All HIES Accredited Installers operate under a CTSI Approved Consumer Code, meaning they are held to high standards of customer service, transparency, and consumer protection approved by the Chartered Trading Standards Institute.
HIES is also certified to ISO 9001, the internationally recognised quality management standard, demonstrating that our internal processes are independently audited to ensure consistency, efficiency, and continuous improvement across the organisation.
Why HIES Matters
Installing home energy is a big investment. You need to know your installer is qualified, your money is protected, and support is there if something goes wrong.
HIES exists to raise standards across the home energy industry. We only work with Accredited Installers to make sure homeowners are protected throughout the entire journey. Every HIES Accredited Installer is vetted, monitored, and required to follow strict rules. That means you can feel confident that your installer is operating professionally and delivering work to the standards you expect.

Financial Protection Built In:
Deposit & Stage Payment Protection
If your installer stops trading before completing the work, this cover helps arrange for the installation to be completed in line with your original contract value, taking into account any deposit already paid.
Insurance Backed Guarantee (IBG)
Protects your installation after completion in the event your installer ceases trading and is unable to honour their guarantee.
Together, these protections ensure your investment is secure — both during and after your installation.
Insurance policies are arranged through our FCA authorised insurance broker and are subject to terms and conditions. *
* Please note: You will need to make sure your installation is registered (by your installer) with HIES for this protection to be in place.
