The extension of mandatory electrical safety regulations to social housing through the 2025 regulations has created new legal duties for registered providers, including five-yearly electrical installation condition reports (EICRs) and strict 28-day remediation requirements for unsatisfactory reports. While these changes aim to raise standards and align social housing with the private rented sector, they have also generated significant confusion and inconsistent practice across the sector.

This briefing aims to provide a clear, comprehensive and practical guide to the four EICR classification codes – C1 (danger present), C2 (potentially dangerous), FI (further investigation required) and C3 (improvement recommended) and explains how landlords should manage them.
