Wellington Place, Leeds
A Comprehensive Suite of Sustainability Services Across a Landmark Urban Development
Mainer Associates has been proud to support the long-term development of Wellington Place - one of the UK’s most ambitious and sustainable urban regeneration projects, in Leeds. Working across multiple buildings including 2, 3, 4, 5, 6, 7 & 8, 9, 11 & 12, and 14 Wellington Place, we’ve delivered a wide range of sustainability services tailored to the specific requirements of each development site.
Through close collaboration with clients including MEPC, HMRC, and project partners such as Wates Construction and Gardiner & Theobald, Mainer Associates has played a key role in helping Wellington Place set new standards for sustainable, healthy, and future-ready workplaces in the UK.
7 & 8 Wellington Place
Mainer Associates was appointed by Wates Construction to deliver BREEAM Refurbishment & Fit-Out consultancy for 7 & 8 Wellington Place - HMRC’s flagship regional hub in Leeds. As part of one of the UK’s largest office pre-lets outside London, the project aimed to transform over 378,000 sq ft of premium office space to meet high sustainability standards.
We worked closely with the delivery team to guide the project through the BREEAM RFO process, successfully achieving a BREEAM ‘Excellent’ rating. Our support included sustainability strategy development, evidence coordination, and ongoing advisory to align with HMRC’s environmental and operational goals.
This modern, energy-efficient workspace now supports over 6,000 civil servants and exemplifies HMRC’s commitment to responsible and future-focused public sector development.
