How to claim your £40 back from Three UK

Six steps. One referral link. £40 lands after Three UK confirms your first bill has cleared. Last checked 2 September 2026 – the offer is live.

The six-step claim journey

Every step matters. Miss one – most commonly step 3 – and Three UK rejects the referral. Follow this order exactly and the £40 lands on schedule.


1. Click my referral link

Open aklam.io/fCrfBuXl in a fresh browser tab. That single click opens the referral tracking session – it has to happen before you land on three.co.uk. Don’t skip this and go direct.

2. Pick your plan on three.co.uk

You’ll land on Three UK’s site with the tracker attached. Choose a qualifying plan – a Pay Monthly phone contract, Home Broadband, or SIM-Only. Pay As You Go and Business plans aren’t eligible. Fill in your personal details as normal.

3. Don’t visit any cashback or voucher site after clicking

This is the one that catches people out. Once you’ve clicked my link, do not open TopCashback, Quidco, MoneySavingExpert, or any voucher/comparison site before finishing your Three checkout. Their cookies overwrite our referral tracker and the £40 gets rejected.

4. Finish checkout in one browser session

Complete the whole order without closing the tab or switching devices. Keep cookies enabled. If you have to pause, leave the tab open – closing it can break the tracking.

5. Get your Three plan activated and wait for the first bill

Once your SIM arrives or your service activates, use the plan normally. Your first Three bill drops around 30 days later. The paid-first-bill event is the confirmation trigger – that’s what starts your reward clock.

6. Withdraw the £40

You’ll get an email when the reward is ready to claim – typically 3 to 8 weeks after your Three activation. Log in to your rewards account, find the Three UK transaction, and hit Withdraw. Money hits your bank or PayPal within a few working days.

Four mistakes that get cashback rejected

  1. Opening a cashback site after clicking the link. TopCashback, Quidco, and any voucher/comparison site will overwrite our referral cookie. If you want a cashback-site payout instead, pick one – don’t try to stack. The £40 here is usually higher.
  2. Being an existing Three customer. If you’ve held a Three contract in the last 12 months, you’re not eligible. This includes PAYG accounts you may have forgotten about.
  3. Cancelling in the 14-day cooling-off window. Three lets you cancel free within 14 days. If you do, the £40 is voided – you can’t cancel and still claim.
  4. Signing up to Pay As You Go or a Business plan. Only Pay Monthly Phone (24-month), Home Broadband (rolling), and SIM-Only qualify. Business and PAYG are excluded from the referral programme.

If something goes wrong

The link doesn’t redirect. Clear your browser cache and cookies, then try again in a fresh Incognito / Private window. If it still fails, drop me a message and I’ll send you a fresh one.

The reward shows as “Rejected”. Usually means a voucher/cashback site was opened after clicking the link, cookies were cleared mid-checkout, or the Three account got cancelled within the 14-day window. You can appeal via the rewards platform’s Help Centre if you have proof – see the audit-trail tip below.

No confirmation email after 8 weeks. Log into the rewards platform directly and search for your Three UK order number. If it’s not showing, contact support with your Three order confirmation email – most delays are just their queue.

Withdrawal failed or the money hasn’t arrived. Double-check that the bank or PayPal details on the payout match the name and address on your Three UK account. Mismatches trigger anti-fraud holds.

💡 My audit-trail tip

Screenshot the referral confirmation page right after you click the link, and save your Three welcome email plus order-number confirmation. Those three pieces of evidence are all the rewards platform needs to overturn a rejected claim if it happens.
