Ms Caoimhe Hope:

We recognise that the existing supply was built to the standards of the time. Much of the private supply is quite new in its ability so we can have a look at that as well under our overall decarbonisation plan. However, being able to decarbonise the current stock would be outside the scope of the Department as it currently stands. On design standards going forward, we can ensure that any new supply meets the decarbonisation standards.
