How Mark Lawrence led TClarke to £1bn annual revenue goal

At the end of a tenure as long as Mark Lawrence’s as CEO of TClarke, there are many insights to take from his career.

Mark leaves on a high, passing on the strategic target of £1bn (US$1.3bn) in annual revenues to his successor. It is a realistic goal considering the TClarke order book consists of project values exceeding £50m (US$67m) while the current forward order book has already reached an unprecedented level of more than £1bn (US$1.3bn).

Additionally, as one of Britain’s biggest M&E contractors, the company has achieved record levels of operating profit, which hit £18.7m (US$25m), rising from £15.9m (US$21m) in the prior 15-month period.

The company remains debt-free, closing the year with cash and cash equivalents of over £26m (US$35m), although turnover fell around 5% like-for-like in the year to March 2026.

Mark Lawrence’s hands-on approach

Mark gained a reputation for being a "boots-on-the-ground" CEO.

This approach grew out of his years working his way up the ranks of the company from a young apprentice in 1985 to Electrical Engineer, Technical Director in 1997, Executive Director in 2003 and Managing Director - London Operations in 2007.

In 2010, Mark took on the role of Group Chief Executive, leading the company as a publicly listed business on the London Stock Exchange, and then as a private business 14 years later when Regent Acquisitions acquired it for around £91m (US$122m) in June 2024.

“Mark is a hands-on leader who takes personal accountability for and pride in TClarke’s performance and, ultimately, our client’s satisfaction. Mark regularly walks project sites and gets directly involved with many of our clients, contractors and our supply chain,” says TClarke on its website.

From an external perspective, Mark appeared to support a well-established apprenticeship programme and foster a strong culture in the TClarke workplace.

The latter was exemplified when the company cut no staff and made no changes to business operations post-acquisition.

Navigating the pandemic and beyond

Mark has led TClarke through volatile times such as the pandemic.

In 2020, revenue fell from around £334.6m (US$447m) to around £232m (US$310m) when sites were forced to close, causing a pre-tax loss.

However, it returned to profit for the full year, maintained a positive daily cash balance throughout 2020 and grew its daily order book to a record £456m (US$610m).

Under Mark, the company deployed intelligent systems as part of its engineering project for the 22 Bishopsgate skyscraper in London.

He also diversified TClarke’s work away from London, with projects outside the capital growing from £37m (US$49.5m) in 2022 to £88m (US$118m) in 2023. This included doubling its average Scotland tender size.

Continuing the legacy 

While Mark resigned with immediate effect, his successor, Clive Carr, would have had plenty of time to prepare for his new role, having joined the company in 2009 and worked his way up to Managing Director, Built Environment.

In March 2026, the company announced its goal of achieving £1bn (US$1.3bn) in annual revenues, after it succeeded in scaling up its business by over 50% a few years prior. 

“In setting a target of £1bn (US$1.3bn) annual revenue, we are making a statement to the market about our ongoing headroom to grow and our ability to sustain quality as we do that,” it said in an official statement on its website.

It was only in March 2026 that Clive was appointed to the company’s board along with Managing Director, Data Centres and Infrastructure, Lee Crozier and Chris Harris, Managing Director, UK North.

At the time, Lawrence said: “TClarke has a wealth of exceptional talent. These appointments form part of our long-term succession planning and position TClarke strongly for the next phase of its strategic development as we progress towards our goal of achieving annual revenues of £1 billion.

"Clive, Lee and Chris bring significant leadership experience and deep operational knowledge, further strengthening the Board as we continue to grow the business, while creating exciting opportunities for others across TClarke to develop and progress their careers.”
