Unconditional Protection: Why You Must Never Buy Unaudited Solar.

Executive Summary

HIES (Home Insulation & Energy Systems) and EPVS (Energy Performance Validation Scheme) are critical consumer protection frameworks for solar buyers. HIES legally protects your deposit up to 25% of the contract value and provides an Independent Builder's Guarantee. EPVS independently audits all performance claims, ensuring you are legally protected from mis-selling, exaggerated ROI projections, and malpractice. Do not purchase solar without verifying both accreditations.

Eradicating the Cowboy Installer

The solar industry has historically been plagued by exaggerated savings claims and fragile warranties that dissolve when the installer folds. When an installer does not hold an EPVS certification, they are legally permitted to provide unvalidated savings estimates. We do not operate that way. Every financial projection we provide is independently scrutinised and validated by the EPVS Gold Standard before you sign a contract.

The HIES Fortress

A 25-year warranty is worthless if the company goes bankrupt in five years. HIES membership resolves this completely. From the moment you place a deposit, it is insured — up to 25% of the contract value or £5,000, for 120 days. Furthermore, you receive an Independent Builder's Guarantee, meaning your workmanship warranty remains intact and fully actionable regardless of First Choice Solar's future corporate status. Your protection is structurally independent of our survival.
