CTSI Individual Membership

As a Chartered Institute, our aim is to build an organisation and lead a profession which is both inclusive and representative of the communities we serve. Renowned for our professionalism and commitment, we are here to support our members through these challenging times, while maintaining the public’s trust and respect for the profession. At the same time, we recognise the need to safeguard and encourage the overwhelming majority of honest businesses. And one way we achieve this is through the promotion and delivery of up-to-date education and training.

Individual membership of the Chartered Trading Standards Institute (CTSI) is open to all trading standards professionals, working across both the public and private sectors. Our Affiliate membership is also open to anyone working outside of the trading standards profession who aligns with or has an interest in promoting the objectives of the Institute. Whether you are at the start of your career, or a seasoned professional – working for a local authority, a business, or self-employed – there is a membership category for you.

CTSI Member Categ­ories and Fees

There are five categories of CTSI Membership for individuals – and each has different requirements. If you are unsure which membership category applies to you, please feel free to contact our Member Services team on 01268 582228 or via email [email protected]

Membership Application Process

To join CTSI, you will need to complete a Membership Application form. To maintain our high standards, each completed application also requires a Proposer – who needs to be current members of CTSI. However, please don’t let this particular requirement act as a barrier to your application. If you don’t yet have a Proposer, simply let us know and we will be happy to arrange this for you.  If you are applying for Affiliate Membership the requirement for a proposer is not waived.

The application process itself is simple. Once your completed Membership Application form has been received, an email including all details and a timeline will be sent to you. Then, as soon as your membership has been approved, we will notify you via email. 

Regional CTSI Branches

CTSI operates 13 Regional Branches around the country, defined by local authority boundaries. When you become a member of CTSI, you automatically join your local CTSI Branch. While no Branch Membership fees are charged in the first year of your membership, in subsequent years, any recurring fees for branch membership (if applicable) will be invoiced at the same time as the national Membership Fees, and then refunded directly to your Branch.

CTSI Code of Conduct

In common with most other professional membership bodies, all members of the Chartered Trading Standards Institute (CTSI) are required to abide by our Code of Conduct. CTSI is governed by its regulations which can be found at (link to resource on about us).
