A Dating Pregnancy Scan is an ultrasound assessment used to estimate gestational age and establish an estimated due date (EDD). It also documents fetal cardiac activity where appropriate, the number of babies seen and other relevant early-pregnancy findings.

The Dating Scan is £100 at Tunbridge Wells and Orpington and £120 at Canary Wharf.

This service is designed for approximately 11 to 14 weeks of pregnancy. If your dates are uncertain, you can still book and provide your best estimate or known dates in the booking comments.

Dating is based on standard fetal measurements appropriate to gestation. In this stage of pregnancy, crown-rump length is commonly used where technically obtainable, with the measurement interpreted alongside the scan findings and your known dates.

Yes. Fetal cardiac activity is assessed where expected and technically visible for the gestational stage.

Yes. The scan assesses the number of fetuses seen and can document whether the pregnancy appears singleton or multiple where the views are clear.

Yes. The scan includes an ultrasound estimate of gestational age and an estimated due date based on the measurements obtained.

No. This is a dating ultrasound, not a chromosomal screening test. Nuchal translucency assessment and combined screening are separate pathways where available and clinically appropriate.

Placental position may be noted where visible and appropriate, but the primary purpose of this appointment is pregnancy dating and basic wellbeing rather than a detailed placental assessment.

No. A private Dating Scan complements NHS maternity care. Please keep all NHS antenatal, screening and dating appointments that have been offered to you.

Ultrasound dating may differ from dates calculated from the last menstrual period. The result is documented using the fetal measurement obtained at the scan and should be considered alongside your NHS maternity dating pathway.

If you conceived through IVF, provide your embryo-transfer date, embryo age at transfer if known and any fertility-clinic estimated due date. IVF pregnancies are interpreted using treatment dates rather than LMP alone.

You receive a same-day digital report via Medifile, digital ultrasound images and short baby clips where obtainable and recorded.

No. You can self-refer and book directly.

Heavy bleeding, severe or worsening abdominal or pelvic pain, shoulder-tip pain, fainting, collapse, fever or feeling acutely unwell require urgent NHS assessment and should not wait for a private scan.
