So, to find out what is a good internet speed and whether you need to upgrade broadband deals, we're going to break it down in a bit more detail so you can apply the results to you. But if you've got a house full of gamers and 4K video streamers, you're going to want a line with a bit more grunt. If you're just checking emails and browsing the odd website, you can probably get away with low speeds and not even notice. It's also worth noting that what may be a good internet speed for one person could be totally useless to another. And where there was once grainy 720p video at best, now we stream in glorious 4K and HDR – all needing more internet bandwidth than ever. Home security once meant a dedicated system with solid backup but now you can stream to your phone from anywhere. As such a good speed is relative to what you need.īack in the day music and video were stored offline, but now they're streamed. In fact if you asked it two years ago you'd see a huge jump. If you asked this question ten years ago the answer would be hugely different to today. To know if you have good internet speed, you first need to know what actually is classed as a good internet speed.
