Top Three Vouchers for March 2026

Simple Ways to Save at Three

You don't need to be a deal-hunting expert to save money at Three. Start by always checking for a discount before you buy. A great first step is to look for a promo code on our website to apply at checkout. Next, see if you qualify for any special plans. Three offers discounts for students, NHS workers, and emergency service staff, so it's worth asking about. Finally, consider buying your phone upfront or with a lower-cost plan to avoid expensive monthly device payments.

Best Times to Shop

Timing your purchase can lead to big savings. The best times to shop at Three are during major sales events. Look out for their Black Friday and January sales, where you can find great deals on phones and plans. New phone models often launch in the autumn, so that's a good time to find discounts on older models. Also, keep an eye on their website around bank holidays, as they sometimes run special promotions then.

Using Their Rewards Program

Three's loyalty program is called Three+, and it's a simple way to get more for your money. You get access to it just for being a Three customer. The key is to check the Three+ app or website regularly.
