How to get the most from referral codes
Referral codes are one of the easiest ways to save money when signing up for a new service. Every company on this page runs an official refer-a-friend programme that rewards both the new customer and the person who referred them.
The key principle is simple: only use a referral code for a service you were already planning to use. Switching energy supplier? Use an Octopus or E.ON referral for £50 off your bill. Opening a new bank account? Use the Monzo referral for up to £100 cash. The referral reward should be a bonus on top of a decision you have already made, not the reason for the decision itself.
We update this page regularly to keep the rewards, requirements, and Trustpilot scores accurate. If you notice anything out of date, let us know.
Referral code FAQ
What is a referral code?
A referral code (or referral link) is a unique URL shared by an existing customer of a company. When a new customer signs up using that link, both the referrer and the new customer receive a reward, typically cash, bill credit, points, or a gift card. Read our complete guide at referralplug.co.uk/what-is-a-referral-code.
Read our complete guide to referral codes →Are referral codes free to use?
Yes. Using a referral code costs you nothing. You simply sign up through the referral link instead of going directly to the company's website. The reward is funded by the company as a customer acquisition cost.
How do I know if a referral code is legitimate?
All referral codes on Referral Plug are genuine refer-a-friend links from real customers. Each company listed here has an official referral programme. You can verify this by checking the company's own website for their refer-a-friend terms.
What are the best UK referral codes in 2026?
The highest-value UK referral codes in 2026 include Octopus Energy (£50 bill credit), E.ON Next (£50 bill credit), Monzo (up to £100 cash), Motorway (£50 Amazon gift card), and Tide (£50 business account credit). The best one for you depends on which services you actually need.
Can I use multiple referral codes?
You can use one referral code per company (for your initial sign-up). However, you can use referral codes from different companies; for example, switching energy with an Octopus referral and opening a bank account with a Monzo referral.
Do referral rewards expire?
Referral programmes can change or end at any time. The rewards listed on this page are current as of the date shown, but always check the company's terms before signing up. We update this page regularly to keep it accurate.
Do I need to be a UK resident?
Most referral codes on this page are for UK-based services and require a UK address, bank account, or phone number. Some services like Bitrefill and Ledger work internationally.
How much can I earn from referral codes?
If you used every referral code on this page, you could earn over £500 in combined rewards. In practice, you should only sign up for services you genuinely need; the referral reward should be a bonus, not the reason for switching.
