A sample answer to question 1

What does a typical day as an energy sales advisor involve, and what makes someone good at it?

A typical day starts with checking my call list or inbound queue and the daily targets, followed by a short team briefing on tariff changes or compliance updates. Most of the day is spent speaking to customers, either calling warm leads or taking enquiries, checking their usage and current deal, and quoting suitable fixed or variable options. Every sale needs accurate details recorded, such as meter numbers, contract end dates and a clear summary of the terms, so there is a fair amount of CRM updating and follow-up. I think the best advisors are good listeners first. Energy is a confusing subject, so people respond to someone who explains unit rates and standing charges plainly and does not rush them. You also need resilience, because plenty of calls end in a no, and attention to detail, because one wrong digit in an MPAN can cause a failed switch. Above all, honesty matters, because Ofgem expects customers to be treated fairly.

Common mistake to avoid: Describing it as only hitting targets; ignoring compliance and record keeping
