Dr. Ciaran Byrne:

-----over the period of Covid. When the wider construction sector was closed, we were closed amid them doing retrofit. When the construction sector opened up, it did so in a variable way. There is a world of difference between building a brand-new house on a brownfield or greenfield estate and going into people's homes, particularly vulnerable people's homes. Even when the construction sector allowed it, a lot of those vulnerable people deferred it and did not want to have people retrofitting their homes during Covid.
