What the NHS Provides

The NHS provides two routine ultrasound scans during pregnancy:
  • The dating scan (12 weeks): Confirms your due date, checks development, and offers combined screening for chromosomal conditions.
  • The anomaly scan (20 weeks): Checks your baby's organs, growth, and development in detail.

These scans are free, performed by qualified NHS sonographers, and clinically focused. The NHS also offers early scans if there's a clinical need — for example, if you have bleeding, pain, or a history of loss.

NHS scans are efficient and thorough, but they can feel rushed. Appointments are typically 15-20 minutes, waiting rooms can be busy, and you may not get much time to enjoy the experience. Photos are usually available for a small fee (£2-£5) but aren't guaranteed.

What Private Scans Offer

Private scan clinics offer a range of scans throughout pregnancy, including:
  • Early reassurance scans (from 6-7 weeks)
  • Dating scans (10-14 weeks)
  • Gender scans (from 16 weeks)
  • 4D bonding scans (from 26 weeks)
  • Growth scans (any time)

Private clinics typically offer:

  • Longer appointment times (30-60 minutes)
  • More photos or digital images included
  • A more relaxed, comfortable environment
  • More flexible about bringing partners and children
  • Evening and weekend appointments
  • Optional extras like heartbeat bears, videos, and printed reports

Prices vary widely, from around £50 for a basic early scan to £200+ for a 4D bonding package.

Key Differences Compared

| Feature | NHS Scan | Private Scan | |---------|----------|--------------| | **Cost** | Free | £50-£200+ | | **Appointment length** | 15-20 minutes | 30-60 minutes | | **Waiting time** | Can be long | Usually minimal | | **Scan photos** | Sometimes (£2-£5) | Usually included | | **Partner attendance** | Usually one person | Often flexible | | **Children welcome** | Varies | Usually yes | | **Clinical focus** | Yes | Less so | | **Screening included** | Yes (NT, combined) | Sometimes extra | | **Referral needed** | Via midwife | Self-referral | | **Evening/weekend** | Rarely | Often |

When to Choose NHS

The NHS scan is the right choice for most women because:
  • It's free: You don't need to pay for clinical scans.
  • It includes screening: The combined test for Down syndrome, Edwards syndrome, and Patau syndrome is included and free.
  • It's clinically rigorous: NHS sonographers are highly trained and work within strict protocols.
  • It's integrated with your care: Results go straight into your maternity notes and are acted on by your midwife.

You should always attend your NHS scans even if you also have private ones. Private scans don't replace the clinical screening the NHS provides.

When to Choose Private

Private scans make sense when:
  • You want reassurance before 12 weeks: The NHS doesn't offer scans before 11 weeks unless there's a clinical reason. A private early scan can give you peace of mind from 7 weeks.
  • You want more time: If the rushed NHS experience leaves you feeling like you didn't get to enjoy the moment, a private scan gives you more time to bond.
  • You want a gender scan: The NHS doesn't routinely tell you the gender before 20 weeks, and even at the anomaly scan, they may not always check. Private gender scans are available from 16 weeks.
  • You want a 4D bonding scan: The NHS doesn't offer these. They're purely for enjoyment and bonding.
  • You want to bring family: Private clinics are generally more flexible about bringing children and other family members.
  • NHS waiting times are long: If your trust is running behind, a private scan can fill the gap.

Can You Have Both?

Yes — absolutely. Many women have their NHS scans for the clinical screening and add a private scan for reassurance or enjoyment. There's no conflict between the two. Just make sure you still attend your NHS appointments, as they're the ones that count for your medical record.

If you have a private scan that shows something concerning, the private clinic will usually advise you to contact your NHS midwife or GP for follow-up. Private scans don't replace NHS care.

Frequently Asked Questions

### Are private scan sonographers as qualified as NHS ones?

Most private sonographers are NHS-trained and many work in both settings. Always check the clinic is registered and the sonographer is qualified — look for HCPC registration and a diagnostic medical ultrasound qualification.

Will a private scan replace my NHS dating scan?

No. A private dating scan won't give you the combined screening results unless you pay extra for NIPT. Always attend your NHS dating scan for the screening, even if you've had a private one.

Can private scans detect problems?

Yes, a diagnostic private scan can detect many issues, but the NHS is responsible for your ongoing care. If a private scan finds a concern, you'll be referred back to the NHS for management.
