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 19252 certificates in RM10, the current rating of 62.8 could rise to about 79.2 out of 100. The estimated annual heating cost averages £599 now, and about £431 after the recommended work – an estimated saving of roughly £167 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.
