Few decisions affect your day-to-day productivity as much as the internet connection sitting behind your business. Get it right and nobody thinks about it. Get it wrong and every video call, cloud app and file upload becomes a source of frustration. The choice usually comes down to two options: business broadband or a leased line. Here is how to tell which one your business actually needs.
The fundamental difference
Business broadband is a shared connection. You share capacity with other homes and businesses in your area, which keeps the price low but means speeds can dip at busy times. A leased line is a dedicated connection reserved entirely for your business, with the same speed guaranteed up and down, around the clock.
Think of broadband as a busy motorway shared with everyone else, and a leased line as your own private lane that never gets congested.
How they compare
| Feature | Business Broadband | Leased Line |
|---|---|---|
| Connection type | Shared | Dedicated |
| Speed | Variable, "up to" | Guaranteed, symmetric |
| Upload speed | Usually slow | Same as download |
| Typical fix time | 1-3 days | A few hours (backed by SLA) |
| Cost | Low | Higher |
| Best for | Small teams, light cloud use | Heavy cloud, VoIP, larger teams |
When business broadband is the right call
For many small businesses, modern full fibre (FTTP) business broadband is more than enough. If you have a handful of staff, use email and a few cloud apps, and can tolerate the occasional slow spell, broadband offers excellent value. The arrival of full fibre across the UK has made these connections far faster and more reliable than the old copper services.
When you need a leased line
A leased line earns its higher price when downtime costs you money. If your phones run over hosted telephony, your team relies on cloud systems all day, or you upload large files regularly, the guaranteed symmetric speeds and rapid fix times of a leased line quickly pay for themselves. We explain the detail in what is a leased line.
Don't forget resilience
Whichever you choose, a single connection is a single point of failure. We strongly recommend pairing your primary line with 4G/5G failover so your business stays online even if the main connection drops.

Frequently asked questions
What is the difference between business broadband and a leased line?
Business broadband is a shared connection with variable speeds, while a leased line is a dedicated connection with guaranteed, symmetric speeds reserved entirely for your business.
Do I need a leased line or is broadband enough?
If downtime seriously costs you money or you rely heavily on the cloud and VoIP, a leased line is worth it. For lighter use, modern full fibre broadband is often enough.
Why is a leased line more expensive?
You are paying for dedicated, guaranteed bandwidth and a strong service level agreement with rapid fix times, rather than capacity shared with others.
