Mr. Se?n Armstrong:

We worked very closely with the Department of the Environment, Climate and Communications in the midlands trying to pilot this through the midlands retrofit programme in 2021. It was quite challenging. The challenge was to aggregate the private homeowner at the same time as the local authority was retrofitting its housing. We were working to very short programme timelines with the local authorities due to the budget lines. A lot of co-ordination was needed. It was very difficult to aggregate the individual homeowners. The one-stop shops now are being proposed as a method of aggregating private homeowners. There is also the opportunity for them to liaise with local authorities in that respect. There is a piece of co-ordination needed between local authorities and private homeowners. That needs to be facilitated. As the one-stop shops are the aggregators, they may be best placed to facilitate that co-ordination. It was quite challenging to implement at the time.
