The cost of living in Cardiff varies widely depending on your rent, household size and lifestyle, with housing usually being the biggest expense. Alongside rent or mortgage payments, budget for council tax, energy, water, food, transport and other essentials. Compare current rents and bills for the area you are considering, and check Cardiff Council’s cost-of-living support pages for local help. You can also use the benefits calculators on GOV.UK to see whether you might qualify for financial support based on your circumstances.
