Today BS 9999:2017 was published. This is a code of practice for fire safety in non-residential buildings and includes many incentives to fit sprinklers.

The standard offers longer travel distances, narrower corridors, stairs and exits, reduced fire resistance and reduced spacing between buildings if sprinklers are fitted. It also relaxes the requirements for fire brigade access and for fire-fighting facilities if sprinklers are fitted. BS 9999:2017 is available here: here.
