Development within the greater London is required to demonstrate carbon reduction in line with Policy 5.2 of the London Plan and implement an energy hierarchy more commonly termed ‘Be Lean, Be Clean, Be Green’.

The Local Plan of individual boroughs must also be considered and measures included to satisfy their commitment to energy reduction, decarbonisation and air quality. It can be a nuanced and difficult to navigate the process, even more so now that the electricity grid has seen such de-carbonisation that energy strategies defined by outdated building regulation calculations are being encouraged to adopt alternative approaches.
