Turbo-charged download speeds

GFast can seriously turbocharge your speed. At 330Mbps, you can download a 4K movie in under 6 minutes, or 100 of your favourite songs in under 20 seconds.

Fast upload speeds

With these kind of upload speeds, video calls are smooth and glitch-free, and you can upload files without skipping a beat. At 50Mpbs, a 2GB file will upload in under five and a half minutes.

Biggest choice of service providers in the UK

Our broadband network is ‘open’ - so you’re never tied down to one service provider. Over 650 service providers use our network, including Sky, BT, Vodafone, TalkTalk and Plusnet, so you can always choose the broadband package that suits you best.

Great for families

GFast is great for streaming the latest movies in 4K, chatting on video calls, and kicking back with some online gaming. If you're into virtual reality or serious gaming, have a big household with lots of devices, or regularly upload videos to Youtube, it’s a good idea to consider Ultrafast Full Fibre broadband instead. We're rolling this out to 25m homes and businesses by December 2026 and we connect someone to Full Fibre every 10.4 seconds.

Your choice of phone line

It’s possible to get GFast with a digital phone line, an analogue phone line, or even no phone line at all.

Phoneline options you get with Gfast Broadband

Digital phoneline A digital phone line uses your fibre broadband connection instead of the copper telephone network. It means that your phone calls will be made using the same technology as when you use WhatsApp, Microsoft Teams, Zoom, and Skype. Because it’s digital, you’ll be able to use your landline while you’re on the go and may have access to cheaper calls and premium features, like Anonymous Call Barring and Call Divert.

Analogue phone line An analogue phone line uses the copper telephone network – it’s the system we’ve been using for over a century. While it’s served us all well, it’s time for an upgrade – which is why we’re phasing it out gradually, before switching it off in 2025. It’s worth bearing that in mind when making your choice of which type of phone line you want to use for your broadband.

No phone line If you want broadband but aren’t interested in a phone service, it’s possible to order both Superfast and Gfast without a phone line. You’ll need to check with your chosen service provider to make sure they offer this option.

What happens once you order?

How we’ll install your Gfast

If GFast is available for your home or business, and you already have Superfast, you’ll need a simple upgrade. An engineer will visit you and your local cabinet to install and enable GFast technology. Your service provider might also send you a new router.

If GFast is already enabled, simply order a new router from your service provider and you’ll be ready to go.
