What is an EWS1 Form?
An EWS1 form (External Wall System Form) is a certificate used to assess the fire safety of a building’s external wall system, including cladding, insulation, and balconies.
The form must be completed by a suitably qualified professional and helps mortgage lenders understand whether remedial works are required and whether the property is considered suitable security for lending purposes.
Although EWS1 forms became widely requested after 2017, they are not required for every flat or every building. Current guidance means many lower-risk buildings no longer need one.
Do I Need an EWS1 Form to Sell My Flat?
Not always.
In some cases, lenders are now willing to offer mortgages without an EWS1 form, particularly for lower-risk buildings or where remediation funding and legal protections are already in place.
However, requirements can vary between lenders, so buyers may still be asked to provide supporting fire safety information during the mortgage process.
Latest RICS Valuation Guidance
In late 2022, RICS (Royal Institution of Chartered Surveyors) issued updated guidance to help bring greater consistency and confidence to the property market.
Valuers are now able to consider factors such as:
- Whether remediation works are planned
- Funding arrangements for repairs
- Government protections for leaseholders
- Timelines for completion of works
This updated approach has helped more lenders return to the market and has made it easier for flat owners to sell properties affected by cladding concerns.
Will Buyers Be Able to Get a Mortgage on My Flat?
In some cases, they can.
Some lenders are now willing to consider mortgages on flats with cladding where the building meets current guidance requirements.
Buyers will usually need reassurance that:
- Fire safety risks are being managed
- Remediation plans are in place where required
- Funding has been secured for any necessary works
While some buyers may still negotiate on price due to potential disruption from future works, the market is far more active than it was a few years ago.
How to Improve Your Chances of Selling
If you’re selling a flat with cladding, there are several ways to make the process smoother:
- Gather all available fire safety documentation early
- Speak with your managing agent or freeholder
- Obtain details of any planned remediation works
- Keep buyers informed throughout the process
- Work with an estate agent experienced in selling affected properties
Being transparent and organised can help reduce delays and improve buyer confidence.
