We’re pleased to have been named the #1 office cleaning company in London in a new 2026 guide published by Investing in Women.
The guide compared seven London cleaning companies across four areas: compliance and certifications, staff vetting and consistency, service scope and suitability for different types of offices.
SM Cleaning took the top spot, particularly for businesses where audited quality standards, compliance and day-to-day consistency matter.
Why Did They Rank SM Cleaning #1?
A big part of the decision came down to proof rather than promises.
The article highlighted our UKAS-approved ISO 9001 quality management system, along with our approach to staff vetting, pay and retention. It also recognised the breadth of our office cleaning service and our experience working with established property and corporate clients.
That means a lot to us because these are the things we focus on every day.
Good commercial cleaning isn't just about turning up and completing a task list. It's about having reliable people on site, proper processes behind them and clear accountability when something needs attention.
Recognition We're Proud Of
The guide ultimately described SM Cleaning as the top choice for London businesses where certification and consistency matter more than simply choosing the lowest headline price.
We're proud to see the work our team puts in recognised independently.
And as always, we'll keep doing what got us here... looking after our people, staying close to our clients and making sure the standards on site match the standards we promise.
