To ask the Secretary of State for Communities and Local Government, if he will publish all assessments carried out into the costs of retrofitting sprinklers in high-rise, multi-occupied residential buildings since 2013.

No central assessment has been carried out. The costs will vary widely based on the size and age of buildings. Local authorities may have commissioned separate assessments into the costs involved following the Government’s request in 2013 to social housing providers that they consider installing sprinklers into older residential tower blocks.
