Mr. Declan Daly:

Yes. It costs €50,000 to undertake a deep retrofit but this is a pilot scheme and only so much finance has been approved for it. There is a backlog of houses ready to go, but the finance for them is not ready.

Regarding materials, any product that we use in our schemes are National Standards Authority of Ireland, NSAI, approved. Everything has to be certified, for example, the wrap-around external insulation, which is usually made from expanded polystyrene, EPS, and the wood fibre. There are also breathable solutions for stone. If a stone or brick structure is retrofitted, a breathable solution must be used. All of the products are NSAI approved. They are also fire rated.
