Dr. Ciaran Byrne:

Yes it would. Unfortunately there is an element of asking how long is a piece of string because one of the bigger costs of a retrofit is putting in the electrical technology of a heat pump. A heat pump and external wall insulation are probably the two biggest costs. We have had meetings with our colleagues in the Department of Housing, Heritage and Local Government and local authorities and have shared cost data with them. We think the €27,000 is a figure that can bring up a house to a B2 rating. Again, it depends where you start from and where you are going to.
