Reassurance Scan: Complete Guide
Waiting for the NHS 12-week scan can feel like a long stretch, especially if you're anxious about early pregnancy or have experienced loss before. A private reassurance scan is one option many women in the UK consider to bridge that gap — here's what to know before booking one.
What a reassurance scan is
A reassurance scan is a private ultrasound, usually offered by independent early pregnancy scanning clinics, aimed at confirming your baby's heartbeat and checking early development. It isn't part of NHS antenatal care and isn't medically necessary for most pregnancies — its purpose is peace of mind rather than diagnosis.
- Typically performed between around 7 and 12 weeks, ahead of the NHS dating scan
- Usually costs somewhere in the region of £60-£150, depending on the clinic and area
- Checks include: confirming a heartbeat, seeing the gestational sac, and measuring the baby's size
What it can and can't tell you
A reassurance scan can confirm viability — that there is a heartbeat and the pregnancy is developing in the uterus as expected for the dates. What it generally can't do is replace the detailed screening built into NHS antenatal care, such as nuchal translucency screening or the anomaly scan, which are timed and structured differently for a specific clinical purpose.
Who tends to find it helpful
Reassurance scans are popular with:
- Women who feel anxious in early pregnancy, particularly after a previous miscarriage or loss
- Anyone who conceived via fertility treatment and wants an earlier check
- Those who simply don't want to wait until 12 weeks for the first look
If you're not feeling particularly anxious and are happy to wait, there's no medical need to book one — the NHS dating scan at around 8-14 weeks will cover the same core checks as standard care.
Choosing a clinic
If you do decide to book one privately, look for a clinic with sonographers who hold recognised ultrasound qualifications, clear information about what's included, and a sensitive approach — particularly important if you're scanning after a previous loss. Many clinics will also flag clearly that this is a reassurance scan only and not a substitute for your NHS antenatal pathway.
Frequently Asked Questions
Is a reassurance scan worth it?
For many women, especially those feeling anxious or who've had a previous loss, yes — seeing and hearing a heartbeat early on can genuinely ease worry. If you're not particularly anxious, it's not medically necessary and you can simply wait for your NHS dating scan. The earliest a heartbeat is reliably visible is usually from around 7-8 weeks.
What does a reassurance scan check?
It typically confirms your baby's heartbeat, the location and size of the gestational sac, and an early measurement of the baby to check growth is roughly on track for your dates. It's a snapshot check rather than the full range of screening covered by your NHS antenatal scans.
Will a reassurance scan replace my NHS 12-week scan?
No. A reassurance scan is a private, additional check and does not replace any part of your NHS antenatal care. You'll still need to attend your NHS booking appointment and dating/screening scan, which include measurements and screening tests that a reassurance scan doesn't cover.
