    Brief

    EWS1 (External Wall System) Assessment is a mortgage valuation tool developed by RICS, UK Finance, and the Building Societies Association to evaluate external wall systems for lending and property valuation purposes. This assessment is designed to support mortgage lenders in determining property value and lending decisions related to external wall composition and condition. It is not a life-safety certificate and does not certify building safety compliance. Suppliers providing EWS1 assessment services should be qualified surveyors or assessors accredited by RICS or recognized by mortgage lenders. This opportunity is relevant for organizations offering building surveying, property valuation, or mortgage support services in the UK market.
