piab solicitor fees going up?

I was wondering what might increase these? Originally my solicitor said the cost for application would generally be 2600 + tax unless there was extra work they had to do, what might this include?

She wrote my application, sent a letter requesting liability confirmation and arranged medicals. I paid for my medical.

I got my PIAB judgement now and she wrote to me saying the fees would be 4100 incl tax and to come in for a meeting to discuss whether to accept the piab amount or not.

Before I go I was wondering was that a reasonable amount and what I should ask about, as they didnt say why it had gone up?

PIAB fees do not go up. Your solicitor can charge you whatever he/she likes, but should give you the fees either per case or per hour in advance. Solicitor is not allowed charge a percentage of the award.
