Decide what to do with a bonus or windfall without wasting it

Help me decide what to do with a bonus or windfall.

Amount: [after any known tax, or "not sure about tax"]
Debts: [list or none]
Emergency fund status: [none / partial / ok]
Goals: [list]
What I'd regret not doing: [optional]

Ask me up to 3 short questions first if anything important is missing. Wait for my answers.

Then:
1. A simple split across buffer, debts, goals and enjoyment, with reasons.
2. A 48-hour rule before any big want purchase.
3. Tax or benefit angles to check on GOV.UK or MoneyHelper if relevant (not a ruling).
4. A one-line plan I can stick on the fridge.

Only use what I've told you, leave blanks for anything I haven't given, and don't invent facts, figures or products. This is help organising my own numbers and wording, not financial advice; point me to MoneyHelper, GOV.UK or Citizens Advice for guidance, and to a free regulated debt adviser if I'm struggling to pay. UK English.
