What is HIES?

The Home Insulation & Energy Systems Contractors Scheme (HIES) is a Consumer Protection organisation. HIES ensures that consumers are dealt with professionally, courteously and sympathetically. Any products installed by HIES Members must be fit for purpose, installed professionally and come with comprehensive guarantees which are underwritten with specialist insurance providing consumers with a high level of protection and peace of mind.

HIES also believes that consumers should have FREE access to robust dispute resolution and therefore provide consumers with free mediation, FREE Independent Inspections to assist with installation or product malfunctions (at HIES discretion) and FREE access to an independent Ombudsman service to help resolve any issue that may arise.

To that end, The HIES Scheme Rules & Code of Practice is a stringent set of Rules and a ‘Modus Operandi’ that members must adhere to at all times in their dealings with consumers, our Code is approved by The Chartered Trading Standards Institute.
