Absolute cowboy of a company, I have no idea how they have a 4* rating. I can only assume this is through fraudulent ratings. I wouldn't recommend BES to my worst enemy. Customer service has been appalling, their management of my data and other customers data is embarrassing (I was called a different company in correspondence numerous times). They also blocked my account from moving over when I terminated my contract and billed my usage from 4 kw/ph to 6.5 kw/ph whilst they made it impossible for me to move to my new supplier. After pointing out this obvious attempt of ramping up my bill and blocking my transition as a means of profiting further, they declined to reason why they blocked my account and demanded payment at the ridiculously increased rate. DO NOT USE THIS COMPANY EVER!!!
