Julia Barrett

Chief Sustainability Officer, Group Sustainability

As the Chief Sustainability Officer of our in-house sustainability team, Julia leads on realising Rick Willmott’s belief that Willmott Dixon has a 'purpose beyond profit'.

Whilst great sustainability performance has saved the Willmott Dixon Group over £20m in the last 10 years, Julia is passionate in her belief that a culture of sustainability can add value to customers by encouraging innovative thinking, improving project delivery and enhancing whole life product quality. One benefit of this sustainability mindset is the opportunity for learning and collaboration with our supply chain partners. Another benefit is the £2m+ that we contribute in time and projects through the Willmott Dixon Foundation each year to improve the lives of people who live in the communities in which we work. Julia is passionate about encouraging a wider diversity of people to seek a career in the construction sector; she chairs the company’s Gender Diversity Steering Group and is an Ambassador for Construction News’ Inspire Me Campaign.

Julia represents the sector on various industry and sustainability Groups. Under her leadership Willmott Dixon has received three Queen’s Awards for Enterprise: Sustainable Development (2019 and 2014), Social Mobility (2018) and was crowned Sustainable Company of the Year (2016) by Construction News. On a personal note Julia was delighted to be recognised as edie's Sustainability Leader of the Year (2021), BusinessGreen Leaders’ Sustainability Executive of the Year (2018), and named as Women in Constructions’ Green Leader (2017).

An experienced sustainability professional, Julia is a Chartered Environmentalist, a Chartered Engineer and Fellow of the Institution of Chemical Engineers. She was a senior manager at both Cambridgeshire County Council and the Environment Agency and started her career with ICI in various technical and commercial roles.
