About Delta-Simons

Our Company

Delta-Simons is a multi-disciplinary environmental and health and safety consultancy providing trusted advice and solutions to ‘Protect People and Planet’ through facilitating sustainable development.

As a national provider with a regional presence, we work with clients from multiple sectors including; industrial, commercial & residential developers, retailers, industrial manufacturers, fund managers, institutional investors, hi-tech companies, the public sector and charitable organisations. For the past 30 years, our team has provided a holistic suite of commercially astute environmental services and advice, designed to mitigate risk to both people and the environment, whilst removing the pain from planning or maintaining buildings and/or assets.

Through our thought leadership activities and shared learning, as well as being a founding member of the Inogen Alliance – a global corporation of consultants that provides worldwide coverage through one point of contact for environmental, health, safety and sustainability solutions for multinational organisations – we understand the importance of knowledge-sharing and storytelling to increase visibility and subsequent action needed to mitigate climate change and contribute towards a positive future for the planet.
