Not worth even one star. These people are absolutely useless, incompetent and deceivers. They simply do not care about they customers. Even though I am still a paying customer they are refusing to conduct the yearly boiler service/check. They also have refused to send me the yearly proof of payment for the tax return purposes. They have a complete disregard for their customers. They rarely answer the phone and they Do Not reply to the emails. So, If I was you I would stay away from this people. Do not waste your money with them. Stay Away from them. They are utterly useless and liars.....
