About Us


Since 1959, when our father started a window-cleaning business on the Grosvenor Road, Belfast, Grosvenor Services has never stopped growing. 

As a family business, we have remained true to our core values, namely striving for excellence, a commitment to delivering results and forging long-term relationships built on trust with our staff and our clients.

We are privileged to work with some of the leading organisations in the countries in which we operate and are proud of the enduring relationships we have with them. 

The way our service has evolved over the years epitomises our passion for understanding what is important to our clients. We know that our success depends on being relevant and consistent in what we do, so listening to our clients and tuning into their changing needs has always been a priority.   

Successfully working with world-class companies which adhere to world-class standards has given us a platform for delivering an award-winning service. This is important to us. Our future depends on our existing clients. We believe that our clients stay where they are looked after.

Technology has a big part to play in our industry today. Our expertise in technology systems means we can help our clients deliver their services more efficiently and optimise their building and business performance.

Headquartered in Sandyford, Dublin, we have a modern, accredited training centre in Magna Business Park and our regional Irish operations offices in Cork, Athlone and Belfast ensure we serve clients throughout Ireland. 

We operate across the UK and east-coast USA, and as part of a unique alliance of companies we also support pan-European contracts.

We are a privately owned, financially strong company; we can support large contracts, and as we’re family owned, we’re here to stay.

Thanks for visiting the site. Let us know if there’s anything we can do for you.

Bernard McCauley & Rita McCauley

The Grosvenor

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.
