It wouldn't be unusual that the solicitor holding the will would see a fee for doing so especially if not getting the probate business. Indeed it is likely that he may query why he is not getting the business. Many people get ideas in their head about this solicitor or that solicitor being good or bad, often without good ground for doing so.
The cost of keeping a will can vary but my solicitor held deeds for 10 years until we sold and charged 450 euro plus V.A.T.
