We found all of the Tunley Environmental representatives to be extremely friendly, helpful and knowledgeable. They provided a high standard of service with plenty of advice and support, including regular meetings to update on progress and present findings. We look forward to working with Tunley Environmental again on future projects.

Mary Bellamy

Lead Research Nurse | University Hospitals Birmingham NHS Foundation Trust

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.

Christian Mabey

Managing Director | Optima

I had the pleasure of working with Tunley, and I can’t recommend them enough. As environmental/sustainability consultants, they are incredibly knowledgeable and professional, however what really sets them apart is the personability of each and every one of the team I worked with. Every interaction felt human, with a genuine sense of care and attention to detail. They make you feel like more than just a client – it’s clear they truly value their relationships and are passionate about the work they do. If you're looking for a team that combines expertise with a personal touch, Tunley is the way to go!

Yaya McIrvine

ESG Associate | Westbrook Properties

Tunley Environmental has been great support through our carbon assessments. Tunley completed an embodied carbon report on one of our products, we used the embodied carbon report and submitted to MAKE UK sustainability regional awards and won for our region. Great to be working with Tunley and the team and look forward to reaching our goal of net zero which I know we can with the support and expertise of the team.

Scott Commons

HSQE Manager | PB Design

I would recommend Tunley to anyone with full confidence, they are very knowledgeable in this field, and are very responsive and patient to work with. I felt i started my BCA training with little to no knowledge, Tunley have given me the knowledge and confidence to take on our Business Carbon Assessments annually. Thanks to Tunley for delivering the training and completing our initial carbon assessment to a really high standard.

Ryan Knight

Business Operations Manager | With-You

The project ran seamlessly from carrying out regular communication between key project stakeholders to the speed of the project execution and completion. We would highly recommend Tunley Environmental to companies looking to complete product LCAs.

Keely Warren

Brand & Communications Manager | Tremco

Working with Tunley Environmental to meet the UK Government's PPN requirements 06/21 was a seamless experience. As first-timers in greenhouse gas emissions screening and carbon reduction planning, ARK Group DMCC was initially uncertain about the process.

Edward Bicknell

Head of Logistics & Procurement | ARK LLC

Incredible swift and friendly service with a prompt delivery. I will recommend this company for any future works, its not worth the bother looking around just go with these guys 5*****

Glyn Cooper

Director | Eco Cute

We used Tunley Environmental to help us with out carbon reduction targets, they conducted an embedded carbon report for one of our key ranges and we are now exploring next steps. I would highly recommend them professional, helpful a great company to work with.

Kieron King

Quality Manager | InPress

Stacey and Gareth were excellent in explaining the onboarding process and info gathering, taking much of the worry away from us and produced a really professional report and recommendations for achieving net zero. I would not hesitate to recommend Tunley Environmental to anyone considering starting on their carbon reduction journey.
