Buying energy via a broker or aggregator — safe?

Brokers and aggregators bundle customers for a collective rate — sometimes via an established supplier, sometimes as own Balance-Responsible Party. Four checks:

1. Who is the ultimate supply contractor? Read the agreementif nobody is named you're exposed on broker bankruptcy
2. Does the broker hold an ACM supply license or operate as intermediary? Intermediary = no own responsibility for supply
3. What are the exit terms? Brokers often tie to long-term price arrangements — exit costs reservation or stepped fees
4. Who is your point of contact on complaint? Many brokers vanish after sale and redirect you to the ultimate supplier. For energy collectives (e.g. Hollandse Wind, municipal initiatives): often GOOD deals but read terms.
