Giving notice to end an engagement
Notice wording that follows the terms of your contract: the clause, the date and the handover. Check the contract and take advice before you send it.
This wording is a starting point, not legal advice. Check your contract before you send it, and take advice if you are unsure.

Do not send this email without doing two things first. Read the termination and renewal clauses in your own letter: the notice period, how notice must be given, the date it must be given by, and what is owed on ending. Then take advice from a lawyer or your accountant, because the wording and timing of notice can matter and this page cannot know your contract.
This email does not withhold any fee, and does not say why you are leaving. Keep it that way. Any disagreement about what is owed is a separate conversation, and the fee disputes page covers it. If a claim is in progress, say what you want to happen to it.
