O2 Military Discount Offer

O2 offers military discounts that take up to 25% off airtime plans of 3GB or more and 15% off plans below 3GB.

O2 Offers NHS & Healthcare Savings

O2 offers NHS staff a discount on airtime plans – 25% off for plans with 3GB data or more and 15% off for plans with 1GB-2GB data – available when buying a new phone or tablet on O2 Refresh. This saving applies solely to the airtime component (data, minutes and texts), must be claimed within 28 days of starting the contract, and is not available on Pay As You Go, SIM-only contracts, non-O2 Refresh tariffs, sharer plans, Ultimate Plans, contracts bought through third parties or Apple Watch airtime plans.

O2 Price Match Promise

O2 in the UK does not have a formal price match or best price guarantee policy, meaning they won't match competitor tariffs or compare delivery prices between their website and physical stores for new contracts or upgrades. While you can discuss possible discounts with O2's retention team, please note that any concessions would be discretionary rather than guaranteed.

O2 Referral Perks: Invite & Save

If you're an existing O2 customer with an O2 phone number, simply refer a friend who makes an eligible purchase (phone, tablet, or mobile broadband with an O2 Refresh tariff and a Pay Monthly contract) directly from O2.co.uk and you'll both earn a £25 Amazon voucher. Vouchers are issued once the referred friend signs up and remains in good standing, with no limit on the number of referrals.

O2 Delivery Perks For Extra Savings

O2 delivery options let you choose free standard delivery for phones, tablets (next working day for mainland UK orders placed before midnight) and accessories or SIMs — with faster delivery for orders over ¬£40, while accessories or SIMs under ¬£40 arrive in 2-3 working days if ordered before 15:30. Premium choices include morning deliveries, Saturday or Sunday delivery at fixed prices, plus the option to click & collect from local O2 stores with same day collection available when in stock, though certain regions and remote areas have different timeframes and restrictions.

O2 Discounts For Teachers

Teachers in state schools can save 25% on airtime plans with 3GB data or more and 15% on plans offering 1GB-2GB data through O2’s O2 Open program, provided you choose an O2 Refresh tariff. Simply text "OPEN" followed by your school’s name to 61202, purchase a new device, sign up with your work email or payslip, and add the discount via the O2 Open portal within 28 days to see the discount on your second month’s bill.

O2 Click & Collect Perks

O2 offers a Click & Collect service at its UK stores, including Northern Ireland, allowing you to pick up your order conveniently by presenting a 4‐digit collection code, valid ID, or the confirmation email if someone else collects on your behalf. This free service comes with in-store assistance for device setup, ensuring a smooth and efficient experience.

O2 Trade-In, Get More Value

O2 offers several trade-in options that help you enjoy early upgrades while cutting costs. You can use the O2 Refresh Program to pay off your device plan early with funds from O2 Recycle, benefit from lower monthly bills once the device is paid off, or try O2 Switch Up to swap to a new phone every 90 days—with O2 supporting the current contract—and even trade in your old device for cash at times when extra incentives are on offer.

O2 Returns: Clear And Hassle-Free Info

O2 offers a standard 14-day "change your mind" return period for most items, with a 30-day period for any faulty devices or accessories. Items must be returned in brand new condition with all original packaging and accessories, and can be returned in-store or by post (free return labels provided, with optional Special Delivery for added insurance), while refunds are processed within 28 days.

How to Use O2 Discount Codes
