Pros and cons
Octopus
Pros
- The off peak rate of £0.08 on Intelligent Octopus Go is the single number that pulls EV owners across, and the export rate of £0.12 rewards households with panels or a battery.
- Tariff choice runs wide with variable, fixed and tracker sold under one roof, so you can move between pricing shapes without changing supplier.
- A power purchase agreement is the basis for the green tariffs, with 86.4% of the electricity matched to renewable generation.
Cons
- The exit fee of £50 ranks Octopus 22 of 29 on the brands compared, so leaving early is not cheap.
- A smart meter is required, so the smart tariffs only suit homes already set up for one and the installation has to come first.
- The Outgoing plan runs a fixed term of 12 months, so the export side of the deal carries a commitment with it.
Stadtwerke Münster
Pros
- The green tariff is 100% renewable, backed by certificates.
- Tariff choice is broader than Endesa, whose list runs fixed, time of use and ev, with dynamic and variable options added here.
- Full fibre broadband to 1,000 Mbps download and 75 to 300 Mbps upload, with the entry plan priced from €37.99 a month.
Cons
- Support runs on help centre only, with no phone line or live chat listed.
- Unit rate ranks 16 of 23 on the comparison page, so unit price is the weaker part of the offer.
- A smart meter is required, which rules out households needing one installed before they can move.
Who each suits
Octopus
Who it suits
- EV drivers with a smart meter who can charge overnight rather than during working hours.
- Households ready to run washing, heating and the car on the cheaper windows of a smart tariff.
- Readers who want electricity and gas from one supplier; Octopus covers electricity and gas.
Who should look elsewhere
- Readers who want a shorter tariff choice to weigh: Powerpeers lists dynamic, fixed and variable.
- Households that pay by prepay, since electricity-ratings lists fixed, ev and time of use and includes that option.
- Anyone after a compact set of plans: Endesa lists fixed, time of use and ev and stops there.
Stadtwerke Münster
Who it suits
- Households in Münster wanting renewable electricity and full fibre from one supplier.
- People on a dynamic or time-of-use tariff who are happy to have a smart meter in place.
- Customers who prefer a long-established municipal company to the widest tariff list.
Who should look elsewhere
- Anyone after an electric vehicle tariff, since that sits in Endesa's fixed, time of use and ev and not in this range.
- Households wanting phone or chat support, since support runs on help centre only.
- Shoppers who want a longer contract than 12 and 24, or a broader dynamic and variable mix, which Powerpeers lists as dynamic, fixed and variable.

Questions about each
Octopus
What does it cost to leave an Octopus smart tariff?+
Leaving early on the smart plans costs an exit fee of £50, ranking Octopus 22 of 29 on exit fees among the brands compared. That is neither the cheapest way out nor the priciest. If you may move home during the term, add the fee to the cost of switching before you commit to the plan.
How cheap is off peak charging on an Octopus electric vehicle tariff?+
Intelligent Octopus Go charges £0.08 for off peak electricity. That is the figure that decides whether a smart electric vehicle tariff is worth it: if the car can sit on the drive overnight, the lower window compounds month after month, and charging in the busier hours works against the saving.
Stadtwerke Münster
What does electricity cost on the green tariff?+
Unit rates run €0.30 to €0.31 on the green tariff, with a standing charge of €14.97 on top. The unit rate ranks 16 of 23 on the comparison page, so the cost of the energy itself, rather than the standing charge, is where this supplier sits higher.
Does the price change when the contract renews?+
The same price holds from the opening month to the last under Same price from first to last contract month, so there is no introductory rate that later disappears. Fixed terms run 12 and 24, which is how long that price is locked for before the next decision point.
