What is a Leased Line?

Leased lines are a direct line between your business and the world-wide-web, offering outstanding performance for both voice and data connectivity. Because they offer high bandwidth and fast upload and download speeds at all times, they are the ideal way to link your office to the internet without contention with other businesses. Unlike a standard internet connection where download speeds heavily outweigh upload speeds, this connection is symmetrical and the data travels at equal speeds in both directions.

A fibre optic leased line is a dedicated connection delivered directly to your business premises from the local exchange, providing robust and guaranteed high-speed performance, irrespective of the line’s length. It is the ideal option for businesses that regard high-speed internet access as mission-critical across both voice and data.

Simply put, a leased line is a dedicated, fixed-bandwidth, symmetric data connection. It is the fastest, most secure and most reliable data connection option available on the market today for internet critical businesses. Why not contact Juno Telecoms, as the top UK leased line providers, to explore the leased line cost options available to you?

What Can Leased Lines Be Used For?

Just like a pipe that can carry many things, a leased line can be used to carry a variety of data traffic, such as internet traffic to include web pages, emails, video streaming; VPN (Virtual Private Network) traffic over WAN or LAN; phone calls; and VoIP (Voice over Internet Protocol).

When choosing a leased line, there’s no need to pay for more than you need at the time. A DIA is capped by what’s known as a committed data rate (CDR) and the bearer capacity. The bearer indicates the upper limit on your speed, and the committed data rate can be tailored to match your current bandwidth needs. 

You might only need 100Mbps (CDR) currently, but have 1000Mbps as a bearer, so you would order a 100/1000 circuit with the capability at a later date to upgrade to higher CDRs up to a maximum of 1000Mbps in this example. 

This will impact the initial leased line cost. Bearers can be 100Mb, 1Gb or 10Gb. Leased Lines are symmetrical, which means that if a 100MB leased line is requested, on a 1Gb bearer, businesses will have 100MB upload and download speeds.

When your business grows, upgrading is simple, leaving you in charge of the leased line price as you grow. You request a regrade to a higher CDR with your leased line providers. You won’t be left with an expensive bill for new and improved infrastructure, because a leased line is flexible enough to grow with you.

They can be used to:

  • Link corporate offices to the internet and collaborate online
  • Connect local area networks, or several corporate offices together
  • Link PCs and servers in different locations
  • Carry phone calls and adopt Cloud Telephony
  • Share IT resources and carry large amounts of data between sites
  • Enable remote connections to head office PC

Are Leased Lines Right for Me?

To gauge, whether your business would benefit from the installation of a leased line, consider the following questions:

  • Is your business internet critical?
  • Do you need to connect geographically distant offices?
  • Do you need your workforce to connect to their work computer from remote locations?
  • Does your business rely on sending and uploading large files?
  • Do you rely on seamless conference calls?
  • Do you require simultaneous collaborative work in the cloud?
  • Do you make use of VoIP telephony?

If running your business successfully requires constant internet activity for communication and transmission over the internet, then future proofing your business by investing into a leased line is probably the right choice for you. The positives will always outweigh the negatives.

Advantages of Leased Lines UK

There are a number of benefits when it comes to installing leased lines in your company, these benefits include;

  • For businesses who operate in multiple locations with remote staff, and those who rely on the quick transfer of large data between users, a dedicated line will have a direct, positive impact on both workforce productivity and overall client experience.
    With leased lines, data transfer is uncontended, therefore there is no ‘slow-down’ at peak times. The performance of the connection is not affected by other users on the network or the exchange.
  • Leased lines are usually more reliable than more traditional ADSL connections. Unlike an ADSL connection (Asymmetric Digital Subscriber Line), which is a broadband connection utilizing existing phone line copper wires, leased lines use fibre optic cables, which do not suffer the same electrical interferences, and they also come with higher grade hardware for durability.
  • Having a leased line means that there is business class support at hand 24/7. Leased lines come with Service Level Agreements (SLAs), and Service Level Guarantees (SLGs), which guarantee a quick fix time where major connectivity issues will be resolved quickly and efficiently.
  • Leased lines are a good investment for growing businesses. With the range of products and services currently available on the market, leased lines offer a flexible solution for business expansion. Leased lines can be tailored to meet changing business needs over time, without the need to uproot the existing infrastructure.
  • Although dedicated lines are more costly to install, and the leased line cost is affected by a number of factors, this can be tailored to individual business budgets and the business requirements, with future expansion in mind. Leased line prices on contracts of 3 years or more, usually include the costs of the initial installation and router equipment costs.

Some other benefits of business leased lines include;


DSL broadband is unreliable for businesses relying on the internet for daily operations. A leased line provides a dedicated and uncontested connection ensuring reliable performance levels 24/7. No more worrying about FUP or internet drops. Focus on using as much data as needed for a fixed monthly price, meet deadlines, communicate with the workforce, and close those deals confidently.

Better Support

If your broadband connection goes down, you could be without an internet connection for days. This could have disastrous consequences for your business. Therefore, a leased line comes with a Service Level Agreement (SLA), which guarantees that major connectivity issues will be resolved quickly and efficiently. The providers’ Network Operations Centre monitors their connections around the clock, ensuring that help is on hand if a line goes down.

Faster Upload Speeds and Download Speeds

A dedicated line offers synchronous bandwidth speeds of 10 Mbps to 10 Gbps. You control the bandwidth distribution, making it ideal for large file transfers, cloud uploading, in-house server hosting, streaming, VoIP telephony, video conferencing, and data file sharing. Leased Lines offer no data transfer limit and ultra-low packet latency, perfect for high-end applications like HD video and Voice over IP. Redundancy and resilience options are also available for further peace of mind.


A leased-line is also referred to as dedicated internet access (DIA) line because it is exclusively dedicated to only the two locations it is connecting. Combined with appropriate router and firewall settings, a dedicated internet access line, reduces the security risks due to it not being a shared service as with DSL circuits.

Leased Line Quotes

There is no escaping the fact that leased lines are more costly than more traditional Asymmetric Digital Subscriber (ADSL) or Fibre to the Cabinet (FTTC) connections. Get in touch with Juno Telecoms for leased line prices on services available to you. Whilst it is true that using standard internet can be much less reliable and secure if your business is not internet critical, then the likelihood is that a standard, market-ready DSL (Digital Subscriber Line) broadband connections will do the job for you at a fraction of the price. 

Leased line costs have reduced greatly over the last two years, so they offer genuine alternatives for business broadband. Our Ethernet leased lines are available in three different products, namely Fibre Ethernet, EFM and EoFTTC. Fibre Ethernet is available from 1Mbps up to 1Gbps internet speeds, EFM speeds are from 1Mbps to 35Mbps, and EoFTTC speeds vary from 1Mbps to 20Mbps.

However, if your business needs a highly reliable, but cost-effective connection backed by an SLA (Service Level Agreement), and you operate in multiple locations with remote staff where quick and efficient data transfer is critical, then investing in a leased line is probably the most cost-effective choice you can make for your business in the long run. Give Juno a call and we can review and do the comparisons for you across different leased line quotes to help in making the right business decision.

How Much Does a Leased Line Cost UK?

When it comes to leased lines cost it is completely dependent on a number of factors which include:

  • The addresses that are being connected
  • The amount of bandwidth required
  • The length of the contract you are willing to sign

The main factor in the cost of your leased line is determined by your location, as it can be difficult to connect to any pre-existing telecom networks, this will reflect in your line cost. The amount of bandwidth you need determines whether you’ll need to use a fibre-connection, or whether you may be able to get away with uncontended DSL circuits that are available at about 20% of telephone exchanges, and that are sometimes cheaper. The final factor in determining your cost is the length of the contract, as leased line circuits usually cost thousands to install.
