What Our Customer Says

James Patterson
Excellent Service from Start to Finish!

Eco Spark Energy made the whole process effortless. They checked my eligibility, handled all the paperwork, and within days, I had a brand-new boiler installed completely free of charge. The engineers were professional, tidy, and explained everything clearly. Highly recommended!

Lisa Bennett
Great Service, Small Delay in Installation

The team at Eco Spark Energy was fantastic—very helpful and professional. The only reason for 4 stars instead of 5 is that my installation was delayed by a few days due to high demand. Other than that, everything was smooth, and I now have a fully working, free boiler!

Sarah Davies
Totally Free and Hassle-Free!

I couldn’t believe it when they told me I could get a free boiler installation—but it was true! No hidden fees, no catches, just a brand-new, energy-efficient boiler. The team was friendly and kept me updated throughout. My home is now so much warmer, and I’m already noticing the savings!

Michael Harris
Excellent Boiler, Minor Communication Issues

The whole process was seamless, and the boiler works perfectly! The only thing that could be improved is clearer communication—I had to chase up my installation date. But once they arrived, the engineers did a great job!

David Richardson
Fast, Professional, and Reliable

From my first enquiry to installation, Eco Spark Energy was amazing. The whole process took less than two weeks, and the engineers were punctual, knowledgeable, and efficient. I didn’t have to do anything—just sit back and enjoy my warm home. Thank you!

Rebecca Wilson
Really Pleased – Just Wish I Knew About This Sooner!

Eco Spark Energy made everything so easy, and my new boiler was installed for free. I just wish I had known about this scheme sooner! The only slight issue was a small delay in responding to my initial enquiry, but otherwise, excellent service.

Emma Johnson
Huge Savings and Great Customer Service

My energy bills were sky-high, and my old boiler kept breaking down. Eco Spark Energy replaced it completely free, and now I have an energy-efficient model that works perfectly. The whole team was polite, helpful, and really knew their stuff. Would highly recommend!

Tom Carter
Good Experience but Could Be a Bit Quicker

The service was great, and the installation was done professionally. However, the process from enquiry to installation took about three weeks, which was a little longer than expected. Still, the fact that it’s completely free makes it well worth the wait!

Mark Thompson
Life-Changing Upgrade!

I never thought I’d qualify for a free boiler, but Eco Spark Energy made it happen! The installation was smooth, and the engineers were respectful of my home. It’s made a huge difference in heating my house properly, and I’m thrilled with the service.

Charlotte Evans
Very Happy, Just a Bit of Mess to Clean Up

I’m really happy with my new boiler, and the installation was quick and efficient. The engineers were great, but there was a little bit of dust and mess left behind that I had to clean up. Not a big issue, but worth mentioning. Otherwise, brilliant service!
