Below B on paper

Calculated, not counted

Of the 80 buildings here rated below B, 47 were assessed before 15 June 2022, under carbon factors that have since changed (14 of them electrically heated). On the register’s own record of buildings re-assessed since then, about 20 would come back at B or better on a fresh certificate.

75.1% of electrically heated large buildings rated below B were B or better on their next certificate after June 2022. How this is calculated.
