Utilities supplier boss, Andy Pilley, has spoken out against the ever-increasing use of bogus tenancy documents within the industry. Mr Pilley, the owner of national commercial gas and electricity supplier, BES (Business Energy Solutions), has seen an 'alarming increase' in forged change of tenancies submitted by brokers. Brokers approach suppliers with new clients and in exchange are paid an introductory fee. Once the details have been processed, clients often enter an out of contract rate with their previous supplier, which can mean paying double the amount they were before. Now, on behalf of the businesses that are at risk, BES is calling for a stop to it.
