A private early pregnancy scan is a first-trimester ultrasound that confirms your pregnancy, checks for a heartbeat, dates how many weeks along you are, and rules out complications such as an ectopic pregnancy or twins — usually with your results explained the same day.

Definition
An early pregnancy scan — also called a viability scan or dating scan — is a first-trimester ultrasound examination that confirms your pregnancy, works out how many weeks along you are, checks that the pregnancy is developing normally, and confirms its location inside the uterus. It’s the earliest scan most people in London choose to have, often taken well before the NHS’s routine 12-week dating scan.
| If you’re wondering… | What the scan shows you | When to book |
|---|---|---|
| Am I really pregnant, and is it viable? | Gestational sac, yolk sac, embryo and heartbeat | From around 6 weeks; heartbeat usually visible by 6–7 weeks |
| How many weeks am I, and what’s my due date? | Crown-rump length (CRL) measurement | 6–10 weeks for the most accurate dating |
| Am I having twins? | Confirmation of the number of sacs or embryos | Any time from 6 weeks |
| Could this be an ectopic pregnancy? | Location check — inside the uterus or not | Straight away if you have pain, bleeding or spotting |
| Do I need a referral first? | No GP referral required for a private scan | Same-day or next-day booking, most days |
When and Why We Use Early Pregnancy Scan
Most patients book an early pregnancy scan for one of a few clear reasons. You might simply want to see the pregnancy sac and embryo after a positive home test, or you may be unsure of your dates and want an accurate estimated due date (EDD) before your NHS booking appointment. Bleeding, spotting or pain in early pregnancy is another common trigger, as is wanting reassurance after a previous miscarriage, ectopic pregnancy, or a pregnancy achieved through IVF or other fertility treatment. An early scan also confirms whether you’re carrying twins or more, and helps assess early complications such as a suspected ectopic implantation or early pregnancy loss.
| Your situation | What the scan checks | Why it matters |
|---|---|---|
| Positive pregnancy test | Gestational sac and embryo | Visual confirmation beyond a urine test |
| Unsure of dates | Gestational age via CRL or sac size | An accurate EDD before your NHS booking |
| Spotting, bleeding or pain | Viability and pregnancy location | Rules out miscarriage or ectopic pregnancy |
| After miscarriage, ectopic pregnancy or IVF | Heartbeat and implantation site | Early reassurance when anxiety is highest |
| Suspected multiple pregnancy | Number of sacs or embryos | Confirms twins or more early on |
What the Scan Includes
From around 6 weeks of gestation, the sonographer looks for the gestational sac, yolk sac and embryo, with a heartbeat usually seen a little later, from about 6 to 7 weeks. They measure either the crown-rump length (CRL) or the gestational sac size to estimate gestational age and due date, confirm how many foetuses are present, and check whether the pregnancy is sitting inside the uterus rather than showing signs of an ectopic implantation.
Most appointments are trans-abdominal, and you may be asked to have a full or part-full bladder, which improves image quality at this early stage. If the pregnancy is very early, a transvaginal scan may be offered instead, or as well, for a clearer view. The appointment itself is quick — typically around 15–20 minutes from start to finish.
| Approximate gestation | What’s often visible | What this tells you |
|---|---|---|
| Under 6 weeks | Sac only; heartbeat not yet expected | A follow-up scan may be recommended |
| ~5–6 weeks | Gestational sac, sometimes a yolk sac | Confirms an intrauterine pregnancy has started |
| ~6–7 weeks | Embryo, and often a heartbeat | Reassurance on viability |
| ~7–10 weeks | Clear CRL measurement | The most accurate window for dating |
What to Expect on the Day
You’ll start with registration and a short conversation about your pregnancy history and any symptoms. The clinic environment is designed to feel private and unhurried, with sonographers taking time to explain what they’re doing throughout. Gel is applied to your lower abdomen for the trans-abdominal part of the scan, and the probe is moved gently across your skin; if a transvaginal scan is needed for a clearer picture, this is always explained first and only carried out with your consent.
You’ll be able to see the screen as the scan progresses, and the sonographer will talk you through the findings in plain language rather than clinical shorthand. Before you leave, you’ll receive a written report, and most clinics also provide digital images the same day. If anything unexpected comes up, the sonographer or a consultant will explain what it means and what happens next, including any onward referral.
Who Performs the Scan & Equipment Used
Scans are carried out by HCPC-registered sonographers or consultant radiologists with specific experience in early obstetric imaging — not general-purpose ultrasound staff. The equipment is high-resolution, with both abdominal and transvaginal probes available so the sonographer can choose whichever gives the clearest view for your stage of pregnancy. Machines are serviced regularly and checked against UK professional ultrasound guidelines, so image quality and safety standards stay consistent scan to scan.
Conditions Detected / Diagnostic Value
An early pregnancy scan confirms an embryonic heartbeat and overall viability, measures gestational age accurately enough to set your due date, and detects multiple pregnancies. It also identifies exactly where the pregnancy sits, which is how sonographers rule out an ectopic pregnancy. Where there’s cause for concern, the scan can flag a possible miscarriage, a blighted ovum, or early fetal demise — though it’s worth being clear about what this scan isn’t: it doesn’t replace the detailed anatomical anomaly scan done later in pregnancy. Its role is early assessment and reassurance, not a full structural check.
Safety and Limitations
Ultrasound uses sound waves rather than ionising radiation, so it’s considered safe for both you and your embryo at this stage. That said, a few factors affect how clear the images are — and therefore what the scan can tell you on the day.
| Factor | How it can affect your scan |
|---|---|
| Very early gestation | A heartbeat may not be visible yet if you’re under ~6 weeks |
| Bladder fullness | A too-empty bladder can make early structures harder to see abdominally |
| Body habitus | Higher maternal body mass can reduce image clarity trans-abdominally |
Where a trans-abdominal view isn’t clear enough, a transvaginal scan is often used instead to get a better picture at this early stage. It can feel mildly uncomfortable but is clinically safe when carried out by a trained sonographer, and it’s a solution to the factors above rather than a limitation in itself.
Occasionally, a scan done very early shows no pregnancy sac at all despite a positive test — known as a pregnancy of unknown location (PUL). Rather than simply booking a routine follow-up scan a week later, current UK guidance from NICE recommends blood tests to track your hCG hormone levels over time:
“Take 2 serum hCG measurements as near as possible to 48 hours apart”
This is because a very early normal pregnancy and, rarely, an ectopic pregnancy can look identical on a scan until more information is available — so a PUL result on its own is not a diagnosis, and your clinician will guide you through the next step rather than leave you waiting on an assumption.
A normal early scan is reassuring, but it doesn’t guarantee that no complications will develop later — routine follow-up scans through your pregnancy are still recommended.
Pricing & Booking
Private early pregnancy scans across London are typically priced from around £80 up to £130 or more, depending on how many weeks pregnant you are and which clinic you choose. You don’t need a GP referral to book one, and many clinics — including same-day or next-day availability — take bookings online or by phone. Optional add-ons, such as early gender indication or extra printed images, will usually add to the base price.
| What you’re booking | Typically included | Guide price |
|---|---|---|
| Standard early scan | Viability check, dating, heartbeat | From ~£80 |
| Scan with reassurance follow-up | Two shorter appointments a week or so apart | Higher end of the range |
| Scan plus extra images or add-ons | Printed or digital images beyond the standard set | Base price plus add-on fee |

Our Clinicians & Specialist Team
Our consultant obstetricians and specialist sonographers are trained specifically in early pregnancy imaging, and many bring NHS maternity-unit experience alongside their private practice work. Clear clinical governance is in place, including defined pathways for referring you on to NHS or specialist care if a finding needs further investigation.
Patient Experience
Most patients get their results and images on the same visit, with no lengthy wait for a written report. The environment is designed to be comfortable and unhurried, and you’re welcome to bring a partner or family member for support. Where follow-up is needed — whether a repeat scan or a specialist referral — you’ll leave with clear next steps rather than an open question. Patient feedback consistently highlights the friendly, professional reassurance offered at what can be an anxious early stage.
References & Governance
Our clinic is regulated by the Care Quality Commission (CQC) in England, and our sonographers follow guidance from the British Medical Ultrasound Society alongside professional accreditation standards. An early pregnancy scan complements — but never replaces — your standard NHS antenatal care and scan pathway.
