Build a house deposit saving plan you can track

Help me build a house deposit saving plan.

Target deposit: [amount or percent of a price band]
When I'd like to buy: [year]
Already saved: [amount]
What I can save monthly: [amount]
Other big costs around buying I know of: [solicitor, survey, or "not sure"]

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

Then:
1. Monthly saving needed and the date at my current rate.
2. Ways to close the gap.
3. A simple tracker layout for Google Sheets.
4. Official pages to check for schemes and costs (GOV.UK, MoneyHelper) without saying I qualify.
5. A reminder this is not mortgage advice.

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.
