Get Licensed is doubling the number of security guard courses after the Olympic organisers have been forced to double the number of security guards to protect the games.

A document obtained by the Get Licensed reveals that more than twenty thousand 20,000 guards are now needed next year - twice as many as the previous estimate.

It takes the total cost for civilian security guards at venues to £432 million -nearly 15 times the £29 million figure in London's original Olympic bid.

The huge increase in the number of guards required is a major concern for the organisers which gives plenty of oppurtunity to SIA Licence holders.

The guards hired will man scanners around the Games venues and will carry out airport-style security searches.

According to previous assessment 10,000 personnel were required. Locog have reassessed their position subsequently and now anticipate that they will need substantially more. Some recent estimates suggest 20,000+ at peak."

Although Locog is a private company, the document says taxpayers are likely to be liable for the extra cost.

It adds: "Locog's new assessment of their guarding requirement would place a further burden on Government of £100 million-£150 million."

The organising committee announced this year that it had hired the security firm G4S to provide the guards needed for the Games, however G4S will struggle to recruit 10,000 additional guards.

The bill for guards is on top of the separate Home Office security budget of £475 million for policing the Games. A further £125 million reserve fund is also available to the Home Office under spending plans announced last year.

Get Licensed is increasing the number of SIA Licence linked Security Guard courses to fill in the gap.
