Npower

Npower is a United Kingdom‑based energy supplier that provides electricity and natural gas to residential and business customers. The company offers a range of tariff options, including fixed‑rate, variable‑rate and green energy plans sourced from renewable generation. It serves households and organisations across England, Scotland and Wales, delivering energy through the national grid and gas network.

Among the United Kingdom’s larger energy retailers, Npower has positioned itself as a participant in the so‑called Big Six group of suppliers. It has emphasised renewable energy offerings, providing customers with the option to source power from wind, solar and other low‑carbon sources. Npower has also taken part in government‑backed initiatives such as the Warm Home Discount scheme and has contributed to the nationwide rollout of smart meters, aiming to improve energy efficiency and billing accuracy for its users. The firm maintains customer service channels that include online account management, telephone support and mobile app access, although the app was temporarily suspended following a 2021 credential‑stuffing incident.

In terms of ownership, Npower’s retail business was acquired by the German utility E.ON SE in 2019, after which the brand continued to operate as part of E.ON’s UK operations. This integration placed Npower within a larger European energy group while preserving its distinct market presence in Britain. The company’s headquarters remain located in the United Kingdom, reflecting its continued focus on serving domestic consumers and enterprises within the region.
