Why parents choose us
- 01
The right hands
We route you to an accredited fetal-medicine sonographer — the person who scans you and reports the growth, Doppler and biophysical profile.
- 02
Same-day report
Findings are discussed in the room, with a written report and images the same day — MFM referral if anything needs it.
- 03
Independent, and free
We are paid by no clinic, so the recommendation is impartial and costs you nothing — a private scan that complements NHS antenatal care.
Indicative pricing
What a private third-trimester wellbeing scan costs in London.
Indicative ranges across our partner fetal-medicine clinics. Send the details and we quote firm figures across two or three options.

| Urgent same-week wellbeing scan | £350–£650 | Half-day | Same-week |
Prices vary by clinic, whether serial growth follow-up is included, and whether a same-visit fetal-medicine consultation is booked. We come back with a firm quote within one working day.
The problem
NHS antenatal care doesn’t routinely scan for growth after 20 weeks.
Between the anomaly scan and delivery there is often no ultrasound at all. A private third-trimester wellbeing scan closes that gap — reassuring parents-to-be, and flagging small-for-gestational-age or placental insufficiency early enough to change the plan.
-
Worried about reduced movements?
A same-day wellbeing scan alongside your NHS pathway — never instead of it.
-
Small bump, or a previous SGA baby?
A single scan quantifies the growth trajectory; serial scans confirm the pattern.
-
Reassurance before delivery?
Growth, presentation, placenta location and Doppler — the practical planning picture.

What it shows
The eight things a wellbeing scan answers.
Growth, fluid, Doppler and biophysical profile — the four pillars of third-trimester wellbeing, broken into the specific outputs your report will contain.
-
Estimated fetal weight (EFW)
Biometry plotted on a centile chart — the primary output for growth assessment.
-
Amniotic fluid index
Quantifies the liquor volume — a core signal for placental function and fetal wellbeing.
-
Umbilical artery PI
Pulsatility index in the umbilical artery — placental resistance to fetal flow.
-
Middle cerebral artery PI
MCA pulsatility — the fetal cerebral vascular response to any placental compromise.
-
Cerebroplacental ratio
MCA/UA ratio — a sensitive late-pregnancy marker of placental insufficiency.
-
Placenta location
Anterior, posterior, fundal or low — with any praevia or accreta features noted.
-
Fetal presentation
Cephalic, breech or transverse — a practical planning point from 36 weeks onwards.
-
Red flag: reduced CPR + reduced amniotic fluid — MFM referral
A combined pattern that warrants same-day maternal-fetal medicine review.
Care pathways
What the scan can lead to — the eight most common pathways.
From reassurance through to NICU cot planning — the range of downstream care the scan can trigger, always in step with your NHS antenatal team.
-
Reassurance
A normal EFW, Doppler and biophysical profile — the most common outcome, and the point of the scan.
-
Serial growth scans
Two-weekly biometry when a single scan raises a question about the growth trajectory.
-
Induction of labour (SGA / IUGR)
The obstetric response when growth is small-for-gestational-age or the Doppler suggests placental insufficiency at term.
-
Emergency C-section
Reserved for absent or reversed end-diastolic flow, reduced CPR with reduced fluid, or acute fetal compromise.
-
Corticosteroids for lung maturity
A short course before anticipated preterm delivery to accelerate fetal lung maturation.
-
Structured antenatal follow-up
A written plan folded back into your NHS antenatal pathway — never a parallel track.
-
MFM review
Same-day or same-week maternal-fetal medicine opinion when the findings warrant it.
-
Neonatal ICU cot planning
Advance NICU cot planning when preterm or complicated delivery is likely.

Red flags and escalation
The nine findings that change the plan.
The third-trimester wellbeing scan is exceptionally safe — the practical value is knowing which findings need a same-day maternal-fetal medicine response, and which can be watched.
-
Reduced fetal movement
A same-day scan is the right response — reduced movements are never a wait-and-see.
-
SGA / IUGR (EFW < 10th centile)
Small-for-gestational-age or intrauterine growth restriction — the core reason for the wellbeing scan.
-
Absent / reversed end-diastolic flow
The most serious umbilical artery finding — triggers immediate maternal-fetal medicine escalation.
-
Reduced CPR
A reduced cerebroplacental ratio suggests placental insufficiency, even when EFW is preserved.
-
Oligohydramnios
Reduced amniotic fluid — a marker of placental function that changes the delivery plan.
-
Placenta praevia
A low-lying or covering placenta at 32–36 weeks — plans the delivery route.
-
Vasa praevia
Fetal vessels crossing the cervix — a rare but critical finding for planned Caesarean.
-
Post-dates + reduced fluid
A common late-pregnancy pattern that supports induction rather than expectant management.
-
Maternal comorbidity requiring MFM
Hypertension, diabetes, autoimmune disease or prior pregnancy loss — MFM review sits alongside the scan.

Frequently asked
Everything we get asked about third-trimester scans.
Quick answers on timing, cost, safety, the NHS relationship, and what happens if the scan finds a problem.
-
What is a third-trimester wellbeing scan?
A private ultrasound from 28 weeks that assesses fetal growth (estimated fetal weight plotted on a centile chart), amniotic fluid, umbilical artery and middle cerebral artery Doppler, and the biophysical profile. It reassures parents-to-be, complements NHS antenatal care, and flags small-for-gestational-age or intrauterine growth restriction early.
-
When should I have a third-trimester scan?
From 28 weeks onwards. A single wellbeing scan around 32–36 weeks is common; serial growth scans every two weeks are used when there is a specific concern about growth or Doppler indices.
-
How much does a private third-trimester scan cost in London?
A full wellbeing scan (growth, Doppler and biophysical profile) is typically £280–£450 in our network. A growth-only scan is £220–£360. We confirm a firm figure within one working day.
-
Does this replace NHS antenatal care?
No. A private wellbeing scan complements NHS antenatal care — we send the report and images to your NHS team so nothing is duplicated or missed. If the scan finds anything of concern, we help escalate through the NHS pathway.
-
Is a third-trimester ultrasound safe?
Yes. Diagnostic obstetric ultrasound uses sound waves, not radiation, and has an established safety record at any stage of pregnancy when performed by an accredited sonographer to ISUOG and RCOG standards.
-
What happens if the scan finds a problem?
The sonographer explains the finding in the room and issues a same-day written report. If a reduced cerebroplacental ratio, reduced amniotic fluid, absent or reversed end-diastolic flow, or a growth restriction is found, we arrange a same-day maternal-fetal medicine referral and liaise with your NHS antenatal team.

In practice, in London
Where third trimester wellbeing reassurance scan sits in a private London pathway
With third trimester wellbeing reassurance scan, the London question is usually about report turnaround and the radiologist reading it — not whether the scan is available. Public provision for third trimester wellbeing reassurance scan is competent but constrained by capacity. Private London clinics tend to have shorter diaries and longer appointment slots, so you get the same specialists with more time. For people who’ve been going round in circles with primary care, that first proper conversation is often what shifts things.
Once you’re in the private system for third trimester wellbeing reassurance scan, the pace picks up noticeably. Consultant slots run to time, imaging is usually available in the same building or a short walk away, and the report comes back typed and detailed. It’s the coordination that tends to feel different — one person on the other end of the phone, not a switchboard. For third trimester wellbeing reassurance scan specifically, the difference between a routine report and a sub-speciality read is where private care earns its keep.
We’re careful about what a private pathway for third trimester wellbeing reassurance scan can and can’t promise. It can compress a wait, put you in front of a subspecialist quickly, and get a proper report in your hands within a week. It can’t rewrite what the imaging or the bloods say. Setting that expectation up front tends to make the whole experience less stressful.
