Westminster’s residential property includes grand mansion blocks in Maida Vale and Pimlico, purpose-built flats across Marylebone, and modern tower developments around Paddington Basin and Victoria. Many of these buildings have external wall systems that require EWS1 certification before lenders will approve mortgage applications.
Our surveyors have experience assessing the range of facade types found across Westminster, from the rendered and brick-clad mansion blocks of W9 and SW1 to the contemporary curtain walling and rain-screen systems on Paddington Basin developments. We understand the particular challenges of accessing tall buildings in dense central London locations.
Whether you are selling a mansion flat in Maida Vale, remortgaging a modern apartment near Paddington, or managing a block in Pimlico that requires an external wall fire review, our EWS1 assessments provide the certification lenders require.
Westminster’s high property values mean mortgage lender requirements are particularly impactful. EWS1 certificates are routinely required for mansion block flats in Maida Vale and Pimlico, and for apartments in modern towers around Paddington and Victoria.
Many Westminster residential buildings exceed 11 metres, including the borough’s mansion block stock in W9 and SW1, modern towers at Paddington Basin, and mixed-use developments around Victoria. All fall within the scope of EWS1 assessment.
Westminster facades range from traditional render and brick on mansion blocks to aluminium composite, high-pressure laminate and glass curtain walling on modern developments. Each system requires assessment by a qualified EWS1 assessor to determine fire risk.
RICS valuation guidance requires external wall concerns to be addressed before mortgage lending can proceed on Westminster properties. Given the borough’s high values, delays caused by missing EWS1 certificates can have significant financial implications.

View ServiceCosts depend on building height, facade complexity and the number of external wall types. Westminster mansion blocks with uniform facades may be less complex than modern Paddington Basin towers with multiple cladding systems. We provide fixed-fee quotes after reviewing your building.
Typically two to six weeks from instruction to certificate. Access can be more challenging in central Westminster due to traffic management and scaffold logistics, which may affect timescales for taller buildings in dense locations.
A B2 rating means remediation is likely required before mortgage lending resumes. CSS or BSF funding may be available for qualifying Westminster buildings. Given the high property values, early engagement with the funding process is advisable to minimise financial impact on leaseholders.
Not all Westminster flats require EWS1 certification. Traditional mansion blocks with solid brick construction and no external wall systems may be exempt. However, buildings with render, cladding, or external insulation systems over 11 metres typically require assessment. Lender requirements vary.
