At Stellar Energy, we’re committed to helping households make the switch to greener, more affordable energy through the ECO4 grant scheme. We recently spoke with one of our customers, Nicola Breach from Ystradgynlais, about her transition from coal heating to a cleaner, modern system, and how it has transformed her home.
Discovering the ECO4 Grant

Nicola first heard about the grant when she was visited by one of our representatives:
“A gentleman knocked the door. He told me about the grant, and we’d only lived here about six weeks at the time, and it was just like ‘Oh, that’s perfect!’ That w
as really just something that we needed.”
Mrs Breach’s home had been running on an old coal Rayburn in the kitchen, which was not only costly and inefficient, but it was also affecting her health. Nicola explained:
“My asthma was chronic since we’d moved in here. Don’t know if it was the smoke, the dust, the coal — but oh, it was dreadful.”
So the idea of upgrading to a cleaner heating system seemed like the perfect solution.
Why Nicola Chose to Apply
Like many families in the UK, rising energy costs were a big concern. So moving away from coal and looking towards renewable energy made more financial sense:
“We wanted to make the house warmer. Also coal is really expensive, and we’d been looking into solar anyway, so it just seemed like a perfect opportunity.”
Smooth Installation & Respectful Service
When it came installing the measures, Nicola couldn’t speak highly enough of the team:
“They were fantastic, absolutely fantastic! Every step that they did, it was like, ‘Are you happy with this?’ They were so respectful of the house… they were lovely, really lovely. There was no one that was off. They were just all really friendly, helpful, but they talked you through what they were doing.”
Nicola particularly commended the installers’ conscientiousness during the process, and going above and beyond to help her in the house. For example, stripping old tricky wallpaper when replacing the radiators:
“Oh you know, it was the little things. It was just considerate things like that. They didn’t need to, but they went the extra mile. Absolutely superb. I can’t fault it.”
Cutting Energy Bills in Half
Even though the new system has only been in place for 6 weeks, Nicola has already noticed huge savings:
“We were paying just for electricity alone about £120 a month. And I think now we’re at about £60. And we haven’t even got the export tariff set up yet, so we’ll be saving even more.”
This is exactly what the ECO4 scheme is designed to do; reduce bills for households while helping the UK cut carbon emissions.
Sharing the Benefits with Friends
Nicola was so pleased with her experience that she’s already encouraged others in her community to apply:
“I’ve recommended you already to 2 people. I invited them both over to see the work after it was done. I explained about the solar panels… this is just so much better. The guys are so respectful and everything.”
Nicola’s Final Thoughts
To sum up her experience with Stellar Energy, Nicola said:
“Absolutely superb. Absolutely superb. I can’t fault it. It’s been done to a higher standard than I expected.”
We’re incredibly proud to deliver energy solutions to households like Nicola’s – a perfect example of why we do what we do! Measures that improve lives, cut costs and support a greener future. Nicola’s story is just one example of how the ECO4 grant can transform homes for the better.
