See your baby's heartbeat, confirm your due date, and check early development. 8-14 weeks. The most reassuring and emotional moment of early pregnancy.
A dating scan is often the first time you'll see your baby on screen and hear their tiny heartbeat. It's one of the most magical, reassuring, and emotional moments of your pregnancy journey.
You've just discovered you're pregnant. Excitement, joy, perhaps some anxiety — it's all completely normal. A dating scan gives you the reassurance you need in those precious early weeks.

You don't have to wait. While the NHS offers a 12-week scan, many expectant mothers choose a private dating scan earlier for reassurance, especially after previous pregnancy loss, IVF, or fertility treatment.

Real reviews from real mums who've had their dating scan with us
"Seeing my baby's heartbeat for the first time was the most emotional moment of my life. I cried happy tears! The sonographer was so lovely and patient, explaining everything on the screen. My partner and I left with printed photos and so much reassurance. Best £99 I've ever spent. Highly recommend for early pregnancy peace of mind."

"After two previous miscarriages, I was so anxious in this pregnancy. I booked a dating scan at 9 weeks and seeing that strong heartbeat was the biggest relief. The sonographer was so understanding of my anxiety and took extra time to reassure me. I'm now 20 weeks and baby is doing great. Thank you Sonoworld for helping me through those scary early weeks."
December 2025
"IVF pregnancy and I couldn't wait for the 12-week NHS scan. Booked privately at 10 weeks and discovered we're having TWINS! The sonographer showed us both heartbeats and explained that they have separate placentas. My husband and I were in shock (happy shock!). The printed photos are now on our fridge. Such a special memory."
January 2026
"I had irregular cycles and no idea when I conceived. The dating scan gave me an accurate due date which was 2 weeks different from my estimate! Super important for planning maternity leave. The scan was quick, professional, and the sonographer made me feel so comfortable. My partner loved seeing our baby too. Great experience."
December 2025
"I had some light bleeding at 11 weeks and was terrified. Sonoworld got me in the same day! Seeing my baby's heartbeat strong and healthy was the most reassuring thing ever. Turned out to be nothing serious. The peace of mind was priceless. The staff were so kind and supportive. Cannot recommend enough for worried mums-to-be."
November 2025
"Beautiful experience! As first-time parents we were nervous and excited. The sonographer talked us through every step, showed us baby's tiny head, body, and heartbeat. We got lovely printed photos to take home and share with family. Made our pregnancy feel so real. Worth every penny for the reassurance and memories. We'll definitely be back for more scans!"

Common questions about dating scans in early pregnancy
A dating scan is typically performed between 8-14 weeks of pregnancy. The ideal time is 10-13 weeks when crown-rump length (CRL) measurements are most accurate for calculating your due date.
If you're unsure of your dates, have irregular cycles, or want early reassurance, we recommend booking as soon as you have a positive pregnancy test (from around 6-7 weeks you can see a heartbeat).
A dating scan shows:
You'll receive printed photos of your baby to take home.
A dating scan appointment takes approximately 20-30 minutes. This includes:
Yes! From around 6 weeks onwards you should see your baby's heartbeat. By 8-10 weeks the heartbeat is clearly visible on screen and can be measured.
Seeing and hearing your baby's heartbeat for the first time is one of the most reassuring and emotional moments of early pregnancy. Many expectant mothers describe it as the moment their pregnancy felt "real."
The normal fetal heart rate in early pregnancy is 110-170 beats per minute (bpm).
A comfortably full bladder is recommended for transabdominal scans (through your tummy). This helps us get clearer images by pushing your uterus up out of your pelvis.
Preparation: Drink 3-4 glasses of water about 1 hour before your appointment. Don't empty your bladder before the scan.
If we can't get clear images abdominally (which can happen in very early pregnancy or if you have a tilted uterus), we may offer a transvaginal scan (internal ultrasound probe) which doesn't require a full bladder and often provides clearer images in early pregnancy.
Yes, absolutely! Your partner is very welcome to join you in the scan room. Sharing the experience of seeing your baby's heartbeat for the first time is a precious moment for both of you.
Many couples say this is when the pregnancy started to feel "real" for the partner too. We encourage you to bring your partner to share in the joy and reassurance.
In most cases, dating scans show healthy, normally developing pregnancies. However, occasionally we detect:
If we detect any concerns, our sonographer will explain clearly what we've seen and provide guidance on next steps. This may include:
We understand how difficult this can be. Our team will provide compassionate support and clear guidance throughout.

No hidden fees. £164 all-inclusive.
Yes, the NHS offers a 12-week dating scan (between 11-14 weeks) as part of routine antenatal care. This is free on the NHS.
However, many women choose a private dating scan earlier (8-11 weeks) because:
A private dating scan does not replace your NHS 12-week scan (which includes nuchal translucency screening). You should still attend your NHS appointment.
