“(1) A conditional fee agreement which satisfies all of the conditions applicable to it by virtue of this section shall not be unenforceable by reason only of its being a conditional fee agreement; but (subject to subsection (5)) any other conditional fee agreement shall be unenforceable.

“the amount of the fees which would be payable if it were not a conditional fee agreement is to be increased” are not all of the costs as they were in the “no win no fee agreement”
“In deciding whether a percentage increase is reasonable relevant factors to be taken into account may include- (a) the risk that the circumstances in which the costs, fees or expenses would be payable might or might not occur...”
“the amount by which the amount of the fees payable only in specified circumstances is to be increased”
