Companies from the West Midlands have smashed through the £500 million barrier in the race to win contracts for the 2012 Olympics.

Latest figures show firms from the region have amassed £515 million worth of deals to supply to the games – more than any other region outside the South east of the country.

A total of 303 firms from the region have won tenders to supply London 2012 from 57 of the 59 parliamentary constituencies in the West Midlands.

The contracts range from Wolverhampton-based Carillion, which landed a nine-figure deal to build the media centre, to Birmingham firm Acme whistles, which will supply whistles for Olympic officials.

Jim Johnston, business manager of the 2012 Games at Advantage West Midlands, said there could be more small deals to come, but a £400 million target had already been passed.

He said: “The West Midlands business community has really done well and stepped up to the plate.

“In the early days it was largely construction contracts – companies like Carillion which is building the International Media Centre which is being handed over next week, and that is hundreds of millions of pounds alone. Then there is Zaun Fencing which has put up the perimeter fence around the park and has since won six or seven other contracts.”

He added: “They are the bigger contracts, but then there are smaller ones like Acme Whistles, who are supplying the officials.”

In all, 57 of the 59 parliamentary constituencies in the West Midlands have won contracts – every one aside from Hodge Hill and Stone in Staffordshire.

Latest figures showed that the region accounted for eight per cent of deals for the London Games – making it the fourth largest supplier out of the nine English regions.

But the geographical breakdown of contract winners is skewed strongly towards the capital and the South-east – with London itself taking 53 per cent of contracts and the South-east 16 per cent, according to figures obtained using the Freedom of Information Act from the Olympic Delivery Authority (ODA).

Other companies from the region to have won deals are Elements Europe, from Oswestry, which is making bathroom blocks for the Olympic Village, while Johnsons Coach & Bus, from Henley in Arden, is supplying coaches for the games.
