For repairs or problems with the property, contact your landlord or letting agent in writing and keep copies of your messages. Check your tenancy agreement, as it may explain who is responsible and how to report issues. If the problem is urgent, such as a serious leak, no heating in winter or a dangerous electrical fault, say so clearly and ask what emergency arrangements apply. If you receive no response, contact your local council's housing department or a tenants' advice service such as Shelter or Citizens Advice. A solicitor may be appropriate for serious disputes or possible eviction.
