Review Section 20 notices, major works timing, remediation references, and building safety signals that can create cost or delay risk.
Who this is for
Buyers, brokers and conveyancers reviewing flats where fire safety or external wall wording affects mortgageability or resale confidence.
Why it matters
EWS1 references are usually about lender confidence in external wall/fire-safety risk. The key question is whether the pack contains the current lender-facing document and whether any remediation, cost or expiry issue remains unresolved.
What to check first
- Check whether an EWS1 or equivalent document is actually attached.
- Confirm date, address/block, rating and whether it covers the flat/building in question.
- Look for later remediation correspondence that may supersede it.
- Ask whether lenders have requested additional information.
- Check whether costs are protected, funded, disputed or unknown.
Red flags in the pack
- EWS1 referenced but not supplied.
- Document address does not clearly match the building.
- Historic EWS1 conflicts with newer remediation letters.
- Rating or scope is unclear.
- Lender asks for further information not in the pack.
Evidence to gather
- EWS1 or lender-facing building-safety document.
- Fire risk assessment and remediation updates.
- Landlord certificate/funding correspondence where relevant.
- Insurance schedule and lender/broker notes.
- Section 20 notices for safety works.
Questions to send
- Please provide the current EWS1 or equivalent lender-facing confirmation for the block.
- Is the document still valid and accepted by the intended lender?
- Have any remediation works or safety findings changed the position since it was issued?
- Could any cost fall to leaseholders through service charge or separate demand?
How LeaseLens uses this
LeaseLens finds EWS1 references and verifies whether source evidence is present rather than letting a vague mention create false confidence.
