The Company That Gambled on Doing Things Right

Fifteen years ago, Iain Fraser-Jones made a wager the cleaning industry thought was naive: that sustainability, honesty and integrity could be a business model, not a footnote to one. B Corp certified, with a robust sustainability and carbon reduction strategy, and now turning over £10 million, it’s becoming harder to argue with him.

There’s a line you hear often in facilities management: sustainability is something you do once you can afford it. It sits at the end of the decision tree, not the beginning. Win the contract. Cut the cost. Then, if the margins allow, think about the planet.

Iain has spent fifteen years building a business that treats that logic in reverse.

When Iain founded Greenzest Limited in September 2011, he was making what looked, to some, like an idealistic bet: that a commercial cleaning company could be built around sustainability, honesty and integrity, and could succeed because of those things, not merely alongside them. He wasn’t guessing. He was drawing on more than three decades inside the industry – Group Sales and Marketing Director at Servest UK, senior roles at Lynx Security and The Executive Group – long enough to understand precisely what the sector was getting wrong, and why.

“Iain secures first-class customer relationships by continual attention to detailed customer service,” one former colleague observed. “A true professional with great integrity.”

The bet, it turns out, was well-placed. Today Greenzest employs 470 people, turns over £10 million, holds B Corp certification, is working towards being carbon-neutral, pays the real Living Wage on every contract without exception, and is expanding nationally, entirely self-funded.

Not Marketing Language

Greenzest structures its approach around four principles: Planet, People, Partnership and Productivity. The language is clean. The practice behind it is harder-edged than it sounds.

Planet means genuinely eco-friendly products, energy-efficient equipment, and operations that have a clearly defined carbon neutral plan. People means Living Wage Foundation Employer status: every bid, every contract, no carve-outs. Partnership means working alongside customers – and suppliers – on their own sustainability objectives, not simply fulfilling a spec. Productivity means demonstrating, contract by contract, that ethical data driven operations and cost leadership are not in tension.

The real Living Wage commitment is the one worth pausing on. Greenzest was only the fourth cleaning company in the UK to make the step up from Recognised Service Provider. The effects have been measurable: staff retention sits significantly above the sector average, recruitment costs are lower, and the kind of continuity that customers quietly depend on is visible in the numbers.

“I have been working for Greenzest for eleven years,” one employee has noted.

Eleven years in commercial cleaning. That figure doesn’t need much commentary.

Certified, Not Claimed

Greenwashing is a genuine and growing concern in commercial services. Claims are easy. Verification is harder.

Greenzest holds B Corp certification, independently assessed, audited, and renewed every three years. Companies that don’t demonstrate continued improvement risk losing it.

Fewer than 10,000 businesses worldwide hold B Corp status. In commercial cleaning, it remains rare enough to be meaningful. For procurement teams navigating a sector where sustainability language has significantly outrun sustainability practice, it functions as a useful signal: these commitments have been examined by people with no stake in the outcome.

Growing Into What It Always Was

The commercial cleaning market has changed considerably since 2011. Sustainability is now embedded in procurement frameworks. ESG criteria shape supplier selection. Customers who once treated it as a differentiator now treat it as a baseline requirement.

Greenzest didn’t pivot to meet this moment. It was built for it.

Headcount has grown 40% in recent years, driven by both reputation and active business development – particularly in the shared office sector, where hybrid working has reshaped demand patterns and where sustainability credentials carry genuine weight with operators and landlords.

The leadership team has grown alongside the business: Iain Fraser-Jones as Founder and Managing Director, Vince Treadgold as Commercial Director, Travers Hathrill as Sales Director, Bruce Herbst as Operations Director, and Andrew Henderson as Transformation and IT Director.

From a single founding belief in 2011 to a national operation turning over more than £10 million: B Corp certified, Carbon-Neutral focused, Living Wage fully accredited, leaders in UhUb staff training and entirely debt-free. The cleaning industry rarely produces businesses with a genuine point of view. Greenzest has one, and the discipline to hold it.

This is not the end of the story. It looks very much like new chapters will be written.
