Wales contains some of the cheapest places to live in the UK. The mid- and west-Wales authorities (Powys, Carmarthenshire, Ceredigion) consistently rank among the cheapest UK areas on rent, and the post-industrial South Wales valleys have similar profiles. Cardiff, the Welsh capital, is the most expensive Welsh authority but is still cheaper than most English cities of comparable size. Average earnings in Wales are lower than in England, which closes some of the affordability gap, but the rent-driven cost picture remains favourable.
We've ranked 22 Welsh local authorities by what it costs a single person to live there each month. Every figure traces back to official data: ONS for rent, MHCLG / Scottish Government / Welsh Government for council tax, Ofgem for energy, Water UK for water. The cheapest area is Powys at around £1,099/month, against a UK average of £1,461/month.

Regional context
Average earnings in Wales are lower than the UK average (around £30,000/year compared to £35,000 nationally), which moderates the affordability picture for people working locally. Cardiff has the highest costs in Wales but is still cheaper than most English cities of similar size. Welsh local authorities also use council tax bands A-I (rather than A-H), which gives a more granular range of rates than England.
How we calculated this
Each area's monthly cost is the sum of: median 1-bed rent (ONS Price Index of Private Rents), council tax at Band D with the 25% single occupier discount applied, the Ofgem monthly energy estimate, the average monthly water bill for the area, £220 groceries, and £80 transport.
