What is an EWS1 form

An EWS1 (External Wall System) form provides independent assurance that your building meets the requirements of the Government’s latest standards. It is not a legal requirement, but some lenders will ask for EWS1 forms before they will consider offering a mortgage.

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).
