External Wall Surveys (EWS1) and PAS 9980 Fire Risk Appraisals in London
Fire Engineering Consultancy provides external wall assessments for residential and mixed-use buildings across London and the South East. Our team supports building owners, managing agents, housing providers, developers and lenders by undertaking EWS1 assessments and PAS 9980 Fire Risk Appraisals of External Walls (FRAEWs).
Our assessments are undertaken by experienced fire engineering professionals and are based on a detailed review of the building’s construction, external wall materials and fire safety measures. The objective is to provide clear, evidence-based advice that supports informed decision-making and regulatory compliance.
EWS1 Assessments in London
The EWS1 process was introduced to support the valuation and lending process for residential buildings where concerns may exist regarding the external wall construction.
An EWS1 assessment typically involves:
Review of available construction information and building records
Inspection of external wall materials and façade systems
Assessment of cavity barriers and fire-stopping arrangements where accessible
Intrusive investigations where necessary to confirm construction details
Completion of the EWS1 form where appropriate
Our team has experience assessing a wide range of building types, including high-rise residential developments, purpose-built student accommodation and mixed-use schemes throughout London.
PAS 9980 Fire Risk Appraisals of External Walls (FRAEW)
PAS 9980 provides a structured methodology for assessing the risk of fire spread over external wall systems. Unlike the EWS1 process, which is primarily used within the lending market, a FRAEW considers the overall life safety risk presented by the external wall construction.
The assessment considers factors including:
External wall materials and build-up
Building height and geometry
Occupancy profile
Means of escape
Active fire protection systems
Fire and rescue service access
Existing risk mitigation measures
Our approach follows the principles of PAS 9980 and focuses on delivering proportionate recommendations based on the specific characteristics of the building. Where remedial works are necessary, we seek to ensure that recommendations are technically justified and aligned with the level of risk identified.
FRAEW Costs
The scope and cost of a FRAEW depend on the nature of the building and the extent of investigation required. Factors that commonly influence the level of assessment include:
Building height and complexity
Number and type of external wall systems
Availability of construction information
Access requirements
Extent of intrusive investigations required
Following an initial review, we can provide a clear proposal outlining the scope of work and anticipated costs.
