Before you can obtain or renew an HGV licence in the UK, you must pass a D4 medical examination. Unlike many NHS services, the D4 medical is not free — you will need to pay for it yourself. This guide explains exactly how much a D4 medical costs in 2026, what the examination involves, and how to find an approved examiner.
How Much Does a D4 Medical Cost?
The cost of a D4 medical examination varies depending on the provider and location. In 2026, you can expect to pay:
| Provider Type | Typical Cost |
|---|---|
| GP surgery | £80–£120 |
| Private medical centre | £50–£100 |
| Specialist HGV medical provider | £60–£90 |
| Occupational health provider | £70–£110 |
The D4 medical is not covered by the NHS. Some employers will reimburse the cost as part of their driver recruitment or retention packages.
What Does the D4 Medical Involve?
The D4 medical examination is a comprehensive assessment of your fitness to drive a large vehicle. It typically takes 30–60 minutes and covers eyesight, blood pressure and pulse, cardiovascular assessment, neurological assessment, diabetes assessment, sleep assessment, mental health, alcohol and substance use, and general physical examination.
When Do You Need a D4 Medical?
You need a D4 medical when applying for your first HGV licence, when renewing your licence (every 5 years up to age 65, annually thereafter), following a notifiable medical condition, or when the DVLA requests one. A D4 medical certificate is valid for 4 months from the date of examination.
How to Find a D4 Medical Provider
Any registered doctor can complete a D4 form. Call your GP surgery to ask if they offer D4 medicals and what they charge. Many private clinics and occupational health providers offer D4 medicals with same-day or next-day appointments. Search online for "D4 medical near me" or "HGV medical near me".
Tips for Passing Your D4 Medical
Bring your glasses or contact lenses if you use them for driving. Avoid alcohol for at least 24 hours before the examination. Bring a list of any medications you are currently taking. Disclose all medical conditions honestly — failure to do so is a criminal offence. If you have a known condition such as high blood pressure or diabetes, ensure it is well-controlled before the examination.
