Policy Conference 2025 | Champions needed for UK C16

Mr MacKenna said the campaign had to get 'specify' right for the campaign to work and needed to find champions in the architectural and engineering professions: "C24 is the default of structural engineers and architects, through training, habit, default and software programmes. We need to move the language to C16 and get them to specify [more C16] at the outset, or nothing else follows on."

In answer to an audience question, Mr MacKenna said the campaign - which is in its very early days - would work with building merchants to increase their understanding of home-grown C16 and its potentially much greater use.

Pat Glennon summarised why it was fine to use C16 for the vast majority of construction projects by saying: "You don't need a concrete beam to hold up a birdcage."
