Fast, reliable internet is no longer a luxury—it’s essential if you’re running a small startup or managing a growing enterprise. We know that in 2025, your business needs a connection that can handle video calls, cloud services, data backups, and more.
If your current broadband feels slow or inconsistent, you might have heard about leased lines as a better solution, so we’ll explain exactly what a leased line is, how it works, and why more UK businesses are switching in 2025.
📡 What Is a Leased Line?
A leased line is a high-speed internet connection delivered directly from your provider to your business premises, giving you dedicated internet connections. It isn’t shared with other users, making it different from regular broadband—so your speed and performance stay consistent, even at peak times.
The line is “leased” (rented) from the provider, which is why it’s called a leased line.
characteristics of a leased line:
- Dedicated connection just for your business
- Symmetrical speeds – same upload and download rates
- Guaranteed uptime and service level agreements (SLAs)
- Scalable speeds from 100Mbps to 10Gbps+
🔁 Leased Line vs Standard Business Broadband
Let’s break it down with a simple comparison:
| Feature | Leased line | Business broadband |
|---|---|---|
| Connection Type | Dedicated (not shared) | Shared with others |
| Speed | Symmetrical (up/down) | Asymmetrical (download faster) |
| Reliability | Very high (99.9% SLA) | Varies, especially during peak |
| Cost | Higher | Lower |
| Installation Time | 30–90 days | 5–14 days |
| Ideal For | Growing SMEs, remote teams | Basic business needs |
⚙️ How Does a Leased Line Work?
When you order a leased line, your provider will install a dedicated fibre connection straight to your building from their nearest network point. This line isn’t shared with neighbouring homes or businesses.
You’ll typically receive a router or firewall and a static IP address, allowing your team to:
- Host websites or servers
- Run secure VPNs for remote working
- Use VoIP phone systems
- you can transfer large files without lag
- And access cloud tools like Microsoft 365, Google Workspace, etc.
✅ Who Needs a Leased Line?
Leased lines are ideal for UK businesses that:
- Rely on fast, stable connectivity every day
- Run cloud-based applications (CRM, HR, accounting)
- Host servers or websites internally
- Make frequent video calls or use VoIP
- Need guaranteed uptime and rapid support
Some of our favourite examples include:
- Law firms and accountants need secure, constant access to cloud files
- E-commerce companies whoneed to process orders 24/7
