Collapse of supplier Bulb could add more than £150 to energy bills

Cost of bailing out UK company threatens to top 4bn by next spring because of soaring gas prices

Households could end up paying more than 150 extra on their energy bills because of the collapse of Bulb, as the price of bailing out the failed supplier threatens to top 4bn by next spring.

The cost of bailing out the UK company, which has about 1.4 million customers, has escalated because of rising wholesale gas prices since Russia's invasion of Ukraine.
