Intrusive External Wall Investigation

The EWS1 form is designed to be used for residential properties such as blocks of flats (including those owned by housing associations and social housing providers as well as privately owned), student accommodation, dormitories, assisted living, care homes and Houses in Multiple Occupation (HMOs).

The EWS1 form is not specifically designed for use of short-term accommodation such as hotels. EWS1 does, however, apply to an entire building or block so where required, may also be relevant to mixed use.

The EWS process, and resulting form, is a set way for a building owner to confirm that an external wall system on residential buildings has been assessed for safety by a suitable expert, in line with government guidance.

The EWS1 process delivers assurance for lenders, valuers, residents, buyers and sellers. The process was developed through extensive consultation with a wide range of stakeholders including fire engineers, lenders, insurers, valuers, and other cross industry representatives.
