The EWS1 assessment is a crucial step in ensuring the fire safety of high-rise buildings, especially in the wake of the Grenfell Tower tragedy. This form determines whether a building’s external wall system (EWS) is safe from fire hazards, focusing on cladding and insulation materials. Whether you’re a Property Owner, Building Manager, or Contractor, preparing for an EWS1 assessment is essential to comply with UK fire safety regulations and safeguard occupants.
Understanding the EWS1 Process
Introduced in 2019, the EWS1 form was developed to address fire safety concerns in high-rise buildings, particularly those with combustible cladding. It applies to buildings over 18 meters or those where residential properties face significant fire risk.
The assessment evaluates the external wall system (EWS), including cladding, insulation, and fire barriers, to determine compliance with fire safety standards. The outcome dictates whether the building meets the required safety standards and whether the EWS1 form can be signed off.
Key Steps to Prepare for an EWS1 Assessment:
1. Gather Essential Documentation
Having the necessary paperwork ready can streamline the EWS1 inspection process. Key documents include:
Building plans & technical drawings – Essential for understanding the structure and identifying potential risks.
Fire safety certifications – Previous fire audits and certifications can help demonstrate compliance.
Cladding and insulation materials – Documentation proving fire-resistant materials, such as fire test certificates.
Previous inspection reports – Insights from past safety checks can highlight existing hazards in the external wall system.
2. What Happens During an EWS1 Assessment?
An EWS1 assessment involves a physical inspection by a Fire Engineer. Here’s what to expect:
Step 1: Visual Inspection of External Wall System
A thorough exterior inspection to identify:
Cladding materials – Checking compliance with fire safety regulations. Combustible cladding may require removal.
Insulation type – Ensuring it meets fire resistance standards.
Fire barriers – Looking for gaps or missing barriers that could allow fire to spread.
Step 2: Firestopping and Service Penetration Inspection
Service penetrations (pipes, cables, vents) are checked for proper firestopping.
Ensuring fire-resistant materials are used and correctly installed.
Identifying gaps or cracks that could compromise fire containment.
Step 3: In-Depth Evaluation of the Wall System
Removing small sections of cladding to inspect underlying materials.
Checking fixings, joints, and structural integrity.
Ensuring cladding is securely attached and meets fire safety standards.
Step 4: Final Report & EWS1 Sign-Off
Once inspections are complete, the Fire Engineer compiles findings into the EWS1 report. If compliant, the form is signed off. If issues are found, remediation steps are outlined.
3. Common Issues That Delay or Prevent EWS1 Sign-Off
Non-compliant cladding – Some buildings may still contain flammable cladding that doesn’t meet current regulations.
Improper firestopping – Poorly installed firestopping around service penetrations can lead to EWS1 failure.
Lack of proper documentation – Missing fire test certificates can slow down the assessment process.
4. Work with an Experienced Fire Safety Consultant
Navigating the EWS1 process can be complex, but working with an experienced fire safety company can help:
Conduct a fire safety audit to identify potential risks.
Provide guidance on cladding remediation and firestopping.
Ensure all documentation is organised before the assessment.
5. Ensure Proper Certification & Fire Testing
To pass an EWS1 assessment, your building must comply with:
Building Regulations 2010 (Part B) and BS 8414 fire safety standards.
The Fire Safety Order (2005), ensuring fire prevention measures protect building occupants.
Properly preparing for an EWS1 assessment ensures your building meets UK fire safety regulations. By gathering key documents, conducting pre-assessment inspections, and working with fire safety experts, you can minimize delays and ensure compliance.
