The Landlord and Tenant Act 1985 places an implied term in every tenancy that the landlord must keep in repair the structure, sanitary installations and exterior of the property. However this does not cover design faults, only a lack of repair - this is provided for in a decision handed down in Quick v Taff Ely BC.
Landlords can therefore be held liable if they have failed to provide a safe and healthy environment for their tenants. You can use or threaten to use the HHSRS (as above) and ask the environmental department at the local council to carry out a health and safety assessment of the property. They have the power to serve improvement notices on the landlord to remedy any areas which do not come up to standard. The service is free so you have little to lose.However consider that the landlord can give you two onths notice to quit the property if you do not have the benefit of protection of a fixed tenacy contact at present.
I hope the above is of some assistance. If you have no further questions for now I should be very grateful if you would kindly take a moment to rate my service to you today. Your feedback is important to me. If there is anything else I can help with please reply back to me.
