Introduction
If you’re a UK professional driver, you’ve probably heard both terms — HGV Medical and D4 Medical — and wondered, are they different or the same thing? The truth is, in most cases, they refer to the same medical examination.
In this guide, we’ll explain what each term means, clear up common misconceptions, compare costs, and
help you choose the best option in 2025.
What is a D4 Medical?
A D4 Medical is a health assessment required by the DVLA for drivers of Group 2 vehicles (HGVs, buses, coaches, and some taxis/private hire). It is documented on the official D4 form.
Purpose: To ensure the driver is medically fit to operate large vehicles safely.
Key Checks Include:
• Vision test (with or without glasses/contact lenses)
• Blood pressure measurement
• Medical history review
• Physical examination
• Mental health assessment
• Neurological checks
What is an HGV Medical?
An HGV Medical is essentially the same examination as the D4 Medical, but the term “HGV Medical” is used when the medical is being done specifically for an HGV licence application or renewal.
In short:
HGV Medical = D4 Medical for HGV drivers
The same D4 form is completed for submission to the DVLA.
Cost Comparison in 2025
| Type | Typical Cost (Private Clinic) | NHS GP Cost | Notes |
|---|---|---|---|
| D4 Medical | £49.99 – £100 | £150 – £270 | Price includes eye test at most private clinics |
| HGV Medical | £40 – £80 | £150 – £270 | Cheapest at private providers like Driver Medical Test |
Tip: Private clinics are often faster, cheaper, and include the eye test in the price. NHS GPs can be more expensive and slower due to wait times.
