How retrofitting the UK’s old buildings can generate an extra £35bn in new money

Heritage and property groups outline plan to boost energy efficiency at historical sites to create jobs, cut emissions and meet net-zero targets

Retrofitting the UK's historicsl buildings, from Georgian townhouses to the mills and factories that kickstarted the Industrial Revolution, could generate 35bn of economic output a year, create jobs and play a crucial role in achieving climate targets, research has found.

Improving the energy efficiency of historical properties - those built before 1919 - could reduce carbon emissions from the UK's buildings by 5% each year and make older homes warmer and cheaper to run, according to a report commissioned by the National Trust, Historic England and leading property organisations.
