The Independent Expert Panel (IEP) and the Building Research Establishment (BRE) did not directly assist London Fire Brigade (LFB) with the investigation at Samuel Garside House. The IEP’s role is to advise Government, rather than to assist fire services with investigations. LFB did facilitate BRE attending the incident to gather data for MHCLG’s building safety programme, but BRE were not commissioned to be there in to support either the police or fire service. LFB deployed specialist fire safety and fire investigation officers to the fire. Officers were supported by the Brigade’s Scientific Advisors, who took samples for laboratory testing.
