Our History

The Grosvenor Story

It’s Belfast, the year is 1959.

John Bernard McCauley returns to his hometown after a tour of duty with the US army. With only his bicycle as transportation, he starts a window-cleaning business with his wife Rita. The name Grosvenor comes from the street on which John Bernard was born, the Grosvenor Road, a working-class street of terraced houses near the city centre.

These were the inauspicious beginnings of what would come to be Grosvenor Services, which today employs 5,000 people in two continents and counts some of the most prestigious organisations in Ireland, the UK and USA among its clients.

The McCauleys are still very much at the helm, with John Bernard and Rita’s son Bernard heading up the Irish operation and their daughter Rita running the US division.

The family business ethos is woven into Grosvenor Services’ values and is apparent in how we treat our staff and forge relationships with our clients. It’s one of the things that makes us different.
