Top 10 Areas hardest hit by cost of living crisis in Wales revealed

The areas hardest hit by cost of living crisis in Wales are concentrated in urban communities across South Wales and parts of the north.

1 APRIL 2026

The areas hardest hit by cost of living crisis in Wales are concentrated in urban communities across South Wales and parts of the north, according to new analysis of the latest Welsh deprivation data.

Using the latest Welsh Index of Multiple Deprivation, the findings highlight neighbourhoods where households are already under significant financial strain—whilst energy tariffs are falling in April they are expected to increase in July 2026.

While cities such as Cardiff and Swansea feature prominently, areas in Wrexham and Denbighshire also rank among the most affected, showing that the crisis spans both major urban centres and smaller towns.

Top 10 areas hardest hit by cost of living crisis in Wales

1. Denbighshire 004E, Denbighshire (North Wales)

Ranked the most income-deprived area in Wales, this neighbourhood faces a combination of low household income and relative isolation from major services, intensifying the impact of rising living costs.

2. Caerphilly 022E, Caerphilly (South Wales)

With one of the worst overall deprivation scores in Wales, this area experiences deep-rooted economic challenges across multiple domains, leaving residents highly exposed to rising energy and food prices.

3. Cardiff 039E, Cardiff (South Wales)

One of three Cardiff areas in the top 10, this neighbourhood highlights how severe deprivation exists within Wales’ capital, where high living costs amplify the financial strain on low-income households.

4. Cardiff 013D, Cardiff (South Wales)

Despite relatively good access to services, many residents here struggle to afford essentials, illustrating how availability does not always translate into affordability during the cost-of-living crisis.

5. Wrexham 010C, Wrexham (North Wales)

High levels of employment deprivation mean joblessness is a key driver of financial hardship, leaving households particularly vulnerable to rising energy bills.

6. Cardiff 039B, Cardiff (South Wales)

Another Cardiff neighbourhood facing significant income deprivation, reinforcing the concentration of hardship within specific parts of the capital.

7. Swansea 011A, Swansea (South Wales)

This coastal community combines income deprivation with health challenges, demonstrating how financial pressure can compound wider social and wellbeing issues.

8. Swansea 019A, Swansea (South Wales)

Economic hardship in this area intersects with higher levels of crime-related deprivation, highlighting the broader social impacts of financial stress.

9. Wrexham 017E, Wrexham (North Wales)

Education deprivation is a key factor here, suggesting long-term structural challenges that could be worsened by rising household costs.

10. Swansea 011C, Swansea (South Wales)

Poor housing and living environment conditions add to income pressures, leaving households particularly exposed to increases in energy and housing costs.

What the data shows

The rankings are based on the income deprivation component of the Welsh Index of Multiple Deprivation, which measures the proportion of people experiencing low income at neighbourhood level (LSOAs).

These small areas, typically covering around 1,500 residents, allow for highly detailed analysis of where financial hardship is most concentrated.

Why these areas are hardest hit

Neighbourhoods with high income deprivation are particularly exposed to the cost-of-living crisis because residents spend a larger share of their income on essentials such as:

  • energy
  • food
  • rent and housing

This means even modest price increases can have a disproportionate impact, pushing more households into financial difficulty.

Energy price rises could deepen the pressure

The situation is expected to worsen with planned energy price increases in July 2026, which are likely to place additional strain on already vulnerable households.

For many families in the areas hardest hit by cost of living crisis in Wales, energy is a non-negotiable cost. Rising bills could:

  • increase levels of fuel poverty
  • reduce spending on other essentials
  • widen existing regional inequalities

Key patterns and insights

Urban deprivation is highly concentrated

All of the top 10 areas are urban, showing that financial hardship in Wales is concentrated within specific neighbourhoods rather than spread evenly across regions.

Cardiff’s hidden inequality

With three areas in the top 10, Cardiff illustrates how deprivation can exist alongside economic growth, with stark differences between neighbourhoods.

South Wales dominates the list

Cardiff, Swansea and Caerphilly account for the majority of the hardest-hit areas, highlighting the concentration of deprivation in the south.

Multiple pressures overlap

These communities often face challenges across income, employment, health and housing simultaneously, increasing their vulnerability to economic shocks.

Linking deprivation data to real-world insights

Working with neighbourhood-level data such as LSOAs can present challenges when integrating with other datasets.

Doorda links all LSOAs to postcodes, making it easier to combine deprivation data with other sources, including property and geodemographic insights. This enables a more complete understanding of how the cost-of-living crisis is affecting different communities.

The bigger picture

While the rankings are relative, they provide a clear snapshot of where financial pressure is most severe in Wales.

As energy prices rise again in July, the areas hardest hit by cost of living crisis in Wales are likely to face even greater challenges—highlighting the need for targeted support and policy intervention.

Frequently asked questions about the cost of living crisis in Wales

What is the cost of living crisis in Wales?

The cost of living crisis in Wales refers to the ongoing rise in essential expenses such as energy, food and housing, which is placing increasing financial pressure on households. The impact is particularly severe in low-income communities where wages have not kept pace with rising costs.

Which areas are hardest hit by the cost of living crisis in Wales?

The areas hardest hit by cost of living crisis in Wales are typically those with the highest levels of income deprivation. These include neighbourhoods in Cardiff, Swansea, Caerphilly, Wrexham and Denbighshire, where households are more exposed to rising energy bills and everyday costs.

What is an LSOA in Wales and why does it matter?

A Lower-layer Super Output Area (LSOA) is a small geographic area used for statistical analysis, usually covering around 1,500 people.
In the context of the cost of living crisis in Wales, LSOAs help identify exactly which neighbourhoods are most affected, allowing for more targeted analysis and policy responses.

How is income deprivation measured in Wales?

Income deprivation in Wales is measured using the Welsh Index of Multiple Deprivation (WIMD), which ranks areas based on the proportion of residents experiencing low income.
Areas with the lowest ranks are the most deprived, meaning they are more vulnerable to the effects of the cost of living crisis in Wales, particularly when essential costs such as energy increase.

Why are some areas more affected by the cost of living crisis in Wales?

In more deprived areas, households tend to spend a higher proportion of their income on essentials like energy, food and rent. This makes them more sensitive to price increases.
With energy prices expected to rise, the cost of living crisis in Wales is likely to hit these communities hardest, increasing the risk of fuel poverty and financial hardship.
