Buckinghamshire is set to get a £160million boost over the next four years as a direct result of the Olympics.
Accountants and business advisers James Cowper has worked out the county is set to get its share of what Prime Minister David Cameron said would be a £13billion boost to the whole nation.
The firm reckons the benefits will be amassed from extra export orders, inward investment and an upsurge in tourism.
Mike Farwell, business services partner at James Cowper, said: “The Games have been an enormously successful UK marketing campaign and my advice to businesses is to take confidence from this and urgently consider how they can harness the Olympic momentum.
“Sustained investment and an unswerving focus on the best outcome have brought the greatest haul of medals for Team GB in 104 years. With a similar sense of purpose and consistent approach, counties across the region can now achieve some swift moves up the economic league table.”
He continued: “The overall figure could be even higher if you also take into account the much discussed feel-good factor and new impetus for volunteering.”
The company, which has offices in Newbury, Oxford, Reading, Southampton, Henley and London, also estimated Oxfordshire is in line to get a £130m boost, Hampshire £400m and Berkshire £185m.
