If you can't afford to lose your internet connection, you need a leased line.

If you want a dedicated internet access service beyond business broadband, with guaranteed upload and download speeds, take a look at a BTnet Leased Line. It’s like having your very own pipe, capable of carrying enormous amounts of data.

As you don’t share the bandwidth with anyone else, you get complete control over it: flex your bandwidth in line with seasonal demands and only pay for what you need.

With symmetric speed choices ranging from 2Mbps to 30Mbps (Ethernet First Mile - EFM), 35Mbps (Generic Ethernet Access – GEA), and 10Gbps (Ethernet fibre), plus resilience options, a leased line is ideal for businesses where internet access is critical.

And ultra-low latency makes it the natural choice for financial trading applications and top-quality video conferencing.

Watch the video to find out why a leased line is the ultimate internet connection.

This allows you to plan the performance of your applications with full confidence.

Guaranteed symmetric download and upload speeds

Symmetric means your download and upload speeds are the same. Essential for uploading to the cloud, web hosting, streaming, sharing large data files and using VoIP.

The bandwidth depends on which Leased Line you opt for -

Ethernet First Mile Access BTnet Leased Line
2Mbps to 30 Mbps

2Mbps to 10Gbps

Ability to flex your bandwidth up and down

Change your bandwidth to suit your seasonal business demands and control your costs by only paying for the bandwidth you need.  

You can flex bandwidth within the capacity of your bearer circuit (this is the maximum bandwidth that you’ll ever need that we agree when you buy your leased line) with only 72 hours notice.

Your rental charge will change on a pro rata basis for the period of flex, so you can pay less in quieter periods.

Unlimited usage

There is no fair usage policy; you can use as much data as you like.

Optional extras

Resilience: Failover, Backup and Load Balancing

Protect your business against problems beyond our reasonable control such as flood, fire, criminal damage.

Although we have a 100% availability target backed up by an SLA, there are times when that isn't enough to keep your business working.

There are three resilience options available with a BTnet Ethernet Fibre Leased Line

Failover, Backup, and Load Balancing.


If anything goes wrong, everything continues to work as normal.

  • We manage a secondary leased line for you that we only activate if there's a problem on your main line
  • The secondary line is identical in size and performance to the primary line
  • Traffic is only restored to the primary link once it's available
  • We set up and manage the failover as part of our managed service


A cheaper option than Failover because it uses a smaller size and bandwidth than the primary line.

  • We manage a secondary leased line for you that we only activate if there's a problem on your main line
  • The secondary line has a smaller size and bandwidth than the primary line
  • You have emergency backup for your applications but at a reduced performance level to that of the primary line

Load Balancing

Load balancing is a more complex resilience option.

  • You manage a secondary leased line that remains fully active during normal operation, working alongside your primary leased line
  • Traffic can be load-balanced across both links (it is not load-shared)
  • In the event of failure on either of the lines, all traffic routes to the active line

BTnet Quick Connect

Installing BTnet can sometimes take a while. But with BTnet Quick Connect you don’t have to wait too long to get fast internet access with in-built resilience.

Take BTnet Quick Connect and we’ll install a low-cost back-up circuit using EFM (Ethernet in the First Mile) in advance of your main service.  You can then use this service while we work on installing your main Ethernet Fibre access. Once we’ve installed the main circuit, BTnet Quick Connect takes over as a low-cost, resilient back-up service.

BTnet Quick Connect is only available with Ethernet Fibre access and EFM/GEA back-up.

SIP trunking with BT SIP Trunk

SIP trunking can help you save money by using your data network to handle all your calls so you no longer need separate phone lines.

BT SIP Trunk channels start at just £8.95 a month, which includes a generous call allowance and free calls between BT SIP Trunks.

Quality is just as important, which is why we offer Quality of Service that ensures calls are prioritised, so quality is not compromised.

You also get more flexibility than with traditional phone lines: you can market your business locally around the country, take your numbers with you if you move, and have your calls diverted to another site in the event of an emergency.

If you’re investing in a data network, SIP trunking makes that investment work harder for you. BT SIP Trunk.
