The cranial osteopath we took DD to is Aidan Spencer. He praticises and tutors at the OCC in Wandsworth but we saw him at the Sunflower Centre in Brockley. However, he also practises in Romford which may be easier for you.

We took DD because we asked 'real medical help' (hospital) for advice when she was a day old, only to be told there wasn't a problem (bollocks there wasn't, the birth notes, which we only got when pregnant with DC2 and having to invoke data protection act, local MP, etc after the hospital refused to release them to the consultant obstetrician at DC2?s birth hospital, showed oxygen deprivation... And the problem that they denied!). Aidan correctly identified the issue, told us what he could help with but also diagnosed the problems that osteopathy wouldn't help and told us we'd need GP referral to physio immediately. He gave us some physio exercises to do and further advice, and wrote a note for the GP too, which she found helpful and accurate and acted upon immediately.
Unfortunately by the time that this happened and we got an appointment with 'real medical help', ie the physio, at the hospital, DD was 12w old, the physio said "why did you wait so long? Did you not notice something was seriously wrong? You have left it too late, your daughter will be deformed for life and it will be your fault, your negligence." I was crying so much I couldn't leave the car park to drive home for about 45 mins.
I called Aidan (the "charlatan", apparently ), he reassured me, saw us again immediately, gave me further exercises to do with DD in the meantime and suggested I use my NHS choice rights to ask the GP to transfer DD to physio at a different hospital, which he recommended and with whom he'd worked. This happened, DD had a year of physio, the new physios were brilliant and said that the exercises were spot-on, and that there was definitely hope and I hadn't fucked up DD's life.
All I can say is that if I'd gone with 'real medical help' at the hospital both those occasions, firstly there was no problem and secondly the problem was so big and identified so late that DD wouldn't be able to walk and there was nothing they could do. As it happened, we saw Aidan and DD now has no issues at all. I took DS to see him too, nothing major with him but reflux, tongue tie and feeding issues caused by those two things (muscle tightness, arching, etc) and again Aidan helped significantly and was honest about the extent to which he could manage symptoms but not the cause. The 'real medical help' (another hospital) we got for the tongue tie snip actually recommended cranial osteopathy (and coincidentally, Aidan in particular) immediately after the op but we'd already booked the session with him.
Go for it. Clearly Austenozzy has been lucky enough either to have DC with no problems, or to have access to excellent medical care with no waiting time, and therefore no need to even seek alternatives in the first instance. We probably ended up spending about £200 on DD's treatment. She can walk, has the use of her left arm and a straight spine, as well as a relatively symmetrical face - all things we were told by the first hospital physio were impossible for her. £200 well spent.
