EWS1 Certificate
An EWS1 certificate, also called an EWS1 form, as the two terms mean the same thing, is a fire engineer’s signed assessment of a building’s external wall construction, confirming whether it poses a fire risk. Residential buildings over 11m with cladding, render or another external wall system typically need one, and without a valid form, most lenders won’t approve a mortgage, insurers may restrict cover, and a sale can stall entirely.
