Collaboration with our customers
We invest in your success and work as your strategic partner. As part of a customer’s organisation, we unlock the value of their estates and buildings. We help you spot opportunities, navigate risks and turn your overheads into assets.
We’re your strategic partner helping you unlock the true value of your built environment. Mitie have achieved the ISO 44001 certification, the International Standard for Collaborative Working, aligning shared values and joint objectives for a seamless partnership.
Using our leading industry knowledge and unmatched knowledge of the shifting regulatory landscape, we’ll help you navigate risks and spot opportunities.
Effective collaborative working
We collaborate with our customers as strategic partners, rather than simply as suppliers.
Collaboration is the golden thread that runs through everything we do – it is key to forming, managing, and sustaining effective business relationships that drive value.
In March 2024, Mitie Group achieved ISO 44001 certification, demonstrating our commitment to collaborative working. This aligns closely with our core value, ‘Our customer’s business is our business,’ and reinforces the importance of building strong, value-driven relationships with our clients and partners.
