What has changed with Three home broadband?
Three has been cutting the price of its 5G home broadband. ISPreview reported on 14 October 2026 that the unlimited 5G plan on a 24 month contract had come down to £15 a month, with either an indoor router or an outdoor hub plus a mesh Wi-Fi unit depending on the option you pick. We could not open that article when we checked on 16 October 2026, so treat the £15 as reported rather than confirmed.
What we can confirm is Three’s own home broadband page, read on 16 October 2026. It listed the 24 month unlimited plan at £18 a month and the 12 month unlimited plan at £24 a month. Those are the figures this page is built on, because they come from Three.
Either way, it’s the sort of price that makes the Do-Nothing Default look expensive. But a low monthly figure is only the opening line. Two things sit behind it: a payment condition, and a pair of price rises already written into the contract.
Is there a condition attached to the price?
Yes, and it is easy to miss. Three says your monthly charge includes a £5 discount for paying by a recurring method, such as Direct Debit. So £18 is the Direct Debit price, not the standard one.
Pay by another method and the monthly cost is higher. Three doesn’t publish that higher figure on its home broadband page, so ask for it before you order if you’d rather not set up a Direct Debit. Over a 24 month term, £5 a month adds up to £120.
Every price on this page, including the April rises and our own sums below, is a Direct Debit price.
How much does Three home broadband cost over 24 months?
Three home broadband costs more than the headline price once the April rises kick in. Both prices we found include rises set out in the contract.
Three’s own page says the plan it listed at £18 rises to £21.50 from 1 April 2027 and £25 from 1 April 2028. It also says all home broadband plans increase by £3.50 a month. ISPreview’s reported £15 plan follows the same ladder, rising to £18.50 from 1 April 2027 and £22 from 1 April 2028.
Key takeaways
- Three’s own page listed £18 a month on a 24 month plan on 16 October. ISPreview reported £15.
- Both prices include a £5 discount for paying by a recurring method such as Direct Debit.
- Three says all its home broadband plans rise by £3.50 a month, in April 2027 and again in April 2028.
- The 12 month plan on Three’s page was £24, rising to £27.50 from 1 April 2027.
Here’s our own rough sum, which isn’t a figure from Three. If you joined around now, you’d pay the starting price for roughly six months, the first rise for twelve months, and the second rise for the last six or so.
On the reported £15 plan, that comes to around £444 over the term, or roughly £18.50 a month on average. On the £18 plan listed on Three’s page, it’s around £516, or roughly £21.50 a month. Both assume you pay by Direct Debit. Your own total will depend on your start date and the final terms you’re offered.
What do you get with Three home broadband?
Three home broadband runs over the mobile network, so there’s no landline and no engineer visit. Three’s page says you plug the hub in and go, with next working day delivery on orders placed before 8pm.
Three says the plans run on what it calls the Nation’s Network, the combined Vodafone and Three network. Its page says unlimited data applies on the 12 and 24 month plans, so check what a shorter or rolling option includes if you’re tempted by one.
It quotes average download speeds of 150Mbps. That is not a promise about your address. Three’s footnote says the figure applies to at least half of its 5G customers in 5G coverage areas during peak hours, which it defines as 8pm to 10pm, and that individual speeds are not guaranteed and can vary.
Three’s page also offers up to £300 of credit towards switching. The conditions are on Three’s own page: it is for a new 24 month home broadband plan, it is for new or existing customers adding new lines only, and you have to email your final bill from your previous UK provider within 90 days of activating. Read those before you count on the money.
Three says there’s no setup fee and a 30 day money back guarantee. If you do order, use that window properly. Test Three home broadband in the evening, when everyone in the street is online, and on every device that matters to you, not just once on a quiet Tuesday morning.
It’s a good fit for some homes, especially where fixed line options are slow or unavailable. It isn’t the right answer everywhere. Our guide to 5G home broadband versus fibre sets out where each tends to win, and our look at what a recent study says about 5G home broadband adds some independent speed data.
What should you check before you sign up for Three home broadband?
Check the coverage at your address first. Mobile based broadband depends on the signal where you live, so use Three’s coverage checker and our guide to 5G broadband coverage before you order.
Then check how you’ll be paying, because the price you’ve been quoted probably assumes a Direct Debit. Confirm the monthly figure for the payment method you actually intend to use.
Then look at the rises. Ofcom banned price rises linked to inflation in new contracts from January 2025, and says any rise set out in a contract must be shown clearly in pounds and pence, with the dates, before you sign up. You can read the details on Ofcom’s price rises page.
So the April 2027 and April 2028 figures should be easy to find. If they aren’t clear on your order, ask before you commit. Our guide to broadband mid-contract price rises explains your options if a provider changes the price in ways the contract didn’t say.
Ofcom also points out that providers often increase the main monthly price when a contract ends. So a deal that looks sharp for 24 months can quietly turn into a pricey rolling plan if you forget about it. Three home broadband is no different from any other provider on that front.
Finally, think about the term. A 12 month plan costs more each month but leaves you with fewer rises to work through, and you can compare it against other deals when it ends. Doing nothing when a deal finishes is usually the expensive choice, so put the end date in your diary.
