Room-in-roof insulation

If your loft has been converted into a habitable space but it is uninsulated, you may benefit from room-in-roof insulation.

 

Loft conversions that are uninsulated are likely to cost a lot to heat in the winter, may suffer from over-heating in the summer, and can be susceptible to damp, condensation and mould problems.


If your loft was converted more than 10 years ago, it is unlikely to have been adequately insulated by today’s standards.

 

If your loft was converted before 1982 it is unlikely to have had any insulation installed as it was not standard practice before this date.

Room-in-roof insulation can either be fitted in the space between the roof, and the walls and ceiling of the room, or it can be layered over the existing surface of the walls and ceiling, like internal wall insulation. 

Contact the Energy at Home Advice Service for more information about room-in-roof insulation, and to find out if there are any installers currently offering grants to help cover the cost of installation.

A factsheet about insulating a loft conversion from Centre for Sustainable Energy is available here.
