Who are npower?

npower is one of Britain’s leading energy companies, with more than 3.6 million residential and business customers across the country. It’s one of the so-called ‘Big Six’ energy suppliers with around 6.5 million people staying powered and warm thanks to their energy. That makes it the third largest provider in the UK.

Originally established as National Power back in 1990 following the privatisation of the state-owned Central Electricity Generating Board, it is now part of the E.ON group. Here’s a little recap of their history:

  • In 2000, npower was founded as part of Innogy plc and National Power. Innogy went on to buy Northern Electric, a regional electricity supplier.
  • March 2002, RWE, a German electricity company, bought npower and the companies merged.
  • In 2006, npower bought a large amount of shares from Telecom Plus, and in 2009, they bought Superior Plumbing who work in social housing across the UK.
  • 2013, npower went on to sell Telecom Plus to Utility Warehouse.
  • After dividing up the company into energy and retail services respectively, RWE now own npower as a subsidiary company. They are now called npower Limited.
  • However, the biggest acquisition took place in 2019, when Eon bought npower. After the failure of a merger between SSE and npower, Eon decided to complete the acquisition. For the time being, npower exists as part of Eon, but over the next couple of years, the full merger will be complete and npower will cease to exist independently. This will involve npower ceding all of their clientele to Eon and job cuts. In fact, new customers cannot start up on a new npower tariff, although existing plans will not be affected. New customers will be sent to Eon’s site to choose one of their tariffs.

  • Smart meters to help you keep track of the energy you are using

What support do npower offer?

Warm Home Discount Switch Plan

npower offer the Warm Home Discount to their customers who are struggling to pay their energy bills. This particular government grant swipes off £140 from your energy bill between October and February, allowing you to heat your home for less. During the winter months, energy can be more expensive because of a higher demand, so if you are having trouble paying your bill in the winter, you can check if you are eligible for this grant.

Energy Fund

As well as the Warm Home Discount, they have their own charity called the npower Energy Fund. This is a similar grant in that it aims to reduce fuel poverty by helping their customers pay their bills if they are struggling. However, given this is an npower scheme, it will no longer be available from June 2020 due to the Eon acquisition.

The ECO Scheme

The ECO Scheme is a scheme that aims to help people with home services, such as loft insulation, boiler repairs, etc. Through this scheme, people who are financially struggling can get discounted or free home services. The 11 largest energy suppliers in the UK are obliged to form part of this scheme in order to tackle fuel poverty and help people heat their homes. Because of this, npower customers will still have access to this scheme through E.on.

If npower sounds like the right supplier for you, then we can help you make the switch.
