An overview of FRAEWs

A fire risk appraisal of external walls (FRAEW) is a structured assessment of the fire risks associated with a building’s external wall system.

This includes features such as:

  • cladding
  • insulation
  • cavity barriers
  • balconies
  • windows and doors

An FRAEW helps building owners and responsible persons understand the level of fire risk associated with external walls and identify any action that may be needed to reduce risk.

An FRAEW can help:

  • assess the level of fire risk associated with the external wall system
  • inform decisions about proportionate remediation and other risk reduction measures
  • provide information for residents, regulators, lenders and insurers

An FRAEW is only one part of managing fire safety.

It does not replace a fire risk assessment (FRA). The FRA remains the main assessment of fire safety in a residential building. Where needed, the FRAEW supports the FRA by providing a detailed assessment of external wall risks.

All residential blocks with two or more flats are required to have a fire risk assessment (FRA), which should identify whether an FRAEW is required for the building based on the potential risk of the external walls. However, if the risk is sufficiently low, for example if all the walls are masonry / brick built, then an FRAEW may not be required.
