Read google reviews before booking this company. The engineer LAWRENCE said that the signal in this area is not good enough so he helped us to install the external aerial. However, it was told that accordng to the Housing Associations information we supposed not to install the external aerial. Therefore, we told this company and requested for de-intallation during the cooling period. They said that this is not their responsibilty so we need to pay £114 additionally for de-installation. Of course, I didn't pay them to remove it. Instead of, I paid for another aerial company to remove it and they have good knowledge that this aera should not install the external aerial. TV Aerial/Aerial Force/Speedy Aerials (they are a group of company) are not a honest and professional company so please AVOID!!!!
