National Association of Loft Insulation Contractors



  • This Association represents the loft insulation contracting industry and its material suppliers, upholding technical and professional standards.
  • Insulation of the loft is the starting place for cost effective insulation. As much as 20% of heating costs can be saved (government literature).
  • Building regulations require loft insulation to 0.25W/m²K (a depth of 150mm) and to 0.2W/m²K (depth of 200mm) in less energy efficient buildings. The latter is the economic depth that should be applied to all existing buildings today. This can be achieved by topping-up the existing insulation.
  • Professional contractors are important to ensure thermally effective installation, with attention to adequate ventilation in the loft and lagging of tanks, pipes and loft hatches. Association members offer good quality workmanship and use only approved (to British Standard 5803) materials and processes. This includes both mat and blown systems throughout the UK.
  • NALIC offers information on loft insulation and local Members' list.
