Dig a little deeper and what do new insulation figures actually reflect?
Last week the Department for Energy and Climate Change (DECC) released figures for what local authorities have managed to do when it comes to insulating homes.
Many thousands of homes have been improved through the Government's Carbon Emissions Reduction Target (CERT), but it's not possible to compare authorities up and down the country on a like-for-like basis.
The figures, published by the Energy Saving Trust (EST), are released on a regional, council and constituency basis, showing how much loft and cavity wall insulation was professionally installed under the Government's Carbon Emissions Reduction Target (CERT) up until 31 March 2011.
While the numbers praise Birmingham City Council for insulating 12,079 and criticises the Isles of Scilly where no homes have been improved and also points an accusing finger at the councils of Westminster (39 homes); Kensington and Chelsea (177); Hackney (272); and Shetland Islands (349).
But really is this something you can really compare – I'd say no you can't – simply because Birmingham (the metropolitan borough of) has a population in excess of 3.5M people.
The Isles of Scilly on the other hand has a population of a little more than 2,000 and is also one of the warmest parts of the country
However, even when you look at the percentage breakdown is hard to compare.
The top five performing local authorities under the CERT scheme over the past three years, in terms of percentage of housing stock insulated, are Kirklees (24.8%); Isle of Anglesey (22.5%); Carmarthenshire (19.2%); South Ribble (19%); Wyre (18.2%) – Birmingham's nowhere to be seen here.
While the five local authorities with the lowest percentage of the housing stock insulated are City of London (0.1%) but has a population of just around 10,000.
But neighbouring boroughs of Westminster (0.3%); Kensington and Chelsea (0.8%); Hackney (1.3%); Hammersmith and Fulham (1.6%) have less of an excuse.
Birmingham certainly deserves recent praise as ovver the last year (April 2010 to March 2011), the largest number of insulation measures were installed in there at 12,079; while Leeds managed 11,244; Bradford (9,078); Fife (8,163); Wiltshire (7,872).
In short you can say well done to Birmingham (but keep it up) brilliant work by Kirklees and come on London what's the wait.
