The short answer

Only with clear, written evidence of the cladding type and remediation status. Since Grenfell, lenders may require an EWS1 form (or equivalent) for flats in buildings with cladding, and unresolved fire-safety risk can make a flat unmortgageable and unsellable. Where remediation is funded and documented under the Building Safety Act, a cladding flat can be a sound buy, but never proceed without the paperwork.

The real risk

After the 2017 Grenfell Tower fire, fire-safety scrutiny of external wall systems transformed the market for cladding flats. Buildings with combustible cladding can require expensive remediation, and leaseholders feared being landed with the bill.

The Building Safety Act 2022 introduced leaseholder protections and remediation routes, and many lenders now lend where the building's status is clear, but you need to know which scheme applies, who is paying, and whether works are complete or pending.

An EWS1 form records the external wall system assessment. A satisfactory EWS1, or evidence the building is enrolled in a funded remediation programme, is often what unlocks a mortgage.

What the data reveals

EWS1 form / fire-safety assessment

Records the external wall system rating, frequently required by lenders for flats in affected buildings.

Building Safety Act remediation status

Whether the building is enrolled in a funded remediation scheme and who is liable for costs.

Managing agent / freeholder disclosure

Service-charge accounts and Section 20 notices reveal pending major works and cost exposure.

How to check this exact address

  1. 1Ask the agent whether the building has cladding and whether an EWS1 form exists, and request a copy.
  2. 2Have your solicitor confirm the building's remediation status and any leaseholder cost liability under the Building Safety Act.
  3. 3Check service-charge accounts and any Section 20 major-works notices for pending fire-safety spend.
  4. 4Confirm your lender will lend on the building before incurring survey costs.

Frequently asked questions

Can you get a mortgage on a flat with cladding?
Increasingly yes, where the building's fire-safety status is documented (a satisfactory EWS1 or enrolment in a funded remediation scheme). Without that evidence, many lenders decline, making the flat cash-buyer-only.
Will I have to pay for cladding remediation?
The Building Safety Act 2022 introduced leaseholder protections that limit or remove costs for many qualifying leaseholders. Whether they apply depends on the building and lease, so get specific legal advice on the exact flat.
What is an EWS1 form?
An External Wall System assessment form used to confirm the fire-safety status of a building's external walls. Lenders often require it for flats in buildings with cladding before they will lend.
