Testimonials
I found the onboarding process to be straightforward; I had a lot of support from Elizabeth and Fiona. It was great to see a robust process and it’s easy to see why HIES instils consumer confidence across our industry.
The main benefit is having everything under one accreditation – deposit protection, insurance backed guarantee, and consumer code all wrapped up in one.
Being a member of HIES is a big advantage for us as it keeps everything all in one place regarding IBG's as well as our contract T&C's and consumer code regulations.
HIES have always been very helpful and keen to build a strong relationship with ourselves, being a large installer within the renewables sector.
As an installer of Solar PV and EESS systems, our experience working with HIES has been consistently positive and highly beneficial to both our operations and our customers.
Membership with HIES has also provided significant reputational benefits. Displaying the HIES logo and demonstrating compliance with recognised consumer protection standards helps distinguish us as a trustworthy installer in a competitive market.
