“With HIES you get accredited installers, independently backed guarantees (even if the firm refuses to help you or goes out of business), free access to industry inspectors at HEIS discretion, professional mediators and – if you’re unsatisfied – a highly regarded Ombudsman service who can settle your dispute with the power of the law behind them. There are lots of confusing trade association logos in the building and home improvement sectors, but few offer complete consumer protection. HEIS is the real deal and you don’t pay extra for the safeguards”.
