I acted for a client on a no win, no fee basis after they were injured working as a security guard for a large company. The accident occurred when my client was signing in a visitor near to some security barriers.
Public liability insurance covers businesses when customers visit their premises. For example, if someone visits a shop and has a trip or slip (that wasn’t their fault) they could make a claim against the business owner. This could be a personal injury claim which covers their medical expenses and also any resulting loss of earnings.
