Blood Pressure Checks: Common Myths and What Guidelines Say
Blood Pressure Checks: what people commonly get wrong, set against what published UK guidance says.
It is free, takes two minutes, and detects the largest silent modifiable risk factor there is.
Key takeaways
- Recommended interval: at least every 5 years for adults
- Available free: at most community pharmacies
- Most useful single change: Get it checked at a pharmacy if a GP appointment is difficult.
- Commonest mistake: Assuming feeling well means it is normal.
- See a doctor if any of the signs under "When to speak to a doctor" below apply to you.
What the guidance actually says
Before the corrections, the published figures. Everything below is measured against these.
| Measure | Figure |
|---|---|
| Recommended interval | at least every 5 years for adults |
| Available free | at most community pharmacies |
| Clinic threshold | 140/90mmHg or higher |
| Home threshold | 135/85mmHg or higher |
Where people go wrong
Each of these is common, and each is a mistake in the sense that the guidance says otherwise.
- Assuming feeling well means it is normal
- Judging on a single reading
- Skipping checks because you are young; it is not only an older person's condition
What to do instead
- Get it checked at a pharmacy if a GP appointment is difficult
- Take home readings over several days and record the average
- Use a validated upper-arm monitor
- Know your number and what it means
The part that is genuinely uncertain
Guidance changes, and it changes because evidence does. The figures above reflect current UK guidance from the bodies named at the foot of this page; where those bodies revise their position, theirs is the account to follow rather than this one.

When to speak to a doctor
Seek same-day advice for a reading of 180/120 or higher. Call 999 if very high blood pressure comes with chest pain, severe headache, breathlessness, vision changes, weakness on one side, or difficulty speaking.
Where this comes from
How this page was put together
Every figure, recommendation and warning above is taken from the guidance named in Where this comes from. Nothing on this page is inferred, summarised or generalised beyond what those bodies publish: where they give a number, it is their number, and where they are silent, so are we. Pages are rebuilt whenever the underlying record changes. Sign-off by a named clinician, where it has happened, is shown at the top of the page along with the date.

Always speak to a GP, pharmacist or another qualified health professional before making changes that affect your treatment, and never delay seeking medical advice because of something you have read here.
