The Directors are pleased to present their Strategic Report together with the audited financial statements for the year ended 31 March 2025. Mark Lawrence, Group Chief Executive provided the following business review.

Business review : A record-breaking year

TClarke delivered a record-breaking year, achieving exceptional results across revenue, profit, and cash performance. This success culminated in the company being recognised as the UK’s Number One Engineering Services Contractor* by revenue, supported by a notably strong balance sheet.

Record revenues, debt free and increased profits

• The company reported record revenues of £846.7m in the 15 months to 31 March 2025, an increase of £355.7m on the prior 12 month period.
• The company remains debt free with cash and cash equivalents improving significantly to £40.3m from £17.4m coupled with access to unusedcredit facilities of an additional £30m
• Gross profit in the period increased to £69.0m from £49.5m and operating profit increased to £15.9m from £15.2m.

Successful transition to private ownership

TClarke combines the scale, expertise, and high-quality in-house resources that set us apart in the market. During the year, we successfully transitioned to private ownership, a significant milestone that enhances our strategic agility and positions the business for long-term growth.

Our principal activities mean we remain at the forefront of the Building Services industry. Our innovation and expertise are employed in the design, installation, integration and maintenance of the mechanical and electrical systems and technologies that a 21st century building needs for control, performance and sustainability.

A proud employer of local people across the UK

We currently operate from seventeen locations serving the whole of the UK. We are a proud employer of local people in the towns and cities that we serve.

Whilst we operate in competitive, commercially driven markets throughout the year, we secured and delivered high-quality projects, consistently exceeding client expectations. At the same time, we continued to invest in our people, skills, and capabilities, creating further capacity for sustainable growth.

Strong project mix 

An analysis of our revenues for the year by project value shows that 46% or our order book is made up from projects with a value of £50m+ this is complemented by a balanced healthy mix of projects across various values.

£20m – £50m = 9%

£10m – £20m = 16%

Below £10m = 29%

As at the 31st March, our forward order book stood at £815 million. We continue to adopt a disciplined and selective approach to tendering, choosing not to pursue projects where margins fall below our acceptable thresholds.

TClarke is widely recognised for its leadership in data centres and major commercial developments across London, and we are well positioned to capitalise on significant opportunities in the future years.

Constant focus on ‘contractor of choice’ for all our markets

Our goal is to be the ‘contractor of choice’ in all of our chosen markets, our business is organised  around five well-established market sectors, where we have deep expertise and a strong track record.

Revenue for the period by sector is set out below:

• Engineering Services – £305 million
• Technologies (including Data Centres and Off-Site Manufacturing) – £297 million
• Infrastructure – £152 million
• Residential and Hotels – £46 million
• Facilities Management – £47 million

Strategic balance across markets and sectors

Looking ahead, TClarke’s nationwide network of 17 operating locations enables us effectively serve our clients. We actively manage and balance growth across these sectors, allowing us to capitalise on market opportunities, respond to sector-specific cycles, and maintain a well-controlled risk profile

We will continue to maintain a strong presence in sectors that provide stable, recurring revenues such as in the public sector, while also building on our proven reputation for delivering complex commercial projects, particularly those beyond our traditional London base. We also aim to expand our footprint in the UK’s ‘Golden Triangle’, Oxford, Cambridge, and London, where world-leading research institutions, universities, and global technology companies continue to drive demand for sophisticated engineering solutions.

Strong focus on net-zero

TClarke recognises its role in supporting the UK’s net-zero ambitions. We are embedding low-carbon solutions across our solutions and designs and leveraging our off-site manufacturing capability to reduce emissions, waste, and time on site

Leader in Health, Safety and Wellbeing

The health, safety and wellbeing of all our employees and suppliers is of paramount importance. TClarke has an ‘absolute’ accident reporting regime which ensures that each accident, no matter how apparently small or insignificant, is reported and included in our statistics. We are proud of the culture that we have created and maintained.

Our overarching goal is simple: that everyone involved in our activities, whether on-site or off-site, returns home safe and well.

In the 15 month period, the lost time incident rate in the Group was much improved compared to 2023 at 0.27 (2023 0.33). The number of incidents reported through our absolute reporting system reduced from 73 in 2023 to 65 in 2025. A third of these incidents were when no work activity was being performed.

Fully committed to ‘The TClarke Way’ and our people

TClarke’s long-term success is built on the commitment of our people to the values embodied in The TClarke Way. We actively engage with our workforce to foster a working environment that supports wellbeing, promotes safety, and enhances job satisfaction across all levels of the organisation.

Our people remain central to our success. Through ‘The TClarke Way’, we foster a culture of accountability, continuous development, and mutual respect. We invest in training, apprenticeships, and digital skills to ensure our teams are equipped for the challenges of tomorrow’s built environment.”

Leading in apprenticeships and talent development 

In a sector dogged by skill shortages, our apprenticeship scheme is a cornerstone of TClarke’s talent strategy. We invest in a comprehensive, fully-supported programme, delivered through dedicated training facilities. The scheme consistently exceeds our internal benchmarks for the quality of intake, successful completions, and long-term career progression, ensuring a strong pipeline of future talent.

As ever, it is the collective talent, commitment, and outstanding work of all our people across every role and location that defines the strength of TClarke.

Built on our reputation for high-quality engineering, reliability, and on-time delivery, our brand is both distinctive and trusted. To all our staff and colleagues, thank you. It is your efforts that drive our performance, enable our growth, and give us the confidence to face the future with ambition.

Once again a privately-owned company, with over 136 years of heritage, TClarke is uniquely positioned to lead the next phase of the UK’s engineering services sector’s growth. We combine innovation, financial strength, and operational excellence across a broad portfolio – and critically, we have the skilled resources at scale to deliver.
