What insulation adds in N19
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 20315 certificates in N19, the current rating of 68.2 could rise to about 74.7 out of 100. The estimated annual heating cost averages £448 now, and about £343 after the recommended work – an estimated saving of roughly £105 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.
