Just had an assessment for solar panels and battery. The surveyor also suggested he put us down for loft insulation. So far so good. Will keep you posted.

This comany has well trained representatives for sure.
The representative presented me with identity of who he was and who he worked for. He then informed me of all the checkes had to do for the survey and that he would carry on and he had the run of the house measuring and photographing all the inside and outside the property.He was very thorough,only a few questions to ask me,could not have gone any easier. Well pleased.

I had a very frustrating experience with Union Technical and would not recommend their services based on how my case was handled.
Initially, they visited my property and advised that I would qualify for funding. They carried out an initial survey and proceeded to apply for funding through the relevant scheme, which was reportedly approved. A further technical survey was conducted in October 2025, and I was told at the time that the work would be straightforward.
After this point, communication completely broke down. I heard nothing for several months and had to repeatedly chase for updates. Each time I contacted them, I was told that “the team will call back,” but this never happened.
After months of chasing, I was eventually told that I do not qualify for funding due to my EPC rating being too high (it's an E) — despite earlier assurances to the contrary. To make matters worse, they stated they were not required to share their data or findings with me.
This entire experience has been extremely disappointing. The lack of communication, inconsistent information, and absence of accountability has caused unnecessary stress and wasted a significant amount of time. I would strongly advise others to be cautious.

Union technical put in a new heating system, ventilation and insulation on my property. I have to say the final outcome of the hearing is great and dealing with some of the sub contractors were fine but others not so great. The level of communication has been dreadful and very difficult at times. Work started in my property at the beginning of October 2025 and was just finished in the middle of march 2026 after problems caused by themselves. They have left part of my bathroom flooring unsafe and are unwilling to compensate me if I get it fixed myself. The reason for me choosing to fix myself is so it’s done quickly. I personally would avoid this company.

Hi Kay
Thank you for taking the time to leave a review and for sharing your experience.
Firstly, we are pleased to hear that you are happy with the final outcome of the heating system installation. However, we are very sorry to hear about the concerns you have raised regarding communication and the bathroom flooring following completion of the works.
After receiving your Trustpilot review we reviewed your file and contacted you directly to discuss the issue with the bathroom floor. We did offer to arrange for one of our engineers to attend and carry out the necessary repairs, with the earliest available appointment being within our standard service timeframe. Unfortunately, we understand that you chose to arrange your own joiner to carry out the work sooner as you felt this was the best option for you.
While we were unable to reimburse the cost of an independent contractor, our intention was to ensure the issue was resolved and that any remedial works carried out by our team would meet the standard expected.
We are sorry that your experience did not meet the level of service we aim to provide and we have raised the feedback internally so that it can be reviewed by the management team.
Kind regards,
Union Technical Services
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

Hi there,
Thank you for leaving such a positive review. We’re really pleased to hear that your experience has been excellent from your first enquiry right through the process so far.
Our office team will be delighted to know their updates were helpful, and we’re especially pleased to hear that Robert was able to clearly explain everything during the survey. We’ll make sure your comments are passed on to him.
Thanks again for choosing us and for taking the time to share your feedback if we can help with anything further, just let us know.
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.

Hi there,
Thank you for taking the time to leave your review, and we are very sorry to hear about the experience you’ve described. This is absolutely not the standard of service we aim to provide, and we appreciate you bringing this to our attention.
We take matters like this extremely seriously and we will be reviewing the details internally with management, including the points you’ve raised about the scheduling conversation. We appreciate how frustrating this situation must have been, and we will investigate to ensure this does not happen again.
We’re disappointed to hear that your time felt wasted and that the information provided did not match what was confirmed during the survey visit. Your feedback is important and will be used to improve how we accurately assess eligibility before booking appointments.
Thank you again for letting us know.
Excellent work
Just wanted to say from start to finish all the workmen, which there was a lot! Did an amazing job, from the scaffolders, solar panel installers, sparkies, plumbers, esp Kai, Ritchie, Ed and Declan they were amazing. To get my property completed on time those guys went over and beyond. I know some are sub contractors but all deserve bonuses! All friendly, funny, polite and respectful.
Thank you

Contractors installed solar panels
Contractors installed solar panels - efficient, tidy workmanship and returned next day to commission a no light when they finished. Now late November in Highlands and they've been working most days when there's enough light - not this week though, dark and snow.

Thank you very much for taking the time to leave this review. We’re really pleased to hear that you found our installers efficient and tidy, and that everything was completed to the standard expected. It’s great to know the commissioning visit was handled promptly the following day.
The winter weather in the Highlands can certainly be challenging at this time of year, and we appreciate your patience while the team waited for safe daylight conditions. It’s good to hear the system is now up and running and we hope you continue to see the benefit from your new solar installation.
If there’s anything you need in future, please don’t hesitate to get in touch.
Happy but also disappointed
The workmen were efficient, the whole job was done quickly and with very few issues. Unfortunately initially there was a mix up with details of start times/dates & the insulation came through into a cupboard and a couple of other places. I also recently spoke to the salesman/agent David Montgomery that came out to talk to us and put us forward for the heating and solar panels. He was great and explained everything to us in a manner that we could understand. I'm extremely disappointed to hear that he hasn't received any payment for signing us and other customers up with Union Technical.
