Unlike broadband, which works on a shared platform, a leased line gives you a single line all to yourself. That means there are no busy periods or dips in data service to worry about. It’s consistent, reliable connectivity for your business. All day, every day.
How do I get a quote?
Contact our BTnet team to get support with choosing your network speeds or to get a quote. To get started, we’ll need to know what you’ll be using the connection for, as well as your site address and postcode.
How does a leased line work with voice traffic?
BTnet is optimised for voice traffic, including our Cloud Voice and SIP services, thanks to our low latency network that ensures there’s no lag on voice calls. What’s more, we prioritise voice traffic to ensure high-quality calls every time.
How does a leased line work with cloud applications?
Enjoy a reliable, fast and consistent connection on your cloud applications including Microsoft, Apple, Google and Amazon when you use a BTnet leased line. We use Direct Private Peering, so traffic doesn’t pass over the public internet, and our low latency network minimises lag for unrivalled performance.
How is a leased line different to broadband?
When you have a broadband connection, you share your bandwidth with others. That means if the business next door is going through a busy spell, you might end up experiencing delays on your network. A business leased line, on the other hand, is a dedicated line just for you. That means you don’t need to share it with anyone else, so there’s no risk of lags when you’re on that all-important video call.
How long does it take to set up a BTnet leased line?
Every business is different, and although we’ll work with you to get your leased line up and running as quickly as possible, it is subject to survey. Get in touch with our team today for a forecast.
What is a product carbon footprint and how is it calculated?
A product's carbon footprint is the total greenhouse gas emissions it produces. It includes the extraction of raw materials all the way through to disposal and recycling.
This information is important as it allows you to understand the environmental impact of a product. We’re showing this data to help you make more informed purchasing decisions and take steps towards a more sustainable future.
We use product carbon footprint data which is calculated according to the ISO Greenhouse Gas Assessment Standard for the Life Cycle Phase of Products and Services. These calculations are in line with GHG Protocol methodology.
