HI-TECH security firm Westminster Group saw its turnover double last year.

Figures for the period ended December 31 show the Banbury-based firm’s revenues increased by 100 per cent to £5.5m, while pre-tax profit almost doubled to £1.9m.

Westminster specialises in equipment such as bomb jamming, explosive protection and integrated banking.

The company recently won a £1m contract for scanning equipment to be used at airports in Iraq and last month bought security management firm Longmoor Services for up to £2.4m.

Offices have also been opened in Abu Dhabi and Malaysia.

Chief executive Peter Fowler said: “We feel we have barely scratched the surface of the potential market for our services.”
