How It Works
The cost of living in the UK varies significantly by region. Key categories include housing (typically the largest expense at 30–40% of income), food and groceries, transport, energy bills, council tax and personal spending. London and the South East are substantially more expensive than the North and Midlands.
This calculator builds a monthly budget estimate based on your household size, location and lifestyle. It uses ONS data on average expenditure combined with regional adjustments to give you a realistic picture of what it costs to live in different parts of the UK.
Energy costs have been particularly volatile. The Ofgem price cap sets a maximum unit rate and standing charge for default tariffs, but actual bills depend on consumption. The calculator uses the current cap rates and typical usage figures to estimate your energy spend.
Example: Single person in Manchester
- Rent (1-bed flat): approx. £750/month
- Council tax (Band B): approx. £130/month
- Energy (gas + electric): approx. £110/month
- Food and groceries: approx. £250/month
- Transport (bus pass): approx. £70/month
- Estimated monthly total: approx. £1,310 (before discretionary spending)
