What Is Business Broadband?

Business broadband works in the same way as home broadband, but with a few key differences. It runs over a shared network infrastructure, which means your connection is shared with other businesses and households in your area. Consequently, speeds can vary depending on how busy the network is — particularly during peak hours.

Business broadband is available in several forms:

FTTC (Fibre to the Cabinet) — fibre runs to the street cabinet, then copper wire carries the connection to your premises. As a result, speeds are limited by the quality and length of that copper run. Most businesses get download speeds of 30–80Mbps on FTTC.

FTTP (Fibre to the Premises) — full fibre runs directly to your building. Therefore, speeds are significantly faster and more consistent, with many providers offering 100Mbps to 1Gbps download speeds.

SoGEA — a single-order broadband product that delivers FTTC speeds without a traditional phone line. It is the most common replacement for older ADSL connections following the PSTN switch-off.

Business broadband is widely available, straightforward to set up, and affordable. However, it comes with limitations that some businesses will quickly run into.

What Is a Leased Line?

A leased line is a dedicated, private connection between your premises and the internet. Unlike business broadband, it is not shared with anyone else. Furthermore, leased lines deliver symmetrical speeds — meaning your upload speed matches your download speed exactly.

For example, a 100Mbps leased line gives you 100Mbps download and 100Mbps upload, consistently, at all times of day. Additionally, leased lines come with a guaranteed service level agreement (SLA), which means your provider commits to uptime and response times in writing.

Leased lines are available from 100Mbps up to 10Gbps, depending on your requirements and location.

Business Broadband vs Leased Lines: Key Differences

When Business Broadband Is the Right Choice

Business broadband is the right choice for most small businesses. Specifically, it works well when:

• Your team is small and internet usage is moderate
• You use cloud tools like Microsoft 365 but do not transfer large files regularly
• Budget is a priority and you do not need a guaranteed uptime SLA
• Your business can tolerate occasional slowdowns during peak hours

For many SMEs, a well-specified FTTP business broadband connection delivers everything they need at a fraction of the cost of a leased line. Moreover, adding a second broadband connection as a failover is a cost-effective way to improve resilience without committing to a leased line contract.

When a Leased Line Is Worth the Investment

A leased line makes sense when your business depends on its internet connection for critical operations. In particular, consider a leased line if:

You rely heavily on cloud-hosted applications. If your phone system, CRM, ERP, or hosted desktop all run over the internet, a consistent and symmetrical connection is essential. Consequently, a leased line eliminates the bottleneck that shared broadband creates.

You transfer large files regularly. Upload speeds on standard broadband are asymmetric and often slow. Therefore, businesses that send large files — design agencies, video production companies, engineering firms — benefit significantly from symmetrical leased line speeds.

You host your own servers or services. If you run on-premises servers that remote staff or clients connect to, upload speed and consistency matter as much as download.

You cannot afford downtime. A leased line SLA typically guarantees uptime of 99.95% or above, with engineers dispatched within four hours if something goes wrong. For businesses where downtime costs thousands per hour, that guarantee is worth the premium.

You have multiple users with high simultaneous demand. On a shared broadband connection, bandwidth is divided between users. However, on a leased line, every user gets the full benefit of the connection regardless of how many people are online at once.

What About Bonded Broadband?

There is a middle ground worth knowing about. Bonded broadband combines multiple broadband connections into a single, faster pipe — delivering improved speeds and resilience at a lower cost than a leased line. It is a practical option for businesses that need more than standard broadband can offer but are not yet ready for a full leased line commitment.

How Much Does a Leased Line Cost?

Leased line pricing depends on your location, the speed required, and the provider.

Installation costs vary but are often included or subsidised by providers on longer contracts. Furthermore, prices have dropped significantly over the past five years as infrastructure investment has increased — particularly across Essex and Kent.

Via Wire provides leased lines across Essex and Kent, with full installation management and ongoing support included. You can find out more on our leased lines page.

Business Broadband vs Leased Lines: Which Should You Choose?

The honest answer is that it depends on how your business uses the internet. If your connection is primarily for email, browsing, and light cloud use, business broadband — particularly FTTP — will serve you well. However, if your business depends on its connection for hosted applications, large file transfers, or real-time communications, a leased line is likely the better long-term investment.
