Sense-check a side income idea before you quit the day job

Help me sense-check a side income idea.

The idea: [what I'd sell or do]
Hours I truly have each week: [number]
Money I could put into it: [amount]
Skills I already have: [list]
Who I think would pay: [customers]

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

Then:
1. A reality check: time, costs, competition, what could go wrong.
2. A two-week test that costs little or nothing.
3. Basic UK tax and admin topics to check on GOV.UK (not a ruling on my status).
4. A go / reshape / drop verdict for now.
5. What I'd need to track if I proceed.

No invented income forecasts. 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.

For GOV.UK guidance on self-employment and reporting income, use web search and name the page you used. If it doesn't search on its own, open View all tools and choose Search.
