This applies to injury claims only. "Small claims" means that your solicitor cannot get their fees from the opponent.
So you'd either have to find someone who will work for nothing at all, have insurance for legal fees which covers small claims, or do it yourself.
At the moment if you have a non-injury claim for less than £10,000, legal fees can't be recovered. It's de-lawyered small claims which can be a good or bad thing depending upon how complicated your case is or how articulate and organised you are. Plenty of people fall foul of court procedures & end up bogged down. I have had some cases where, thanks to well intentioned but misinformed amateurs, the good points have been overwhelmed by a plethora of really bad ones so that even the good points have become tainted & impossible to get to.
So, only more serious injuries will end up with representation in court.
