The ceremony was presided over by councillor Geraldine Robinson, Lutterworths town mayor.

The new 200sqm site houses offices, demonstration/testing facilities, distributor training room, and a dispatch/parts store.

The firm marked the occasion with a black-tie summer ball for 120 specially invited guests.

"It was just a means of saying thank you to everyone that has supported us since we started out over seven years ago," said managing director Graham Harris.
