Covid-19 Cleaning & Decontamination

With the threat of COVID-19 and other bacteria and viruses that exist among us, it is of utmost importance to sanitise every public space and surface people could come into contact with. GCS UK's top priority is to make any space we disinfect COVID-19 free.

FOGGING: disinfecting & sanitising

Vehicle Cleaning

Vehicle interiors hold millions of particles and pathogen agents carried by the air, people and animals. Fabric and seats absorb bad smells, while stitching and child seats attract bacteria and allergens. GCS UK's Fleet & Vehicle Cleaning service ensures, the thorough clean of your large vehicles or hire fleets, focusing on all high-touch surfaces and fittings. We carry out our vehicle cleaning service with Solvent & Caustic-Free Detergents.

Waste Management & Sanitisation

Whether you're residential, operate a multi-site business or you own a single restaurant, we can tailor our service to suit your needs and minimise disruption to daily operations. From food waste collection to general disposal – we can be on your site within hours of your call/booking to collect, clean and dispose of your waste quickly and correctly.

Out of Hours Cleaning

GCS UK will ensure your premises are maintained, regardless of your operating hours. The industry you operate in may inhibit a regular cleaning schedule, but we avoid this by delivering out-of-hours cleaning to ensure a professional clean whether or not premises are being used.
