Mr. Brian O'Mahony:

About 162,000. About 500,000 homes would be suitable for solid wall insulation. That would be regarded as a deeper intervention.

In terms of roofs, about half of the homes in Ireland would benefit from further attic insulation. The general rule of thumb would be that homes constructed from the early part of this century onwards are all modern and energy-efficient and homes constructed before that generally might need some improvement if that has not already been carried out. In our schemes we have individual measures schemes, such as the better energy homes and solar PV schemes. We have seen significant growth in the application rate for those scheme since March.
