About us

Lithos is managed by its three directors: Mark Perrin, Steve James and Tracy Perrin.

We employ talented and dedicated people who share a passion for what we do. We enhance the skills of all our employees from Board level down, through mentoring, review and on-going training. All our Principal Engineers are Chartered or working towards Chartership.

Our purpose built office is based in Wetherby,  mid-way between Harrogate, Leeds and York. From this base we are able to operate across the UK, although the majority of our projects are associated with sites located in Yorkshire and the North of England.
