Registered Environmental Technician (REnvTech) is the professional title for environmental technicians. Registered Environmental Technicians come from a broad range of professions across industry, government, education and the public sector. They all have demonstrated they apply sustainable thinking through their working lives and a commitment to environmental best practice.

To gain their registration, individuals have been judged by their peers to demonstrate knowledge and understanding of the environment and sustainable management together with their personal commitment to maintaining the required levels of professionalism and their own competence through continued professional development.

Registration sets REnvTechs apart from others working in their field. It establishes proven knowledge, experience and commitment to professional standards, and enhances career prospects.

Stand out from the crowd

A Registered Environmental Technician (REnvTech) registration demonstrates that an individual, has been judged by their peers, to have the ability to apply sustainable thinking through their working live. This highlights key environmental competences when compared to others in the sector as all Registered Environmental Technicians must be able to demonstrate

  • Evidence of their contribution to sustainability and environmental management
  • Supervisory or technical responsibility
  • Effective communication and interpersonal skills
  • Personal commitment to professional standards, recognising obligations to society, the profession and the environment

The option to use the post-nominal letters "REnvTech" provides a clear way for Registered Environmental Technicians to signal this knowledge and expertise to employers and potential clients.

Showcase continuing commitment to profession

An employer employing a Registered Environmental Technician can have confidence in the environmental competence and professionalism of their employee knowing their employee has committed to a Code of Professional Conduct and the maintenance of their competence through a commitment to continued professional development (CPD). 


Make a difference

Having Registered Environmental Technicians within a business ensures operational teams and the potential leaders of tomorrow help businesses continually make sustainable operational decisions day in day out. This helps to enhance public trust in environmental services and those responsible for environmental related decisions. 


Join the network

Registered Environmental Technicians have the opportunity to join the environmental professional directory on the Society for the Environment website to be available to those looking for experts in their sector, as well as to find relevant contacts to build your network.

  • Invitation to speak at events hosted by the Society, Licensed Bodies and partner organisations
  • Discounted access to a variety of events, conferences and networking opportunities
  • Opportunity to showcase your good practice case studies through the Society website and newsletters

More information


The video below describes more of the benefits to becoming an REnvTech, and provides insight from both an existing REnvTech and a CEnv mentor.


To become a REnvTech, you must be a member of one of the three Licensed Bodies who award it (Nuclear Institute, Institution of Environmental Sciences and Institute of Water).

Registration as a Registered Environmental Technician is open to any who demonstrate the required professional competences and commitment. Individuals generally develop these through a combination of education and work experience.

The required education entails a level of knowledge, understanding and skills equivalent to at least Level 3, with the equivalent level of knowledge determined by the Licensed Body. Typically, an applicant will have the equivalent of at least two years’ full-time relevant work-based practice although this need not be contiguous.

To be considered as relevant, work-based practice must have a direct and distinct environmental focus or context. This may comprise paid employment, voluntary activity, academic work placements or research, but may not include pure educational study.

Experience that develops general professional competences, such as communication and presentation skills, research skills and project management skills may be included at the discretion of the Licensed Body, and in proportion to the REnvTech competences. The relevance of work-based practice should reflect the domain of each individual Licensed Body, and be environmental in nature while clearly reflecting the REnvTech competences listed below.

Finally, in order to be eligible for REnvTech status, a candidate must be willing to comply with the Society’s Code of Professional Conduct, as laid out below in the “How to Apply” section.
