The Tenancy Terms Regulations (Northern Ireland) 2007

Repairs

2.  Your landlord is obliged to keep in repair all gas fittings, flues and installations. Your landlord must also provide you with a copy of the record of the required safety checks made in relation to gas appliances or flues, or, in certain circumstances, display prominently in the dwelling-house a copy of that record. Responsibility for other repairs is determined by your tenancy agreement but you can get help from the environmental health department of your local council for some items of disrepair.
