Twenty years ago, The Clean Space was built around smaller local contracts and a simple belief: cleaning should be delivered with care, consistency and respect for the people doing the work
Today, that same belief sits at the heart of a business employing more than 1,800 people, delivering services to complex, multi-site organisations across London and beyond, and growing from around £5 million to £40 million turnover in just five years.
Over the past two decades, the commercial cleaning industry has changed significantly. Expectations around compliance, sustainability, workforce management, transparency and service reporting have all increased. For The Clean Space, this evolution has not only shaped the business, it has helped define the kind of company it has become.
Charlie Mowat, CEO of The Clean Space, said: “Our growth has never been about scale for scale’s sake. It has come from looking after our people, building long-term client relationships and investing in the systems that allow us to deliver consistently as we grow. The business is very different today from where it started, but the values behind it have stayed the same.”
A People First Foundation
At the heart of The Clean Space’s journey has been a clear and consistent principle: look after people.
From the outset, the company made a conscious decision to reward employees above typical market standards. This was never seen as a short-term incentive, but as a long-term investment in quality, retention and culture.
That approach has helped build a loyal and experienced workforce. Many employees have remained with the business for years, with some staying for more than a decade. Their knowledge, commitment and sense of ownership have played an important role in maintaining service standards as the company has grown.
This people first approach has also shaped the way The Clean Space works with clients. The focus has never been limited to delivering a service. It has been about building long-term partnerships based on trust, responsiveness and accountability.
Building Credibility That Scales
Growth in the cleaning sector depends on trust. Clients need confidence in service delivery. Employees need confidence in their employer. Suppliers need confidence in the business as a reliable partner. Financial institutions need confidence in governance, reporting and strategy.
Over time, The Clean Space has worked to build credibility across each of these areas.
Clients trust the consistency and transparency of the service. Employees trust the company to provide fair pay, stable opportunities and a respectful working environment. Suppliers trust the business as a reliable partner. Banks and financial institutions trust its governance, reporting and growth strategy.
This foundation has enabled The Clean Space to scale without moving away from the values that shaped its early years.
From Organic Growth to Strategic M&A
The company’s expansion has been driven by a combination of organic growth and targeted acquisitions.
Organic growth has remained central to the business, supported by strong client relationships, referrals and a reputation for reliable delivery. Alongside this, strategic M&A has played an important role in accelerating scale and strengthening capability.
Importantly, acquisitions have not been approached as purely financial transactions. Integration has focused on aligning cultures, retaining people and embedding consistent operational standards. This has allowed the business to grow while maintaining cohesion, stability and service quality.
Operational Maturity Through Technology and Data
As The Clean Space has grown, so has the need for structure, visibility and consistency.
In recent years, the company has invested heavily in operational technology, particularly in time and attendance systems, data capture and reporting tools. These systems support accurate workforce management across hundreds of sites, provide clients with clear monthly reporting, and improve transparency and accountability in day-to-day service delivery.
Alongside this, The Clean Space has strengthened its site audit frameworks and introduced structured client feedback processes. This ensures performance is not only monitored, but continuously improved.
Sustainability and Community at the Core
Beyond operations, The Clean Space has maintained a clear commitment to environmental responsibility and local communities.
As expectations around sustainability have increased, the company has continued to focus on responsible sourcing, sustainable practices and supporting local employment. These principles are embedded in the way the business operates and in the decisions it makes as it grows.
For The Clean Space, sustainability is not treated as a separate initiative. It is part of building a better, more responsible business for clients, employees and the communities it serves.
A Platform for the Future
The growth from £5 million to £40 million turnover in five years is significant, but it is not viewed as an endpoint.
Instead, it reflects a business that has built the foundations to play a more influential role within the cleaning industry. With strong systems, a committed workforce and a proven ability to scale, The Clean Space is well placed to help shape the future of the sector, particularly in areas such as workforce standards, data-led service delivery and sustainable operations.
Mowat added: “The next stage is about continuing to raise standards, for our clients, our colleagues and the wider industry. We have built a strong platform, but what matters most is how we use it: to create better jobs, deliver better service and keep improving the way cleaning is valued.”
As the industry continues to evolve, The Clean Space’s journey offers a clear message: sustainable growth is not just about scale. It is about consistency, trust and the people who make it possible.
