Leased Line Broadband

A leased line is a dedicated and private broadband connection.
Leased lines provide the fastest data connectivity available in the UK.


What is a leased line?

Leased lines are ‘dedicated’. This means instead of sharing a broadband line with your neighbor, you rent a single dedicated line on a private circuit. On shared PTSN connections like ADSL or FTTC, at peak times internet connectivity is greatly hampered. (find out more about fibre broadband) A leased line only carries your data and you achieve consistent speeds no matter the time of day or location. There is no break in the fibre connection.

Leased lines are used for the internet, but also to connect two locations e.g. data centres or connecting offices. This is why they are also known as ethernet leased line, dedicated line, data circuit or private line.

A symmetric connection means you can send data just as fast as you can receive it. Businesses with high data-connectivity need a 1:1 connection ratio for data centres, cloud backup services and when using online software.

Businesses that use SIP Trunking benefit greatly from this type of connection. 2Mb leased line has enough bandwidth to support 48 concurrent calls. Compared to an 8Mb ADSL connection that can support up to 12 calls. This is due to the uncontended, symmetric bandwidth of leased lines. The most common connections available in the UK are 100Mb/s to 1Gbit/s (gigabit). In larger cities speeds of 10Gbit/s are possible.

Leased Line FAQ’s

The average time is 60 days. It can be a complex process, so we manage it and work with our suppliers on your behalf. In some circumstances, if a customer needs a shorter lead time we can supply 4G or 5G solutions. This can be useful where, for example, there is an urgent office move.

The key difference between FTTP and Leased Lines is how they are connected. FTTP (fibre to the premises) services are shared with other internet users therefore speed is compromised at peak times. Lease line is solely for your business. FTTP is also asymmetric with larger download speeds compared to upload. Leased lines deliver symmetrical speeds of 99.9%
