A Quick Note On npower

If you’re an npower customer then you’re probably aware that npower has been taken over by EON Energy. All residential and small business clients have been moved over to EON Next. Larger businesses will still keep their contracts with npower, but under npower Business Solutions. 

However, you can still qualify for an npower free boiler because EON Energy also has a free boiler scheme, and all of their eligibility criteria are the same. 

Confused? Don’t be. At Eco Grants, we’re used to navigating the complex world of grants and schemes, and we can guide you further on how to apply for an npower free boiler through EON Energy if you need additional support.

For now, let’s take a look at what the npower/EON free boiler scheme is all about and its eligibility criteria. 

Am I Eligible For An npower Free Boiler?

The npower/EON Energy free boiler scheme doesn’t really exist in the traditional sense – rather, it’s an easy way to describe the fact that EON Energy, as one of the UK’s largest energy suppliers, is obligated by the UK government to support its most vulnerable households with making energy efficient upgrades to make their home more comfortable and affordable. They do this by offering a series of grants and schemes which could help you in securing a free or significantly cheaper boiler. 

In order to receive support from these grants and schemes, though, you’ll first need to meet the eligibility criteria. The two main schemes that will prove most relevant to you are:

  • ECO4
  • Boiler Upgrade Scheme (BUS)

ECO4 Explained

You could qualify for an npower free boiler through EON if you meet the criteria for ECO4. ECO4 is a government-led scheme that encourages energy suppliers with over 100,000 UK customers to support their most vulnerable customers living in energy inefficient homes to better manage their energy bills and enjoy a home that’s much more comfortable to live in. 

ECO4 takes a whole-house approach to making eco home improvements, meaning you could qualify for a range of measures, including upgrading an old, inefficient heating system with a new A-rated boiler instead. 

The scheme is set to run until March 2026, and is fully funded by the UK government – up to £4 billion. That means plenty of the most vulnerable low income households could still benefit from support and receive a free or much cheaper boiler. But first, you’ll need to make sure you qualify for support. 

ECO4 Eligibility Criteria

To qualify for a free boiler as an ex-npower customer with EON Energy through ECO4, you’ll need to:

  • Be an EON Energy customer (you will have moved automatically to EON Next as part of the takeover when EON bought npower)
  • Live in a home with an Energy Performance Certificate (EPC) rating of D-G
  • Own or privately rent the home
  • Be in receipt of qualifying government benefits

Boiler Upgrade Scheme Explained

The Boiler Upgrade Scheme (BUS) is another government-led initiative, and whilst its eligibility criteria is quite similar to ECO4, its approach is not. 

The BUS focuses specifically on replacing old, fossil fuel fired, inefficient boilers with more modern, greener options. However, you won’t find a more traditional combi boiler here. Instead, the scheme only funds air source and ground source heat pumps, and biomass boilers. 

It’s important to note that BUS is only a scheme for those living in England and Wales, but it’s still worth considering if you have a home that’s suitable for a biomass boiler (more on this later). 

BUS is set to run until 2028 and offers £5,000 towards the cost of a biomass boiler or air source heat pump, and £6,000 towards the cost of a ground source heat pump. 

BUS Eligibility Criteria

In order to qualify for an npower free boiler with EON via the Boiler Upgrade Scheme, you’ll need to meet the following criteria:

  • Be an EON Energy customer (you will have moved automatically to EON Next as part of the takeover when EON bought npower)
  • Have an old, inefficient boiler that runs on fossil fuels
  • Live in a home with a poor EPC rating and low energy efficiency
  • Be considered a low income household 

A Warning About Biomass Boilers

Biomass boilers aren’t suitable for every home. You’ll only qualify for support for a biomass boiler if your house isn’t connected to the gas grid and is in a rural location – which means it will apply to very few households.

As an alternative, you could opt for a ground source or an air source heat pump with BUS, or else you might qualify for support under ECO4 where you’ll be able to receive a fairly standard A-grade combi boiler which may be more suitable for your home.

npower Free Boiler FAQs:

Some people will receive an npower free boiler through EON, providing they qualify for a grant that will cover the full cost of the installation. Remember, as the customer you won’t actually have the money sent directly to you – instead this goes to your installer and will be taken off your final bill. 

If your grant covers the full cost then you won’t need to spend any money yourself, but if it doesn’t, you will need to pay the remainder of the bill.

ALL grants and schemes are aimed at supporting vulnerable households – usually classified as low income households living in energy inefficient properties. You might also be considered vulnerable if you’re struggling with debt, have health issues that may be worsened by your living conditions, or are living in an area of deprivation in the UK, for example.
