BT Full Fibre 100

In addition to its standard fibre speeds, BT has now broken into the ultrafast market with its introduction of full fibre broadband packages. With speeds that range from 100Mbps to 900Mbps, BT is now a serious rival to Virgin Media when it comes to speed.

BT’s Full Fibre packages use fibre cabling all the way to your property, rather than connecting the last stretch from your local street cabinet to your home by copper wiring, which is what is used for standard fibre connections. This means Full Fibre can offer even faster speeds with none of the slowdown caused by copper cabling.

BT Full Fibre 100 is the lowest full fibre speed on offer from BT, but, averaging 145Mbps, is still double the speed of BT’s Fibre 2 package, which offers an average of just 62Mbps. In this guide we take a look at who should think about getting BT Full Fibre 100 and what you can do with this kind of speed.

Who is BT Full Fibre 100 for?

BT Full Fibre 100 offers a good chunk of extra speed for anyone who is finding a top-end fibre package of around 76Mbps not quite enough. It is BT’s entry-level full fibre product and comes with an average download speed of 145Mbps – somewhat more than the advertised name would suggest, which means an even bigger jump in speed.

Here’s a brief overview of the kind of household or individual who would benefit from getting BT Full Fibre 100:

  • Households with 2-4 occupants – 100Mbps or more will comfortably support up to four people online at the same time, depending on how they use the connection
  • Gamers – Although a very low download speed of 3-5Mbps is required for most online multiplayer games, a faster connection will ensure any gamers have minimal disruption from other online activities and will also allow large games to be downloaded rapidly. A fast upload speed will also come in useful in limiting lag time.
  • Video streamers – If you like to watch a lot of online content, via streaming sites such as Netflix, YouTube and Disney+, a fast download speed will ensure a smooth viewing experience, especially if more than one member of your household is watching at once, or if you like to watch in 4K.
  • Cloud storage – If you use cloud storage of any kind for saving photos or sharing files, then a fast, full fibre download speed (and a decent upload speed) will make this task a speed one
  • Several devices – The more devices your household has, the higher a download speed you will need. Depending on what you do online, a 100Mbps download speed should comfortably support up to ten devices
  • Live streamers – If you regularly live stream content and upload to streaming sites, you will need an upload speed of 5-15Mbps, so 100Mbps will comfortably enable you to do this without interruption whilst also keeping other devices online.

What we think

BT Full Fibre is now rolling out across the country and, for those who can get it, it presents a great alternative to Virgin Media. Full Fibre 100 is an ideal speed for many households, although large households or those that do a lot of streaming may benefit from a higher Full Fibre speed. All BT broadband packages can be bundled with BT TV, which comes with NOW TV Entertainment and Netflix as standard, and sports fans can add on BT Sport and Sky Sports too.

On the downside, BT Full Fibre contracts tie you in for 24 months, which is considerably longer than the 18-month contracts available from Virgin Media and Sky. Plus, BT Full Fibre is not yet available everywhere, so you may not be able to get it at your property yet. However, you can ask BT to keep you notified as to when Full Fibre will be arriving in your area so you can switch as soon as it becomes available.
