From humble beginnings, over thirty five years ago, Clarks Vehicle Conversions was founded when Alan Clark, a bench-hand joiner from Doncaster, decided to “go it alone”.

In 1985, Alan began Ply-lining vehicles from a small workshop in the back of a local builders’ merchants. Within a decade, he had grown the company exponentially and was joined in the workshop by his son, Paul Clark and Brett Harrop.

As of today, Paul and Brett are Directors and still as passionate about quality craftsmanship and the continued progression of Clarks as they were when they first started, as such they appointed Darren Lord as Managing Director in 2015 to take the business to the next level.

Clarks continues to grow, develop and invest in technology and its teams, expertly transforming thousands of vehicles every year, all whilst staying dedicated to its roots and values.
