Our verdict

PLAN-B NET ZERO ENERGY sells renewable electricity in Germany, with renewable content of 100% that suits households shopping on green credentials rather than tariff breadth. The trade-off is a short menu: tariff types run fixed, dynamic and green, fuel is electricity, and a smart meter is required before any plan starts.

Pros and cons

Pros

  • Renewable content of 100% is the headline number here, with a green tariff sitting in the list alongside fixed and dynamic.
  • Tariff types run fixed, dynamic and green, so a fixed rate and a market-linked rate come from the same supplier.
  • Fixed terms of 12 and 24 let a household choose how long it wants to hold the rate.
  • Support runs on email and help centre, giving a written route for billing and tariff questions.

Cons

  • Supply is listed for DE only, so households elsewhere cannot take out a plan.
  • A smart meter is required on every plan, so the meter has to be sorted out before supply can start.
  • Support runs on email and help centre only, so anyone who prefers to speak to a person has fewer routes in.
  • Tariff types are limited to fixed, dynamic and green, while Electricity Ratings covers fixed, ev and time of use.

Who it suits

  • Households in DE that put renewable content ahead of tariff choice and can meet the smart meter requirement.
  • Shoppers who want a fixed commitment and a dynamic option from the same supplier, since tariff types cover fixed, dynamic and green.
  • Readers happy to deal in writing, since support runs on email and help centre.

Who should look elsewhere

  • EV and prepay shoppers should try Electricity Ratings, whose tariff types include fixed, ev and time of use.
  • Anyone after a variable rate should compare Powerpeers, which lists dynamic, fixed and variable.
  • Households wanting time-of-use pricing should look at Endesa, which offers fixed, time of use and ev.

Core features

Renewable content is the headline figure, at 100%, and that is the number to weigh against any other green supplier you are comparing. The condition attached to it is hardware rather than paperwork: a smart meter is required, and supply cannot start until a meter is fitted or already in place. That is a short step in a new build and a longer job in an older property, so check the meter situation before you compare tariffs.

The company behind it

The contract would be with PLAN-B NET ZERO ENERGY GmbH, a company registered in Switzerland, while the plans on sale cover DE. The entity sits outside the market it sells into, so check your address against the listed market before signing rather than assuming coverage. Support runs on email and help centre, which means questions are answered in writing and the help centre deals with the routine ones, and in-person counters are not among those routes.

Frequently asked questions

How renewable is the electricity?+

Renewable content is listed at 100%, and that is the figure to set beside any other green supplier on your shortlist. It is given as the headline for the company rather than as an add-on to a single plan. Terms and tariff types still vary between suppliers, so weigh those separately from the green claim.

How long are the fixed terms?+

Fixed terms run 12 and 24, giving a choice of a shorter or a longer commitment. Shorter terms suit a move you already know is coming, while longer ones suit staying put and holding a rate. The tariff types list, fixed, dynamic and green, also includes dynamic and green options, so a fixed term is not the only way in.

What kinds of tariff are on offer?+

The list covers fixed, dynamic and green. A fixed tariff holds its rate for the term, a dynamic tariff follows the market, and the green option is the renewable-branded version of the same supply. Compare the shapes rather than the headline rate alone, because how a rate behaves after you sign drives what you pay later.

Where can I sign up?+

Plans are listed for DE, and the company behind them is registered in Switzerland. That means the entity on your contract is not based in the market it is selling into, which is normal for cross-border supply but still worth a check: make sure your address sits inside the listed market before you apply.

Do I need a smart meter?+

A smart meter is required, and it has to be fitted or already in place before supply begins. That applies across the plans on offer, which cover electricity only, so the requirement sits across the whole list. If your property has no meter yet, arrange that before you sign, since a plan cannot run without it.

Who is the supplier on my contract?+

The contract would be with PLAN-B NET ZERO ENERGY GmbH, a company registered in Switzerland. That legal name is what to check before signing, since a trading name and a contracting entity do not always match. It is also the name to quote if a billing query turns into something more formal.

How do I get help once I am a customer?+

Support runs on email and help centre, so email handles anything specific and the help centre covers routine billing and tariff questions. Phone lines are not among email and help centre, which means a written reply rather than a live conversation, so allow a little extra time for anything urgent.

How does the tariff list compare with other suppliers?+

Tariff types here are fixed, dynamic and green, against fixed, ev and time of use at Electricity Ratings and dynamic, fixed and variable at Powerpeers. If an EV or prepay tariff is what you are after, the wider lists are worth a look. The clearest gap is the variable rate, which appears in the Powerpeers list.
