Spy Alarms is probably the largest privately owned business installing security systems in the South East, started by Martin Foster after his own house was burgled and he could not find the system he needed from the available suppliers. We have been in business for over 30 years and have more than 17,500 customers – both domestic and commercial – throughout London, Kent and the Home Counties. A large proportion of our work comes from repeat customers and we are now keeping the second generation of those first clients safe. From studio apartments to large country estates, small offices to larger office complexes and industrial/ institutional premises, every competitively priced installation utilises the latest technology together with quality components.
