Is Intelligent Octopus Go better than E.ON Drive?

Yes, in most cases. Intelligent Octopus Go charges at 8p/kWh overnight (11:30pm–5:30am) as of October 2026. E.ON Drive's cheap rate is typically around 10–12p/kWh in the cheap window (varies by DNO region). Octopus's rate is consistently lower, and the IOG smart charging integration means the cheap window runs for the whole home — not just EV charging. For an EV owner doing 7,000 miles per year, that 2–4p/kWh difference can add up to £50–100/yr additional savings.

Is Octopus Energy cheaper than E.ON Next?

On standard variable tariffs, both are priced at or near the Ofgem price cap, so headline rates are similar. The material difference is smart tariffs: Intelligent Octopus Go at 8p/kWh overnight beats E.ON Drive's typical overnight rate of 10–12p/kWh. For heat pump owners, Cosy Octopus (saving up to £389/yr) has no equivalent from E.ON Next.

Octopus Energy vs E.ON Next 2026 – Which Is Better? (incl. E.ON Drive vs IOG)

Q: Is Octopus Energy better than E.ON Next?

For most customers in 2026, yes. Octopus Energy holds a Trustpilot Excellent 4.8★ rating versus E.ON Next's lower score, has won Which? Best Buy seven times, prices its standard tariff at or below the Ofgem cap, and offers 100% renewable electricity as standard. E.ON Next is a better-than-average big-six supplier with a reasonable Trustpilot score, but Octopus outperforms it on smart tariffs — particularly for EV owners.

Q: How do I switch from E.ON Next to Octopus Energy?

Click a referral link such as share.octopus.energy/brave-kiwi-22 and complete the switch online in around five minutes. You do not need to contact E.ON Next first — Octopus handles the switch. There is no interruption to your energy supply. If you are on an E.ON Next fixed-rate tariff, check for exit fees before switching.

Q: Does E.ON Next have a referral scheme?

E.ON Next has occasionally run refer-a-friend promotions but does not have a permanent, year-round referral scheme equivalent to Octopus's £50 each offer. Switching to Octopus via a referral link earns both you and the referrer £50 credit — a consistent and reliable offer.

Quick Verdict: Octopus Energy vs E.ON Next

E.ON Next is one of the better traditional suppliers — it has a reasonable Trustpilot score compared with the old big-six, and it was one of the few suppliers to survive the 2021–22 energy crisis without going bust. But Octopus Energy is still the better choice for most households in 2026.

The key differentiator is EV and smart tariffs. If you own an electric vehicle, the comparison between Intelligent Octopus Go (IOG) at 8p/kWh overnight and E.ON Drive’s typical rate of 10–12p/kWh is significant — that’s up to £100+ per year more in savings on IOG for a typical EV driver. For heat pump owners, Cosy Octopus saves up to £389/yr and E.ON has no direct equivalent.

On standard variable tariffs, both suppliers track the Ofgem price cap closely so the difference on headline rates is modest. Where Octopus pulls ahead is on smart tariffs, customer service, and the £50 referral credit available when you switch.

E.ON Drive vs Intelligent Octopus Go: EV Tariff Head-to-Head

This is the comparison that matters most for EV owners. Both tariffs offer a cheap overnight electricity rate for home charging — but there are meaningful differences.

Feature	Intelligent Octopus Go	E.ON Drive
Overnight cheap rate	8p/kWh (Oct 2026)	~10–12p/kWh (region dependent)
Cheap hours	11:30pm–5:30am — whole home	Varies by DNO region (typically 10pm–8am)
Smart charging required?	Yes — compatible smart charger	Yes — compatible E.ON or third-party charger
Smart scheduling	Octopus app optimises charging automatically	Manual scheduling via charger or app
Annual saving vs standard rate*	~£417/yr for 7,000 miles/yr EV	Less — higher overnight rate reduces savings
Public charging discount	8% off via Octopus Electroverse	Via E.ON Charging network

*Vs standard variable tariff. Actual savings depend on EV usage, region, and charger type.

Intelligent Octopus Go’s 8p/kWh rate is lower than E.ON Drive’s typical overnight rate. For a typical EV driver doing 7,000 miles per year (consuming around 2,100 kWh for charging), the 2–4p/kWh difference is worth £42–84/yr in additional savings — on top of the £50 referral credit when you switch. Over a two-year contract, that’s up to £220 extra in your pocket versus staying on E.ON Drive.

IOG also benefits from Octopus’s intelligent load-shifting: the Octopus app communicates with your smart charger and ensures your car charges during the cheapest periods automatically. The whole-home cheap window (not just EV charging) also means other high-draw appliances like dishwashers and washing machines benefit from the overnight rate.

Customer Service: Octopus vs E.ON Next

E.ON Next has improved significantly compared to the old E.ON — it was rebuilt as a dedicated digital supplier and has higher Trustpilot scores than most of the traditional big six. Its current rating of around 4.1–4.2★ is better than British Gas, EDF, or Scottish Power.

However, Octopus Energy’s 4.8★ Excellent from 800,000+ reviews is in a different league. Octopus’s “team” model — where small groups of agents handle your account directly — produces consistently higher satisfaction scores than traditional call-centre models. And its seven consecutive Which? Best Buy awards reflect sustained performance across billing accuracy, complaint handling, and value.

Should You Switch from E.ON Next to Octopus in 2026?

✅ On E.ON Next standard variable tariff → switch immediately, no exit fees
✅ Have an EV on E.ON Drive → switching to Octopus IOG saves more per year
✅ Have a heat pump → switch to Octopus for Cosy Octopus (no E.ON equivalent)
✅ Fixed tariff ending soon → line up your Octopus switch for the end date
⚠ Fixed tariff with large exit fee → check whether £50 credit + IOG savings outweigh the fee

If you’re currently on E.ON Drive and happy with it, the IOG rate advantage alone (8p vs 10–12p) adds up to real money over 12 months. Add the one-off £50 referral credit and the case for switching is clear for most EV owners.
