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

Thank you so much for taking the time to share your experience. We’re delighted to hear that every part of the installation team from scaffolding through to electrical and plumbing made such a positive impression.

It’s fantastic to hear Kai, Ritchie, Ed and Declan stood out during the project, and we’ll be sure to pass your comments on to them and the subcontractors involved. They’ll be very pleased to know their hard work and professionalism were appreciated.

We’re really pleased the installation was completed on time and that you found the team friendly, polite and respectful throughout.

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.

Good results but very poor communication

Communication is certainly not this company’s strong point - finished the job in April, waited another 6 weeks with workers turning up with no ladders and other equipment to finish solar installation and still waiting on a window to be replaced that they broke during installation - email after email asking for the same information and still no results but the work is done, not on time but with reasonable results and companies that completed jobs courteous and polite taking care in the property - just need to get their act together and sort out who is talking to who and sorting things out for customers in days not months

The team turned up early and worked flat out for two days, unusual these days.
They were so tidy, professional and organised it was a pleasure having them at our home.
An explanation of what had been done to finish off was given by the team leader.
Excellent job.

Smashing workers.

The men were polite & worked well. They cleaned up as they worked & left nothing out of place.
The work went on longer than expected but this happens.

The A teams

The air source heat pump team, with team leader Richard, did an excellent job for me. They were clean,tidy, respectfull and efficient.
The solar panels installation with Michael Maclean and son Jack. Did a wonderful job.
I am grateful to Union Technical and the people mention above. This work has made my life more comfortable. It was a pleasure to have them working here. I would highly recommend them to anyone thinking of having this work carried out. Thank you all.
