Londoners are least likely to install cheap energy saving alterations such as insulation in their homes, a new survey has found.
Research by the Energy Saving Trust shows that the five areas with the lowest levels of insulation are all in greater London, while the regions with the highest insulation levels are Kirklees and the Isle of Anglesey.
Kirklees has a 22.5 per cent level of insulation, followed by 18 per cent in the Isle of Anglesey, 14.6 per cent in Carmarthenshire, 13.4 per cent in Wyre and 13.3 per cent in South Ribble.
In London, the worst performing borough is Westminster with just 0.2 per cent of housing stock with professionally installed insulation.
Other badly performing boroughs are Kensington and Chelsea (0.5 per cent), Tower Hamlets (0.5 per cent), Hammersmith and Fulham (0.7 per cent) and Southwark (0.7 per cent).
