I hired a security guard from them over christmas and went to my hometown outside london. they were looking after our property and when i got back, there was no sign that a guard have been there and they sent an invoice to us next day, didn,t look like they provided any service but they charged me. their website is here www.armstrongsecurity.co.uk please beware this company is scam and is operating throughout uk for many things like event security, construction security, close protection and bodyguard services and i dont know what else. big fake company in london, stay away
