About Jarnail Bal

I'm a Consultant Neurosurgeon in London and the lead for cerebrovascular (neurovascular) surgery at Barts Health NHS Trust. I help patients facing complex brain, skull base and spinal conditions get expert, compassionate surgical care. My practice has a particular focus on brain aneurysms, arteriovenous malformations (AVMs), cavernous malformations, brain tumours and skull base conditions. I also treat acoustic neuromas, meningiomas, facial pain such as trigeminal neuralgia, hemifacial spasm, head injuries, and adult spinal problems including back, neck and arm pain as well as sciatica.

My medical training began at the University of Manchester, where I studied Medicine. Alongside my degree I undertook an intercalated year in Medical Physics at University College London, graduating with First Class Honours — giving me a strong foundation in the science and technology behind modern neurosurgery. I completed my neurosurgical training in North London before pursuing specialist fellowships in Skull Base Surgery at Barts and Queen's Hospitals, and in Cerebrovascular Surgery at Addenbrooke's Hospital, Cambridge — one of the UK's busiest and most advanced neurovascular centres, where I developed skills in some of the most complex neurosurgical procedures.

I am a Fellow of the Royal College of Surgeons in Neurosurgery (FRCS) and on the GMC Specialist Register (GMC 7074012). Over a 15-year career I have performed more than 1,000 operations.

Throughout my career I have placed patients and their families at the heart of my work. I know that facing a brain, skull base or spinal condition can feel overwhelming, and my priority is to ensure you feel supported, informed and reassured at every step. I believe in open, honest communication — taking the time to explain diagnoses, treatment options and outcomes clearly and compassionately.

My team and I work closely together to provide safe, effective and personalised care. No two patients are the same, so we tailor our approach to your individual needs, whether that involves surgery, monitoring, or working with other specialists for comprehensive care. Alongside my NHS role at Barts Health, I see private patients at HCA facilities, allowing me to provide the same high-quality care in both settings.

Your decision for private care

While I'm proud to lead complex neurosurgical services within the NHS, I recognise the system can sometimes involve waiting times and limited flexibility. Choosing private care lets patients access appointments and treatment more quickly, often at times that suit their personal and family needs.

In a private setting I can spend more time with each patient, offering a more personalised and detailed consultation, and a calmer, more supportive environment at what is often a very stressful time. Importantly, the quality of surgery and clinical expertise remains the same: I bring my experience as a leading NHS consultant directly into private practice.

For many patients, private care offers reassurance through timely access, continuity, and the chance to build a close relationship with their surgeon — while still receiving the highest standards of safety and professionalism.

  • "Mr Bal quite literally saved my life. From the very first consultation he explained everything clearly and made me feel safe at a time when I was terrified. His skill and calm approach gave me complete confidence, and thanks to his care I have been able to return to my family and my normal life. I will always be grateful to him and his team."

    Matthew G - AVM Surgery Patient

  • "When my husband was diagnosed we were overwhelmed and frightened. From the moment we met Mr Bal he gave us hope and reassurance. He guided us through every step with compassion and clarity, and his skill in surgery saved my husband’s life. Thanks to him we still have our family together, and I will always be deeply grateful for the care he gave us."

    Nao G - Wife of Patient

  • "When I was told I had a brain tumour, I was terrified. Meeting Mr Bal changed everything. He explained my options in a way I could understand and treated me with kindness and respect. The surgery was a success and I woke up feeling safe and cared for. Thanks to his skill I have my life back and can look to the future with confidence. I cannot thank him enough."
