In England, letting agents generally cannot charge tenants fees for things such as referencing, viewings or setting up a tenancy under the Tenant Fees Act 2019. Permitted payments can include rent, a refundable tenancy deposit, a holding deposit and certain charges for agreed changes, late rent or ending the tenancy early, subject to limits and conditions. Rules differ in Wales, Scotland and Northern Ireland, so check the relevant government guidance for your location. If you think a fee is unlawful, ask the agent to explain it in writing and consider contacting your local council or a housing adviser.
