  • Aerial Fault

    10Verified Review

    My first time using this company. Found through Checkatrade. They made contact promptly and arrived as arranged. Very helpful, friendly and put me at ease straight away. I'd been experiencing a lot of interference from electrical items in my home causing pixelation on my TV. Resorted to streaming for 3 years but eventually decided to get it looked at. The home is old and had a lot of previous work done; lots of aerial cables everywhere. Eventually after a lot of detective work, and removal of defunct/unnecessary cables, I now have over 130 channels."

Company info

Necessity Services Ltd began life as a television aerial & satellite dish, installation and servicing company, formed in 1990 by Mark Crowther.

Since that day we have been living through a technological revolution leading to the world we live in today, where so much in our lives is integrated. It was due to these technology integration developments, that we also began to offer home security burglar alarms, CCTV camera systems as well as broadband related services, such as additional ethernet and wireless access points.

Television, burglar alarms, CCTV and broadband have all become “necessity services” for the home.

We regularly attend Continuing Professional Development Courses and manufacturers presentations, in order to keep our knowledge topped up.

We are proud to have attained CAI+ (Confederation of Aerial Industries), Trustmark, Which? Trusted Trader & Checkatrade status.

We also carry out works in the commercial sector, primarily on behalf of electrical contractors and property management companies, where we install and maintain, communal TV/Sat reception, Door Access intercom, Automatic Opening Vent and structured data cabling systems.
