As it should be….

For once, a trade association that monitors its members and reaches out to check they have performed as expected.

A worthy ‘ticket to trade’

Thank you.

UK Energi - Cannot recommend them enough

I cannot recommend UK Energi highly enough. The whole solar and battery installation process was seamless and timely. All the team are professional and they communicate well. Thank you for your work!

Should have gotten solar earlier, don't wait any longer!

From quote to installation took about a month. Other providers were giving me install dates 3 or more months ahead. The package was tailored for my residence and I have no regrets. Slight issue with the 3rd party scaffolding company not coming on various stated removal dates, nothing to do with Infinity directly. Panels are working better than expected and you'll just have to be patient to get the paperwork sorted and your MPAN/DNO resolved ( again by your provider/3rd party) so you can start exporting and getting additional revenue to offset your layout. Finally, the price at the time was great , the staff at infinity were helpful, the installers were chill and professional. I would recommend them to anyone.

HIES: An extremely professional supplier and installer

HIES are extremely professional. No nonsense salesmanship. A bespoke solution for our circumstances and budget. Supplied the products we wanted and the installation was completed quickly, without damage or mess and in the minimum timescale. the system is already saving us 99% on our electricity bills and we are intending to convert our water central heating to their electric radiator versions in stages, Sales, installers and support service staff are well trained and experienced and do a really first class job for you. Excellent warranty on products

Great deal…

I found the process and installation reasonably trouble free. Benefits day 1 on taking it closer to self sufficiency.
My only ongoing issue is obtaining a Gen2 meter to allow to sell back energy to the grid…(not directly related to the installation/providers of my solution).
Overall a good deal and on budget.
Thanks

HEIS gave piece of mind to the installation process

HEIS gave piece of mind to the installation process (and beyond), and combined with my installer, all documents and updates were received in a timely fashion giving me further confidence things were being executed properly. They seem much more useful than FENSA and organisations like that in the past where guarantees seemingly meant nothing.

HIES an unexpected bonus

When I had my heat pump installed HIES was an added bonus I had no knowledge of. In fact if they hadn’t been so proactive I probably wouldn’t have realised they were involved at all. However it became clear they’d insured my deposit and then emailed me to say that, on completion, they offered to extend that to cover the installer going bust and prompted me to contact my installer when they hadn’t received the information they required to extend that insurance. Both surprised and very happy to have them on board

Good apart from communication

The design and information about the solar panels and battery was informative. They answered all our questions in a clear way. The only problems we had were with scheduling as no one turned up on installation day and we were not contacted. Eventually rescheduled but in retrospect I wish we had kept phoning to check things were on track. We are happy now with the finished product and at least we could speak to someone on the phone.

From start to finish the installation…

From start to finish the installation was seamless with minimal disruption. The scaffolding was up and down the same day, which was really impressive.

The team were friendly, professional and respectful of our property, leaving everything neat and tidy when they finished.

A great experience all round. I'd happily recommend Advanced Eco to anyone considering solar panels.
