Yes, if the safety issues in your home are serious and your landlord refuses to fix them then you could contact the Environmental Health Department about the issue.
They may send an environmental health officer to carry out an inspection of the property and they will assess the hazards in your home using the Health and Safety Rating System (HHSRS). If a Category 1 hazard is found then the council must take action. If a Category 2 hazard is found then the council has the power to take action.
