Ready to staircase your home?

Let’s make sure you have all the information you’ll need before you start your staircasing application.

How to proceed with staircasing your home

The process will be easier, and quicker, if you make sure you have all the details required ready to submit with your form.

Have you spoken to your mortgage provider and solicitor? Is your legal paperwork all in hand? If not, please refer to our staircasing guidance

Have you got all the details required for the staircasing application form?


A RICS surveyor (Royal Institution of Chartered Surveyors) will be assigned once we’ve processed your staircasing application, based on your postcode. We’ll contact you within three working days to confirm receipt of your form and give you further instructions.

We’ll work to have you completed on the purchase of your chosen share within three months. We’ll support you and your solicitor to achieve this.

EWS1 (external wall system) forms

EWS1 forms only apply to apartments.

In 2020, the government issued revised guidance on building safety standards for homes within apartment blocks. As a result, buildings of any height are now potentially in scope for requiring the EWS1 (external wall system) form devised by the Royal Institution of Chartered Surveyors (RICS).

EWS1 certification requires a new assessment of the building by a qualified, independent professional to establish if the external wall system meets the new fire risk standards, or whether remedial work is needed.

EWS1 forms are not a legal requirement, but some lenders require one before they’ll offer a mortgage. We'll need to know the status of your EWS1 certification before an application to staircase will be considered.

Check the status of an EWS1 form on your property.
