Best Energy Referral Codes UK 2026

Energy bills remain one of the biggest household expenses in the UK. While you cannot control wholesale gas and electricity prices, you can take advantage of referral programmes offered by energy suppliers to earn account credits that directly reduce what you pay. Every successful referral puts money back on your energy account.

UK energy referral programmes typically reward both parties. When a friend switches to your energy supplier using your referral code, you both receive account credit — commonly between twenty-five and seventy-five pounds. Some suppliers offer credits for both gas and electricity referrals, effectively doubling the reward for dual-fuel customers.

Below you will find every active energy referral code in the UK. Each listing includes the credit amount, whether it applies to gas, electricity, or both, and any conditions the new customer needs to meet. If you are happy with your energy supplier, sharing your referral code is one of the simplest ways to offset rising bills.

• Direct bill reduction — Energy referral credits are applied straight to your account, reducing your next bill by the full bonus amount.
• Both parties benefit — Most UK energy referral programmes reward the existing customer and the new customer equally.
• No switching hassle for you — You earn the referral credit by staying with your current supplier and recommending them to friends.
• Cumulative savings — Refer multiple friends throughout the year and the credits stack up to meaningful annual savings.
• Uninterrupted supply — Your friend switching supplier has no impact on your gas or electricity service — supply continues seamlessly.
