Dr. Ciaran Byrne:

That depends because some of them are smaller and some are slightly bigger. KORE Insulation, I believe, has a panel of upwards of 100 contractors who work with them for various measures. So KORE would have panels of contractors who would come in and do different measures. Some contractors specialise in the likes of insulation while others specialise in heat pumps and things like that. So they would bring in the relevant contractors attending on the job. That is the way they do it. Other companies are starting to build all that capacity inhouse.
