Loft & roof insulation

Book Loft & roof insulation

Loft insulation involves laying insulating material, typically rolls or blown-in fibre, between and over the joists in your loft. For room-in-roof insulation, insulating boards or rolls are fitted between and over the rafters, turning an unheated space into a warm one.

When do you need a Loft & roof insulation?

If your loft has no insulation, or less than 270mm (11 inches) of insulation, an upgrade is highly recommended. It's one of the most effective and cost-efficient ways to improve your home's energy performance.

What happens on the day

A professional will access your loft space, prepare the area, and then install the chosen insulation material to the recommended depth. For room-in-roof, it will involve insulating the sloped ceilings and gable walls.

How to prepare

  • Clear all items from your loft or roof space
  • Ensure safe and clear access to the loft hatch
  • Inform the professional of any hidden wiring or pipes
  • Protect floor coverings on the access route

How to improve your result

  • Ensure loft insulation is not blocking eaves ventilation
  • Consider insulating the loft hatch itself for maximum benefit
  • Install a loft ladder for safe and easy access to your insulated space
