The ‘Roadmap of Skills for Net Zero: Competencies for Domestic Retrofit’ report seeks to define some of the core competencies for effectively decarbonising existing buildings. The importance of skills development for effective retrofit work should also be emphasised in local planning strategies, according to the CLC report. These include developing core modules outlining the basic skills and knowledge needed for retrofit work to create safe and lower carbon buildings. This will ensure training materials and infrastructure to deliver courses at the scale required, according to the report. The CLC report warned that poorly executed work risk creating a range of unforeseen consequences.
