About US

Our history

Loreto Group was founded in 2004 as a professional cleaning company in the greater Dublin area and we have gradually expanded our business to cover a range of corporate cleaning solutions with customers across Ireland.

When we hire, we look out for those with a real work ethic. Our team is diligent in improving the cleanliness and hygiene across a broad range of facilities and institutions. Throughout the COVID-19 pandemic, they’ve supported many essential services in staying clean. We have worked with health care providers, drug rehabilitation services, financial institutions, embassies, security services and childcare facilities.

We are passionately committed to minimising our impact on the environment. We make sure we use the latest technologies here too, reducing our use of plastics, water and chemicals. We work with like-minded suppliers to continue to reduce our footprint.

All of this ensures we continue to shine; delivering an efficient, professional service.


We shine through innovation and rigour,
providing unrivaled cleaning services to our customers,
keeping them healthy and safe
