⭐⭐⭐⭐⭐ Outstanding Service

⭐⭐⭐⭐⭐ Outstanding Service – Highly Recommended!

I recently had my boiler replaced by this company, and I am extremely impressed with the entire experience. From the initial inquiry with connor who was brilliant from the offset to the final installation, everything was handled with professionalism, efficiency, and excellent communication.

The team was punctual, well-organised, and worked seamlessly to complete the installation in just one day. Their workmanship was of a very high standard, and they took great care to ensure everything was installed properly. What really stood out to me was their attention to detail—not only did they do a fantastic job with the installation, but they also cleaned up thoroughly afterward, leaving no mess behind.

Since having the new boiler installed, my home has been significantly warmer, and the heating system runs much more efficiently. It’s made a noticeable difference in both comfort and energy usage.

Overall, I had a stress-free and smooth experience with this company, and I would highly recommend their services to anyone in need of a reliable boiler installation!

Thank you for your message. However, we have not installed solar panels or an air-source heat pump for you, and we have no record of any interaction with you. It seems like this review might be a case of mistaken identity or a fake review. We suggest you double-check the details and ensure you're reaching out to the correct company. If you need help or clarification, feel free to contact us directly.

Energy bills sky high! Absolutely con!!

My folks had the solar panels and air-source heat pump installed and their energy bills have gone through the roof! £53.13 for one week alone for a retired couple in a 3 bed terraced house! One room is warm, the rest of the house is chilly. They have tried to contact their installer and no one has ever been available to speak to. Once they suggested that we should contact our own electrician. This is an absolute con in our experience.

We have not installed anything under your name or anyone else’s as part of this scheme. Thank you for your misleading review, which we have reported to Trust pilot for appropriate action.

Would 100% recommend this company

The book in date from the first message was fast, the insulation was done very quickly and efficiently. All work was completed in the same day. The old loft insulation and rubbish was taking away the next day. The team was very friendly and I'm extremely happy with my new insulation and boiler. I would 100% recommend this company to complete your work.

Fantastic service provided by ECO4

Fantastic service provided by ECO4. From first point of contact, install was booked for within 2 weeks and completed within 2 days. Install was done very quickly and cleanly- minimum mess was made and they cleaned up everything themselves, took care not to damage anything and neatened everything up. We are really pleased.

From the time of finding out from a great lady called linsey who knocked on our door and told us we could apply for free heating and solar panels because of my health. This company then came into the picture, the full process of survey, and fitting the whole package was stress less due to the professional attitude of them and the people they engaged to carry out the work. every one of them was a pleasure to meet and speak too. It was a pleasure to have these people working in our house. After a couple of days of completion we had gentlemen from the company to check everything, rectify any problems and make sure we were happy with service and product. You may think this review is BS but it is certainly not. Thank you
