BBL ban in the UK. Can I get fat transfer to the hip areas only?

Thank you for your question. 
There is a misunderstanding that BBL is banned in the UK but this is not true. Surgery should be done in a licensed facility or hospital by a surgeon with the proper experience and qualification, having explained all the risks and complications. 
The best is to seek the proper advice directly from a plastic surgeon. This is very easy to do these days via video consultation. 

First of all congratulations for achieving such a large weight loss: you should be very proud of yourself.
There is no ban in UK for BBL and the procedure can be performed in London.
In cases of severe skin laxity you will need augmentation of both hips and buttock along with your circumferential body lift, otherwise there will be little/no difference.
This is available in UK.
i wish you the best if luck.

No, fat transfer to the hips will bring out your waist. A BBL is encouraged if you are looking for a more prominent buttock. If you are a good candidate for a Brazilian Butt Lift (BBL), the optimal outcomes are achieved with: 1) use of VASER liposuction to harvest the fat, 2) a closed looped system such as Puregraft to process the fat, and 3) strategic micro-packet transplant technique. These three processes have demonstrated over 95% fat graft take. This means that your results will be stable as long as you maintain your weight. As an official VASER trainer, I am routinely referred unhappy BBL patients. One of the most common reasons for disgruntled BBL patients is that patients are not able to accurately communicate their desired buttocks goals to their surgeons.  A buttocks assessment tool can be an invaluable tool to communicate to your surgeon the exact buttocks size and shape you are desiring. A Skype or FaceTime consultation with a BBL specialist can help you get an accurate recommendation and pricing.

My experience has been that weight-loss patients don’t make particularly good liposuction or fat transfer patients. At least not until the majority of skin laxity has been dealt with properly. Loose skin contribute significantly to body contour. The amount of available host tissue to support the graft often shrink down because the skin has been stretched out. This makes the true thickness of fat in the buttocks very thin which may be insufficient to give a great result. In addition to this skin laxity contributes more to contour than fat distribution.Fat transfer to the hips will give it volume in that area only. Technically speaking adding volume to one area will make the adjacent areas proportionately smaller.Without pictures or an examination we can’t speak specifically if this may be a procedure for you or not. I suggest having multiple in person consultations with experienced board-certified plastic surgeon. For weight loss patients I suggest focusing first on skin procedures as the procedures that will give you the greatest benefit.Best, Mats Hagstrom,MD
