Historical sale patterns, expected 2026 deal windows, which plans hit best value, and how to combine Three’s Black Friday discount with our £40 cashback
Three steps between clicking and cash. No forms, no phone calls, no promo code that expired last quarter.
Hit the £40 button on this page. A tracking cookie drops in the background – no forms, no personal details, just proof that the £40 should credit to you.
Pick a Pay Monthly phone, Home Broadband, or SIM plan on three.co.uk. Same price. Same handset choice. Same terms – the referral tracking doesn’t change the deal you get.
3-8 weeks after your Three contract activates (past the 14-day cooling-off), £40 credits to your rewards account. Withdraw to PayPal or UK bank. Free, no fees off the top.
Cashback is set by Three UK, not by us. Pay Monthly and Home Broadband both hit the £40 top tier. SIM Only pays £20. Pay As You Go and Three Business accounts don't qualify.
No vouchers, points, or shop credit. Your £40 arrives as pounds – sent to you via PayPal or your UK current account. Once it’s in, it’s yours to spend how you wish.
UK's fastest-growing 5G network
Three UK has invested £2bn+ in 5G, reaching 99% of the UK population. Ookla and Opensignal both rate its 5G speeds top or joint-top nationally.
Unlimited data as standard
Most Three UK Pay Monthly and SIM Only plans come with unlimited 5G data, unlimited minutes and unlimited texts — no data-cap surprises.
Go Roam in 90+ countries
Use your Three UK allowance in 90+ destinations at no extra cost - covering most of Europe, plus USA, Australia, Brazil, and more.
Cashback amounts are set by Three UK, not by us. It’s £40 for a Pay Monthly phone contract (24 months), £40 for Home Broadband (rolling monthly hubs and fixed contracts both count), and £20 for SIM Only plans (1-month or 12-month). Pay As You Go top-ups and Three Business accounts don’t qualify.
The £40 pays out 3 to 8 weeks after your Three contract activates, and only after the mandatory 14-day cooling-off period has passed. That’s the window Three uses to confirm the sign-up and release the reward. You’ll get an email notification, then you choose PayPal or UK bank transfer — both are free, no fees taken off.
To qualify you need to be a new Three UK customer — no active Three contract in the past 12 months — signing up to a Pay Monthly phone, Home Broadband, or SIM Only plan on three.co.uk. You also need to be 18+, a UK resident, and pass Three’s standard credit check for that plan. Three verifies your details against name, address, and payment info before releasing the cashback.
No. Claiming the £40 is free — no monthly fee, no minimum spend, and no separate credit check. The only credit check is Three’s own, and that’s the same one you’d hit going to three.co.uk directly. Withdrawal to PayPal or UK bank is free — no percentage is skimmed off.
Three UK runs the UK’s most-invested 5G network — £2bn+ spent since 2020, with 5G now reaching 99% of the UK population. Ookla’s 2025 Speedtest reports rank Three top or joint-top for 5G download speeds nationally, and Opensignal ranks Three as the fastest 5G download experience across most of the UK. Most Pay Monthly and SIM Only plans include unlimited 5G data at no extra cost.
Usually yes — Three’s own promo prices (upfront discounts, data boosts, free trial months) are baked into the plan itself, and the £40 cashback sits on top. What you can’t do is click through a cashback site (TopCashback, Quidco) between our link and Three’s checkout — that overwrites our referral tracking and the £40 won’t register. Go straight from our button to three.co.uk without side-trips.
Two things can go wrong. If you cancel within the 14-day cooling-off window, the cashback is voided completely — nothing pays out. If you cancel after cooling-off but before the £40 has been released, Three may claw the reward back. Once it’s paid out to your PayPal or bank account, it’s yours — Three can’t reverse it.
Same Three plans, same prices, same handset choice. Our link just adds a £40 thank-you when you sign up.
