A company calling itself Doctors on Wheels sold medical fitness certificates to thousands of heavy goods vehicle drivers out of the back of vans, Trading Standards has confirmed, after an investigation into what investigators described as a systematic fraud targeting the haulage industry.

The operation priced its tests at just under £60 — deliberately below the market rate charged by registered occupational health providers — and issued certificates that hold no legal standing under DVLA licensing rules.

Drivers who hold a category C or C+E licence are legally required to undergo periodic medical examinations conducted by a registered GP or occupational physician; the checks screen for conditions including epilepsy, uncontrolled diabetes, and significant cardiovascular disease.

Trading Standards did not specify in its published statement how many of the affected drivers are currently operating vehicles on public roads with certificates sourced from the scheme.

The DVLA has not yet confirmed how many licences it intends to review or suspend pending re-examination.

Doctors on Wheels offered its customers a medical. The vans did not come with doctors.
