You should report any suspected faults to your landlord as soon as you know about them. It is their responsibility to investigate, and hire an electrician to do any work if needed. Know your obligations as a tenant and keep in touch with your landlord on a regular basis.
Dulas
Dulas or City Dulas is a village in Anglesey, in north-west Wales. It is situated on the A5025 roadway, near the coastline (Dulas Bay) at only 5 metres (16 ft) over sea level. The village has never held the condition of a city and also "City" is not a recognisable Welsh word, so its beginning is unclear. It might be that the name originated from an Anglicisation of Saith Ty, which is Welsh for "Seven Houses". There are 2 places in Wales just called 'City': City, Powys as well as City, Vale of Glamorgan.
