I work with a specialist will writing firm that does a free review of existing wills and recommend changes - whether you can update the will or better off starting again, for example. They are also STEP qualified (
https://www.step.org/for-the-public). As they are based in York, this keeps the cost down. I'm a qualified financial planner and would meet you first to answer questions you have etc. before handing over to them. Feel free to PM me if you'd like to find out more information.
For anyone with a new will who wants to meet face-to-face throughout the will writing process then I'd recommend Anna Lochhead at Jamieson Alexander. She's a lovely person and experienced in this area. Her direct line is 0330 0947 390.
