Cyd Cymru

People across Britain are seeing bigger benefits by switching and collectively buying their energy together, saving between £60 and £250 per household per year.


Cyd CymruThe Vale of Glamorgan and Cardiff councils with support from other local authorities and housing associations across Wales, have launched “Cyd Cymru”.


Cyd Cymru provides an opportunity to change the way we buy our energy, simplify a complex tariff system and aim to address the issue of rising fuel prices as winter approaches.


Cyd Cymru is a Wales-wide collective switching buying scheme.  Wherever you live in Wales if you sign up and switch your energy supplier, you could be feeling the benefits.


The more people we can sign up, the better discounts we can negotiate.


How the Process Works

There is no obligation to switch supplier and you will have the final say on whether you want to switch or not



The process:


1. Registration: The first step is to register your interest, providing as much detail about your energy use as possible. You can do this online or on the telephone.


2. Energy Auction: An energy auction will then take place where Energy suppliers are asked to give their best price to those who have registered to be part of the collective.

3. New rate offered: You will be contacted with a personal offer calculated for you, based on the information you have provided.

4. You decide to switch: If you accept the offer, you will be assisted whether to switch to the new cheaper tariff.


5. Our partner, energy helpline, will assist you in completing the switch.
