EWS1 Forms and Survey of External Walls

Anstey Horne have the largest and most experienced team of qualified surveyors to complete EWS1 forms and issue certificates in the UK

What are EWS1 Forms?

EWS stands for ‘External Wall Survey’.

The external wall consists of the outside wall of a residential building, including any cladding, insulation, and fire break systems for instance.

An EWS1 Form records in a consistent and universal manner the assessments that have been carried out on the external wall construction of residential buildings.

An EWS1 Survey can apply to buildings of any height where specific concerns exist.

The assessment must be conducted by a qualified and competent professional, such as a Chartered Construction Professional as defined on the RICS guidance.

A single assessment is needed per building. Once the EWS1 form has been completed it will be valid for five years, subject to significant use changes or any refurbishments.

For further information on EWS1 Surveys and Forms, our fact sheet can be found here, as well as our EWS1 FAQs.

Why are EWS1 Forms required?

Following the Grenfell fire disaster and the issue of the Hackitt Report (Building a Safer Future) the safety of high rise buildings, particularly residential, has come under increasing scrutiny amid a drive to confirm their safety or to remediate those buildings.

In response, the Royal Institute of Chartered Surveyors (RICS) developed the EWS1 Survey process.

EWS1 forms first came into use in December 2019 and were updated in March 2021.
