**Six Heart-Related Conditions UK Drivers Must Declare to DVLA – Or Risk a £1,000 Fine**


UK motorists living with certain heart conditions are being urged to ensure they declare their health status to the Driver and Vehicle Licensing Agency (DVLA), amidst warnings that failing to do so could result in a hefty fine or further legal action. The British Heart Foundation (BHF) has cautioned that while most individuals with cardiac diagnoses can continue to drive, it is essential they are aware of which conditions require notification.
Under current UK law, drivers must report any medical issue that could impair their ability to drive safely or could lead to sudden symptoms such as dizziness, fainting, or blackouts. Failing to disclose such relevant health matters can result in a fine of up to £1,000. In more serious cases, a prosecution can follow if a driver is involved in an accident linked to their condition.

Among the most common cardiac issues that drivers must report are arrhythmias. These irregular heart rhythms, which can cause a person’s heartbeat to become abnormally fast or slow, can interfere with a driver’s ability to control a vehicle. The BHF advises that anyone with an uncontrolled or unexplained arrhythmia, or one that has not been stable for at least four weeks, should immediately inform the DVLA. It is always best, they underline, to consult a doctor who can provide advice tailored to the individual’s circumstances.
Heart failure is another significant condition on the list. For those living with heart failure, symptoms such as shortness of breath, extreme tiredness, or difficulty with physical movement can severely impede safe driving. If these symptoms are present or develop while someone is behind the wheel, the DVLA must be informed, and driving should be avoided until clearance is given by a healthcare professional.
A diagnosis of vascular dementia, a condition caused by impaired blood flow to the brain leading to damage of brain tissue, must also be declared. As this condition can affect mental sharpness and awareness, it poses a clear concern for road safety. UK licensing authorities require anyone diagnosed with vascular dementia to notify the DVLA, which may result in a temporary or permanent driving suspension depending on the severity.
The presence of implanted medical devices is another area of concern. Anyone who has a pacemaker fitted is obliged to notify the DVLA after the procedure, though they need not do so again when the battery is replaced. Typically, driving should be avoided for about a week after fitting or battery replacement, but individual advice from a healthcare provider is recommended.
Similarly, having an implantable cardioverter defibrillator (ICD) means DVLA must be informed. Although notification for standard battery changes is unnecessary, it is crucial to report if the ICD activates – for instance, by delivering a therapeutic shock. In those cases, and for some people receiving an ICD due to high risk of dangerous heart rhythms, a longer break from driving might be necessary.
Beyond these, a history of a stroke or transient ischaemic attack (known as a mini-stroke) can also impact driving privileges. Typically, those who experience such events may need to stop driving for at least a month. While there is no need to declare the incident to the DVLA immediately, continued symptoms after this period must be reported, and returning to driving should only be done after being cleared by a medical professional.
Medical experts continue to stress the importance of full disclosure to both the DVLA and one’s insurers, as changes in health status could affect coverage for car, travel, and life insurance. The list of conditions which require the DVLA to be notified is regularly updated on the official government website, where drivers are encouraged to seek up-to-date information.
Overall, the guidance from the medical and motoring communities is clear: while a diagnosis involving the heart does not necessarily end a person’s driving days, safeguarding public safety and complying with legal requirements is paramount. Anyone uncertain about their obligations is urged to consult their GP or directly contact the DVLA for official advice.
