Our Story

Helping our clients reach and maintain the highest standards of hygiene and compliance.

The Halcyon story

Halcyon was founded in 2004 when Peter Kirwan bought out a small contract-cleaning company. Over the years Halcyon’s offerings expanded to include a range of specialist and innovative hygiene services. Halcyon is now the largest hygiene services company in Ireland and is growing exponentially in the UK. Core to the success of our business has been our commitment to staff training and development to ensure we can certify work to the exacting standards of industries such as pharmaceutical, medical-device manufacturing and healthcare. This is why Halcyon won Ireland’s Cleaning Specialist of the Year in the 2020 Prestige Awards.

The Halcyon difference


We’ve spent the past 16 years perfecting our quality cleaning methods and systems.


Halcyon has a non-negotiable stance on maintaining standards of compliance which sets us apart from other commercial cleaning services companies. Unique to Halcyon is the fact that we carry Professional Indemnity Insurance, which enables us to certify our work as compliant with TR19 regulations.


Central to the company’s growth and success has been Halcyon’s ability to create and maintain long-term relationships with clients and distinguish ourselves in the marketplace through proactive problem solving and innovation, providing the highest level of quality, service and commitment to each and every client.


Halcyon is committed to continuously drive innovation and invests in leading technology to answer the evolving hygiene needs of businesses, to ensure the company sets the standard in the hygiene services industry across Ireland and the UK.
