Ofgem has issued a £1.6 million fine to Shell’s B2B energy arm for “serious overcharging of business customers”. The regulator found that Shell-owned Hudson Energy Supply UK (HES) - now Shell Energy UK - breached 10 licence conditions by outsourcing elements of its day-to-day customer operations without appropriate supervision. Issues found included “serious unjustified overcharging” of customers, as well as failure to return credit refunds owed.
