TTF signs Building a Safer Future Charter 21 May, 2021 SHARE TTF joins major contractors, housing providers, local authorities and trade bodies in helping to change the culture around building safety. The Timber Trade Federation has taken the positive step of becoming a Registered Signatory to the Building a Safer Future Charter. The BSF Charter is a proactive response to Dame Judith Hackitt’s Building a Safer Future Review in the wake of the Grenfell Tower tragedy. The Charter is administered by a not-for-profit independent organisation, set up to encourage collaboration, drive change, and ultimately to transform the culture around building safety.
