Your number 1 responsibility is to pay your rent in full and on time. Not doing so would put you in breach of your tenancy agreement and at risk of losing your home.
Look after the property. Keep it clean, and take care of any furniture and appliances. Don’t attempt any repairs or decorating without first contacting your Landlord or Agent to seek permission and guidance. If you notice any issues contact your Landlord/Agent to arrange repair. Not reporting minor issues that turn into major problems can be a risk to your deposit.
In an emergency situation (out of office hours) for instance a pipe has burst, or the boiler has stopped working follow our guide on how to get help.
Get familiar with how the boiler and major appliances work. Find out where the stop cock, fuse box and any meters are located. Much better to know now, than wait for an emergency to try and find them. Ask your Landlord or Agent if you need to.
Last but not least be considerate to the neighbours. Anti-social behaviour could get you evicted, so just be considerate of the neighbours.
