EWS1 assessments for the City of London’s residential buildings
The City of London contains a number of mixed-use buildings with residential elements where an EWS1 form may be requested for sales, remortgages or valuation review. While predominantly commercial, the Square Mile has residential apartments in modern developments around the Barbican fringes, Aldgate and along the riverside, many featuring contemporary cladding systems that lenders or valuers may ask to understand.
An EWS1 form is lender/valuation-facing information about external wall systems. It is not a life-safety certificate and does not replace statutory fire risk assessment or wider building safety duties.
Our surveyors understand the particular challenges of EWS1 assessments in the City, where residential elements often form part of larger mixed-use buildings with complex facade configurations. We are experienced with curtain walling, rain-screen cladding and composite panel systems common on City buildings.
Whether you are selling a residential apartment in a City mixed-use building, remortgaging in a development near Aldgate, or managing a building with residential elements where external wall evidence has been requested, we provide EWS1 process support in the City of London.
When EWS1 information is requested in City of London
Selling or Remortgaging
Lenders or valuers may request EWS1 information for residential flats in City buildings with external wall systems. Mixed-use developments near the Barbican, Aldgate and along the river are commonly affected by external wall evidence requests.
Buildings Over 11 Metres
Many City of London buildings with residential elements exceed 11 metres. Mixed-use towers, converted commercial buildings and modern residential developments may fall within lender or valuer external wall review processes.
External Wall Materials
City buildings feature sophisticated facade systems including curtain walling, rain-screen cladding, aluminium composite materials and glass panel systems. The mixed-use nature adds complexity, as commercial and residential facades may differ within the same building.
Valuation Requirements
RICS valuers may need external wall information on City residential properties. Given the high values of City apartments and the complex facade systems involved, EWS1 process support can help respond to valuation information requests.

How much does an EWS1 certificate cost in the City of London?
Costs depend on building height, facade complexity and the mix of residential and commercial elements. City buildings often have sophisticated facade systems that require detailed assessment. We provide fixed-fee quotes after reviewing your building.
How long does an EWS1 assessment take in the City of London?
Typically two to six weeks from instruction to certificate. Access to City buildings may require coordination with commercial tenants and building management, which can affect timescales.
What happens if my City of London building gets a B2 rating?
A B2 rating means remediation is likely required. For mixed-use City buildings, the allocation of remediation costs between commercial and residential elements can be complex. Government CSS and BSF funding may be available for the residential portions.
Do all City of London flats need an EWS1?
Only buildings with residential elements over 11 metres or those with specific external wall concerns require EWS1 certification. The Barbican estate and some older residential buildings with traditional facades may be exempt, but most modern City residential developments need assessment.
