Global Security Systems (NW) is a new name for a company established over 50 years ago. Many will know us by our old name of Astbury TV Aerials Limited. In June 2016, the name was changed to better represent the wide range of services we offer.  Global Security Systems (NW) Ltd offers you solutions to all your security needs, and so much more....

More Recently, in 2018, Global Security Systems became part of the Costello's Electrical Brand allowing both companies to greatly benefit from the wealth of experience each has in their respective fields.
