OUR HISTORY

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.

2016

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.

2017

‘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.

2018

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.

2019

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.

2020

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.

2021

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.

2022

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.

2023

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.

2024

In 2024, our employment rate increased by 83%, bringing our team to 22 members. Our company turnover rose by 111.8% compared to 2023.

By assessing our impact and the outcomes of our customers' assessments, we track Tunley's contributions to proposed emissions reductions and biodiversity enhancement. To date, we have put forth plans to reduce carbon emissions by 249,278 tCO2e per year—equivalent to the weight of 1,723 blue whales.

On the biodiversity front, we have contributed to a net gain of 26.133 habitats through on-site development, the equivalent of 9.15 football pitches.

2024 was an award-winning year for Tunley. We were honored with the title of "Best Sustainability Consultancy 2024" by SME News at the Northern Enterprise Awards.

With an array of new service launches throughout the year, Tunley is well-positioned to help organisations achieve their net-zero carbon and biodiversity goals
