Optus Glean UK provides commercial cleaning across the City of London — offices, healthcare and CQC-registered settings, industrial premises, retail, education and specialist work — as part of one nationwide contract. Every operative is PAYE-employed and DBS-checked, work follows a written specification, and you pay one fixed monthly fee with a free survey first.
Cleaning across the City of London's business districts
We clean premises right across the City of London. Our teams work throughout the city's main commercial areas — Bank, Liverpool Street, Smithfield, Moorgate, the Square Mile and St Paul's — as well as out-of-town business parks and industrial estates. You will find our operatives around St Paul's Cathedral, the Bank of England, the Tower of London and Leadenhall Market and the surrounding streets. Whether you run a single office or a portfolio of sites across the city, the specification and the standard are the same on every visit.
Every sector in the City of London
the City of London's economy is varied and so is our work here. We clean for banking and finance, insurance, legal services and professional services, among others. That includes healthcare and care settings — including work in and around St Bartholomew's Hospital — to the NHS National Standards of Healthcare Cleanliness 2025 and, for CQC-registered providers, CQC Regulation 15 (premises) and Regulation 12 (infection control), education sites, from City, University of London and Guildhall School of Music and Drama to local schools and colleges and transport hubs such as Liverpool Street station, Bank station and Cannon Street station.
England vetting and regulation
Care settings in England are regulated by the Care Quality Commission (CQC). Operatives are DBS-checked through the Disclosure and Barring Service, with Enhanced DBS checks for school, healthcare and care-setting contracts. All operatives are PAYE-employed by Optus Glean UK — never self-employed or agency labour drafted in per shift — which is what keeps standards and accountability consistent across a contract.
One contract, every the City of London site
Most cleaning firms in the City of London can only cover the city and its immediate area. If you operate sites beyond it, you end up juggling a different local cleaner in each place — different standards, different invoices, no single point of contact. Optus Glean UK gives multi-site organisations one contract, one specification and one account manager across every UK site, with the vetting and TUPE capability to take on a switch cleanly.
From the City of London we also cover the surrounding area, including Islington, Hackney, Southwark and Tower Hamlets.
