UK Budget Guide

A budget is simply a plan for your money — knowing what comes in, what goes out, and making sure the second number doesn't exceed the first. This guide walks you through building one from scratch, even if you've never budgeted before.

Step 1: Work Out Your Monthly Income

Write down every source of money coming in each month. Use your take-home (net) pay — not your salary before tax.

• Employment income (after tax and NI)
• Self-employment income (average it out over 3–6 months)
• Benefits (Universal Credit, Child Benefit, PIP, etc.)
• Tax credits
• Maintenance or child support received
• Rental income
• Any other regular income

Tip: If your income varies, use the lowest month from the past 3 months as your baseline. It's better to budget conservatively and have money left over.

Step 2: List Your Fixed Outgoings

These are expenses that are the same every month and you have little control over in the short term.

• Housing: Rent or mortgage payment
• Council Tax: Check if you qualify for a discount — single person gets 25% off
• Utilities: Gas, electricity, water
• Insurance: Home, car, life, pet
• Loans & finance: Car finance, personal loans, credit card minimums
• Subscriptions: Broadband, phone contract, streaming services
• Childcare
• Pension contributions

Step 3: List Your Variable Outgoings

These change month to month. Look at your last 3 months of bank statements to get realistic averages.

• Groceries and food shopping
• Petrol or public transport
• Eating out and takeaways
• Clothing
• Haircuts and personal care
• Entertainment and hobbies
• Kids' activities and school costs
• Gifts and occasions

Don't forget irregular expenses. MOT, car service, annual subscriptions, Christmas, birthdays — divide their annual cost by 12 and set that aside monthly so they never catch you off guard.

Step 4: The 50/30/20 Rule (A Simple Framework)

If you're not sure how to divide your income, the 50/30/20 rule is a widely-used starting point:

• 50% — Needs: Rent/mortgage, bills, food, transport, minimum debt payments
• 30% — Wants: Eating out, entertainment, hobbies, non-essential shopping
• 20% — Savings & debt repayment: Emergency fund, savings, paying off debts faster

In the real world, many UK households find the 50% needs target difficult — especially in high-rent areas. If your needs exceed 50%, focus first on building even a small emergency fund (£500–£1,000) before worrying about the ratios.

Step 5: Build Your Emergency Fund First

Before paying off debt aggressively or investing, aim to save one month's essential expenses as a buffer. This stops small emergencies (broken boiler, car repair) from sending you into debt.

Once that's in place, aim for 3 months of expenses in an easy-access savings account. This is your safety net for job loss or illness.

Step 6: Tackle Debt in the Right Order

Not all debts are equal. Prioritise in this order:

1. Priority debts first: Rent/mortgage arrears, council tax, gas and electric arrears, court fines. Missing these can cost you your home, utilities, or liberty.
2. High-interest debt next: Credit cards, store cards, payday loans. Pay minimums on all, then throw every spare pound at the highest-rate one.
3. Low-interest debt last: Student loans (Plan 1/2/4/5), 0% finance deals.

Step 7: Review Monthly

A budget only works if you check it regularly. Set aside 15 minutes at the end of each month to:

• Compare what you planned to spend vs what you actually spent
• Update for any changes in income or bills
• Celebrate wins — any money saved is progress
