Hi srw
This would depend upon where the settlement was coming from. The general rule is that any early settlement should provide at least the dividend you originally pledged - but I always try and encourage my clients to provide a "sweetener" to creditors to assure acceptance.
Without knowing the IP fee breakdown in your case, I am struggling to work out an acceptable figure for you, and you should discuss this with your IP in any case, however a figure in the region of £11,000 probably is in the right ball park.
