Who Needs an EWS1 Certificate?
Not all buildings require an EWS1 certificate. According to government guidance, an EWS1 assessment is needed for:
- Buildings over 6 storeys with cladding, curtain wall glazing, or vertically stacked balconies.
- Buildings of 5-6 storeys with significant cladding (25%+ of one elevation), ACM/MCM/HPL panels, or vertically stacked balconies.
- Buildings under 4 storeys where ACM, MCM, or HPL panels are present.
For high-risk or buildings over 18m, specialist testing by qualified fire safety engineers remains mandatory.
