W1C is around the national average for energy efficiency.
Looking at the energy data for W1C, this Westminster district scores an average of 70 out of 100, placing it around the national average. Compared to the national average of 67, that puts W1C around the norm for England and Wales. The most common rating band is C, with 16.7% of homes rated A or B and 75.0% in the C or D bands.

This is broadly in line with the national average of 67 — neither particularly efficient nor particularly wasteful.
What percentage of homes in W1C are rated F or G?
0% of homes in W1C fall into the F or G bands — the lowest energy efficiency ratings. Nationally, the figure is 2.9%.

Landlords should note that F and G rated properties cannot legally be rented out under current MEES rules.
