Our Team (MEP)

Our team specialises in the delivery of building services, energy and sustainability services. We deliver M&E engineering design solutions from the initial feasibility stages through detailed design and on to construction, handover and post-occupancy. 

We offer a fresh approach to M&E, getting involved early, working collaboratively with the design team, highlighting options, guiding design development and using our expertise to help clients make key decisions – an approach that always results in a building that delivers. Our solutions are tailored to the client – with the simplicity of design often key, but with the ability to deliver bespoke highly technical solutions if required.

We work across all sectors, including commercial, industrial, leisure, retail, manufacturing, logistics, heritage, and residential for end-user clients, investors, developers, architects, project managers or engineer-led project teams. This diversity of workstreams, and the fact that all of our team members work across every sector, means we are constantly cross-pollinating ideas. You can check out MEP’s project portfolio here.
