UK energy supplier referral codes and switching credit 2026
Refer-a-friend credit from UK energy suppliers: EDF Energy's £50 bill credit through https://honestcodes.co.uk/go/edf-energy, £75 for referrals made by 6 October 2026, paid straight onto the energy account.
The energy referral on HonestCodes is EDF Energy's Refer a Friend. Switch a home's electricity or gas to EDF through https://honestcodes.co.uk/go/edf-energy and EDF credits £50 to the new account, raised to £75 for referrals made between 14 September and 6 October 2026. The credit lands about four weeks after the switch completes and the first payment clears, and it applies whichever EDF tariff you choose: fixed, tracker, variable or smart time-of-use. EDF pays straight onto the energy account. For comparison, on their own sites Octopus Energy pays £50 of credit each side, E.ON Next a £50 voucher each and British Gas an Amazon.co.uk gift card worth up to £50 each for a dual-fuel switch. Every figure here is read from the supplier's own refer-a-friend page and dated.

Common questions about energy referral codes
Which UK energy supplier pays the biggest referral reward in 2026?
Until 6 October 2026, EDF Energy: £75 of account credit for a new customer referred between 14 September and 6 October 2026 (£50 at the standard rate). Octopus Energy and E.ON Next pay £50 each side, and British Gas an Amazon.co.uk gift card worth up to £50 each for dual fuel. Switch to EDF through https://honestcodes.co.uk/go/edf-energy.
Is there an EDF promo code?
EDF's new-customer reward is a referral link, not a typed code: https://honestcodes.co.uk/go/edf-energy. Open it, get a quote on edfenergy.com and switch, and the £50 credit (£75 for referrals made by 6 October 2026) is matched to you automatically.
Does an energy referral affect the price I pay?
No. The referral credit comes off your bill on top of the tariff you choose, and EDF's Refer a Friend applies to its fixed, tracker, variable and time-of-use tariffs alike.
When does energy referral credit arrive?
With EDF, typically about four weeks after the new customer joins, once the switch is complete and the first payment has cleared; EDF emails both customers when it is applied. Octopus says its credit usually takes about four weeks from when the friend joins.
