How much would would it cost to fix a weak chin (chin implant and neck lipo suction) on average in the UK?

The price of Chin Implant operation depends on several factors such as the difficulty of your case and your request for your operation area.
In my practice, prices for Chin Implant operation reaches from 2250 Euro up to 2450 Euro range, and it also includes the travel package such as accommodation, local transfers, and language assistance. If you want to learn more you can click the link below.

 Hi, I have performed many facial shaping procedures, including Chin Augmentation with dermal fillers or silastic chin implants, for over 30 years.  Non smiling photos of your face from the front and side would help in the evaluation.  When the chin is weak, this creates an imbalance making the nose appear larger, the mid face top heavy, the lower face looks short, de-emphasizes the lips and allows early formation of a "double chin".  
 Proper placement of a silastic chin implant adds forward projection to the chin thereby creating harmony and balance to the lower face.  Using the same incision, liposuction can be performed to reduce the fat and further shape the neck.  Excess skin, from below the chin, can also be removed through the same incision.  
 I have found that placement of a silastic chin implant, through a small curved incision under the chin (also allows excess skin removal) to be very safe, quick, highly effective and far less invasive than a sliding genioplasty (requires extensive tissue dissection, bone cuts and placement of metal screws and plates to secure the cut segments of bone).  I perform chin implant surgery in 30 minutes or less, often using a local anesthetic alone.  
 When consulting with surgeons perhaps ask not only is your chin weak but do they have experience performing chin augmentation?  The attached video shows how I determine whether the chin is weak.  The selection of the proper size, shape and thickness as well as the proper placement of the silastic chin implant are all "key" elements in creating a naturally looking chin.  If too large of an implant is used in a woman, the chin can look relatively masculine.  That's where experience, performing chin implant surgery, comes into play.  The technique used to insert the chin implant is also key, in my humble opinion.  Going through the mouth should be avoided when placing a silastic chin implant as it's associated with many more unwanted side effects. Hope this helps.
