What is leased line broadband? Do you need a leased line?

In this guide

A leased line is a dedicated broadband link primarily aimed at businesses which ensures that bandwidth remains fixed. 

If you have broadband at home using an Openreach telephone line then you may notice internet speed dropping at peak times, as everyone shares the line and the local bandwidth is maxed out. The same will happen if you're in an area with a heavy Virgin Media fibre broadband presence. 

But with a dedicated leased line broadband connection, this problem is overcome. You pay a higher subscription for your own line to ensure your connection remains fast, unaffected by the activity of other local users.

However, leased lines are not cheap, starting at around £100 a month. This price point means leased lines are usually intended for business premises, rather than typical domestic use. 

Leased line availability in the UK

Almost all UK-based Internet Service Providers (ISPs) offer leased lines to businesses. These are typically available in a range of packages based on the expected usage. For example, a small business might only need the starter package with a relatively modest speed; conversely, an enterprise-level company will probably use the top end package with very high speeds, potentially spending a huge amount each month for extremely rapid connections.

As you can see, dedicated leased lines can be vital to business users, as well as educational, healthcare, and government buildings.

Leased line speeds

Leased lines are available in a variety of packages, usually based around the Ethernet Access Direct (EAD), Ethernet First Mile (EFM) and Ethernet over Fibre (EoFTTC) protocols.

These all offer Ethernet connectivity from a central router (or switch) on the premises, with the speed and price determined by the choice of package.

Leased lines do not necessarily have to offer ultrafast broadband. The important part of a leased line is that it is dedicated and uncontented, but not every business needs gigabit fibre. For example, BT business broadband offers leased lines with speeds from 10Mb up to an incredible 10Gb. 

Leased lines may be symmetrical, which means that the connection is the same speed for both download and upload. That can be a very important feature for businesses; a typical residential service will provide asymetrical speeds where uploading is much slower than downloading, and sending data can take a long time.

Set up for these packages is usually fast, with EAD potentially available the same day if the equipment is already installed. Note that Openreach also offers a service for handling large volumes of data, Ethernet Backhaul Direct (EBD), ideal for video streaming and maintaining continuity should the main fibre network fail.

Do I need a leased line?

By this stage if should be obvious whether you need a leased line broadband connection. These types of connections are intended for commercial usage, and while they can be installed in homes it would be entirely unnecessary. If nothing else, they don't make financial sense when there's a wide variety of cheap broadband deals available that are perfectly sufficient for typical domestic use.

Many businesses can also get by with the same types of services as home users, especially smaller businesses which don't have specialised requirements or a large number of employees. Conventional business broadband deals are affordable and fast enough for many tasks. However, as the requirements of your business grow, so will your demands. Sending emails all day is one thing; online collaboration, private servers, video calls, and online backup services used could demand the speed and reliability of a leased line.

Consider a leased line if:

  • Your business activities require a dedicated line
  • You have multiple users connected all day
  • You require a fast, resilient network connection

You don't need a leased line if:

  • You're just looking for home broadband
  • Your business is very small or run from home

How do I get a leased line?

The best way to get a leased line is to get in touch with your preferred ISP's business sales department. However, before you do this, take the time to do some research into customer service and installation times. You should also investigate what the fastest speed is available in your area.
