Questions about ensuite installation in Conwy
Can an ensuite go anywhere?
It needs a route for waste water. Gravity drainage is best; where that is not possible, a macerator or pump can work. We check at the survey.
Do ensuites need building control?
New drainage and extraction usually fall under the building regulations, so a building notice or competent-person self-certification is normally needed.
Do you carry out ensuite installation across Conwy?
Yes, across the whole of Conwy, including Colwyn Bay, Llandudno.
Who licenses HMOs in Conwy?
Conwy council licenses HMOs in its area. Landlords must also register with Rent Smart Wales.
