About the report

WWF and Friends of the Earth wanted to explore two different scenarios for improving the
British housing stock. The first looks at improving the worst performing homes in the private rented sector and the whole British housing stock. The second looks at achieving a 60% CO2 reduction in 7 million homes by 2020 from current levels. The analysis gives an
indication of what the CO2 savings are across the whole housing stock. The results give the energy, CO2 and fuel bill savings of each scenario along with the cost. 
 
This advance report highlights the finding from the first half of the analysis – improving the
worst performing homes in the British housing stock. This work was undertaken based on
English Housing Survey 2008 data and used the Energy Saving Trust‟s Housing Stock
Refurbishment Calculator.
