Most airlines, such as StopDelay, work on a “no win, no fee” basis, so they only charge the fee if they win the claim for you. You will not have to pay for their services if they don’t win. This also means there won’t be any upfront payment when you hire them. That said, it is still worth asking firsthand so that you avoid an unpleasant surprise.

This depends on the claim service that you are working with. For instance, while Claimflights only charges a service fee, Flightright, ClaimCompass, and AirHelp also charge a fee for potential legal actions. So, it’s always best to check the company’s terms and conditions or contact them before using their services.
