EWS1 Documents

This page applies to London and East SNG customers only

We've combined our customer websites

You can now find all our customer information on this site. As we're still bringing services together following our merger, some content only applies to London & East or to South & West customers.

Please use our postcode checker if you're not sure which region you are in.

Here you can find the EWS1 form (ews - externall wall system) for your building. Where we have one, we have also included a cover letter from the fire engineer, which can be a requirement of mortgage lenders.
