<p>The following table shows the number of retro-fit installations of cavity wall, loft and solid wall insulation through Government schemes each year between April 2008 and April 2012. Historic figures for the number of properties with insulation measures installed dating back to 1976 are available in 'Energy Consumption in the United Kingdom' in tables 3.15a and 3.15b<Sup>1</Sup>. The historicfigures are not comparable with those below due to a differentmethodology employed for the new series which enables estimates on aquarterlybasis.</p><p>This publication can be accessed from the following link:</p><p>http://www.decc.gov.uk/media/viewfile.ashx?filetype=4&filepath=Statistics/publications/ecuk/4186-ecuk-domestic-2010.xls&minwidth=true</p><p><table><thead><tr><td valign="top">Thousand<br /></td></tr><tr><td valign="top">Measureinstalledbetween:<br /></td><td valign="top">Cavitywallinsulation<br /></td><td valign="top">Loftinsulation<br /></td><td valign="top">Solidwallinsulation<br /></td></tr></thead><tbody><tr><td valign="top">April2008 and April2009<br /></td><td valign="top">560<br /></td><td valign="top">660<br /></td><td valign="top">10<br /></td></tr><tr><td valign="top">April2009 and April2010<br /></td><td valign="top">590<br /></td><td valign="top">1,420<br /></td><td valign="top">20<br /></td></tr><tr><td valign="top">April2010 and April2011<br /></td><td valign="top">470<br /></td><td valign="top">980<br /></td><td valign="top">10<br /></td></tr><tr><td valign="top">April2011 and April2012<br /></td><td valign="top">520<br /></td><td valign="top">1,130<br /></td><td valign="top">30<br /></td></tr></tbody><tfoot><tr><td valign="top">Source:<br />Estimatesof home insulation levels in Great Britain.
