Highly Recommend, great team

From initial contact to the end result we would highly recommend Tre Energy. Everything was explained in great detail, from Henry at initial contact and even more so by Thomas on installation day we couldn't fault the team - their customer service is next to none. Not to mention we are now saving on our electric bills. Great all round

Great service from TRE Energy

TRE Energy recently installed our solar panels and battery system. From quote to installation, it was seamless. All members of TRE were a pleasure to work with, professional, efficient & accommodating. We are delighted with the results and would highly recommend. Thank you!

Used TRE on recommendation of a friend. What a breath of fresh air! Great communication and flexible to fit with my requirements. No hard sell , just great people to deal with.

Amazing results from the Solar panels…

Amazing results from the Solar panels installed on our domestic property. Our home was running on approx £3 per day on electric which has been reduced to as little as 6p per day with the solar panels, whilst also earning money back selling it back to the grid. Great customer service from start to finish and would highly recommend installation from this company on domestic dwellings to slash your electric bills.

I wanted a quality ground based solar array

I wanted a ground based array that could easily withstand stormy weather. Without a doubt the quality of the set up delivered by Treenergy was the best across the companies I talked too. The system was installed quickly and the staff were all super professional. Would highly reconditioned this company for ground based solar installations.

Great company Great customer service

We approached this company for some information guidance and a price they were very informative and quick to respond to any requests made. As our company had to wait for funding applications etc we kept TRE waiting but no matter when I contacted they were straight back to me answering any queries. Once installation had began it was very quick the panels were up in no time. All customer service was very pleasant and very quick at getting back to me if I had anything to ask after. So far everything to do with the panels has been smooth.

TRE fitted our solar system

TRE fitted our solar system and battery storage for a very competitive price for our home. They completed all the paperwork and we have been up and running around 6 months at this stage and it is a great system and has greatly reduced our bills. The work carried out was excellent and very tidy install. The men couldn’t have been any better and they were so tidy and cleaned up and you would not know they had been here. Highly recommended company!!!

I would highly recommend Tre Energy

I had contacted four solar panel installation companies and Tre Energy Ltd response and presentation was streets ahead of the others. I went to see one of their recent installations at a friends house before signing up. I am very fussy that a job is done right and the electricians and panel installers were really great. Panels, battery, eddi and inverter were installed in a day and a half. Electricians excelled and overcame a cable routing challenge better than I expected. I would highly recommend Tre Energy.

Purchased panels and battery system…

Purchased panels and battery system from Tre energy. All seemed great at the outset at sales stage. Sadly since installation, there have been a few issues and atrocious customer service. On average it takes at least 6 weeks for a response despite repeatedly ringing and emailing. We have been asked if we would recommend this company and sadly we cannot as their after service is extremely poor. Currently we are still awaiting a response despite an 2nd alarm on the system 7 weeks ago asking for the matter to be addressed asap; this is the second time this alarm has raised and no-one has been in contact. There have been other issues with panels not working and this also took many weeks to resolve.

Hi Alan, I have flagged your account with Trustpilot. We have never done work for you and its highly unprofessional to make up a fake review that could damage our professionalism and credibility.

Rated 5 out of 5 stars

Efficient and Professional Company

We had solar installed by TRE over 6 months ago. After an initial enquiry they sent out a representative to survey the property, make recommendations and provide a quotation. Of the 3 companies I contacted for a quotation they were the only one to send someone out. At the time I booked the installation there was quite a waiting list so it was a few months before the work was done. Work was completed very efficiently in a few days. All staff were helpful, courteous and professional. I can’t comment on the after sales follow up as everything has worked perfectly since installation.
I am delighted by the installation - it has made a big difference to our electricity bill! I also love the Myenergi app which tracks our usage.
All told, I can highly recommend this company.
