Unbundler Bulldog.

The Vodafone leased line service connects customers directly to the Vodafone IP backbone. This in turn is helping to expand the Local Area Network both nationally and internationally.

Virgin Media does not cover as much of the UK as BT. However, they do have widespread coverage and competitive pricing. The provider offers dedicated fibre Ethernet connections with symmetrical download and upload speeds.

6. Colt


Colt stands for City of London Telecommunications. They began by providing leased lines to key financial districts, such as the London Docklands, central Manchester, and central Birmingham.

It provides services to large multinationals and large public sector organisations.

You are likely to find that the price offered for a Colt leased line is hard to beat. But only if you are located within an area serviced by Colt.  As such, Colt does not quite reach the top of our list. If you do happen to be in a Colt area, we recommend including them within your leased line comparison.

As such, not every business will be able to access a CityFibre leased line.

  • Speeds of between 2Mbps and 10Gbps available.
  • A scalable service with bandwidths that can be easily increased.
