Is Number 10 energy inefficient?

A new report shows that flats occupied by Rishi Sunak and Jeremy Hunt have a low energy efficiency rating

Big Zero Report 2022

Although the government took steps to boost the energy efficiency of British homes last week, this ambition does not seem to be shared passionately by the residents of Downing Street.

The most recent Display Energy Certificate shows that 10-12 Downing Street received an “F”.

While the average public building has a rating of 100, buildings with the offices of the Prime Minister and Chancellor saw their score going up from 106 and an E rating to 150 in the year to June, the survey suggests.

The results of the survey, first reported by the Daily Mail, show that carbon dioxide from heating soared by nearly a third from 174 to 226.

Among the recommendations given to Number 10 are photovoltaic panels, ditching the existing modular boilers and installing air-source heat pumps.

A Downing Street spokeswoman told ELN: “The estate has already taken a number of ec0-friendly measures such a full rainwater harvesting system for the gardens and low energy and motion detecting lighting throughout, whilst preserving the heritage of the listed buildings.

“In line with the Prime Minister’s ambition for the UK to be a global leader in clean, green technology and sustainable living, Number 10 looks to build on these measures in the future.”
