Aggarwal-Shah is the founder and director of PREACH Inclusion (PREACH standing for Promoting Race, Ethnicity and Cultural Heritage – formerly BAME in Property), an organisation that promotes and preaches intersectional inclusion in the built environment. Launched in 2018 as an online networking group, Aggarwal-Shah has since organised in-person networking events with leading built environment companies for thousands of property professionals, grown an extensive social media following and engaged in numerous campaigns, including Race Equality Week, #MyNameIs, South Asian Heritage Month and International Women’s Day. In 2020, in response to the Covid-19 pandemic and the changing nature of the industry, Aggarwal-Shah evolved what was BAME in Property into a company to offer a range of services, including workshops, consultancy, a jobs board and membership packages. Some of her clients include National Grid, Trident Building Consultancy, Montagu Evans, Turley, London Property Alliance and many more. In April 2024, Aggarwal-Shah rebranded her organisation to PREACH Inclusion, a better reflection of how we identify ourselves, what the focus of the organisation has been for a while and where she aims to take it in the future.
