BT Full Fibre 100 has a download speed of 150 Mbps ⬇ and an upload speed of 30 Mbps ⬆. This is actual full fibre, meaning it’s fibre all the way from the BT exchange to your premises. It’s a vast improvement over some of the slower BT broadband packages like Fibre 1, Fibre 2, and Fibre Essential, which are earlier versions of fibre called Fibre to the Cabinet (FTTC).
Remarkably, it’s three times faster than BT Fibre 1 but costs only £2 more monthly. What does that mean in real terms? Well, it means that you can download 100 megabytes of information in 8 seconds, or to put it in gaming terms, you can download Fortnite (29.2 gigabytes) in roughly 42 minutes with a BT Full Fibre 100 Mbps connection.
This broadband-only package with a 24-month contract, priced at £30.99 per month, is exceptional value. It provides a high-speed, ultra-low latency connection of 7-8 ms, ideal for smooth browsing, uninterrupted HD streaming on multiple devices, gaming, and crystal-clear video calls.
The low latency achieved with a full-fibre connection directly to your home eliminates the typical slowdowns caused by traditional copper cabling found in standard fibre connections. This ensures consistent and ultrafast speeds, even in rural areas.
This review includes information on whether BT Full Fibre 100 is suitable for your needs and how it compares with other broadband packages. We strongly believe this package is perfect for most people. It is comparatively more affordable and provides a high-speed internet experience that meets work and entertainment demands.
There are around 58 variations of sub-packages that you can create from the BT Full Fibre 100 deal, depending on how you customise your package. That ability to customise alone makes this deal attractive, but you’ll find the same ability on other BT Broadband deals such as the 300, 500, and 900.
Generally speaking, BT Full Fibre 100 is your best value-for-money option in the BT range. But that depends on some nuances like the promotional package you purchase (occasionally there’s £50 reward card) and, crucially, the timing of your purchase as the monthly cost fluctuates frequently. For instance, the cost of this package was initially £34.99 and dropped to £30.99 towards the end of last year. It then briefly dipped to £28.99 before returning to £29.99. It has now peaked again £34.99 per month, with a 24-month contract that increases on 31st March.
Value for money comes down to the availability of providers in your area. There are several other competitive packages available around the same speed range, including BT-owned Plusnet Broadband. For £25.99 per month, you can get Plusnet’s Full Fibre 145 , which is a whole £9 cheaper than Full Fibre 100 and is only slower by 5 Mbps. Plusnet operates as an independent brand but is part of the BT Group. You might also want to look at equivalent packages from providers like Virgin (particularly M125) and even some of the Altnets like Lit Fibre (see Lit 100)
Key Takeaway: BT Full Fibre 100 offers a good range of performance but is not the cheapest. With prices currently at £34.99 per month, it’s not a great time to buy. BT reviews its prices regularly, so it’s recommended that you stay updated on any changes.
