How to get here from St John’s Wood
St John’s Wood to Harley Street is the easiest cross-park journey in London: one Jubilee stop, or eight minutes down Park Road in the car.
The Tube version barely counts as a journey: St John’s Wood to Baker Street is a single stop, and from Baker Street the clinic is a nine-minute walk, east along Marylebone Road past Madame Tussauds’ queue, then down Harley Street to the Weymouth Street corner.
The school-run version is just as simple: down Wellington Road and Park Road with the park on your left, right onto Marylebone Road, and Harley Street is the third turning, about eight minutes without traffic, with pay-by-phone bays on Weymouth Street when you arrive.
NW8’s bookings look like Regent’s Park’s: pregnancy scans through every trimester, children’s ultrasound with a consultant paediatric radiologist, and parents’ own checks timed to the school day. Saturday mornings are the neighbourhood favourite, scan first, Lord’s or the High Street after.
By Tube: 1 stop, about 15 minutes door to door
Jubilee line to Baker Street, exit to Marylebone Road, walk east past the planetarium dome and turn down Harley Street to number 99 at the Weymouth Street corner.
By car: about 8 minutes
Wellington Road, Park Road, right onto Marylebone Road, then Harley Street. Bays on Weymouth Street and the mews; the clinic is inside the Congestion Charge zone on weekdays.
By taxi: about 8 minutes
From the High Street or Abbey Road, ask for 99 Harley Street at the Weymouth Street corner, usually a £10 fare with a pram in the back.
On foot: about 31 minutes
For the unhurried: down through Regent’s Park via the Broad Walk, out at York Gate, and across Marylebone Road, the prettiest route to a scan in London.
Booking around school or a nap? Call 0203 904 4441, reception times family appointments to the hour that genuinely works, not the one the diary prefers.

Why St John’s Wood comes to us
NW8 raises families, and its scans show it: pregnancies followed from six weeks, babies’ hips checked, children’s tummies and lumps looked at gently, and parents’ own health kept current between school runs. All of it happens one Jubilee stop away, with specialists who do this all day.
Pregnancy, properly followed
Early reassurance to growth and presentation scans with senior obstetric sonographers, evening slots mean working partners make it too.
Children seen by a children’s doctor
A consultant paediatric radiologist scans the under-16s, with longer, gentler appointments and explanations pitched at parent and child alike.
Around NW8’s day
8am before drop-off, Saturday mornings before the High Street fills, and same-day answers, because parental worry does not queue well.
What we scan
Browse by area of the body. Each hub lists every scan we offer, with one fixed price per page.
Searching from NW8: a private pregnancy scan near St John’s Wood, a children’s ultrasound without the hospital trip, a breast check that fits inside school hours? Harley Street Ultrasound Group covers every scan a family needs from one CQC-registered clinic at 99 Harley Street, one Jubilee stop away.
That includes early pregnancy and anomaly scans, growth and presentation scans, children’s ultrasound with a consultant paediatric radiologist, hips, tummies, necks and lumps, plus the adult range: breast and pelvic ultrasound, thyroid and neck scans, abdominal checks and MSK scans for tennis elbows from the club courts.
Everything is consultant-led with fixed prices from £160, most scans take about twenty minutes, and the findings are explained before you leave, with the report on your portal the same day.
What people around St John’s Wood search for
Popular from St John’s Wood
What NW8 books most: one fixed price each, specialists who do this all day.
The St John’s Wood diary is generational: an early pregnancy scan one month, the anomaly scan five months later, a baby hip check the next spring, and somewhere in between, the parents’ own thyroid, breast and knee appointments, usually at 8.15am, before drop-off at one of the schools.
Children’s scans are deliberately unhurried and led by a consultant paediatric radiologist; pregnancy scans welcome partners and siblings. If you are unsure what is needed, a clinician will advise on the phone first, including when the honest answer is “nothing, yet”.
Who scans you
Children are scanned by a consultant paediatric radiologist from UCLH; pregnancy scanning is led by senior obstetric sonographers; and the adult team holds NHS consultant posts across London’s teaching hospitals. Hover over a name for background, NW8 parents always do.

What patients say
“Excellent, quick to book, wonderful Doctor and Nurse, highly recommend. Pay for parking bays in Harley Street.”
“A very easy to use and quick service. Booking was simple and the visit was just as easy, very pleasant welcome on arrival and then scan took place. I was given plenty of information before during and after with good aftercare recommendations. All in all a very good experience.”
“You get what you pay for! Zero waiting times, lovely staff who all put me at ease and peace of mind. Worth every penny!”
Questions, answered
Anything else? Call 0203 904 4441, a real person answers, and a clinician can call you back.
One Jubilee stop to Baker Street and a nine-minute walk east along Marylebone Road, down Harley Street to number 99 at the Weymouth Street corner, about fifteen minutes door to door. Driving takes eight via Park Road, with bays on Weymouth Street.
The pretty option: down through Regent’s Park’s Broad Walk, out at York Gate, thirty-one minutes of the best pram route in London.
Yes: NW8 rarely arrives solo, and the clinic is built for it: prams come in, scan rooms fit them beside the couch, and reception has seen every version of the double-drop-off morning.
For your own longer scans, a second adult beats a bored four-year-old, but nobody will blink either way.
A consultant paediatric radiologist: children’s imaging is his entire specialty, from newborn hips to teenagers’ lumps. Appointments run longer, the pace is set by the child, and findings are explained to you both.
It is the standard NW8 expects from its schools, applied to its scans.
No: book any pregnancy scan directly, from six-week reassurance to growth and presentation. Your NHS midwife pathway continues untouched; our same-day report simply travels with you to the next appointment.
Evening and Saturday slots exist so working partners see the screen too, not a photograph of it.
Often, yes, and for the anxious-parent bookings, a child’s lump, early-pregnancy worries, tell reception the situation: those are the appointments the diary bends for.
Call 0203 904 4441 in the morning; same-day slots release through the day.
Monday to Friday 8am to 8pm, Saturday 8am to 6pm. NW8 uses the edges: 8am before drop-off at Arnold House or the American School, after-pick-up slots at four, and Saturday mornings before the High Street brunch rush.
Evening appointments carry the working parents’ pregnancy scans.
Yes, by local standards: pay-by-phone bays on Weymouth Street and the mews around the clinic, the Q-Park a few minutes away, and an eight-minute drive home afterwards. Weekday trips sit inside the Congestion Charge zone; Saturdays don’t.
Honestly, with one child the Jubilee hop is easier; with two, the car earns its keep.
No: one clinic, at 99 Harley Street, one stop away. Concentrating the paediatric radiologist, the obstetric sonographers and the equipment at a single address is precisely what keeps the standard consistent for every family, every visit.
The High Street does many things well; consultant imaging is ours.
Of course: with your consent the report goes to any clinician you name the same day, whether they sit in the Portland, Great Ormond Street or an NHS trust. Many NW8 families run care across several institutions; we are used to being the fast imaging piece in that machine.
Bring the request letter if there is one; a name is enough if there isn’t.
You hear it first from the consultant in the room, in plain language, with the difference between “normal variant”, “watch” and “needs follow-up” made explicit. The written report goes to your portal the same day, with a referral letter to the right paediatric service where needed.
Most children’s scans end in reassurance, and that is delivered just as clearly.
Findings are explained during the appointment, for children, at child height too, and the written consultant report is on your secure portal the same day.
Anything needing action leaves with a plan attached: who, what, and how soon.
Fixed, published prices: early pregnancy scans from £160, most diagnostic ultrasounds £250–£350, children’s scans priced per study on their pages, always including the specialist’s time and the written report.
All major insurers are welcome; bring your authorisation number when you book.
We ask you to book first, even if that is a phone call from St John’s Wood ten minutes before you set off: it means a consultant and a room are ready for you rather than a wait. Same-day slots are released through the morning, so call 0203 904 4441, tell us what you need, and reception will usually find you a time that day.
A consultant radiologist, a doctor who specialises in imaging, or a senior specialist sonographer for pregnancy and gynaecological scans, never a trainee. The person holding the probe explains what they see as they scan, so you leave St John’s Wood-bound already knowing the findings, and the written report is theirs too.
Every scan on this website is at 99 Harley Street, so from St John’s Wood you have one address for pregnancy scans, breast ultrasound and the breast clinic, pelvic and gynaecological scans, thyroid and neck scans, abdominal and kidney scans, joint and sports injury scans, ultrasound-guided injections, and children’s scans. Each has one page and one fixed price; use the search at the top of the page or call us.
NHS waits for a routine ultrasound vary from a few weeks to several months depending on the hospital and the urgency your GP assigns. Here, same-day and next-day appointments are usually available, the findings are explained before you leave, and the report is on your portal the same day. From St John’s Wood that means a worry can be answered the day you decide to act on it.
