Based out of their headquarters in Swindon, England – RWE Npower PLC is a dominant force in the UK gas and electricity market, being considered one of the Big Six energy suppliers.

Npower currently has an estimated 6.5 million customers, split across both business and domestic residences.

Employing around 11,000 people, the company was only founded at the turn of the millennium, trading as Innogy until 2002 – until the business was renamed following an acquisition by German energy giant RWE. Unlike some of its competitors – namely British Gas, E.ON and EDF Energy – it hasn’t diversified away from simply providing gas and electricity, and appears committed to that arm of its business.

Although Npower has made steps towards embracing renewable and green energy sources, the vast majority of its power comes from power plants that are dependent on coal, oil and gas. Currently, they have 9 energy stations situated across the UK, many of which provide power to the national grid as well as powering the homes of customers.

While complaints regarding unexpectedly high bills and poor service are quite regular for any energy company, Npower were the subject of calls for a public boycott in 2013, as campaign group 38 Degrees argued that they have been guilty of tax avoidance – the company vigorously denied these claims.
