The missing EWS1 that stopped a sale at exchange
Why external-wall evidence is a board file, not a last-minute survey panic.
In brief
EWS1 & lenders
What it is
EWS1 forms and related lender requirements sit inside the wider Building Safety Act environment. Missing or outdated external-wall evidence can stop a leaseholder selling or remortgaging even when day-to-day management looks calm. Boards that cannot produce the file discover the problem at the worst moment: an exchange.

EWS1 & lenders
Hold the evidence
before exchange asks for it.
EWS1 sits in the Building Safety Act environment. Boards that cannot produce the pack discover the problem when a leaseholder is trying to sell.
A management file, not only a survey
External-wall evidence for lenders
- Someone has to commission, store, and update the evidence.
- That is an Accountable Person / board task where the building is in that environment.
- ProperSafe™ is the planned home for the pack.
Confirm whether you need one
Lender practice and construction type decide. Do not assume every block, or none.
Qualified professional issues it
Residentive coordinates specialists where instructed. The signature on the form is not ours.
The Challenge
The sale is the moment you find the file is missing.
Lender practice is not one-size
Height and construction drive whether an EWS1 is required. Confirm against current lender and government guidance for your block.
Someone has to pay for the form
Usually the service charge or reserve, subject to the lease and any qualifying consultation.
It belongs in the Golden Thread
EWS1 is one artefact in a wider safety evidence set. See the Accountable Person article.
Residentive does not issue the form
The form is issued by a qualified professional. The platform is designed to hold the management file.
Day-to-day management can look calm while the external-wall evidence is outdated or never commissioned.

| Who signs the form? | A qualified professional | Still a qualified professional |
| Who pays? | Often unclear until the invoice arrives | Service charge or reserve, subject to the lease |
