A London commercial cleaning company built on one standard: the work in your specification gets done, and somebody checks it.
We clean GP surgeries, medical centres, schools, offices, factories and warehouses across London and Greater London, with airside and cargo teams at Heathrow.
The work is done by our own trained cleaners, never handed to subcontractors. Behind them is a management team that visits sites, inspects the work against the written specification and acts on anything that slips.
Our head office is in Leighton Buzzard, with local branches in Pinner and Twickenham so a manager is never far from your building.
Clinical areas, done properlyColour-coded equipment and a written schedule agreed with the practice.
The same four steps whether you run a two-room surgery or a multi-storey office.
A manager walks the building with you and notes the rooms, floors, risks and opening hours.
You approve exactly what is cleaned, how often and when, with a fixed price, before work starts.
Our own DBS-checked cleaners start on the agreed date, with the equipment and products supplied.
Managers check the work against the specification and act on anything that slips.
Practice managers, school business managers and facilities teams ask us the same questions. These are the answers.
ISO 9001 certified. Our quality management system is independently audited, so standards do not depend on who happens to be on shift.
Every cleaner is DBS checked and passes 5-year referenced background checks before starting.
Our Heathrow teams hold TSA vetting for airside and cargo environments.
Colour-coded equipment and methods in GP surgeries, clinics and medical centres.
Carried out by IPAF-licensed staff, for warehouses, atriums and production areas.
We are fully insured and send copies of our certificates on request.
Every task, frequency and time slot is written down and agreed with you.
We keep the same cleaners on your site wherever we can, so they learn your building.
Our phones are answered 24 hours a day, 365 days a year.
One-off and specialist cleans need no contract at all.
