We’ve tested blood pressure monitors from brands including iHealth, Nokia and Omron, among others. Here we round up our pick of the very best we’ve found, including some for less than £30.

Our tough testing has uncovered brilliantly accurate Best Buy blood pressure monitors, whether you want an upper arm cuff for using at home or a light and portable wrist cuff.

However, we’ve also found some disastrous Don’t Buy devices which simply aren’t up the job. These inaccurate devices are not only a waste of time and money, they could also cause you unnecessary worry. The second table on this page reveals which devices to avoid.

Best blood pressure monitors we’ve tested


The Omron M2 Basic arm monitor is a budget price for this leading brand, and - as you might expect - it has none of the extras you'd get with pricier blood-pressure monitors. But could this chunky model with its clear display and single-button operation provide the simplicity and accuracy that you're looking for?


The Omron Evolv Automatic is one of the more expensive blood-pressure monitors we've tested, but what do you get for the price? Does it have plenty of useful features, for example, and is it accurate? We put this arm-worn blood-pressure monitor to the test to find out - read on for our full review.


The Boots blood-pressure monitor for your upper arm is cheap, but is it cheerful? We challenged it in our tough accuracy tests to find out whether it's a bargain buy or waste of money. Read our full review to find out how it performed.


The Omron RS2 is compact and light with a hard plastic case that looks perfect for packing in a corner of your suitcase. But can it give you the accuracy that many wrist monitors can't manage? We sent it to our lab to find out.


The Homedics BPA-2000-EU is a mid-priced model, but it's not the lightest upper-arm blood pressure monitor, weighing 353g. Find out where it really struck gold when we put this blood pressure monitor through its paces, which included rigorous accuracy tests.

And here are three blood pressure monitors to avoid

A blood pressure monitor may have plenty of features or a hefty price tag, but that’s no guarantee of performance. In fact, we’ve found some advanced monitors that perform poorly for accuracy. A blood pressure monitor that gets readings wrong is simply a useless device.

Don't Buy blood pressure monitors


Don’t be tempted by the cheap price of this monitor – it will still be a waste of money as the readings are inaccurate.


This is our lowest-scoring blood pressure monitor of 2017. It has plenty of bells and whistles, but it’s a case of features over functionality. Avoid this model.


This is an inaccurate wrist-worn blood pressure monitor – it’s one to swerve.

How much do I need to spend on a blood pressure monitor?

We’ve tested blood pressure monitors that range in price from £15 right up to more than £100, and our tough tests have revealed that price has no correlation to the accuracy of a device.

Paying more for a monitor often means you're getting a wider range of features - such as the facility to memorise your readings for future reference, the ability to date and time-stamp your readings or wireless connectivity. The latter is found on ‘smart’ blood pressure monitors that can send data to your smartphone, although not all are compatible with both Apple and Android devices. This can be a useful way to keep track of readings, especially if you already use health and fitness apps to monitor other aspects of your lifestyle, or as an easy way to share data with others, including your GP.

Although it might sound appealing to buy a blood pressure monitor that includes all the latest bells and whistles, we’ve uncovered some expensive, feature-packed models that scored a measly one star for accuracy, but some brilliantly accurate Best Buys for less than £30. That’s where our reviews can help – don’t waste your money on a monitor that has plenty of features but reports inaccurate blood pressure readings.
