5 Best Cardiologist Center in London (2026)

Independently ranked by our review of ratings, reviews and reputation · How we chose

By Elara Kestrel, Health and Medical Expert · ✓ Data verified July 2026 · 8 min read

A racing heart, an unexplained flutter, or just wanting a proper baseline check before it becomes a problem: London has no shortage of private cardiologist centers willing to see you. Patients here have left almost 950 Google reviews across the five practices below, and every single one sits at 4.8 stars or higher, a tight cluster that says more about consistency than any one clinic's marketing. What separates them is scope and setting, not how happy past patients were.

Short answer: Dr Francesco Lo Monaco leads with a perfect 5.0 rating across 366 reviews, the deepest track record of any cardiology practice on this list, known for same-day diagnostics on Harley Street. London Cardiovascular Clinic and The Cardiac Clinic both also hold perfect scores for complex interventional cases and one-stop testing. None of the five publish fixed pricing, so confirm insurance cover before booking beyond an initial consultation.

5.0366 Google reviews

Dr Francesco Lo Monaco is a private cardiologist on Harley Street and founder of the National Heart Clinic, offering same-day diagnostics, preventive cardiology and both in-person and video consultations.

What people praise

  • Reviewers consistently describe him as attentive and willing to explain test results in plain language rather than medical jargon
  • One reviewer credits a weekend home visit and same-day testing with quickly resolving a worrying cardiac episode
  • Patients repeatedly mention feeling genuinely listened to, not rushed through a standard appointment

Worth knowing

  • As a Harley Street specialist practice with same-day diagnostics on offer, expect premium London pricing

London Cardiovascular Clinic-Dr Malik-Private Cardiologist

5.0228 Google reviews

The London Cardiovascular Clinic is Dr Iqbal Malik's private cardiology practice on Welbeck Street, part of the One Welbeck Heart Health group. Dr Malik specialises in structural and interventional cardiology, including PFO closure and complex valve cases, and the clinic offers same-day scans and consultations.

What people praise

  • Reviewers describe successful outcomes in genuinely complex cases, including a valve procedure on an 89-year-old patient other surgeons had turned down
  • Patients repeatedly praise the bedside manner shown to nervous family members, not just the patient themselves
  • The clinic is described as clean, modern and efficiently run from booking through to follow-up

Worth knowing

  • As a specialist in complex interventional cases, this may be more specialist than needed for routine cardiology checks

The Cardiac Clinic

5.0142 Google reviews

The Cardiac Clinic operates from London Bridge Hospital, bringing together a team of consultant cardiologists including Professor Gerald Carr-White and Dr Brian Clapp, covering conditions from heart valve disease to heart failure and high blood pressure. The clinic runs diagnostic tests and consultations on the same site, five days a week.

What people praise

  • Patients travelling long distances for specialist referrals describe the team reducing the number of trips needed, including posting monitoring equipment to patients at home
  • Reviewers consistently name the clinic's private secretaries, including one staff member by name, for making the admin side painless
  • The one-stop model, tests and consultation results on the same visit, comes up repeatedly as a reason patients stay with the clinic long-term

Worth knowing

  • 142 reviews is a smaller sample than the top two practices here, though the pattern is consistently strong

Dr Boon Lim - Consultant Cardiologist London

5.0108 Google reviews

Dr Boon Lim is a consultant cardiologist and electrophysiologist at One Welbeck Heart Health, specialising in atrial fibrillation and cardiac ablation, including newer Pulse Field Ablation techniques. Reviewers describe him as a go-to specialist for persistent AF cases that hadn't responded to earlier treatment elsewhere.

What people praise

  • Patients with long-standing, treatment-resistant atrial fibrillation describe years of improvement after his care, including one patient whose AF had persisted for over a decade before treatment
  • Reviewers consistently describe him as taking time to explain complex procedures like ablation in a way that reduced pre-surgery anxiety
  • Multiple patients specifically mention feeling like they were in expert hands during a genuinely stressful procedure

Worth knowing

  • 108 reviews is a smaller sample than the top three practices on this list
  • This is a specialist practice for electrophysiology and AF; for general cardiology checks, a broader practice may be a better first stop

Heart Health, Welbeck London

4.8105 Google reviews

Heart Health at Welbeck is a private cardiology and vascular centre bringing together dozens of consultants under one roof, including Dr Iqbal Malik and Professor Mark Peters. The centre's own site cites 62 cardiology consultants and more than 350 years of combined experience, with same-day testing and results available.

What people praise

  • Reviewers repeatedly describe a smooth, well-organised experience from arrival through testing to same-day results
  • Patients highlight the range of specialists available, meaning a referral within the centre doesn't mean starting over somewhere new
  • Support staff, including nurses and admin, are consistently praised by name across several reviews

Worth knowing

  • The 4.8 rating includes a slightly higher share of lower-star reviews than the top four practices on this list
  • The most recent detailed reviews are a few months old rather than within the last few weeks, so treat recency as a minor factor here

Health information disclaimer: This directory is informational only and not medical advice. Rankings reflect publicly available Google ratings and review volume, not clinical outcomes. Verify any practitioner’s credentials and registration with the relevant medical board before booking.

How we score these practices

We compared live Google ratings and review counts for private cardiology practices across London, then ranked the field on the star rating, how many reviews back it up, how recently people are still reviewing, and how complete each listing is. No business can pay to change these numbers, and none of the five practices on this page currently hold a paid Featured badge.

What does a private cardiology consultation cost in London? (2026)

None of the five practices on this list publish fixed consultation or procedure pricing online, and cost depends heavily on whether you need a first consultation, a course of diagnostic tests, or an interventional procedure like ablation or valve surgery. Several practices here accept private medical insurance, which is worth checking before you book. For anything beyond an initial consultation, ask for a written estimate covering tests, the procedure itself, and follow-up.

Serving all of London

These five practices are concentrated around Harley Street, Welbeck Street and London Bridge, so central London patients are covered from the City to Marylebone to south of the river.

What to ask before your cardiology consultation

  • Do you accept my private medical insurance, and is pre-authorisation needed?
  • Can tests and the consultation happen on the same day?
  • What’s your specific experience with my condition, not just cardiology generally?
  • What are the risks and recovery time for any procedure being recommended?
  • Will I see the same consultant throughout, or a rotating team?
  • What’s the total estimated cost including tests, procedure and follow-up?

Frequently asked questions

Are these rankings paid?

No. Rankings come from public Google data. A business can pay to be a Featured Partner (badge and top placement), but that never changes another business’s score or position. None of the five practices on this page currently hold a Featured badge.

How did you choose these five practices?

We compared private cardiology practices across London on Google, then ranked the ones with a genuine, ongoing review history on rating, volume, recency and listing completeness.

How often is this page updated?

We refreshed the data behind this page in July 2026 and recheck it periodically as new reviews come in.

Do I need a GP referral to see a private cardiologist?

Not always. Several of these practices accept direct bookings, though your insurer may still require a GP referral for the claim itself. Check with your specific practice and insurer.

What’s the difference between a general cardiologist and an electrophysiologist?

A general cardiologist covers the full range of heart conditions. An electrophysiologist, like Dr Boon Lim on this list, specialises specifically in heart rhythm problems such as atrial fibrillation.

The bottom line

Dr Francesco Lo Monaco combines the highest review volume and a perfect score for general and preventive cardiology. If your case is more specific, structural issues, persistent AF, or you simply want the widest choice of consultants in one place, the other four names here each cover that ground well. Confirm insurance cover before booking anything beyond an initial consultation.
