That depends. If you or your guests have damaged the property or any item provided by the landlord then, yes, you are responsible for arranging or paying for the repair. If you don’t sort out the repairs, the landlord may deduct the cost from your deposit or, if you haven’t paid a deposit, they could bill you at the end of the tenancy.
Whether you are responsible for repairs caused by wear and tear or other factors will depend on the wording of your tenancy agreement. For example, landlords are usually responsible for maintaining appliances such as ovens and washing machines but there might be a clause in your tenancy agreement that passes the responsibility to you.
However, the landlord cannot make the tenant responsible for maintaining the boiler, the central heating system, the general plumbing and the sanitary ware. If these break down, the landlord is responsible for sorting them out, unless you have done something to damage them. For example, if you’ve blocked the sink by pouring fat down or you messed about with the boiler controls, you could have to pay for the repairs.
A landlord is responsible for maintaining the ‘fabric’ of the building, so if the roof leaks, the gutters are broken, the windows are rotten or the garden fence blows away, the landlord should sort out the repairs. However, note that it is the tenant’s responsibility to inform the landlord if they notice a problem, such as a damp patch on the wall. If they don’t and the problem gets worse, the landlord could make the tenant pay towards the cost of the repairs.
