Our teams are working hard to repair the burst water main affecting supplies to customers in the Llanrumney/St Mellons areas of Cardiff. We are expecting work to continue through the night.

Bottled water stations are available at:

  • Eastern Leisure Centre, Llanrumney Avenue, CF3 4DN
  • Tesco Supermarket, St Mellons, CF3 0EF

We will also be directly supporting our vulnerable customers on the Priority Service Register. We are doing all we can to restore supplies as soon as possible and apologise for the inconvenience this has caused.

June 2022


In North Wales our focus throughout June was in Flintshire. Most of the events were in the community exhibition van for our “Cost Of Living Roadshow” in places such as Flint Retail Park, ASDA Queensferry, Broughton Retail Park and Aldi in Buckley.

The weather was glorious with plenty of nice warm sunshine, which called for one or two ice creams to cool us down!

We had the opportunity to speak to lots of people who were seeking advice on their water and energy bills. Thank you to Warm Wales, Nest, Groundworks North Wales, DWP Welfare Team, Citizen Advice and Woodys Lodge who all supported Tracey Jones on the van.

If you are interested in coming along to any of the roadshows or would like us to bring the van to one of your events, please get in touch. We also attended events at Soughton Hall, organised by Newcis and Mostyn Village Hall as part of the Cost Of Living Road Shows.

It has been a busy month across June for the South Vulnerable Customer Community Team.

We have taken ourselves deep into our communities to reach those who cannot reach us. There has been supermarkets, baby showers, schools, libraries food pantries, community centres, hospitals and more!

There's nowhere we won't go to reach our most vulnerable of customers!
