npower – Legacy UK Energy Supplier
npower was one of the UK’s “Big Six” energy suppliers, known for offering a range of electricity and gas tariffs for homes and businesses. In 2019, it became part of E.ON UK, and by 2021, all npower customers were fully migrated to the new digital-first platform, E.ON Next.
The History of npower
npower was originally part of Innogy, which was acquired by the German utility giant RWE in 2002. Over the years, npower gained a large customer base, offering fixed-rate, variable, and prepayment tariffs across England, Scotland, and Wales. Despite its strong market presence, it faced criticism for billing errors and customer service issues in the late 2010s.
What Happened to npower?
In 2019, E.ON acquired npower as part of a major energy sector restructuring. To streamline operations and modernise customer experience, all npower accounts were transitioned to E.ON Next by 2021. npower no longer accepts new customers or offers new tariffs independently.
Key Features of npower (Legacy)
- Wide range of fixed and standard variable tariffs
- Prepayment meter options
- Business energy plans for SMEs
- UK-based customer support (with mixed reviews)
- Smart meter roll-out began before integration with E.ON
What Does the npower Transition Mean for Customers?
If you were a former npower customer, your account is now managed under the E.ON Next brand. Your tariff may have changed, but you’ll now benefit from:
- 100% renewable electricity as standard on all E.ON Next tariffs
- Faster, digital-first customer service via app, web, and social media
- Access to smart meter installations and energy tracking tools
- More competitive and simplified tariff options
npower Reviews (Before Merger)
Prior to the E.ON integration, npower had a mixed reputation. Common praise included wide tariff choice and UK-based billing support. However, customers often cited billing disputes and long call waiting times. These concerns were key reasons for the brand’s consolidation under E.ON.
