What is a Leased Line?

A Fibre Leased Line, or Fibre Ethernet Circuit, is a dedicated data connection providing uncontended broadband internet access for your business.

It provides:

  • access to the Internet
  • a connection for phone calls (including VoIP)
  • linking between PCs and servers across multiple offices in the data network
  • off-site/remote working for staff
  • symmetric speeds; fast uploads and downloads of large files

It’s purpose is also to connect two locations together and can therefore work across company sites. There is normally a primary location, the main corporate office, which is then connected to another office that is part of the same business.

Benefits to your business

There are several advantages to choosing a Fibre Leased Line service over more traditional copper based broadband services, such as FTTC and ADSL Broadband.

Reduced Costs

Switching to a Fibre Leased Line helps reduce the cost of private networking, while improving the quality of service and support your business receives.

Prioritised bandwidth

For consistently high speeds, there are two bearer options that we typically quote- 100MB bearer and a 1GB bearer, with various bandwidth options available in between depending on your business requirements.

Scalability and flexibility

Legacy communication services, such as ISDN, aren’t flexible enough to provide the same high quality connection as a business expands. Leased Lines have a bandwidth that can be easily increased to cater to new and more users, and can be decreased should the need arise.

Uncontended service

You benefit from direct access from the exchange to your business premises, ensuring you get the speeds and services as stated in your agreement. Should you outgrow your line, it can be upgraded and grow with your evolving needs.

Unlimited usage

With a Leased Line you and your business can use as much data as you require to complete your tasks. You don’t need to worry about reaching a ‘maximum usage’ and being charged extra, or reaching a point where all of your data has been used.


A fibre connection is known to be more reliable than the ageing copper network that has been used for so long. One of our experts can discuss the benefits of a Leased Line to your specific set-up and requirements. Don’t hesitate to get in touch.

Fast speeds

As an uncontended ‘unshared’ service, your business will receive incredible speeds across a range of tasks and applications. These speeds have no fluctuations throughout the day so productivity doesn’t suffer because of a struggling bandwidth. Not happy with your current connectivity? Check your speeds using our broadband speed test checker.

Resilience and security

This is very important for critical business applications and the use of cloud based services. Communications and data on your line will be resilient even when multiple applications are being used – voice calls, video conferencing – and will also be protected by a firewall. The level of security makes it an ideal choice for companies dealing with sensitive and private data, such as those in the medical, education or financial industries.

What does uncontended actually mean?

Uncontended broadband is delivered via a Fibre Leased Line and means that only your organisation or business has access to the connection – you don’t share it with any nearby users or other companies.

It ensures fast speeds and direct access to the Internet without other outside or third party businesses slowing it down. Developed for businesses, they are private, secure and dedicated purely to you.

The uncontended service and guaranteed up and down symmetrical speeds mean that you can begin to add additional services to the connection such as CRM access and collaborative communication services such as VoIP Telephony and Unified Communications.

Many more business applications are becoming cloud-based including Accounting software such as Xero and Quickbooks. A leased line is generally the best internet service a business can opt for to ensure that all these services can run over the same dedicated connection.

In comparison, uncontended internet connections include ADSL, FTTC and FTTP. These will all experience peak times with upload and download speeds fluctuating throughout the day. This isn’t ideal when you have multiple users on a conference call for example, or see an influx of calls to your business after a successful marketing campaign.
