If you hold a UK driving licence and develop a health condition — or an existing one gets worse — you may have a legal duty to tell DVLA, even if your renewal isn’t due for years. It’s a rule a lot of drivers don’t realise applies to them until it’s too late, and getting it wrong can mean a £1,000 fine, invalid insurance, or prosecution if you’re involved in an accident.

This guide explains what counts as a notifiable condition, how to report it, and what actually happens to your licence once you do.

What Counts as a “Notifiable” Medical Condition?

A notifiable condition is any medical condition or disability that could affect your ability to drive safely. Importantly, this obligation isn’t limited to a fixed checklist — if a condition could reasonably affect your driving, you’re required to report it and let DVLA make the assessment. Assuming your own condition is “too mild to matter” isn’t a legal defence.

That said, DVLA does maintain a detailed A-Z list of conditions that must always be declared. Broadly, these fall into a few categories:

• Neurological conditions — epilepsy, seizures, blackouts, Parkinson’s disease, multiple sclerosis, stroke or TIA (mini-stroke)
• Heart conditions — arrhythmia, angina, pacemakers, heart attacks or heart failure
• Vision problems — conditions affecting eyesight standards for driving
• Diabetes — particularly if treated with insulin
• Mental health conditions — where they affect concentration, judgement or reaction times
• Sleep disorders — moderate or severe sleep apnoea, or medication causing persistent excessive sleepiness
• Physical disabilities — amputations, chronic pain, or spinal injuries affecting vehicle control
• Alcohol or substance dependence

If you’re unsure whether your condition qualifies, DVLA’s online checking tool will tell you, and your GP can also advise whether your specific diagnosis needs reporting.

Group 1 vs Group 2 Licences: Why It Matters

The standards you’re assessed against depend on what you drive:

• Group 1 covers cars and motorcycles
• Group 2 covers lorries, buses, coaches, taxis, and ambulances

Group 2 medical standards are considerably stricter across almost every condition. A condition that allows a car driver to keep their licence without restriction can still result in revocation for a bus or lorry driver. If you hold a Group 2 licence, don’t assume car-driver guidance applies to you — check the Group 2-specific standards separately.

How to Report a Medical Condition to DVLA

1. Check if it needs reporting. Use DVLA’s online service to search your specific condition and confirm whether it’s notifiable.
2. Complete the relevant form. Depending on the condition, you’ll either fill in a form online or need to request a paper pack (form D1, plus a condition-specific medical questionnaire).
3. Provide medical evidence. The questionnaire allows DVLA’s medical advisers to request further information from your GP or specialist if needed.
4. Wait for an assessment. Most decisions take around six weeks, though complex cases requiring specialist reports or an independent medical examination can take considerably longer. DVLA introduced a new casework system in 2026 aimed at reducing these delays amid a rising volume of complex medical applications.

What Happens After You Report a Condition

Reporting a condition doesn’t automatically mean losing your licence. In most cases, one of the following happens:

• Your licence is confirmed as-is — no further action needed unless your condition changes.
• You’re issued a short-period licence — valid for 1, 2, or 3 years instead of the standard 10, so DVLA can review your fitness to drive periodically.
• Your licence is restricted or coded — for example, requiring specific vehicle adaptations.
• DVLA requests more information — via your GP, a specialist, or an independent examination, before making a decision.
• You’re told to stop driving — if your condition means you no longer meet the required medical standard, though you can reapply once your doctor confirms you’re fit to do so.

What Happens If You Don’t Report a Notifiable Condition

The consequences of staying quiet are more serious than many drivers realise:

• A fine of up to £1,000
• Potential prosecution if you’re in an accident and an unreported condition is found to be a contributing factor
• Invalidated car insurance — insurers can refuse to pay out entirely if a relevant condition wasn’t declared, leaving you personally liable for damages

Doctors aren’t legally required to report a patient to DVLA themselves, but they can do so without your consent if they believe you’re continuing to drive despite being unfit — public safety takes priority over confidentiality in these cases.

FAQs: DVLA Medical Conditions

Will I automatically lose my licence if I report a condition? Not necessarily. Most drivers who report a condition are allowed to keep driving, sometimes with a shorter licence renewal period or minor restrictions.

How long does a DVLA medical assessment take? Standard assessments take around six weeks. Cases needing specialist input can take longer, though DVLA’s 2026 casework system update aims to speed this up.

Do I need to tell my insurer as well as DVLA? Yes. If a condition is notifiable to DVLA, you must also declare it to your car insurer — failing to do so can invalidate your policy even if DVLA has already assessed and approved you.

What if my condition improves — can I get a full licence back? Yes. Once you meet the required medical standard again, you can apply to have your full licence reinstated, usually with supporting evidence from your GP.

Is there a full list of conditions I can check? Yes — DVLA publishes a complete A-Z list of notifiable conditions on GOV.UK, and their online tool lets you check your specific condition directly.

Getting Your Medical Licence Application Right the First Time

Medical licence applications are more likely to get delayed or bounced back than a standard renewal — missing evidence, the wrong form, or an incomplete questionnaire can add weeks to an already lengthy process.
