Quick Answer: Event Monitor Cost & Purpose
A private cardiac event monitor (event recorder) in the UK typically costs around £250–£500 in 2026 for the device and report, with longer rentals (14–30 days) at the higher end and a cardiologist consultation usually extra (~£250–£350) if you want one. It records your heart rhythm around the time you have symptoms — you press a button when you feel something, and many devices also auto-detect irregularities.
That makes it ideal for intermittent symptoms — palpitations, dizziness or “missed beats” that happen days or weeks apart and are easily missed by a one-off ECG. Most clinics accept self-referral, you can usually book within 2–7 days, and a report follows within a few working days. If your symptoms are daily, a Holter monitor may suit better.
What this guide covers
If you get palpitations or dizziness that come and go, a cardiac event monitor is often the best way to catch what a short ECG misses. This independent 2026 guide explains the cost, how it works and how it compares to a Holter.

Private Event Monitor Cost in the UK (2026)
Prices vary by provider, monitoring duration and whether a consultant review is included. The 2026 picture:
| What you’re paying for | Typical 2026 cost |
|---|---|
| Event monitor device + report (1–2 weeks) | ~£250–£500 |
| Extended monitoring (14–30 days) | higher end / quote |
| Cardiologist consultation (if added) | ~£250–£350 |

Event Monitor vs Holter Monitor: What’s the Difference?
This is the key decision, and it comes down to how often your symptoms happen. Both record your heart’s electrical activity, but over very different timescales.
| Factor | Event Monitor (recorder) | Holter Monitor |
|---|---|---|
| Best for | Infrequent symptoms (days/weeks apart) | Frequent daily symptoms |
| Duration | Days to weeks; user-triggered + auto-detect | 24–72 hours continuous |
| How it records | Captures episodes around symptoms | Continuous snapshot for 1–3 days |
| Comfort | Often smaller patch or handheld device | Wires & chest electrodes for the period |
In short: if your symptoms happen most days, a Holter monitor (24–72h continuous) will likely catch them. If they’re days or weeks apart, an event monitor’s longer window gives a much better chance of recording an episode. Your clinician may also mention a loop recorder for very rare symptoms.

What an Event Recorder Can Detect
- Intermittent arrhythmias such as supraventricular tachycardia (SVT) or paroxysmal atrial fibrillation (AF)
- Pauses or extra beats (ectopics) associated with your symptoms
- Rate/rhythm changes related to exercise, stress or sleep
For background on heart-rhythm symptoms, the NHS guide to palpitations and the British Heart Foundation on arrhythmias are reliable, non-commercial sources.
How the Event Monitor Works (Step by Step)
- Fitting/issue: a patch or handheld device is provided with instructions (fitting takes 15–30 minutes)
- Recording: you press a button during symptoms; many devices also auto-record irregularities
- Return & analysis: the data are downloaded and reviewed by a cardiac physiologist or clinician
- Next steps: your GP or cardiologist uses the report to guide treatment or further tests
Do You Need a Referral?
Many providers accept self-referral for a private event monitor. However, if you’re using insurance, your policy will usually require clinical justification and pre-authorisation (typically a GP or cardiology referral). A referral also helps integrate the results into your wider care plan. See do you need a GP referral for private treatment?
Insurance vs Paying Direct
| Factor | Pay Direct | Health Insurance |
|---|---|---|
| Upfront cost | One-off fee per test | Monthly premium + excess at claim |
| If you need multiple tests | Costs add up quickly | Often better overall value (policy-dependent) |
| Speed | Very fast | Fast once pre-authorised |
| Follow-up pathway | Self-organise consults | Consults/diagnostics may be covered |
Note that self-requested screening may not be covered — insurance typically covers diagnostics following a specialist referral for symptoms. Check whether insurance covers diagnostics and pre-existing conditions.
The bottom line on event monitoring
For palpitations or dizziness that come and go, a private event monitor is the most practical way to catch what a quick ECG misses — from around £250–£500, booked within days, worn for one to four weeks.
But a finding rarely ends the journey — capturing an arrhythmia usually leads to a cardiology review and often further tests (an echo, a stress ECG), where NHS waits can stretch and self-pay costs stack up.
That’s where health insurance can help — if cover is in place beforehand, the whole pathway gets handled quickly. Compare the top healthcare providers free in 60 seconds here and avoid the NHS waiting times.
Frequently Asked Questions — Private Event Monitor UK
How much does a private cardiac event monitor cost in the UK?
In 2026, a private event monitor typically costs around £250–£500 for the device and report, with longer 14–30 day rentals at the higher end. A cardiologist consultation, if you want one, is usually extra at around £250–£350. Always confirm what’s included before booking.
What’s the difference between an event monitor and a Holter monitor?
An event monitor records around the time you have symptoms (you trigger it, and it often auto-detects too) over days to weeks — best for infrequent symptoms. A Holter records continuously for 24–72 hours — best for symptoms that happen most days. Your clinician chooses based on how often your symptoms occur.
Is a private event monitor accurate?
Yes, particularly for intermittent symptoms. Because it monitors over a longer window than a one-off ECG, it has a much better chance of capturing an episode — though, like any test, it can only record what happens while you’re wearing it.
How long do I need to wear it?
Commonly 7–14 days, but it can be shorter or longer (up to around 30 days) depending on how often your symptoms occur and the device type. Less frequent symptoms usually mean a longer monitoring period.
Can I shower while wearing the device?
It depends on the device. Some patch devices are splash-resistant; others must be kept dry. Always follow your clinic’s specific instructions.
Do I need to change my medication during monitoring?
No — don’t change any medicines unless your clinician specifically advises it. The aim is to record your normal heart rhythm during everyday life, including while on your usual medication.
Do I need a referral for a private event monitor?
Many providers accept self-referral for self-pay. If you want to claim on insurance, you’ll usually need a GP or specialist referral and pre-authorisation to confirm the test is clinically justified.
