Testimonials

"I would like to thank JustOne for all the time, effort, and commitment they have put in to produce our Beyond Cleaning ESG strategy. I was impressed with the way that our consultant, Lindsey, made herself available throughout the year long planning process, providing advice, guidance, support, and numerous changes to finalise the strategy! JustOne were able to communicate with multiple stakeholders and went above and beyond to meet deadlines and turn things round quickly and make our strategy documents look amazing! We could not have done any of this without JustOne."
Jeff Silver

Head of Sustainability and CSR
DOC Cleaning

“JustOne have been an integral part of our sustainability journey. Whether it be through stakeholder engagement, helping to build Bristol’s Move the Word strategy, reviewing and building supporting documentation, to providing general advice on legislation and good practices, there is yet to be a moment that I have seen anything but the absolute pinnacle of service and support from the team at JustOne. Sustainability can be a daunting task to take on, if I could recommend any company to support you in your sustainability journey it will always be JustOne.”
Dominic Offer

Director, Sustainability & Business Development
Bristol Global Mobility

"We would highly recommend the Just One team, from our experience working with Dave Carlos, Lindsey Matejczyk and the team to help us on the road to developing our sustainability strategy. Our journey started in 2019, shortly after I joined the business, and 3 years on I am proud to testify that our Live Beautiful Strategic Framework is the master reference for the company’s strategy, encompassing our full set of goals, completely integrated, and driving everyone’s objectives across the entire group of 650 employees. Each working group feeds into the steering committee and across to our community groups on each site across the UK. The Just One team is always on hand for advice and to steer us, bringing fresh thinking and updating us with best practice in a participative approach with a collegiate voice. Thank you!"
Lisa Montague

CEO

"Regular Cleaning embarked on our journey to become a “truly sustainable business” in 2021, during this time, JustOne has provided exceptional expert support, advice, guidance, and industry knowledge in bringing to life and capturing our values in our  “Better Places” sustainability strategy. JustOne’s friendly team created an atmosphere of collaboration and understanding that helped us a business realise our potential to achieve our objectives to make a real difference in the areas we live and work in. I cannot recommend them highly enough as I have enjoyed working and learning alongside them during the strategy development and hope this continues in the future."
