Do not go near them. Very rude staff. They do not provide you with statements only after asking at least twelve times they finally will send you one. You have got to argue with them about everything and would be much better off with doing all on your own. Finally when you got rid of them, which only works when you cancel your lovely tenants as well, you will receive a letter from the Inland Revenue asking to review your rental income.
Do not go near them. even the clauses in their contract are partly against the law. I am still wondering that they are still in business.
