About us

The Survey Association, known generally as TSA, is the trade body for commercial survey companies in the UK.

The association was formed in 1979 to give a focus for private sector businesses in land and hydrographic survey.  It is important to realise, however, that it is not a regulatory body.

The role of TSA is to promote best practice amongst its members, provide a forum for members for discussion, debate and continuing professional development and, to the wider audience such as engineers and architects, provide guidance on new methods and techniques and a list of suitably qualified and experienced companies.

Today, the association has over 190 companies in membership as full, associate, supplier, affiliate or academic members directly involved in the survey business.

TSA is also heavily involved in lobbying Government and other agencies such as the Environment Agency regarding policies likely to affect or involve the survey industry.

TSA meets regularly with RICS and ICES on a range of issues and has established a group called the SLG, or Survey Liaison Group. This body convenes at regular intervals to examine matters of mutual interest and to ensure that there is little or no duplication of effort by the three bodies.

The Secretariat

TSA has a dedicated Secretariat to look after the day to day running of the association and has seen substantial and sustained growth over recent years.

Rachel Tyrrell

Secretary General

Rachel Tyrrell has been involved full-time with TSA since 1998 and has overseen the tremendous growth of the association in that time. She is responsible for the management of a dedicated team, which is based in both Newark and Worcester.

Rachel works closely with Council to ensure TSA members enjoy an ever growing list of membership benefits and she also represents the association when meeting with key stakeholders in the surveying profession.

She also directly supervises all of TSA’s social media output, website content and on-going PR strategy.

Rory Stanbridge MRICS, FCInstCES


Rory Stanbridge was a director of Photarc Surveys, the company he formed in 1974 and with whom he was employed until 2006. During this period Rory served on TSA Council for more years than he cares to remember and in that time he chaired both the  Finance and PR committees. He also served three years as TSA President from 1999 – 2002. Rory has worked in both the United Kingdom and Zambia as a photogrammetrist, and, in the case of Zambia, a police reservist.

Rory is a fellow of Chartered ICES for whom he serves on the F&GP committee, a fellow of the Photogrammetric Society and a member of the RICS. He served as Secretary General of TSA from July 2006 to April 2019.

Susan Murphy

Office Manager

Susan Murphy has been with TSA since 2010, and just like Rory and Rachel, she lives and breathes TSA.  Her enthusiasm, organisation and communication skills all contribute to the smooth running of the Secretariat and she particularly enjoys working directly with the members.  Susan administers the Technical Committee, which covers Above Ground and Below Ground areas of surveying.

Susan previously worked as Secretary to the Chief Executive of the Holmesdale Building Society in Reigate, Surrey, for 23 years and one of a few societies which still remains mutual today.  She also spent five years in France living the “good life” before moving back to England in 2009.

Laura Lynn

Accounts Manager

Laura is a qualified accountant, having gained AAT Level 4 Diploma in Accounting.  She has extensive experience of working in both private and practice, mostly in a small business environment, and joined the TSA team in October 2015.

Laura has brought an array of new skills and talent to the Secretariat, ensuring the Association continues to be as efficient and as organised as possible particularly with regard to the financial aspect.  She enjoys the unique challenges and opportunities that running a successful trade association brings.

Lucie Evans

Office Assistant

Lucie joined the team in March 2019 in her first office job and brings with her a superb work ethic, which helps the whole Secretariat function smoothly and efficiently.  She has taken on editing and updating of the website, alongside supporting the rest of the team with meeting preparation and organisation and also attending TSA events.

Council members

TSA is governed by an elected Council comprising twelve member companies. The Council is subdivided into four core committees: Public Relations (PR), Membership & Internal Affairs (MIA), Technical and Finance. The role of the Secretariat is to efficiently run the day-to-day operation and liaise with the membership.
