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 4199 certificates in IG7, the current rating of 65.1 could rise to about 77.7 out of 100. The estimated annual heating cost averages £501 now, and about £380 after the recommended work – an estimated saving of roughly £120 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.
