With energy prices at an all-time high, a cost-of-living crisis and rows over windfall taxes, it is unsurprising that energy companies fail to make our top 100 index. For the average UK family energy costs have roughly doubled over the past two years. For water companies, considerable concern over pollution in rivers and seawater have similarly created consumer concern and negative publicity.

The treatment of vulnerable customers on pre-payment meters by some energy companies also came under the media spotlight as third-party contractors, working on behalf of major suppliers, were found, in some instances, to have shown little care and concern for customers in difficult circumstances.

"Energy price hikes and the cost-of-living crisis have dominated consumer concerns over the past year. In addition, in the water sector, there has also been a backlash against the discharge of raw sewerage into waterways. As a result, no energy or water companies have made the top 100 list this year."
