Insulation services are carried out on behalf of Marks and Spencer plc by M&S approved installers. M&S loft and cavity wall insulation is partly funded by Scottish & Southern Energy through the Government's Carbon Emission Reduction Target (CERT) programme.

^^£610 figure is based on a 3 bed semi-detached with no existing insulation. Source; Energy Saving Trust. £610 is the maximum value of insulation that may be installed without charge. If you are not the homeowner, you must seek the owner’s written permission before arranging installation. Not all properties will be suitable for insulation. You will not be eligible for free insulation if you already have pre-existing cavity wall insulation or loft insulation that is more than 60mm thick, or if we are unable to insulate at least two thirds of the total loft space or wall cavities. Funding is not available for under tile insulation or where there is already more than 150mm/6 inches of existing loft insulation. If you have a large or non-standard property, or if we need to use specialist systems or equipment to carry out the work, then there will be a charge, but you will be told about this at the time of the free no obligation suitability assessment (you will not be able to benefit from the free insulation offer unless you agree to the additional work and costs). Offer applies to M&S Energy customers only between 16 January 2012 and 14 April 2012. Offer can be withdrawn at any time due to circumstances beyond our reasonable control.
