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.

This month has been very busy for us in the community. “Vera” has had lots of adventures in North Wales across Flintshire and Denbighshire and we hosted a cost of living event at the Dewi Sant Centre in Pensarn.

In South Wales we collaborated with lots of our lovely internal and external partners. From Foodbanks to Warm Hubs, to Supermarkets & Rubgy Clubs we were everywhere.

We even attended a Welsh Water Drop in Event at the Senedd to talk to the MS’s about all our help and support we have for our customers; during the Cost Of Living Crisis.
