Energy bills in south Wales have more than doubled since 2008 — and new research suggests four in ten people are still too embarrassed or afraid to seek help when they can’t afford to pay.
Now, with the Iran conflict pushing wholesale gas prices sharply higher and a significant price cap rise expected in July, the situation could be about to get worse before it gets better.
British Gas Energy Trust, working with Age Cymru Dyfed, is bringing free drop-in advice events to four west Wales venues this month to help households get on top of their bills before that happens.
Sessions take place at Prince Philip Hospital in Llanelli on 19 May, Glangwili Hospital in Carmarthen on 20 May, Asda Llanelli on 27 May and Tesco Ammanford on 28 May — all running from 10am to 1pm and open to customers of any energy supplier.
The average domestic electricity bill in south Wales has climbed from £444 in 2008 to £1,129 — a rise of more than 150% in under two decades. South Wales households are among the hardest hit in the UK, with rural grid maintenance costs, higher heating demand and limited access to competitive tariffs all contributing.
Carmarthenshire families reliant on heating oil have faced some of the sharpest increases of all, with many paying triple what they once did — and rural communities have faced the additional threat of fuel theft as prices have rocketed.
The £150 average reduction applied automatically to bills from April offered some relief. But analysts at Cornwall Insight warn that the Ofgem price cap is on course to rise by around 20% in July — pushing the average annual bill from £1,641 to £1,973 — more than wiping out any April saving.
The driving force is the conflict in Iran. US and Israeli strikes against Iran began on 28 February 2026, prompting Iran to warn ships not to cross the Strait of Hormuz — a waterway that usually provides passage for around 20% of the world’s petroleum and liquefied natural gas supply. UK wholesale natural gas prices rose by roughly 75% between late February and late March as a result.
The government has responded with an energy package aimed at reducing the effect of higher gas prices on electricity bills, including offering voluntary long-term fixed contracts to low-carbon generators and raising the electricity generator levy from 45% to 55%. But the NIESR has warned the government has little fiscal space to provide anything like the £40 billion support package deployed during the 2022 energy crisis.
Swansea West MP Torsten Bell has written about the need to protect households from the economic fallout of the Iran conflict, while Citizens Advice Cymru has warned there is already no sign of easing in the cost of living crisis across Wales.
New research commissioned by British Gas Energy Trust found 40% of people still don’t seek help when struggling with bills. Stigma and embarrassment are the biggest barrier, cited by 38% of respondents — up from 33% the previous year. Others wrongly believe they won’t qualify for support (29%), or find the application process too daunting (17%).
It is in this context that the west Wales drop-in events take on added significance — offering a rare chance to get free, practical, face-to-face help at a time when many households are bracing for another difficult winter.
At the Llanelli, Carmarthen, Ammanford and Asda sessions, trained advisers will help with budget planning, managing energy debt, applying for debt write-off grants and accessing energy-saving measures. British Gas representatives will also be on hand to explain payment plan options and support schemes.
Tracey Talbot, Interim Chief Executive Officer at British Gas Energy Trust, said the partnership with local charities was designed to bring help directly into communities. “No one should feel alone in this — and we want people to know that help is not only available, but designed to work for them, wherever they are in life,” she said.
Daniel Barr, Senior Vulnerable Customer Lead at British Gas, said the first conversation with an adviser could make a real difference. British Gas has committed £140 million to help customers with energy bills since 2021 — the biggest voluntary support package from an energy company, it says.
Research also found 67% of people believe there should be more government and charity programmes to help manage rising energy costs. With the July price cap rise looming, the four events in west Wales this month may come at exactly the right moment for households already struggling to keep up.
