I propose to take Questions Nos. 569 to 572, inclusive, together.

While my Department does not have specific figures for the estimated cost of installing or converting the heating systems of social or affordable homes, the Regulatory Impact Assessment (RIA) for 2018 amendments to Part L of the Building Regulations in relation to dwellings, concerning homes irrespective of their tenure, set out some relevant information.

The cost of replacement gas boilers, oil boilers and high heat retention electric storage heating for a small bungalow or semi-detached dwelling, as set out in the RIA, is as follows: Gas Boiler €1,973 - €2,390; Oil Boiler €3,215 - €3,633; high heat retention electric storage heating €3,215 to €3,633. The cost of an electric heat pump only, for a small bungalow or semi-detached dwelling, as set out in the RIA, is €8,899 to €10,082.

When installing an electric heat pump in an existing dwelling, a fabric upgrade is required to reduce the heat demand and ensure the effective operation of the heating system. The estimated cost of a fabric upgrade combined with a heat pump, is in the order of €40,000 for a typical house. The cost of an electric heat pump on its own is approximately €10,000. The exact cost would depend on the age, size and construction of the dwelling being upgraded.
