Marlowe Critical Services

WCS Group is the Water Treatment and Hygiene division of the UK’s fastest growing critical services business owned by parent Marlowe plc.

Marlowe’s unique strength is that it provides a range of closely related critical maintenance services each of which is delivered by a specialist Water Treatment & Hygiene, Fire & Security and Air Quality division. Individually, these divisions are leaders in their fields but together, form a group that can provide customers with a comprehensive and integrated approach to their safety, regulatory compliance and the upkeep of the building systems they rely on.

That means more convenience, better across the board compliance, greater consistency and specialist support across Fire, Security, Water and Air services.

Our size, range and extensive national footprint give our customers the peace of mind that comes from knowing that they can count on a Marlowe Critical Services company to deliver those mission critical services that are so vital to them every day of the year in every part of the UK.

Collectively, we number over 1,800 specialists, servicing 10,000+ customers, carrying out 750,000+ service visits and helping to maintain over 10 million assets for circa 9% of the UK’s 1.8 million non-residential buildings each year.
