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


It's a fairly basic device in terms of features - your readings won't get date and time-stamped, for example, so you'll have to keep a manual record- but you can rely on it to measure your blood pressure accurately.


An expensive device, which logs blood pressure accurately and comes with plenty of extra features. These include Bluetooth connectivity (allowing you to control it from the Omron Connect app on your smartphone, and use the smartphone app to view trends in your blood pressure) and the ability to detect irregular heart beat.


It's a basic model, but, what it does, it does well. It monitors blood pressure accurately, the display is clear and easily readable, and it's easy to attach and remove the cuff.


This device measures blood pressure incredibly accurately - which is unusual for a wrist-based monitor. It has an irregular heartbeat detector, and it's one of the most lightweight blood pressure monitors we've tested (making it easily transportable when you're on holiday) but it's fairly basic in terms of features apart from that.

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.
