Hi Rosemary, I own property in North Wales and have experience in this area. Basically many councils in Wales already charge additional council tax for additional homes (some cases 3x). Selective licensing is different to this and isn't necessarily a bad thing, a lot of councils use it to control a certain standard and level of safety in properties. We have it in some of our north east properties, it's extra work but means council sign off a list of things like smoke alarms, hand rails on stairs and other measures to try and keep landlords accountable and the tenants safe.
