Npower was established in 2002 as the consumer division of Innogy, following a takeover from RWE, a German energy company. And its history is intertwined with several other big energy suppliers.

Innogy itself was formed back in 2000 when National Power split into two separate companies - Innogy in the UK and International Power for operations across the rest of the world.

At the time, National Power had been in existence for a decade, after the Central Electricity Generating Board was split into four companies - PowerGen, National Power, National Grid, and Nuclear Electric, which would eventually become EDF Energy in the UK.

If that wasn't complicated enough, Npower was due to merge its domestic and business energy operations with SSE in 2017, but the merger fell through with both companies blaming the newly-introduced energy price caps and testing market conditions (this was just before many smaller energy suppliers started going bust).

Npower's future was finally decided when it was taken over by E.ON. This means the NPower brand is no more and the big six will ultimately become the 'big five' (unless one or more of the larger independents step in to fill the void).

Who owns nPower?

Although Npower has been around since 2002, when it was established as the consumer division of Innogy, it is now part of E.ON after the German energy giant bought it out in 2019.

Why switch to nPower

If you switched to Npower because you wanted the security a big energy supplier brings, you were probably surprised when the company was bought out by E.ON - this means you became a customer of the German energy giant.

If you're not happy being an E.ON customer, you may be able to find a more suitable supplier by running an energy price comparison with The Energy Shop. We'll instantly compare deals from across the market to find the best energy deals in your area. And we can have you switched within 21 days.

Any electricity we use is generated from a combination of different fuels such as nuclear, coal and renewable sources (wind, water and the sun). The different amounts of each fuel contributed makes up a supplier's fuel mix.
