Business Leased Lines

Your business depends on a reliable connection.

With a dedicated leased line from 39D, you get uncontended bandwidth — meaning your connection is used only by you. That means faster upload and download speeds, lower latency and guaranteed performance whenever you need it.

Unlike standard broadband, leased lines deliver symmetrical speeds and a rock-solid connection that won’t fluctuate during busy periods. They’re ideal for businesses running cloud applications, video conferencing, VoIP systems or large data transfers.

At 39D, we manage the entire process — from survey and installation to monitoring and maintenance. You’ll get a single point of contact, clear pricing and dependable support from our UK-based team.

What is a Business Leased Line?

A leased line is a dedicated internet connection reserved solely for your business, not shared with other users like standard broadband. It offers consistent, high-performance connectivity with equal upload and download speeds — perfect for organisations that rely heavily on online services and cloud applications.

Every leased line we install includes monitoring, maintenance and a defined Service Level Agreement (SLA) guaranteeing uptime and response times. If something goes wrong, our engineers act immediately to keep you connected.

Leased lines are ideal for:

  • Businesses needing guaranteed uptime and performance
  • Teams using cloud platforms, VoIP, or video conferencing daily
  • Organisations transferring or backing up large volumes of data
  • Companies with multiple sites requiring stable connections
  • Any business frustrated by unreliable broadband speeds

Answer

How is a leased line different from broadband?

Broadband is shared between multiple users, so speeds fluctuate. A leased line gives you dedicated, symmetrical bandwidth and guaranteed uptime.

What speeds can I get?

We offer scalable speeds from 100 Mbps to 10 Gbps, depending on your location and requirements. We’ll recommend the right option for your usage.

Is installation included?

Yes. We handle the full process — site survey, installation, configuration and testing — with transparent pricing and timelines.

What happens if the line goes down?

Our SLA guarantees rapid response and fix times. Our engineers monitor your line continuously to detect and resolve issues before they affect you.

Can I combine a leased line with other 39D services?

Absolutely. Many clients pair leased lines with our Managed Wi-Fi, Firewalls, and Hosted Telephony for complete, business-grade connectivity.

Our clients say...

Cannot recommend this company highly enough. Matthew talked me through an IT issue I was having patiently and professionally and all was corrected within just a few minutes. I am a total technophobe so was worried I wouldn't understand what I was being told, I was totally wrong. Clear, precise and in terms even I understood. Would definately use this company again. Five star service.

39D IT Support is so useful for me in my everyday life running a small business. I can call any time to ask for help with my computer systems and someone knowledgeable will answer politely and efficiently. Their service, in my opinion, is second to none. John

We've been using 39D for IT Support for 2.5 years now and they've been absolutely brilliant. They do everything from setting up new equipment, troubleshooting an issue, or offering advice on the best solutions for my business and they're always professional and reliable. Would definitely recommend them to anyone looking for solid IT support.

Since 39d changed our phones over our experience has been a lot better, easier access to the phone book from my pc as well as the phone. Easy to store numbers in a click. Pick up and transfer are much easier too.the whole service is a lot better than it was before. Not forgetting the staff are helpful and efficient and polite at all times ????

Matthew and his team have been solving our problems here at Rainbow Estate Agents successfully for the past 5 years or so. No reason to complain and happy to recommend
Alex Smith
This company goes above and beyond to support its clients. Being one of them i have never experienced a more robust support when it comes to IT infrastructure. The advice they give is honest and trustworthy and the speed in which they deliver the ongoing support is amazing. I would highly recommend anyone who is not happy with their current arrangements to contact the team at 39D. If you are yet to invest in protecting your businesses online presence, then make this company your first point of contact.
Sean Hewitt
We have just moved to 39D and I have been VERY impressed with the service we are receiving. Considering we had a huge data merge to undertake they have been patient, quick and very knowledgeable. In particular Matthew, Jake and Chloe have been extremely helpful. We are looking forward to their continued service and expertise.
Tracy Askew
Having a major breakdown on sending and receiving emails. Which is a clearly a problem when running your own business. Also with numerous issues with my IT, I finally decided to try 39d. I was a little apprehensive - I had paid two different companies to try and rectify my problems. Within a morning my emails and IT had been resolved I have now signed up to D39. I can�t tell you how relieved to know that should I have a problem I just have to call D39 and they are there at the end of the phone. Matthew explains in terms I can understand. Highly recommended.
