Pros and cons

Pros

  • Tariff types cover fixed, variable and ev, more variety than Endesa at fixed, time of use and ev.
  • Renewable supply runs at 100%, so the green rate matches the headline figure rather than a slice of it.
  • The dynamic tariff needs no smart meter, so no installer visit stands between a household and it.
  • Electricity and gas come from the same supplier, since fuels cover electricity and gas.
  • Support opens on email, chat and phone, putting phone and chat next to a help centre.

Cons

  • Availability is limited to DE, so households outside Germany have no route into these tariffs.
  • Fixed terms run 12 and 24, so there is no short fixed commitment for anyone who expects to move or switch quickly.
  • The renewable promise rests on certificates, which some buyers read as weaker than supplier-owned generation.
  • Support runs on email, chat and phone, with no in-person option listed for anyone who prefers face-to-face help.

Who it suits

  • Households that want the whole supply renewable, backed by certificates at 100%.
  • Drivers who want an electric vehicle tariff in the same range as a green rate.
  • Anyone who values phone and chat, since channels cover email, chat and phone.

Who should look elsewhere

  • Anyone after a prepay tariff: Electricity Ratings lists prepay among fixed, ev and time of use, which Mainova's fixed, variable and ev do not cover.
  • Shoppers who want a shorter menu: Powerpeers runs dynamic, fixed and variable, so a fixed, variable, dynamic and green set is plenty for them.
  • Households wanting only fixed, time-of-use and electric vehicle rates, which is the whole of fixed, time of use and ev at Endesa.

What it does well

Renewable power is the standout. Mainova's green supply runs at 100%, so a household that wants its electricity backed by renewables does not have to accept a partial share. The other point worth knowing is the dynamic tariff, which follows the market through the day instead of holding one rate steady. It does not ask for a smart meter, so there is no meter to book, no installer visit and nothing to schedule before switching. That matters for renters, for homes with older hardware and for anyone curious about a market-linked rate without calling an engineer first. A full renewable share and a dynamic rate that works with the meter already on the wall make the range unusually easy to enter.

Who runs it

Mainova is run by Mainova AG, a company based in Germany. Support is the part that stands out here. Channels cover email, chat and phone, so a customer can call, send email, start a quick conversation in chat or work through a help centre without dealing with a third party. Having phone and chat open at the same time is useful, since a billing query rarely needs a long conversation while a meter or connection problem often does. The trade-off is geography. Mainova AG sits in DE and the offering is built around a single national household market rather than a cross-border footprint, so readers shopping several countries at once will find their choice elsewhere.

Frequently asked questions

What does Mainova supply?+

Mainova supplies electricity and gas, so electricity and gas can sit with the same supplier for a household running both. The tariffs on offer cover fixed, variable and ev, giving a fixed rate for stability, a variable rate for people who follow the market, a dynamic rate that moves through the day, a green option, a time-of-use rate and an electric vehicle rate.

Which market does Mainova sell in?+

Mainova sells in Germany, and the company behind it is based in Germany. That makes it a supplier built for a single national market rather than one of the brands covering several. Anyone living outside that market needs a different provider, so the country line is worth checking before reading tariff details.

Which tariff types can I pick from?+

The range covers fixed, variable and ev. For context, Endesa lists fixed, time of use and ev and Powerpeers lists dynamic, fixed and variable. Mainova's set is the broadest of the three, with a dynamic rate and a green rate sitting alongside the standard fixed and variable options plus a dedicated electric vehicle tariff.

How long are the fixed terms?+

Fixed terms run 12 and 24. That is a longer initial commitment than some suppliers ask for, so it suits households with a settled usage pattern that want the rate held. Anyone expecting to move home, change supplier or shift consumption sharply may find the variable or dynamic tariff easier to carry.

Is the electricity renewable?+

Renewable supply runs at 100%, and the basis for it is certificates. A full renewable share means the green tariff matches its headline figure rather than part of it. Buyers who weigh certificates differently from a supplier's own generation may want to read that basis before choosing.

Do I need a smart meter for the dynamic tariff?+

No smart meter is required for the dynamic tariff. That removes the usual first step of booking an installer and waiting on new hardware, which is what holds many people back from a market-linked rate. A household with an existing meter simply carries on with it.

How do I reach support?+

Support runs on email, chat and phone. Having phone and chat open at once is the useful part: a billing question can start in chat, while a meter or connection problem is easier to sort on a call. The help centre covers what you would rather look up yourself, and email keeps a written record.
