I want to upgrade as often as possible, how can I do that?
Addicted to the latest releases? You need O2 Refresh, which lets you change plans and phones whenever. By handling the phone and plan separately, you’re free to keep the contract you like and upgrade the phone as often as you want. You’ll need to pay off the Device Plan for early upgrades but you won’t need to pay anything for your new phone upfront.
How long has VoucherCodes worked with O2?
We've partnered with O2 to provide legitimate codes since 2008.
- Discounts
Can I use more than one O2 discount code?
You’ll see frequent money-saving O2 deals including NHS discounts, O2 student discounts and money off selected products. However, you can only use one O2 discount code at a time, you can’t stack them.
Can I use an O2 promo code on sale items?
Generally, if an item or contract at O2 has already been discounted, you won’t be able to get a further discount on top of that. O2 discount codes are usually to be used on full-priced products.
Does O2 offer an NHS discount?
If you work for the NHS, you may be able to get a discount at O2. If your company or organisation is registered for O2 Open then you could save money when you sign up or upgrade to a new O2 Refresh plan. Scan all the latest NHS discounts with O2 to find out more.
What kind of saving can I make with O2?
Our data shows that VoucherCodes users save around £16 when using an O2 discount code. This amount could be more or less depending on the codes available and how much you spend.
Buyers Guides
How to save at O2
If you’re looking for strong coverage, generous roaming allowances, and useful perks, it could be time to switch to O2. There are lots of ways to save money on your next phone or contract, including these money-saving tips. Don’t forget to scroll through our O2 discount codes too!
1. Sign up for O2 rewards:
Earn rewards equalling 5% of your top-up every quarter on pay-as-you-go when you sign up for O2 rewards. You’ll get other perks too, including discounts and gifts, so it’s well worth subscribing.
2. Get a Multisave discount:
Add a new Pay Monthly connection to your account and get 20% off the airtime. Find out more on the O2 website. This could be a great idea if you’re setting up an account for your teen.
3. Look out for special deals at O2:
Check out the O2 homepage for the latest special offers. You can often get discounts on selected handsets, such as free 12 months airtime, or low monthly rates.
4. Consider a SIM-only deal with O2:
You may find that going for a SIM-only contract works out cheaper than a full Pay Monthly plan. Check out the deals on offer at O2 and see how much you could save. This is great if you’re on a budget or if you don’t want to finance a new device.
5. O2 Open:
You can get up to 25% off your Airtime Plan when you buy a tablet or phone on O2 Refresh, with their employee discount programme O2 Open. To qualify, you’ll need to work with an eligible company, and they are already working with the NHS, teachers, Sainsbury’s and more. So, head online to find out if your employer is part of the programme.

We check the validity of our O2 codes daily and update them weekly. The in-house content team is always looking for extra O2 deals to run alongside our exclusive offers to give you as much choice as possible.
