Three UK will offers a full refund if you're unhappy with its full-fibre rival in the first 30 days

Struggling with dismal broadband speeds, and want to switch to something new?

Three UK might be best known for its mobile network, but the brand also offers fast home broadband.


Unlike internet suppliers like BT, Sky Broadband, and Vodafone, which rely on fibre-optic cables buried in the ground and connected to homes and businesses across the UK, Three takes a very different approach. Instead, it leverages its award-winning 5G network to deliver full-fibre broadband speeds to your home.

There's no need to organise a visit from an engineer to drill holes in your walls and connect any new cables.

Three UK's Wi-Fi router has a small SIM card inside – exactly like a smartphone – that taps into the fast internet speeds available over the 5G network. Better yet, since there's no cable, you can move the plug-and-play router around your house to fit the perfect spot for coverage to all rooms and devices.

With an average download speed of 150Mbps, you'll be able to stream Netflix in 4K UHD (15Mbps minimum), make a high-quality video call on WhatsApp (4Mbps minimum), or watch live footage from your Ring video doorbell (2Mbps minimum) all at the same time without any hiccups or buffering.

Three Home Broadband blasts away the old-school setup drama with genuinely plug‑and‑play, 5G‑powered internet that needs no landline, no engineer and no endless waiting. Order before 8 pm, and you’ll have your hub by the next working day — just plug it in, and your home Wi-Fi will be powered by "the UK’s fastest 5G network" in minutes, the mobile network promises. Three UK even offers a 30 day money-back guarantee for new subscribers

While the method of delivering an internet connection to your router is pretty different with Three UK compared to other broadband provider, it shouldn't make a difference once you're connected to the Wi-Fi beamed out by the router.

If you're a little skeptical about whether a 5G-fuelled Wi-Fi connection can compete with a traditional underground cable — you're not alone. Three UK is clearly aware that it might have to work hard to convince you to make the switch, so it's offering a 30-day money-back guarantee on its home broadband solution. Yes, really.

Depending on the mobile coverage in your local area, Three UK's broadband will be delivered via 4G or 5G. The latter offers faster speeds, with an average download speed of 150Mbps. For comparison, Ofcom measured the average household broadband speed in the UK at 223Mbps last year, so you'll be a little under the average.

But when it comes to monthly cost — your 5G-powered broadband will be well below average.

Three UK usually charges £21 a month for its 5G broadband. There's no landline included as part of the package, so regardless of whether you don't want the hassle of hvaing a landline installed, don't fancy answering to endless spam calls, or are unable to get a landline where you are, Three UK has you covered.

If you want to ensure that broadband speed covers every room in your home, Three UK has partnered with eero — the Amazon-owned brand that builds mesh Wi-Fi systems designed to eliminate all Wi-Fi dead-zones throughout your home.

The award-winning US company, which recently launched its most affordable Wi-Fi 7 range to date, will even include its eero Secure subscription as standard for all Three UK broadband subscribers, so you'll be able to access features like automatic malware blocking and temporarily pause the internet for specific people or devices at scheduled times.

TalkTalk has also partnered with eero to bring its speedy and reliable Wi-Fi coverage to its full-fibre subscribers, ditching the traditional method of developing its own wireless routers, like BT, Virgin Media, Sky Broadband, and others.
