Union Renewables Ltd

Recently had solar panels, air source heater and insulation installed. Big job, does require a fair amount of redecorating afterwards but they guys were great, answered any questions I had and the job was really well managed. Special thanks to Harrison who coordinated the project and was really efficient and chasing stuff up for me when needed, really made a the experience much less stressful having one point of contact who was coordinating it all. Appreciated the quality check once the work was completed for peace of mind and answering any final questions.

I found it was not worth the hassle of asking them for help: I was looking to improve our heating and insulation. Called them twice in July and August 2025. Told I would hear back from them. Nothing. Then, with support from Home Energy Scotland, they carried out a survey. Surveyor was great, but Union Technical didn't even follow it up. When asked about this, given nothing.

Very pleased with the professional approach Union Technical showed in all aspects of my Survey and Installation of my Air source heat pump and Solar panels just wish I got a Battery included? But very happy with the people who installed all they all made a tidy job and in a quick turnover.

This is a great company - we had several major heating upgrades done through them, including cavity wall insulation, room insulation, solar panels and a heat pump installation, and they also helped us secure the grant. They're highly professional, and I’m particularly impressed by how efficient their communication is. Whether you contact them by email or phone, they respond promptly and handle everything smoothly, and their technicians are very professional and knowledgeable. It's a company you can trust, highly recommended.

We had this company about a year ago. They came early and in the room upstairs started to throw our stuff about. And I said to the young lad about slamming the front door everytime he went in and out and he got attitude about it. We wasn't even told that the pipes was on the outside of the wall, which we will have to do something if decided to sell - looks absolute mess. He left the attic roof window open which didn't know about after a down pour of rain, also ruined an expensive carpet!!!. The system wasn't even installed correctly which took them months to come and check. We had high bills because of this. The latest the solar box in the hallway is flashing which it shouldn't and was told it needs a part etc and guess what STILL WAITING. You will notice as i phoned each time, they was waiting til after a year as they don't have anything to do with the system. I would stay clear this company as when you have problems they don't want to know!!!!.

Excellent service

The staff from start to finish were first class, resolved any issues to get the project on track. The installers were equally great, they did the whole installation with no fuss or mess, very professional service. Thank you to all the team at Union Technical

Excellent workmanship

The men who came were very informative throughout. And even hoovered once they had finished inside. Would highly recommend

From very first enquiry through the…

From very first enquiry through the process so far this company have been excellent .Office staff kept us updated all the way . Robert the surveyor was absolutely great, explained everything in a very easy to understand way. Could not have been more helpful

The person who scheduled the…

The person who scheduled the appointment deliberately lied to me to get me to agree to a survey. I specifically asked whether the solar panels were a problem because they had disqualified me in the past, and I was told Union Technical would replace them. I believed him. As soon as the surveyor arrived, he told me I would not be approved because I have solar panels. He even phoned to get confirmation. Union Technical wasted my time and the surveyor's time (though he still got paid for disrupting my day) and caused me undue stress just to get past my door, even though he knew I was not eligible. Such a letdown. Such a disappointment. So manipulative. I don't appreciate being lied to.
