Private vs NHS Baby Scans
We're a private clinic, but the honest answer is that NHS and private scans serve different purposes, and most parents benefit from using both. Here's the real comparison.
Quick Answer
NHS and private scans are complementary, not competitors. The NHS provides two free scans (12-week dating, 20-week anomaly) which are the diagnostic gold standard for clinical screening. Private scans cost £60–£995 and offer earlier reassurance (from 6 weeks), 4D HD Live bonding, longer appointments, more guest spaces, and same-day or next-day availability, things the NHS isn't designed to deliver. Most parents who book private scans use them alongside their NHS appointments, not instead of them.
Side-by-Side Comparison
Every feature that matters when choosing between NHS and private, from cost and wait times to scan duration and equipment.
| Feature | NHS | Private (Numi Scan) |
|---|---|---|
| Cost to you | Free at point of care (covered by NI / general taxation) | £60 – £995 depending on scan type |
| Standard scans offered | Dating scan (~12 wks), Anomaly scan (~20 wks) | Reassurance, gender, 4D HD Live, growth, NIPT, presentation |
| Earliest scan available | From ~10–14 weeks (dating scan) | From 6 weeks (early reassurance) |
| Wait time for routine appointment | 2–6 weeks typical | Same-day to 1 week at most clinics |
| Scan duration | 15–20 minutes | 20–45 minutes depending on package |
| 4D HD Live bonding scans | Not offered | Standard offering at most private clinics |
| Photos / digital images | 1–2 prints, no digital images | Multiple prints, digital images via email/USB |
| Guests allowed | 1 partner only (post-COVID rules vary by trust) | 2–4 family members and children typically welcome |
| Gender determination | Sometimes told at 20-wk anomaly scan; some trusts no longer disclose | Always told (DNA test from 8 wks, ultrasound from 15 wks) |
| NIPT (Down's screening) | Combined test offered as standard; NIPT only after high-chance result | NIPT Test available to anyone from 10 weeks (three tiers: Standard from £265) |
| Equipment | Mix of older and newer machines depending on trust | Latest GE Voluson Expert HD Live, Samsung HERA W10 |
| Sonographer | Experienced and registered, NHS-trained | Experienced and registered (often the same staff working privately) |
| Anomaly screening accuracy | Specialised 20-week anomaly scan is the gold standard | Reassurance scans are not a substitute for the NHS anomaly scan |
| Regulation | NHS Trust + CQC | CQC-regulated clinics only (Numi Scan is CQC-regulated) |
When the NHS Pathway Is All You Need
- ✓ You're a low-risk pregnancy with no concerns or history of loss
- ✓ You're happy waiting until 12 weeks for your first scan
- ✓ You don't want or need 4D HD Live bonding footage
- ✓ Cost is the dominant consideration
- ✓ You're satisfied with 1–2 photos and no digital images
- ✓ You don't mind shorter scan times and limited guest numbers
When Private Genuinely Adds Value
- ✓ You want earlier reassurance (from 6 weeks), common after a previous loss or fertility journey
- ✓ You want a 4D HD Live bonding scan or keepsake imagery
- ✓ You want to know baby's gender earlier than 20 weeks (DNA from 8 wks, scan from 15 wks)
- ✓ You want NIPT screening without waiting for an NHS combined test high-chance result
- ✓ Your NHS wait is too long for the timeframe you need (e.g. growth concerns)
- ✓ You want extended scan time and the family-friendly experience
- ✓ You want to bring more than one guest, including children
- ✓ You want fast access, with same-day or next-day appointments
Wait Times: The Real Difference
This is where the two systems diverge most dramatically. NHS dating scans are typically scheduled at the 12-week mark, but the appointment itself is booked weeks in advance, and if you've had a positive home test at 5 or 6 weeks, you may be waiting six or seven weeks before your first NHS scan. A private 6-week scan can fill that gap if you'd rather not wait.
For most parents that's fine. For others (particularly anyone who has experienced a previous loss, fertility treatment, or simply higher anxiety in early pregnancy), six weeks of uncertainty is hard. A private early pregnancy reassurance scan from 6 weeks gives the same answers (heartbeat, single or multiple, dating) and can be booked within days.
Later in pregnancy, the gap matters too. If your midwife flags a small concern at a routine appointment (baby's growth, position, or fluid level) and the NHS follow-up scan is two weeks away, a private growth and presentation scan can give you an answer the next day. The 36-week milestone guide covers the late-pregnancy private scan window in full detail.
