Back in November 2009 we teamed up with Keepmoat, the Great British Refurb and Knauf Insulation to run a competition offering two lucky 10:10ers a full home energy makeover, promising at least a 50% reduction in the energy bills, energy consumption and carbon emissions of the winning property.

Both of the eventual winners hailed from Bristol: William Homoky and Emma Rowlston had a total of £25,000 worth of work done on their homes. For Emma, these improvements cut her home energy bills and carbon emission by over 60%. Thanks to the solar panels included as part of his prize, William saw an incredible 118% cut in his bills (he can now sell surplus energy back to the grid) and an 85% fall in his carbon emissions.
