Private Holter Monitor Test in London

A private Holter monitor test in the UK typically costs from about £240 to £900, depending on how many days you record for and whether a cardiologist reviews the recording and writes a report. Hospital and Harley Street clinics are usually at the higher end.

At London Private Ultrasound, Holter monitoring costs £449 for 3 days, £549 for 5 days and £649 for 7 days, with a free ECG, cardiologist review and a written report included. Adding a cardiology consultation and an echocardiogram costs £599, £699 and £799 for the same durations.

Yes. Holter monitoring, also called ambulatory ECG monitoring, is available on the NHS and privately across the UK. On the NHS it usually follows a referral from your GP or a hospital doctor. Privately you can book directly, with no referral.

We fit and report private Holter monitors at two clinics: Central London (27 Welbeck Street, W1G 8EN) and St Albans (54–56 Victoria Street, AL1 3HZ), seven days a week from 9am to 7pm.

For a private test, expect to pay roughly £250 to £800 or more, rising with the length of recording. A fair price includes fitting, the recording, analysis, a cardiologist’s review and a written report you keep.

Before you compare prices, check who reviews the recording (a cardiologist or a technician), whether the report is included, and how long you wait for it. Ours starts at £449 and includes all three, plus a free 12-lead ECG.

Yes. The NHS provides 24-hour, 48-hour and longer ambulatory ECG monitors, but normally only after a GP or hospital referral. Waiting times for the monitor to be fitted, and then for the result, can run to several weeks depending on your area.

If you do not want to wait, you can book privately with no referral. Our monitor is usually fitted within days, and a GMC-registered cardiologist reviews the recording. If your symptoms are severe, such as fainting or chest pain, do not wait for either: see when to seek urgent help.

Our shortest option is 3-day (72-hour) monitoring at £449 with a free ECG. A longer recording gives a much better chance of catching symptoms that come and go, which a single 24-hour window often misses.

If you specifically need a 24-hour ECG, for example because a doctor has asked for one, call 020 7101 3377 and we will advise on the best option. Private 24-hour heart monitor prices elsewhere generally start from about £200 to £250.

London Private Ultrasound fits and reports Holter monitors at two clinics. Central London is at 27 Welbeck Street, W1G 8EN, in the Harley Street Medical District, a short walk from Bond Street, Oxford Circus, Marylebone and Baker Street. St Albans is at 54–56 Victoria Street, AL1 3HZ, near St Albans City station.

Both are open seven days a week, 9am to 7pm. Fitting is usually available within a few days, and no GP referral is needed. Book online or call 020 7101 3377.

Your Holter monitor is fitted in person at one of our two clinics, so a clinician can place the electrodes correctly and check the trace is clean before you leave. You wear it at home and at work for the whole recording, then bring it back. We do not sell Holter monitors, because the recording needs to be analysed and reported by a cardiologist to be useful.

If you cannot travel to either clinic, call 020 7101 3377 and we will tell you what is possible. Personal consumer ECG devices are not a replacement for a reported Holter.

A Holter monitor, also called an ECG Holter or ambulatory ECG, is a small, portable ECG recorder worn on the chest. It records every heartbeat continuously over several days while you carry on with normal life.

It shows your heart rhythm over time and can detect atrial fibrillation, ectopic beats (including supraventricular ectopics, or SVE), supraventricular tachycardia, a slow heart rate, pauses and heart block that a brief resting ECG may miss.

It depends on how often your symptoms happen. Choose 3-day monitoring if palpitations or dizziness occur most days, 5-day if they are less predictable, and 7-day if they are occasional. Seven days is the longest recording we offer.

The longer you record, the higher the chance of capturing an intermittent rhythm problem. If your cardiologist feels you need a longer recording, such as two weeks, they will explain the options. If you are unsure which to pick, call us and we will help you choose.

You can carry on with most normal activity, and you should, because that is what the recording is meant to capture. The main restrictions are keeping the device dry, avoiding anything that could pull the electrodes loose, and keeping the recorder away from strong magnets and electric blankets. It should not be worn for an X-ray or MRI. You can eat and drink normally.

A Holter monitor is painless and low-risk. The usual side effect is mild redness or irritation under the sticky pads, which can occasionally look like a small patch of burn and settles after removal. Tell us in advance if you have an adhesive allergy or sensitive skin.

Most standard Holter recorders are not waterproof, so avoid baths, swimming and soaking the device. You should only shower if you are told your device is water-resistant. Many people have a quick wash and keep the monitor and electrodes dry.

We explain exactly what is safe for the device fitted at your appointment. If an electrode comes loose, call us and we will advise.

Yes, and you should keep it on overnight, because night-time recordings are an important part of the assessment. The recorder is small and light enough to wear in bed. Most people rest it beside them or clip it to nightwear.

Sleeping on your back or side is usually most comfortable and keeps the leads from being pulled. A soft, loose top helps.

The electrodes are placed on the breastbone and rib area, not on the breasts. A wired bra is usually removed while the device is fitted because the underwire can interfere with the trace, but an unwired or sports bra can normally stay on and often helps hold the leads comfortably.

Wear a two-piece outfit, such as a button-down or loose top with separate bottoms, rather than a dress, so the chest is easy to reach and the recorder is easy to hide. Your chest should be clean, dry and shaved so the pads stick well, with no lotion or powder that day.

Once you return the monitor, the recording is downloaded and analysed and a GMC-registered cardiologist reviews it. The written report is typically ready within a few working days, with a GP referral letter included if a finding needs onward review.

SVE stands for supraventricular ectopics, extra heartbeats that start in the upper chambers. A few are very common and usually harmless. An abnormal result simply means the cardiologist saw something to explain or act on, such as atrial fibrillation, pauses or a very fast rhythm. Your report sets out what it means and what to do next.

No to both. A Holter monitor records the heart’s rhythm, not the coronary arteries, so it does not directly show a blockage. If a blocked artery is suspected, a CT coronary angiogram, a stress test or a cardiology consultation is the right next step.

It also does not measure blood pressure, which needs a separate 24-hour ambulatory blood pressure monitor. An echocardiogram checks the structure and pumping of the heart, which is why many people add one, as in our monitoring package with consultation and echo.

A Holter monitor investigates symptoms that come and go. It is not for an emergency. If you have current chest pain, severe breathlessness, a collapse, or pain spreading to the arm or jaw, call 999 or go to A&E straight away.

For palpitations, dizziness or an irregular pulse that settle on their own, a Holter monitor is a sensible next step, and fitting is usually available within days.
