Ruby Energy's fuel mix (April 2023 - March 2024) consisted of: 70% natural gas, 14% coal, 4% nuclear, 6% renewable, and 6% other sources. This is significantly more fossil fuel-dependent than the UK average, with only 6% renewable energy compared to the national average of 42.1%.

Ruby Energy rebranded from BES Utilities in August 2024. However, the company's history includes serious regulatory enforcement. The former BES operation faced Ofgem enforcement action in 2015 (£980k settlement including £311k consumer compensation) and criminal fraud convictions were secured in 2023 against previous leadership. The current management changed in May 2023, and a new external director was appointed in February 2025. Due diligence is recommended before switching.

Ruby Energy currently holds a 4.5/5 rating on Trustpilot. However, it's worth noting that the company underwent significant changes post-2023, including management restructuring. The ratings reflect current performance, but the company's BES history should be considered alongside current reviews.

Ruby Energy's CO2 emissions are 452g per kWh, which is 120% higher than the UK average of 205g per kWh. This is significantly above industry standards and means your business would have a substantially larger carbon footprint if you switched to Ruby. If sustainability is important to your business, you should explore suppliers with lower fossil fuel dependence and higher renewable content.

Yes. Ruby's fuel mix is heavily weighted toward fossil fuels (84% from coal and gas combined), with minimal renewable energy (6% vs 42% UK average). This means: high carbon emissions (120% above average), exposure to volatile gas markets, and limited hedging through renewables. If your business has ESG commitments or sustainability goals, Ruby Energy falls significantly short of industry benchmarks.

While fuel mix alone doesn't determine price, it does influence long-term stability. Ruby's heavy dependence on natural gas means the company is more exposed to gas market volatility. With limited renewable energy hedging, you may face less price stability compared to suppliers with diversified energy sources. This can translate to higher renewal rates when energy costs spike.

In 2015, Ofgem investigated BES Utilities and found breaches of customer contract terms and complaint handling obligations. BES admitted the breaches and agreed to a £980k settlement, including £311k in direct consumer compensation. Additionally, criminal fraud convictions were secured in 2023 against previous leadership for fraudulent trading (2014-2016). The company has since rebranded and changed management, but this history should inform your decision.

That depends on your priorities. Ruby's pros: established provider with 40,000+ customers, 4.5/5 Trustpilot rating, flexible contracts, 24/7 online management. Cons: significant regulatory and fraud history, very high carbon footprint (120% above average), minimal renewables (6%), heavy fossil fuel dependence, exposed to gas market volatility. If price is the only factor, you should compare quotes from other suppliers. If sustainability or stability matter, there are better alternatives.
