The Entrepreneurial Revolution: How to scale without losing your soul
One of the UK’s most acquisitive groups, London-based Celnor Group (Celnor) was founded in 2023 by industry expert Simon Parrington and is backed by Inflexion Private Equity. The Group of ambitious, entrepreneur-led businesses is one of the most dynamic and rapidly growing organisations in the Testing, Inspection, Certification and Compliance (TICC) sector.
In just two years it has grown from a concept to a £250m-revenue international group, with over 40 specialist companies – within 4 key Celnor Group divisions – across 60 locations, more than 2,000 colleagues and operations in six countries, including the US, France and Belgium.
The Group’s CEO Simon Parrington tells SME Today why he is investing in entrepreneurs to enable them to harness innovation and scale their businesses without losing their agility or identity.
Britain’s growth story will not be written by conglomerates alone. It will be written by entrepreneurs
Across the UK, SMEs are solving highly technical, highly regulated, mission-critical problems every single day. In sectors like Testing, Inspection, Certification and Compliance (TICC), these businesses protect people, property and the environment. They are agile, expert and close to their clients. Yet many reach a pivotal inflexion point: demand is rising, risk is increasing and the opportunity is bigger than their current infrastructure can support.
The challenge is not whether to scale, it is how to scale without losing identity, culture and the entrepreneurial spirit and spark that made the business a success in the first place. How to protect the heart of the business, which is responding to customer needs and preferences, to ensure the retention and growth of a valued client base.
That question sits at the core of what we are building at Celnor Group.
Why SMEs are different and why that matters
SMEs operate fundamentally differently from larger organisations.
They are closer to their customers. They often have decades of hands-on industry experience embedded in their leadership teams. Decision-making is fast. Solutions are tailored, not templated. There is deep local knowledge and strong accountability, because reputation is everything.
Clients value their responsiveness; the ability to pick up the phone to someone who understands their specific challenge. They value bespoke thinking over process-heavy bureaucracy.
But clients also increasingly want scale. They also value the resources and security typically associated with a larger firm. They want resilience, strong governance, digital capability and geographic reach. They want the reassurance that comes from robust systems and long-term stability.
Historically, entrepreneurs have been forced to choose: stay small and agile or sell out to grow but Celnor provides a crucial third option.
Building a platform for innovation
When I founded Celnor in 2023, backed by Inflexion Private Equity, my ambition was to create a different model; a home for ambitious, entrepreneur-led businesses that wanted to scale without being absorbed and lost.
In just two years, we have grown to a £250m-revenue international group, bringing together more than 40 specialist companies across 60 locations and six countries, with over 2,000 colleagues. We operate across four divisions – Built Environment, Safety & Compliance, Risk Management and Analytical Sciences – supporting more than 20,000 clients.
But growth for us is not about consolidation for its own sake. It is about harnessing and driving innovation.
Entrepreneur-led businesses are natural innovators. They adapt quickly to regulatory change. They develop new methodologies. They spot gaps in the market. What often holds them back is not creativity, but capacity; limited access to capital, technology infrastructure or strategic bandwidth.
Our role as a Group is to remove those constraints.
Through what we call our Enablement Model, we provide the backbone – HR, finance, IT strategy, digital transformation, marketing and M&A support. Operational leadership remains within each of our four divisions. The entrepreneur still leads, the brand remains and the culture is protected.
But now innovation can scale.
The benefits of being part of a larger Group
For SMEs, joining a larger group should never mean losing autonomy. It should mean gaining leverage.
Being part of Celnor allows our businesses to collaborate across disciplines. Instead of operating in silos, our companies can combine strengths, share best practice and pursue larger, more complex opportunities collaboratively.
Clients benefit from a single, trusted ecosystem rather than a patchwork of disconnected providers. They receive the flexibility and personal service they expect from a specialist SME, alongside the resilience, governance and financial security of a larger organisation.
Colleagues benefit too. They are exposed to broader career paths, leadership development and cross-group knowledge sharing. We have invested more than £1m in training, technology and R&D, and our leadership and management programmes are designed to ensure that as we scale, capability scales with us.
Crucially, risk is reduced. Entrepreneurs who once carried the weight of compliance, systems investment and growth financing alone now have a platform and support network beneath them. That security enables bolder thinking.
Protecting identity while accelerating growth
The fear of losing identity is real and justified if growth is handled poorly.
Brand equity, local relationships and culture cannot be recreated once dismantled. We promote from within where possible and we invest in strengthening leadership teams rather than replacing them. We encourage continuous improvement, whilst maintaining heritage.
We look for businesses with an ambitious mindset; progressive, open to change, ready for modernisation. The entrepreneurial energy must already exist. Our job is to amplify it, not dilute it.
Scaling without losing identity requires clarity of purpose. For us, that purpose is trust, collaboration and growth. If a decision enhances those three pillars, we pursue it. If it undermines them, we rethink it.
The next era of SME growth
The compliance landscape is becoming more complex. Regulation is tightening. Clients expect digital integration and real-time insight. International expansion is increasingly relevant even for traditionally local services.
In that environment, standing still is not an option.
The entrepreneurial revolution we are witnessing is not about small businesses remaining small. It is about creating structures that allow them to become more impactful and more resilient without becoming faceless. To provide investment to enable them to implement the latest advances in technology and innovation to offer market leading solutions to their customers.
When you combine entrepreneurial drive with structured support, you create something powerful: businesses that retain their identity, deepen their expertise and expand their reach. Businesses that protect what made them special while unlocking what they could become.
For me, that is the future of scaling SMEs; not surrendering independence but strengthening it through collaboration.
And in doing so, building lasting value for clients, colleagues and the wider economy.
This recent comment from Gerry Nuttall, Director of Southern Operations at one of the Group’s companies, MSS, sums it up well;
“Over the past two years, being part of Celnor has been transformational for MSS. With the Group’s support we’ve been able to rebrand, launch a new website, secure new offices and open our Derby location, allowing us to expand into new markets and support more clients. Being part of Celnor has opened up opportunities that simply wouldn’t have been possible for us as an independent business. We’re now collaborating across the Group to support major highways projects across the UK, which is a fantastic position for MSS to be in as we continue to grow.”
