Mr. Andrew Brownlee:

If you have a concrete investment proposal built around that, it is worth considering. At the moment it is demand-led, so if you are a householder you need to make the conscious decision to retrofit, avail of the grants, go through the process and commission someone to do the work.

It is all demand led. By its nature it is all bitty. If you are doing the street-by-street proposal, then investment is being put behind it, which I believe is the really critical aspect of it. That could then be an avenue to upscale things.

The skills issue is a challenge at the moment but that is speeding up, with some 7,000 construction workers trained in retrofitting last year. That is definitely speeding up. We have the capacity to respond but it needs a bit more co-ordination and a bit more investment behind it.
