published: 2nd February 2024 updated: 20th November 2025

Choosing new broadband can be a little confusing and overwhelming when it comes to speeds and prices, and then you face complicated industry jargon too!

There are many aspects that might influence your decision , from affordability to how reliable the service is.

One element that can lead to confusion is the promise of high broadband speeds, especially with the introduction of gigabit broadband speeds over the last few years. While it sounds great to be able to access the highest speeds, many are often left asking themselves if they really need those speeds.

We’ll be breaking down the benefits of 900 Mbps download and upload speeds and answering is 900 Mbps fast?

what does Mbps mean?

Mbps, or megabits per second, is the measurement used to show just how fast your internet connection really is. Each megabit per second equates to transferring 1 million bits each second, which is around the size of one small photo file.

what does 900 Mbps mean?

With this logic in mind, when using a high speed full-fibre broadband service that offers 900 Mbps, you can transfer the equivalent of 900 small photo files in a single second.

Day-to-day, your downloads will complete more quickly, webpages will load faster, and streaming music, videos or games will be a smoother process with less likelihood of buffering or issues while playing.

what are the UK’s average download & upload speeds?

In the UK, the average download speed is 69.4 Mbps whilst the average upload speed is just 18.4 Mbps1. However, there are a few issues when you consider these speeds.

Low download speeds will cause a lag when downloading ‘heavy’ content (for example a movie, a PDF, or a high-resolution image). In terms of a low upload speed, you will face a delay when sharing content, information or files online. In addition, if you share a household with other highly active internet users, a poor connection can also cause significant delays in the way you access the files and information that you need.
