Some expectant parents like surprises, and they don't want to know the gender of their unborn baby. Others, however, are inpatient, and they want to know the gender as soon as possible. This scan is not only to identify the gender of your baby but also a mini well-being scan to make sure that everything is in order for extra reassurance

What to bring: photo ID, your booking confirmation, and your insurance details if claiming.

No. You can self-refer and book directly online or by phone. You are welcome to share your report with your GP afterwards.

£235 all-inclusive, with no hidden fees. We accept AXA Health, AXA Global, Healix and WPA, and can provide an itemised invoice for your claim.
How quickly will I get my results?
You receive instant verbal results from your clinician at the end of the appointment, and your written report within 24 hours by secure email.
Can I cancel or reschedule?
Yes — free of charge up to 24 hours before your appointment. Within 24 hours a cancellation fee may apply.
How accurate is a gender scan?
Gender determination by ultrasound is highly accurate from 16 weeks of pregnancy, typically 95–99% accurate when the baby is in a favourable position. If the baby is not in a position that allows clear visualisation, a repeat scan may be recommended.
Is my appointment confidential?
Yes. Appointments and reports are handled in full compliance with UK GDPR and the Data Protection Act 2018, and nothing is shared with your GP or any third party without your written consent.
