Dr William Beer, CEO



Frank Tunley, Dr Will Beer’s great-grandfather, was a pattern maker for Laycock Engineering in Sheffield. From the 1920s until the 1960s, he worked on a wide range of power transmission and garage equipment products. 

Will and Peter have always been fascinated by engineering and design. For many years, they have repaired and re-built motorcycles and cars in their spare time, and they’re continually looking to create new designs that could improve the world.

Will and Peter’s passion for engineering and their concern for the environment led to the creation of Tunley Engineering. With their deep knowledge and experience in engineering, they saw an opportunity to make a positive impact on the world by helping businesses reduce their carbon emissions. Their vision for a cleaner, more sustainable future inspired them to build a successful carbon reduction business that has since helped numerous clients to achieve their environmental goals.


The early concept of what would later become ‘Tunley Engineering’ began in 2016 by Dr William Beer, who through his Engineering Experience realized, just by improvement of processes you could make long-lasting changes to lead times. Regularly William would complete four hours early morning before work.


Tunley Engineering’ becomes a registered company and William Beer commits fully to building a company. Supporting those that ‘design what they sell’ to improve lead times and processes. In the year 2017, Tunley landed it's first customer.


After great success, Tunley landed it’s first global contract! Going even further and adopting a Cloud-based Business Management System (BMS) in Q3 of 2018. Tunley also achieved ISO9001:2015 in Q4 ensuring its commitment to quality.


After seeing a significant percent turnover growth the company grew by 50% from 2018. Shortly after, the number of positive testimonials began to skyrocket. After numerous assessments we expanded into providing training solutions to engineers. Our company turnover increased by 111% on the previous year.


Like many companies, Covid forced us to rethink how we operate. Tunley was already working 100% remotely so we continued to provide high-quality support without needing to be on-site. Our company turnover increased by 8% on the previous year.


The launch of ‘Engineering a Decarbonized Future’ saw Tunley Engineering’s most ambitious move to date. Assembling a team of market leading carbon experts with a passion to make a difference. 2021 saw Tunley Engineering not only deliver its most impressive growth to date, but help our customers make a positive impact on reducing their carbon emissions. Our company turnover increased by 100% on the previous year.


Over time we have seen substantial growth in our Embodied Carbon Assessments and an increased in re-occurring revenue contracts. Our company turnover increased by 53% on the previous year.


Since starting, 2023 is currently our highest employment year, with 17 members of staff, of which 10 are Scientists. Our company turnover is predicted to increase by 189% on the previous year. In the year 2023, Tunley expanded and Tunley Engineering became Tunley Environmental, covering a more sustainable outlook on the future with services covering environmental and biodiversity needs and requirements.

In November 2023, Tunley introduced three new services under the arm of biodiversity. Biodiversity is becoming ever more apparent in businesses, the need to show what your impact is and what you are doing to show a 10% Net Gain. Our three new services are; Biodiversity Footprint Assessment and Biodiversity Net Gain.


We are exceptionally proud of the work we complete and good it is doing for the World. Here is a snippet of some of the organizations we have helped start their Net Zero journey.


“The COVID-19 pandemic has demonstrated how the unimaginable can change the world overnight. Human-made climate change has the same potential to impact our world and requires the right decisions and urgent action now. Optima Products Ltd has committed to achieving net zero GHG emissions in its own operations by 2035, as a manufacturer this will necessitate significant changes. We have therefore engaged with Tunley Environmental to partner us in delivering this commitment.”

“At Sound United, one of our core values is that 'Our Obligation is Bigger than Us'. When implementing ESG, we needed to understand our baseline for carbon footprint in order to understand how we could reduce our impact on the environment. Tunley Environmental's knowledgeable team of professionals knew what we were looking to do, and worked quickly with our global team to gather and analyse our data. Throughout the process, they were easy to work with and on time on their delivery schedule. I highly recommended Tunley's service.”
