Octopus Energy vs Utilita (2026)
Utilita is genuinely good at one specific thing — pay-as-you-go and prepayment energy — and if you want to top up rather than pay by monthly Direct Debit, it deserves a serious look. But if you pay (or are happy to pay) by Direct Debit, Octopus tends to win on independent satisfaction scores, a far wider range of smart and time-of-use tariffs, and certified 100% renewable electricity. For most households outside the prepay niche, Octopus is the stronger all-rounder — and you can pick up £50 of welcome credit on the way in.
Switching from Utilita takes ~5 working days with no break in supply — and my link gets you £50.

Utilita is genuinely good at one specific thing — pay-as-you-go and prepayment energy — and if you want to top up rather than pay by monthly Direct Debit, it deserves a serious look. But if you pay (or are happy to pay) by Direct Debit, Octopus tends to win on independent satisfaction scores, a far wider range of smart and time-of-use tariffs, and certified 100% renewable electricity. For most households outside the prepay niche, Octopus is the stronger all-rounder — and you can pick up £50 of welcome credit on the way in.
Utilita was founded in 2003 by Bill Bullen and runs from Chandler's Ford in Hampshire, and it's unusual in being built almost entirely around prepayment customers — the group is even linked to meter maker Secure Meters, which feeds its smart-meter and PAYG focus. That niche is its real strength, rather than the broad smart-tariff and Direct Debit market Octopus leads.
Where Octopus tends to win
- A much wider tariff range for non-prepay homes — Agile half-hourly pricing, Tracker daily wholesale rates, Intelligent Octopus Go for cheap overnight EV charging, Cosy Octopus for heat pumps and Outgoing Octopus for solar export, where Utilita's line-up is built around prepayment and PAYG.
- Certified 100% renewable electricity as standard, whereas Utilita supplies grid-average power (on average only around half from renewables) and doesn't sell a tariff labelled as renewable.
- A stronger independent track record: an 'Excellent' Trustpilot rating around 4.8/5 and Which? Recommended Provider many years running, versus Utilita's respectable but lower 'Great' rating around 4.2/5.
- Scale and stability as the UK's largest electricity supplier, used by roughly one in four households, plus Octoplus rewards with free monthly Wheel of Fortune spins and Saving Sessions you can earn money back from.
- A £50 welcome credit paid automatically when you join through a referral link — Utilita has no comparable joining bonus.
Where Utilita still has a case
- Utilita is the UK's leading prepayment and pay-as-you-go specialist, and unlike many suppliers it doesn't charge prepay customers a higher tariff than Direct Debit ones — a genuine plus if topping up suits your budgeting.
- The My Utilita app is well regarded and award-winning, with clear day-by-day usage tracking, the ability to move credit between gas and electricity meters, and up to £15 emergency credit if you run low.
- Its Smart Energy Prepayment tariff swaps a daily standing charge for a higher rate on your first 2kWh each day, which can work out well for lower-usage homes who hate paying a standing charge while away.

How to switch from Utilita to Octopus
Switching from Utilita to Octopus is straightforward and protected by Ofgem and the Energy Switch Guarantee, so your gas and electricity never get interrupted — it's the same pipes, wires and meter, just a different company sending the bill. Tap the referral link, pop in your address and a recent meter reading, and Octopus handles the changeover with Utilita for you; there's nothing to cancel yourself and most switches complete in about five working days. Because you joined through a referral link, £50 lands in your account automatically — no code to claim — roughly two to four weeks after your switch completes and your first monthly Direct Debit is taken (note that this works for Direct Debit accounts, so it's worth checking your preferred payment setup first). Signing up by typing Octopus's address directly or via a comparison site usually means no bonus, so use the link itself.
FAQs
How much is the Octopus Energy referral bonus?+
£50 for you and £50 for the referrer — £50 each. Business and charity referrals are £75 each. Octopus sometimes frames it as “splitting £100 with a mate”, which is the same thing: £50 into each account.
Is the Octopus referral code still working in 2026?+
Yes. The scheme is active and we re-verify our code on the 1st of every month. We last confirmed it works on 1 June 2026.
How long does it take to get the £50 credit?+
It’s paid automatically once your switch completes and your first monthly Direct Debit has been taken — usually around 4 weeks after you join. No claim needed.
Is this an official Octopus Energy offer?+
Yes — refer-a-friend is Octopus’s own scheme. Energy Referral is an independent guide, not affiliated with Octopus, but the link takes you straight to Octopus’s website where you sign up directly with them.
