What Broadband Speed Does My Business Need?

The number of users is a useful starting point, but it is not the whole answer. Ten staff using email and a browser may place less strain on a connection than three staff uploading design files or joining video calls all day.

When comparing options, think about how many people use the connection at the same time, what devices they use and whether visitors or customers also share the network.

VoIP calls need stable connectivity, low latency and enough upload capacity. Call quality can suffer if the connection is busy, the router is overloaded or Wi-Fi coverage is weak.

Video meetings can use much more bandwidth than voice calls, especially when several people are on calls at the same time. If meetings are important to your business, compare upload speed, download speed and stability rather than looking only at headline download speed.

Cloud accounting, CRM systems, booking platforms, remote desktops, backups and shared drives all rely on consistent connectivity. They may not always need the highest download speed, but they do need a stable connection during working hours.

File uploads are often where slower connections become frustrating. Sending large documents, design files, media, database backups or CCTV clips can place real pressure on upload speed.

CCTV can affect broadband needs where cameras are viewed remotely, backed up to cloud storage or monitored across multiple sites. Local recording may reduce internet usage, but remote access and cloud features still need to be considered.

Guest Wi-Fi can also create unpredictable demand, especially in pubs, hotels, care homes, waiting rooms and customer areas. Card terminals may use little bandwidth, but they are business-critical, so reliability and backup can matter more than raw speed.

Download speed affects how quickly users receive data, such as loading websites, downloading files or using cloud applications. Upload speed affects sending data, video calls, VoIP, backups, CCTV access and file sharing.

Latency is the delay in the connection. High latency can make VoIP calls, remote desktops and video meetings feel poor even where the headline speed looks acceptable. A good comparison should consider all three: download, upload and latency.

Many broadband problems appear at peak times rather than all day. A connection might feel fine early in the morning but struggle when staff, phones, cloud apps, visitors and connected devices are all active together.

List the busiest periods in your working day and the systems used at those times. This helps separate a connection that works in theory from one that supports the business during real trading conditions.

Backup connectivity may be worth considering where broadband supports phones, payment systems, bookings, cloud software, remote access or CCTV. Options might include 4G or 5G failover, a second broadband service or a more resilient connection design.

Backup does not remove every risk, but it can help reduce disruption if the main connection fails. For some businesses, resilience is more important than choosing the highest headline speed.

A leased line may be worth comparing if your business needs dedicated connectivity, stronger service expectations, symmetrical speeds, heavy upload use, reliable VoIP, remote access or multi-site connectivity.

A leased line is not necessary for every business, and it should not be chosen only because it sounds more robust. Compare it against FTTP business broadband, backup options, installation requirements and the cost of downtime for your organisation.

Before comparing quotes, gather your postcode, number of users, number of sites, current provider, current monthly spend, contract end date and any problems with speed, Wi-Fi, calls or reliability.
