Inviron has built its reputation over a 75 year period.

Originally incorporated as William Steward in 1933, the company remained private up until 1995, when it was acquired by the European electrical giant ABB. A blend of personal service and corporate professionalism ensued and has carried through to Inviron in its current form.

Inviron is fully owned by its employees following the buy-out of the UK Facilities Management and Building Services activities from ABB at the end of 2003, creating one of the largest employee owned service providers of its kind, within the UK.

In a service environment, where the quality and reliability is dependent on the people providing the services, ownership of the company by those delivering the service provides a differentiator, something we believe sets us apart from all competitors in terms of customer service delivery.
