The Royal Institution of Chartered Surveyors (RICS), the Building Societies Association (BSA), and UK Finance have agreed a new process for the valuation of high-rise buildings, called the External Wall Fire Review process (EWFR).

  • The new industry-wide valuation process which will help people buy and sell homes and re-mortgage in buildings above 18 metres (six storeys).
  • The industry is also encouraging the owners of these buildings to proactively pursue independent testing of external wall materials to safely speed up the process for buyers and sellers.

The External Wall Fire Review process is designed to overcome issues that have arisen preventing property owners, in particular leaseholders, from buying, selling or mortgaging their properties.

The new External Wall Fire Review process will require a fire safety assessment to be conducted by a suitably qualified and competent professional, delivering assurance for lenders, valuers, residents, buyers and sellers. The Review has been developed through extensive consultation with a wide range of stakeholders. Only one assessment will be needed for each building and this will be valid for five years.

The EWS form must be completed by a member of a relevant professional body within the construction industry with sufficient expertise to identify the relevant materials within the external wall and attachments and whether fire resisting cavity barriers and fire stopping have been installed correctly.

MPG Chartered Surveyors have qualified staff in London who can complete these reviews.
