Three 5G Broadband Deals November 2026

Three home broadband starts from £14/month on a 24-month contract, with no engineer, no landline and truly unlimited data. If you’re in 5G coverage, it’s one of the cheapest ways to get fast broadband in the UK and you can have it running the same day the router arrives.

The question everyone’s asking is: is it any good? The honest answer is that it depends heavily on your 5G signal strength. For some customers it’s transformative; for others it’s a frustrating experience of inconsistent speeds. This page covers what Three offers, who it works for, and the cases where you’d be better off with fixed-line fibre.

Our verdict on Three 5G broadband

Three’s home broadband proposition is straightforward: plug in a router, no engineer, no landline, no setup fee. If you’re in strong 5G coverage it can deliver speeds of 150Mbps or higher for less than most fixed-line fibre deals. If your 5G signal is weak or shared with a busy mast, speeds can drop significantly. It offers 150Mbps for just £14 a month which is cheaper than any fibre provider for that speed, but is not as consistent as full fibre.

The case for Three: At £14/month on a 24-month contract with truly unlimited data, it undercuts most fibre broadband deals on price. Setup is near instant with the router arriving next working day and plugs straight in, no waiting two weeks for an Openreach engineer. The 30-day money-back guarantee means you can test real-world speeds at home before you’re committed.

Three’s Trustpilot is highly rated at 4.6/5 stars with over 70,000 reviews, a score for the whole of Three, mobile included, which shows a clear positive consensus on Three.

The case against: Speeds on 5G wireless broadband vary in a way that fixed fibre does not. Three’s advertised 150Mbps average applies to at least 50% of customers in coverage areas at peak times meaning up to half may see less however this is also the case with full fibre. Real-world testing shows speeds ranging from around 80Mbps to 500Mbps depending on signal, hub placement and local mast congestion.

Our take: Three is a genuinely good option if you can’t get full fibre (FTTP) at your address, or if you need flexible broadband without an engineer visit. If you can get full fibre, it’s the more reliable choice for a slightly higher monthly cost.

Three’s broadband plans explained

Three offers two 5G home broadband plans, both with truly unlimited data and no setup fee:

5G Hub - 150Mbps average - £14/month (24-month contract)

The standard plan. Three states this as an average speed for at least 50% of customers in coverage areas at peak times (8pm–10pm). In practice, customers in strong 5G coverage often see significantly faster speeds; those on the fringes of coverage may see slower. The hub also supports up to 32 connected devices.

Price rises: £17.50/month from 1 April 2027, then £21/month from 1 April 2028. Both increases are fixed in pounds and pence, stated upfront at sign-up in line with Ofcom’s January 2025 rules.

5G Outdoor Hub - 150Mbps average

The outdoor hub package features a weatherproof hub designed to mount outside your home, where 5G signal is typically stronger than indoors. This is worth considering if your indoor signal is weak, but your coverage checker shows 5G is available in your area. Check the comparison table above for current pricing.

What’s included with every Three broadband plan

• Truly unlimited data - With no caps, and traffic only managed at times of exceptional congestion
• 30-day money-back guarantee - You can test real-world speeds at home before committing
• No setup fee - There are no engineer visits or installation charges
• Next-working-day delivery - If you order before 8pm and the router arrives the following working day
• No landline required - This runs entirely over Three’s mobile network
• Up to £300 bill credit switch offer - If you’re mid-contract with your current provider, Three will credit up to £300 to your Three account toward your exit fee when you switch to a new 24-month plan. Simply send your final bill to Three from 14 days and within 90 days of activation. New customers and existing customers adding a new line only.

How Three 5G broadband works

Three’s home broadband uses the same 5G (and 4G) mobile network as its SIM cards. There’s no physical cable running to your home, instead, a router receives a mobile signal and distributes it as Wi-Fi around your property.

This is different from fixed-line broadband in a few important ways:

Speed is variable. Fixed fibre delivers consistent speeds because your connection is dedicated to your property. 5G broadband shares spectrum with other devices on the same mast. At busy times like evenings and weekends then speeds may dip. In quiet periods, or in strong coverage areas, they can be very fast. However at least 50% of customers get 150Mbps at peak times.

Coverage determines everything. You can be in a 5G coverage area on the map but still get a weak indoor signal depending on building materials, distance from the mast and local obstructions. Three’s 30-day money-back guarantee exists for exactly this reason where it’s an acknowledgement that coverage can only be tested properly once the router is in your home.

Upload speeds are similar to cable. Like Virgin Media’s HFC network, where upload is under 10% of download, Three’s 5G upload is a fraction of its download: Three estimates a maximum of 50Mbps up against 597Mbps down. Worth knowing if you do video calls, upload content, or work from home.

It falls back to 4G. If your area loses 5G coverage, the hub drops back to Three’s 4G network. Typical 4G speeds are significantly lower than 5G, with Three estimating up to 70Mbps, so this matters if you’re in a patchy coverage area however this is a back up as opposed to a primary use.

Three 5G broadband mid-contract price rises

Three applies a fixed £3.50-per-month increase every April. Unlike the inflation-linked rises that were commonplace before Ofcom’s January 2025 rule change, Three’s rises are stated clearly in pounds and pence at sign-up.

On the 24-month plan starting today:

• Until April 2027: £14/month
• From April 2027: £17.50/month
• From April 2028: £21/month

Over the full 24-month term, that adds £91 to the total cost compared to locking in the launch price.

Is Three 5G broadband good enough for working from home?

The answer is: probably yes, if you’re in solid 5G coverage but with some caveats. The easiest way to tell is to make use of Three’s 30-day money back guarantee in which you can return it free of charge if it isn’t suitable.

Video calls (Teams, Zoom) need around 3–5Mbps upload and a stable connection. On a good 5G signal, Three comfortably delivers this. The risk however is consistency where unlike fibre, speeds can vary massively based on external factors.

If your job depends on a rock-solid connection, or you regularly transfer large files, full fibre (FTTP) from a fixed-line provider is the more reliable infrastructure. If you work from home a few days a week and your 5G signal is strong, Three is a reasonable option to get good speed at a very good price.

The Outdoor Hub is worth considering for work-from-home users. Positioning the antenna outside where signal is stronger reduces the variability that causes connection issues indoors.

Three broadband vs the competition

Three vs Sky

Sky uses Openreach fibre and starts from £22/month. Sky’s speeds are more consistent because it runs over fixed lines whereas Three’s are variable. Sky has very strong numbers in Ofcom’s complaints report with just 5 complaints per 100,000 customers, however Three doesn’t feature in this as it’s not classed as a major provider. Three is cheaper, flexible and requires no engineer but Sky is a more predictable connection for most households.

Three vs Virgin Media

Virgin Media starts from £18.99/month over HFC cable with average speeds of 132Mbps and above. Virgin’s network is fixed infrastructure, so speeds are more consistent than Three’s 5G. Virgin’s customer service record is weak but its Ofcom complaint volumes are average at 6. Three is simpler to set up, cheaper and more flexible but Virgin wins on consistency and speed where available.

Three vs BT

BT Full Fibre offers typically faster speeds, strong customer service and consistent performance. For anyone who can get BT Full Fibre, it’s a more dependable choice. Three is the alternative if you want a lower monthly cost or can’t get fibre.

Three vs Vodafone 5G broadband

Vodafone also offers 5G home broadband as an alternative to fixed fibre. The products are structurally similar with key features for both being wireless router, no engineer, coverage-dependent speeds.
