Use a written tenancy agreement. Although this is not legally required, it minimises the likelihood of fallout (and subsequent legal action) over terms.
Provide contact details. You cannot be an anonymous Landlord. Tenants have a legal right to know who their landlord is and their address. It is in fact a criminal offence for an agent to not disclose the landlords name and address within 21 days, if requested.
Protect your tenant’s deposit in a Tenancy Deposit Protection scheme. This is a legal requirement if you use an assured shorthold tenancy agreement.
Provide the prescribed information when granting any tenancy. This includes a gas safety certificate, EPC and the latest version of the “How to Rent” government guide. Failure to do this may impact your ability to evict the Tenant in future.
Safety first. Be sure to keep up to date with your safety obligations. For example, your annual gas safety check, your five-yearly/change of tenancy electrical checks and routine fire/carbon monoxide alarm checks.
