Business Broadband Speed Guide

Choosing the speed of your next business broadband package requires a fine balance. A slow connection can cause significant productivity issues, while a package that is too fast may be unnecessarily expensive.

This guide aims to provide you with all the information you need to choose the right broadband speed for your business. Here’s what we cover:

Business broadband speed calculator

Our business broadband speed calculator estimates the minimum speed requirement for your business from a few simple questions about how your business uses the internet. We’ll also recommend a connection type that supports the speed your business requires.

What determines my business broadband speed?

Here, we summarise the four main factors determining the broadband speed your business broadband users receive.

Connection type

The technology used to connect your business to the internet is the biggest determinant of the broadband speed your business receives.

The table below shows all the business broadband connection types available in Britain, including their top speeds and availability.

Connection TypeTop PerformanceAvailability
ADSL Broadband
Up to 20 MbpsNear universal
5G Business BroadbandUp to 150 Mbps (variable!)Most towns and cities
Satelitte Business BroadbandUp to 200 MbpsUniversal

Cable BroadbandUp to 1,000 Mbps60% of UK properties
Full Fibre BroadbandUp to 1,000 Mbps70% of UK properties
Leased Line BroadbandUp to 10,000 MbpsMajority of the UK

Your business broadband package

Business broadband deals are typically advertised with a range of speeds, with the monthly cost increasing with the chosen speed.

Often, the simplest way to get more speed is to upgrade your current broadband package to a higher speed tier.

💡Ofcom has published a broadband speed advertisement code of practice that requires providers to give accurate information about expected broadband speeds. However, only BT, TalkTalk, and Virgin Media Business Broadband have signed up to this.

Number of users

The speed offered by your broadband connection is shared among all connected devices.

The more active users you have connected to your broadband, the slower the speed each user will receive.

💡Most routers come equipped with QoS (Quality of Service) that prioritises activities like VoIP calls, which require a minimum speed to guarantee quality.

Network congestion

Business broadband providers must manage network congestion during peak times when too many users overload their infrastructure.

Broadband providers use throttling to reduce speed availability to manage network congestion.

Business broadband deals are typically more expensive because providers prioritise business traffic over domestic traffic during network congestion.

Benefits of faster business broadband speeds

Here are the three principal benefits of a fast and reliable business broadband connection:

  • Productivity – Most businesses now rely on cloud-based services for storage, workplace, and project management software. Reliable high-speed internet guarantees access to these tools.
  • Communication – The PSTN switch-off is moving companies to digital business phone lines. Reliable high-speed broadband is crucial for virtual meetings and client communications.
  • Customer experience – Customers expect to be able to use guest WiFi. Having sufficient broadband speeds enables small business broadband customers to offer guest WiFi alongside their internal network.

Measuring business broadband speed

Here’s a quick explanation of the different metrics measured by our business broadband speed test:

  • Download speed – The speed at which information is transferred from the internet to your device, measured in Mbps.
  • Upload speed – The speed at which your device’s information is transferred onto the internet or another server, also measured in Mbps.
  • Ping – The number of milliseconds taken to transfer data from your device to a server and back again; a measure of latency.
  • Jitter – A measure of the consistency of latency on your business broadband connection.

Our broadband speed calculator is great at giving you a feel for your business broadband requirements.

The next step is to make a more detailed study of what is actually happening at your premises. Consider the bandwidth requirements of all your online activities happening simultaneously, including the use of your guest WiFi by visitors and your employees’ personal devices.

Here is a list of the recommended speeds for typical business activities:

Optimising business broadband performance

Our experts summarise three important considerations for improving your business broadband performance:

Hardware and wiring

Use a wired Ethernet connection for stationary devices, as business broadband speed quickly drops with distance from the WiFi router.

If a wireless connection is necessary, consider the positioning of your business broadband router. The speed of your connection will be diminished by walls and other obstructions that your wireless signal must travel through.

If you have ample office space, consider using a mesh network of multiple routers to ensure strong signal coverage throughout the building.

It’s also worth considering upgrading your router and network setup (e.g. SD-WAN), as newer devices offer stronger performance.

Broadband redundancy

It’s important to consider a backup internet connection in case of an issue with your primary business broadband connection.

For small businesses, the best business broadband redundancy option is a 4G-enabled business broadband router that uses mobile broadband as a backup.

For larger businesses, a secondary backup tethered connection is preferred as its usually more reliable. It can also serve as a load-balancing auxiliary to improve the bandwidth and reliability of your network (e.g. route the Guest WiFi traffic through the less performant secondary connection to leave more bandwidth for the primary!)

Broadband scalability

When arranging a new business broadband installation, consider your future speed requirements to ensure your business is well-positioned for the future.

A scalable business broadband connection can be quickly and easily tweaked to provide additional bandwidth as your business grows. Refer to our full article on business broadband scalability for more information.
