Energy brokerages like to hide the fact they are energy brokers by calling themselves something completely different. Energy consultants, buying groups, they are all the same. A buying group will normally tell you that there is ‘power in numbers’ and suggest that you can get cheaper prices by buying as a group (normally schools, farms etc), this isn’t always the case in in most situations you’re actually not receiving any savings at all. They will also tell you that they offer ‘bill analysis’ as part of the service, something you get for free with a normal energy supplier anyway!
