Many broadband providers refer to download speeds when advertising their services, because in general people are passive consumers of online content. So upload speeds aren’t always that important to people, but they really should be.

When we view our Instagram timelines, play Call of Duty, Fifa etc or watch content through BBC iPlayer, ITV Hub we’re downloading reams of information to our devices.

However, computers and other web-enabled devices are also sending information all the time, from emails and video chats to requests for the next chunk of a Netflix video.

No one puts upload in the corner

Look upload, not download

Broadband providers recognise this, but they’re also aware that consumers generally spend much more time downloading than uploading. For instance, most of the emails you handle in a typical day will be sent to you, rather than sent by you. Internet service providers tend to bias broadband connections in favour of downloads – often by ratios as high as ten to one. In other words, it’s ten times faster to download a particular file than it would be to upload it.

However, we are increasingly moving towards an always-on society and as a result, upload speeds are more important than they’ve ever been.

Why fast upload speeds matter

Even though consumers download more than they upload by definition, these are some of the common reasons for uploading data:

  • Sending emails, particularly ones with attachments
  • Voice calls and video conferencing, using platforms like Skype and Teams
  • Playing online games, where your device has to update servers with your current status and progress
  • Streaming media from iPlayer or YouTube, for the same reason
  • Backing up data to online storage services aka the Cloud
  • Confirming receipt of information – internet browsers do this constantly when loading website pages
  • Making status updates via social media, particularly photo or video messages
  • Working on cloud-hosted documents in packages like Office 365

If any of these are a significant part of your daily life, it’s advisable to research typical upload speeds in your postcode before signing up with a new broadband provider – in the same way you might check download speeds if you’re an avid gamer or Netflix addict.

Upload speed is just as spectacular as download speed

How to measure upload speeds

Take a speed test here

The first figure will be your download speed, but the second will identify your upload speed – and it’ll be much lower.

How fast is that?

These figures are reported in megabits per second (Mbps).

A megabit is one eighth of a megabyte – the unit of measurement used for computer files, software downloads and much more besides. An internet connection at 8Mbps can only download a maximum of 1MB of data per second.

In reality, it would be far slower due to line congestion, the effects of WiFi, less efficient software on the recipient device, and so forth.
The same is true for uploads. If your maximum upload speed is 8Mbps, you’ll need a minute to upload a 60MB file in perfect conditions – in reality, it might take 10 times longer.

Ofcom conducted a major survey in 2016 that found the typical upload speeds for an “up to 50Mbps” cable service are just 3Mbps. They concluded the UK had an average upload speed of 3.7Mbps, increasing to 4.3Mbps in urban areas but falling to 1.6Mbps in rural regions.

In truth, anything over 1Mbps will be sufficient for sending emails and ensuring web browsers can communicate with host servers. However, you’ll notice this sluggish performance if you’re trying to send an email with a couple of JPG attachments, or chat to your cousin in Australia via Skype.
