Ofgem steps in as energy supplier collapses

7th November 2025

Energy regulator Ofgem is assigning a new supplier for 8,400 customers after energy provider Tomato Energy collapsed.

Ofgem intervened to protect supply for all affected, confirming that energy provision and funds, including credit balances, are secured under its ‘supplier of last resort’ safety net.

Tomato Energy was banned from taking on new customers in April after building up debts of £3 million it was also hit with a proposed £1.5 million fine last month for failing to meet financial resilience rules.

The company filed a notice of intent to appoint administrators in October.

Rohan Churm, Director for Financial Resilience and Control at Tomato Energy said: “I want to reassure Tomato Energy customers that they do not need to worry. They will not see any disruption to their energy supply, and any credit domestic customers have on their accounts remains protected under Ofgem’s rules.

“We are working quickly to appoint a new supplier for all existing customers, and they should not switch in the meantime.”
