Credential has been the lettings agency that let and subsequently arranged the full management of my house in Tooting , London . The helpful and friendly staff at Credential let and managed this property for myself and my family for over 13 years . During this time the management of the property was handled professionally and I had no need to worry about the house . The tenants over this time also remained happy and so I guess this speaks for itself . I have been a bulk landlord for some 44 years and I would say that Credential has provided the best service of the management agents who I have dealt with over this time . I would recommend them to any other landlords requiring a lettings and full-management service .
