Our verdict

Yello suits households in DE who want electricity and gas from one supplier and like having a wide tariff list to choose from. Its range covers fixed, variable and dynamic, and a customer base of 900,000 points to a supplier that is established rather than experimental.

Pros and cons

Pros

  • electricity and gas are both covered, so gas and electricity can sit with one supplier.
  • The tariff list spans fixed, variable and dynamic, wider than the fixed, time of use and ev listed by Endesa.
  • The green tariff is listed at 100% renewable.
  • Support covers email, chat and phone rather than a single route.

Cons

  • A smart meter is required for the flexible tariff, which narrows who can take that rate.
  • Fixed terms run 12 and 24 months, so a steadier rate comes with a longer lock-in.
  • fixed, variable and dynamic does not list a prepay option, while Electricity Ratings includes it in fixed, ev and time of use.
  • The renewable claim rests on certificates rather than power the supplier generates itself.

Who it suits

  • Households in DE who want gas and electricity from one provider.
  • Shoppers who want a wide choice of tariff shapes, including the dynamic and electric vehicle options in fixed, variable and dynamic.
  • People who would rather have several routes to help, given support on email, chat and phone.

Who should look elsewhere

  • Homes without a smart meter that want a flexible rate, since a smart meter is required there.
  • Prepay shoppers: Electricity Ratings includes prepay in fixed, ev and time of use, and fixed, variable and dynamic does not.

Core features

Start with the headline number, since that is what separates Yello in a green tariff comparison: the green option is listed at 100% renewable. That is the whole mix, which is what shoppers who want a plain green claim are looking for. Two practical points sit underneath it. The flexible tariff prices power by when you use it, and a smart meter is required for it, so a household without one should weigh the fixed options instead. Scale matters for a supplier you deal with every month, and Yello reports 900,000 customers, which puts it well beyond a new entrant serving a handful of streets.

The company behind it

The contract you sign is with Yello Strom GmbH, registered in Germany. The company was founded in 1999, and that age counts in energy, where a supplier that has lived through several price cycles is a different proposition from a brand that launched recently and repriced twice. Support runs on email, chat and phone, so a meter reading question and a billing dispute can take different routes. The registered entity is a separate legal company from the brand name, which is worth knowing if a complaint ever needs to move up a level.

Frequently asked questions

Does Yello supply gas as well as electricity?+

Yes. Yello covers electricity and gas, so gas and electricity can sit with the same provider. That helps if you would rather have one billing relationship and one support contact than juggle two suppliers across the length of a fixed term.

What tariff types can I choose from?+

The range covers fixed, variable and dynamic, and fixed terms run 12 and 24 months, so you can take a shorter commitment or a longer one. Powerpeers lists dynamic, fixed and variable by comparison, a shorter set that leaves out the electric vehicle option.

How green is the green tariff?+

The green tariff is listed at 100% renewable, and the basis for that claim is certificates. Read it as the published mix for the tariff rather than a promise about the generation you see on the day you use the power.

Do I need a smart meter?+

For the flexible tariff, a smart meter is required, and the price follows the hours in which you actually use power. If your meter is not smart yet, ask about the swap before you commit to a dynamic or flexible rate, since the timing of the install matters to the saving.

How do I get help when something goes wrong?+

Support runs on email, chat and phone, so help is not limited to one route. A billing query can go to chat, a meter problem can go by phone, and a self-serve answer may already sit in the help centre.

How long has Yello been trading?+

The company was founded in 1999 and the contract is with Yello Strom GmbH, registered in Germany. A long trading record carries weight in energy, where tariff promises and support quality are hard to judge from an advert alone.

How many customers does Yello have?+

The published figure is 900,000 customers. That is a solid base, and it also means you are not switching to a supplier so small that support disappears halfway through your term.

Does Yello run outside its home market?+

Yello serves DE, so it is a single-market provider. If you need one tariff to cover addresses in more than one country, the scope here is narrower, and any address outside that market needs a different arrangement.
