Averaged across 27197 certificates in SE10, the current rating of 74.5 could rise to about 80.1 out of 100. The estimated annual heating cost averages £362 now, and about £306 after the recommended work – an estimated saving of roughly £56 a year.

These are the register's own estimates, averaged across many homes; the figure for any one property depends on its fabric and how it is heated.
