An HMO ensuite is a small private shower room, with a WC and basin, built into or next to a letting room. In Cardiff, a city of around 350,000 people, the work is planned around the HMO rules for Wales and the council’s written HMO standards. With students as well as working sharers renting in Cardiff, we plan bigger jobs for the gap between academic-year tenancies where we can.
