Home blood pressure monitoring can be one of the most useful health habits you ever build, if you use a validated upper-arm monitor and measure properly.
NICE guidance supports home blood pressure monitoring (HBPM) and sets HBPM targets lower than clinic readings (because home readings tend to be more representative).
This guide gives you:
- the best clinically validated monitors you can buy in the UK
- what to prioritise (and what to ignore)
- the fastest way to avoid inaccurate readings

Quick picks (most people should choose one of these)
Best overall (most users)
OMRON X3 Comfort (upper arm, easy cuff, reliable brand)
Best balance of accuracy features + comfort + usability.
Best budget (still reliable)
OMRON X2 Basic (upper arm, simple, great value)
If you want a no-nonsense device that works without fuss.
Best for large arms / cuff-fit problems
OMRON M3 Comfort (Intelli Wrap cuff 22–42 cm)
Cuff size and fit are a huge cause of wrong readings — this model’s wide cuff range helps.
Best for AF screening / irregular rhythm flagging (advanced)
Microlife BP B6 Connect (AFIBsens, Bluetooth)
If you’re specifically looking for an extra rhythm screen feature.
Best “simple and clinically validated” alternative
A&D UA-651 / UA-611 (upper arm)
Solid, straightforward options often listed among trusted monitors in UK contexts.
The only 3 things that actually matter (ignore everything else)
1) Clinical validation (non-negotiable)
In the UK, the safest shortcut is: choose a monitor that is BIHS-approved / clinically validated.
If a monitor isn’t validated, don’t buy it — even if it has “thousands of reviews”.
2) Upper-arm cuff (prefer this over wrist)
Upper-arm monitors are generally more reliable for home use than wrist monitors unless used extremely carefully. If you do use wrist, it must be positioned at heart level exactly — many people don’t.
3) Correct cuff size (this is where most people fail)
A cuff that’s too small can read falsely high; too large can read falsely low. This isn’t minor — it can change decisions.
Before buying, measure mid-upper arm circumference and match it to the device cuff range.

How to measure BP at home (the NHS method, simplified)
This matters as much as the device.
Do this:
- Sit upright with back supported
- Feet flat on the floor
- Rest arm on a table (relaxed)
- Cuff on bare skin (not over clothes)
- Don’t talk during measurement
- Repeat a second reading after a few minutes
Avoid this before measuring:
- exercise
- caffeine
- smoking
- rushing up stairs
(If you do, your reading can be misleading.)
What numbers should you aim for?
NICE notes that home targets are lower than clinic targets. A common HBPM target is below 135/85 mmHg for many adults under 80 (your clinician may personalise targets).
If your home readings are consistently high, the useful step isn’t panic — it’s:
- confirm correct technique and cuff size
- measure over several days
- share a structured log with your GP/clinic
The Healthiyer recommendation (how to choose in 60 seconds)
If you do nothing else, follow this:
- Choose upper arm + clinically validated
- Choose correct cuff size
- Choose based on your personality:
- “Keep it simple” → OMRON X2 Basic
- “Best all-round” → OMRON X3 Comfort
- “Cuff fit issues / large arms” → OMRON M3 Comfort
- “I will actually use an app” → Microlife B6 Connect
