Why drivers choose us

Indicative pricing
What a private D4 medical costs in London.
Indicative ranges across UK private providers.
In short
A same-day D4 in central London: £120–£180, signed on the day, you post to DVLA.
| Service | Indicative range | Typical duration | Turnaround |
|---|---|---|---|
| Standard D4 HGV / PCV medical | £120–£180 | 20–30 min | Signed same day |
| D4 with ECG (age or history) | £180–£250 | 30–45 min | Signed same day |
| Taxi / private hire medical | £90–£150 | 20–30 min | Signed same day |
| Renewal at 45 / 65 / annual over 65 | £120–£180 | 20–30 min | Signed same day |

| Consultation only (advice pre-medical) | £150–£250 | 30 min | Same visit |
Prices vary by clinic, by area of London and by whether an ECG is needed (usually over 45 or with cardiac history). NHS GPs do not usually provide D4s on the NHS.
The problem
The right doctor, the right day, the right paperwork.
Every D4 in the UK is essentially private - your NHS GP is not obliged to sign one. Getting an appointment fast, at a sensible price, with a doctor who knows the DVLA rules is where we help.
-
Not sure you will pass?
Borderline BP, sleep apnoea, diabetes on insulin, a past seizure - we tell you honestly what the DVLA grey book says before you book.
When it helps
When a D4 medical is the right step.
-
First HGV licence application
A D4 medical is required before the DVLA will issue a first Group 2 provisional for LGV (C, C1, C+E) or PCV categories.
-
Renewal at age 45
Group 2 licences must be renewed at 45 with a fresh D4 medical, then every five years to 65.
-
Renewal at 65 or annual after 65
A full D4 at 65 and then annually every year to keep driving HGV or PCV - the DVLA does not waive it.
-
PCV drivers
Bus and coach drivers (D, D1, D+E) need the same Group 2 medical standards as HGV. Same D4 form.
-
Taxi and private hire
Local authorities (TfL and others) require a medical to the DVLA Group 2 standard for taxi and PHV licences.
-
Forklift and industrial licences
Employers often ask for a DVLA-standard medical for forklift, plant and industrial vehicle operators - the D4 covers it.
-
Return to driving after a medical event
After a cardiac event, stroke, seizure, TIA or new diabetes on insulin, a fresh medical is needed before the DVLA restores your Group 2.
-
Red flag: untreated OSA, unstable diabetes, recent seizure
Untreated sleep apnoea, unstable insulin-treated diabetes with hypos, or a recent seizure - the doctor cannot sign until DVLA rules on off-driving periods are met.
What is checked
The eight categories a D4 covers.
What the doctor works through in the room, and the DVLA Group 2 threshold each area is measured against.
-
Vision - Snellen and visual field
Group 2 requires 6/7.5 in the better eye and 6/60 in the worse, plus a horizontal visual field of at least 160°. Glasses or contacts count - bring them.
-
Cardiovascular - BP, ECG when indicated
Blood pressure below 180/100 to pass. ECG required for a first Group 2 medical over 45, and for anyone with cardiac history.
-
Diabetes - HbA1c and hypo history
Insulin-treated Group 2 drivers must meet strict DVLA rules - no severe hypo in the last 12 months, full awareness, and three months of glucose data.
-
Neurological - seizures, stroke, TIA history
Any seizure, stroke or TIA triggers a defined off-driving period per DVLA rules - five years for a single unprovoked seizure at Group 2.
-
Sleep - OSA screening (STOP-BANG)
A STOP-BANG questionnaire and clinical assessment. Untreated moderate or severe OSA fails Group 2 until effectively treated - usually CPAP compliance data.
-
Mental health and psychiatric history
Serious mental illness, psychosis or active suicidal ideation triggers DVLA notification and specific off-driving periods.
-
Alcohol and drug use
History of dependence or misuse triggers abstinence periods before Group 2 can be reissued - typically a year off from persistent misuse, three from dependence.
-
Musculoskeletal - reach and grip
Enough movement and strength in arms, legs and neck to control a commercial vehicle safely - a brief functional check.
Before your medical
What to know before you sit down.
The D4 is a fixed set of DVLA rules - the grey book. The doctor signs against the rules, not around them. What follows is the honest brief on how to pass first time.
-
Bring your D4 form, glasses and medication list
The doctor cannot examine you against a form you do not have. Bring the printed D4, any glasses or contacts, and a full list of everything you take.
-
Expect to fail if BP is too high
Above 180/100 is an automatic fail on the day.
-
Sleep apnoea - CPAP compliance data
If you use CPAP, bring a compliance download from your machine or clinic. DVLA needs evidence of at least four hours a night on most nights.
-
Diabetes - three months of glucose data
Insulin-treated drivers need blood glucose records for the last three months and no severe hypo in the last year. Bring your meter or a printout.
-
Seizures - DVLA off-driving periods
A single unprovoked seizure means five years off Group 2 driving. Established epilepsy needs ten years seizure-free and off anti-epileptics.
-
Alcohol dependence - abstinence periods
Persistent misuse: one year off. Alcohol dependence: three years off, with evidence of controlled drinking or abstinence and normal liver enzymes.
-
The doctor cannot bend the rules
If the DVLA grey book says do not sign, the doctor will not sign - signing against guidance would end their registration. We tell you honestly before you book.
-
Appealing a DVLA refusal
If the DVLA refuses your licence, you can appeal to the magistrates’ court within six months. A consultant report from us often changes the outcome.
-
If you are marked not fit
You still get the paperwork. We help you understand exactly what needs to change - treatment, time, further tests - and re-book once you meet the standard.
Reading your D4 report
Your D4 in four parts. Read the last one first.
Whichever clinic you use, the shape of the report the doctor completes stays the same.
A quiet reminder
DVLA wording is precise and can read coldly - we translate it for you.
If you would like us to walk you through the completed form and any next steps, just ask.
- 01 Header

DVLA D4 medicals are not usually covered by private health insurance - they are self-pay or paid by your employer. We invoice you or your operator directly.
Frequently asked
Quick answers on who signs it, how long it lasts, what it costs and what happens if you do not pass.
-
What is a D4 medical?
A D4 is the DVLA medical examination report signed by a doctor before you can hold a Group 2 driving licence - HGV (LGV), bus or coach (PCV), or a taxi and private-hire licence in most local authority areas. It covers vision, cardiovascular health, diabetes, neurology, sleep, mental health and substance use, all against the DVLA "Assessing fitness to drive" guidance.
-
Who needs a D4 medical?
Anyone applying for a first Group 2 licence, renewing at age 45, renewing again at 65 and then every year after 65, and drivers returning to Group 2 after a medical event such as a cardiac problem, stroke, seizure or new insulin-treated diabetes. Taxi and PHV drivers usually need one at licence issue and renewal too.
-
Can any GP sign my D4 form?
Any GMC-registered doctor can sign a D4 - the DVLA does not require it be your NHS GP. NHS GPs do not usually provide D4s on the NHS, so almost every D4 is signed privately, either by your own GP for a fee or by a doctor at a private clinic that offers same-day appointments.
-
How long is a D4 medical valid?
The medical must be completed within four months of the DVLA receiving your application. If you delay posting your paperwork, the medical can expire and you will need a fresh one.
-
How much does a private D4 medical cost in London?
Prices vary by clinic and area.
-
What happens if I fail the medical?
The doctor cannot sign a D4 that does not meet DVLA standards. You still leave with the form and a clear note of what did not meet the threshold - most commonly blood pressure, vision, untreated sleep apnoea or diabetes control. We help you sort the treatable ones and re-book once you meet the standard.
