Based on its review of existing evidence and engagement with key stakeholders, this research uses the phrase 'complex-to-decarbonise' (CTD) to describe this housing stock, rather than 'hard-to-treat' or 'hard-to-heat'. This research describes different approaches to energy efficiency and low-carbon heating in CTD homes. The Department for Energy Security and Net Zero commissioned DG Cities in consortium with University College London's Institute for Environmental Design and Engineering to conduct this research.}, author = {Kelly, Leanne and Houghton, Ed and Hamada, Amr and Cui, Cheng and Raslan, Rokia} }
