Mr. Tom Halpin:

What I was mentioning there was the cost of upgrading an E-rated or F-rated to an A-rated property under our deep retrofit pilot programme as we are experiencing it at the moment.

That is an upgrade so it is retrofitting. It is taking an existing building and upgrading its performance as a housing system. That could cost between €50,000 and €70,000 to achieve. This is to get a building to an A rating.

I also mentioned that under the building regulations people doing renovations that impact more than 25% of the property have do energy efficiency works. This requires them to bring it up only to a B rating. The step between a B rating and an A rating is substantial. I have referenced a number of parts of this, including a deep retrofit pilot and the requirements under the building regulations. One is with regard to achieving an A rating and the other to achieving a B rating.
