The Transform Cosmetic Surgery Group is advertising a £750 price reduction for patients who go ahead with 'any two surgical procedures' including liposuction and breast enlargements before 31 December.

Other special offers on Transform's website include a prize draw for the chance to win a £500 'wow! party outfit' for women agreeing to a consultation.

The discounted operations have been criticised as unethical by senior surgeons who accuse Transform of encouraging women to undergo combinations of procedures that could greatly increase the risk of complications.

Advertising guidelines drawn up by the private health care sector – and to which Transform is a signatory – ban deadlines on discounts for surgery as well as financial incentives to lure patients to consultations.

The rules are intended to give women breathing space before going in for plastic surgery. However, they are not legally enforceable.

Transform, which practises at more than 60 locations across the UK, appears to be exploiting the Christmas party season to drum up business. Under the heading 'Prepare to dazzle', its website declares: "For a limited time only, save on cosmetic surgery with £750 off any two surgical procedures, for example;

Breast enlargement and liposuction; Liposuction and tummy tuck; Face lift and brow lift.
