Some landlords will ask tenants to supply a reference. If the tenant can't provide a reference, landlords may ask for a guarantor. If you decide to ask tenants to undergo a credit check you can ask them to pay the cost of this. However, you cannot charge tenants excessive fees for this service. You cannot carry out a credit check without the tenant's consent.
Be sure that you can afford your monthly rent, rates and any other associated costs. If you will be applying for housing benefit or Universal Credit to help you meet the costs of your rent, make sure that you find out how much help you are likely to be entitled to under the Local Housing Allowance rules. Benefit assistance with housing costs will not usually cover your full monthly rent.
