Methodology

Share of London certificates rated C or better, by the year the certificate was lodged. Read this as the efficiency of what was being certified that year rather than of London's housing as a whole — a rising line reflects tightening building standards, retrofits done before sale, and the mix of properties changing hands, and cannot separate them. The current year runs to the most recent complete day rather than to December.
