Best blood pressure monitors 2026
To find the best blood pressure monitors, we’ve taken more than 1,300 blood pressure readings. This means we can bring you our definitive verdict on the accuracy and ease of use of the most popular and widely available monitors.
Our accuracy tests involve assessing all blood pressure monitors against the AAMI/ISO Universal standard and the British & Irish Hypertension Society (BIHS) criteria.
Each monitor is tested on 15 participants, and all monitors are compared with mercury sphygmomanometer results, which is the current gold standard in blood pressure testing. Only the most accurate models passed both.
We focused on arm cuff blood pressure monitors in this test. Although wrist monitors tend to be lighter and more portable, they're more prone to giving inaccurate readings compared with arm blood pressure monitors, as your wrist isn't naturally at heart height.
How our tests find you the best
We've tested 10 blood pressure monitors
We've assessed arm cuff blood pressure monitors from big brands and at a range of prices to help you find one you can rely on.
Accuracy
Inaccurate readings are dangerous if you're relying on them to warn you about medical issues. Our robust tests separate the bad from the good.
Ease of use
You don't want an uncomfortable monitor that's a pain or overly complicated to use. Especially if you've got to take daily readings with it.
We also test...
How clear the instructions are, how easy it is to set up and how quick it is to use. Plus if there's any extra features or an accompanying app.

Don’t Buy blood pressure monitors
Our tests uncover the best and the worst. If a product performs so poorly that we think you should avoid it, we name it a Don't Buy.
We've tested two blood pressure monitors that are Don't Buys. These may be simple to use or have useful features, but if you can't rely on them to take accurate blood pressure readings, we can't recommend them. The Don't Buy products we found failed to meet the requirements of the British & Irish Hypertension Society (BIHS) criteria and the AAMI/ISO Universal standard. Meaning they failed to accurately measure either systolic or diastolic blood pressure.
To find out which they are, and which blood pressure monitors earned our Best Buy recommendation, log in or join Which?
How we test blood pressure monitors
- Is this monitor accurate? We take multiple readings from a panel of users with different heights, weights, genders and arm sizes. We compare them with a gold-standard reference device, which is clinically validated for accuracy and reliability.
- Is it simple to set up and use? Multiple people use the blood pressure monitor, noting down whether there were any issues or helpful features. For example, how easy is it to position your arm correctly, plus any features you might find annoying or if it has a screen that's easy to read.
- How comfortable is it? We check whether the blood pressure monitor will pinch your arm, pull out any arm hairs or fail to sit well when you're wearing it.
- How fast is it at taking blood pressure readings? We time each blood pressure monitor repeatedly when taking readings, so we can tell you exactly how quick each device is.
We regularly revisit the blood pressure monitors on sale to see if any more popular brands need testing. If there are, we test them.

Are there NHS-approved blood pressure monitors?
When we spoke with the Department of Health and Social Care, it confirmed that the NHS doesn't endorse medical devices.
Our investigation into non-compliant pulse oximeters sold on online marketplaces found uncertified models sold on Amazon, eBay and Wish, falsely claiming that these were endorsed by the NHS. Plenty didn't have the required CE marks to be sold in the UK, too.
Even if there are no definitive 'NHS-approved' blood pressure monitors, there are alternatives that come close. Seek out monitors displaying the British & Irish Hypertension Society (BIHS) logo and CE marking. You could also consult your healthcare provider for recommended blood pressure monitors.
Can you get a free blood pressure monitor from the NHS?
Not any more. In late 2021, the NHS distributed free blood pressure monitors to 220,000 people diagnosed with uncontrolled high blood pressure as part of the Blood Pressure @home initiative.
However, in Somerset, every library is equipped with a couple of monitors available for borrowing. Pharmacies also offer free checks to eligible individuals over the age of 40. Visit this NHS eligibility tool to find a pharmacy near you if you qualify for free blood pressure checks.
Your blood pressure questions answered by an expert
Dr Pauline Swift, chair of Blood Pressure UK, answers your questions about blood pressure monitors
What is a normal blood pressure reading?
A healthy blood pressure reading is generally considered to be around 120/80 mmHg.
- 120 is the systolic pressure (when the heart contracts)
- 80 is the diastolic pressure (when the heart relaxes)
Anything consistently below 135/85 mmHg taken at home is usually considered acceptable in the UK, although elsewhere in the world, readings below 130/80 mmHg are considered appropriate; readings above 140/90 mmHg are typically classed as high blood pressure.
What is the best time of day to check blood pressure?
The ideal times are:
- First thing in the morning, before eating or taking medication.
- Again in the evening, before bed.
For a reliable picture of your blood pressure, it’s best to take two readings each time, a minute apart and repeat this over seven days. Your doctor will usually use the average.
What is the most common mistake when taking blood pressure?
The biggest mistake is not sitting in the right position. Things such as crossed legs, talking, dangling feet or having the cuff at the wrong height can all give inaccurate readings.
How do you correctly take your blood pressure reading?
To get an accurate result:
- Sit quietly for five minutes before measuring
- Sit with your back supported, feet flat on the floor and legs uncrossed
- Rest your arm on a table so the upper arm or wrist cuff is at heart level
- Place the cuff on bare skin, not over clothing
- Don’t talk, move or look at your phone during the reading
- Take two readings at least one minute apart and use the average.
What are the best features to look for in a blood pressure monitor?
The most important thing is accuracy. Look for devices that:
- Are upper-arm monitors (wrist monitors are less reliable).
- Carry recognised validation marks such as those from the British & Irish Hypertension Society (BIHS), the British Heart Foundation or an international validation protocol.
Additional useful features include:
- Irregular heartbeat detector Helpful for picking up early signs of arrhythmia.
- Blood pressure risk indicator Colour-coded scales that help interpret results.
- Memory storage Ideal for tracking readings over time.
- Bluetooth or wi-fi connectivity Convenient if you like storing or sharing readings digitally, but not essential.
Do I need to service my blood pressure monitor?
Home monitors don’t need frequent servicing, but they should be checked for accuracy every one to two years. Some manufacturers offer calibration services.
Alternatively, you can take your monitor to your GP or pharmacy and compare it with their professional device. If a monitor has been dropped, damaged or gives erratic readings, it should be checked sooner.
