HIES Reviews 

Yes the understanding about the product and good communication on there part would recommend this

DomElec are a company that's put's the customer first being polite and friendly from their office staff and also the installation team, great job thanks.

Installation performed very quickly, to the highest standard, by highly qualified technicians. We highly recommend Titan Energy Solution.

Great communication, professional and genuinely helpful

Mark thoroughly explained the whole process which made it easier to make the decision… I took my time.

Installation was as promised and there were no glitches.

All staff very professional.

I was particularly impressed by how smoothly the whole process went and ultimately how quickly the team took out my old system and got the new one running. I was never for one day without hot water. And it was very thoughtful indeed to provide me with heaters for the few days of no heat. The professionalism of the team was incredibly tidy and at the end of each day my home was made tidy and ready for the next day. They kept me informed throughout the process so I always knew what the next stage was. It made the transition much easier from day to day. Where possible they found solutions to hiding pipe work for which I am very grateful.
It’s a relief to have a reliable heating and water system without the regular breakdown of my old boiler. I can certainly recommend Global to anyone thinking of a new heat pump system. The process took 4 days to complete and 1 day to commission it and it was a pleasure to have them in my home.

Totally impressed with the company that installed the heat pump.

Great team, very happy with their install.
John was very good, explain well, quote was accurate from the start. Discussed several options together.
Result is outstanding

Reassuring to have HIES vetting contractors before investing large sums of money. I’ve had no issues with my installer but it’s good to know I have support if needed

All staff were very polite and went above our expectations in ensuring that there was very little damage to existing flooring. They made sure that their equipment was stored tidily throughout the fitting and ensured that we were happy with their installation and positioning of radiators, etc.

I was fully satisfied from start to finish. The salesperson was very informative and the installation went very smoothly. I would definitely recommend this Company.

Every thing was explained as to what was happening and the tradesmen were absolutely top notch

I had solar panels and a Tesla 3 storage battery lfitted by Octopus Energy and the whole purchase and installation went so smoothly and easy. The installation team were excellent keeping us up to date with the installation progress. The installation took two days and the team were very tidy.

Every stage of the project that was expected to be done was exactly on time. And went like clockwork. Materials that was used are of a high quality. Workers just new what they were doing and made such a great job.
Could not fault the anything, and we are delighted with the results.
Well done!

Excellent service, kept me up to date with the solar installation and they vetted my installer.i didnt realise but they protect the deposit along with insuring the installer's guarantee is valid

It's really good to know that our solar system has protection and that HIES is on hand should any unforeseen issues or problems arise. I would urge ensuring that companies are registered with HIES before committing to installing solar and or battery.

Very quick service - friendly staff - and very neat work

Very happy with the professionalism of HIES.

The experience from the sale person to the installation team and follow up after installation was a great experience, thank you
