Our Story

Our Story

RTP Surveyors is a RICS Chartered Building Surveying practice with a long-standing reputation for providing practical, professional advice across Cornwall and Devon.

Formally Richard Thomas Partnership founded in 1986, the practice has grown and evolved over four decades, whilst retaining the values on which it was established: trusted advice, technical expertise and a commitment to providing a high-quality service to our clients.

The practice expanded through Cornwall during the 1990s and became RTP Surveyors Limited in 2011. Our directors, Richard Collett and John Darbyshire, have played an important role in continuing RTP’s development. Richard became a director in 2011, while John joined RTP in 2013 and became a director in 2018.

In 2018, we extended our reach into Devon with a presence in Plymouth and in 2021, we relocated our Cornwall headquarters to Tremough Innovation Centre in Penryn, providing a modern working environment from which we continue to support clients throughout Cornwall and Devon.

Our history is also reflected in the continuity of our team. Several members of staff have been with RTP since its early years, bringing decades of knowledge and experience to the work we do today. Alongside our wider team, this provides a depth of experience that helps us build strong and lasting relationships with our clients.

In 2026, we celebrated 40 years in business. Whilst much has changed since 1986, our commitment to providing trusted, practical advice and exceptional service remains at the heart of everything we do.

Today, RTP Surveyors brings together an experienced team of Building Surveyors and Property Consultants, providing a comprehensive range of surveying, consultancy, design and project management services to private, commercial and public-sector clients.
