Its on the mid to high side BUT, in saying that, in the past most, solicitors were willing to do stuff like EPA's for less than cost, the general view being that the eventual Probate would work it's way back to the office. Most solicitors now find that a lot of work is on a one off basis with less "relationship building" for the long term, especially with private clients. Funnily enough, clients expect an "above and beyond the call of duty" service from a solicitor ( call to the house, make wills in hospitals etc.,etc.) without additional fees payable or any long term commitment to the solicitor. So, solicitors now tend to charge the actual cost of doing particular work.
EPA's are extremely time consuming and tedious to set up, with a myriad of "what could possibly go wrong" issues to deal with. There is also the long term concern of what if it is not acceptable, ultimately, by the Court when it needs to be registered.
