Fuel Mix Disclosure
We are required by Ofgem to disclose our fuel mix for the year from April 2025 to March 2026
What is a fuel mix disclosure?
Annually, we publish our fuel mix to give you information on the energy sources we’ve used to supply our customers. We publish this information so that when you choose Ruby to supply your energy, you can be confident in your decision.
Will your fuel mix be changing?
As renewable energy becomes more and more common, our Fuel Mix will be following the same pattern! We want to make sure we’re doing everything we can to play our part in the fight against climate change and are committed to supporting the UK Government in it’s goal of Net Zero Emissions by 2050.
