The realistic uplift

Each energy certificate lists the improvements an assessor recommends and the rating the home would reach if they were done. Averaged across 3155 certificates in EC1R, the current rating of 70.7 could rise to about 76.1 out of 100. The estimated annual heating cost averages £477 now, and about £374 after the recommended work – an estimated saving of roughly £103 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.
