Your energy bill has more bargaining power together.

No. Comparison sites help one household shop across published offers. Bloc groups households — each of which has supplied a bill — into a defined buying group, and has retailers compete for the group with offers that aren't on public comparison sites.

Never. You set a minimum annual saving before joining, and nothing is switch-ready until an offer clears it. Even then, you review the offer and decide.

Your bill is what makes the group credible. It proves real usage and real current pricing, which lets retailers bid seriously and lets Bloc calculate your specific saving rather than a generic estimate.

Your current retailer and plan, billing period, total amount, electricity usage, and tariff details like usage rate, supply charge and any feed-in tariff. You review and can correct everything before joining.

By similarity: state and region, usage band, and whether you have solar. Grouping like-with-like means a single retailer offer can be priced fairly across the whole group.

The model is a fee from the retailer when a switch completes — similar to existing acquisition channels, but for a group at once. Households don't pay to join.

You'll see the best offer anyway, with an explanation of why it fell short, and you can stay in for the next round. You're never switched to something below your threshold.

No. When an offer clears your threshold you review the full details and explicitly confirm before any switch request is made.

You can enter the key details manually — it takes a couple of minutes. A profile entered that way is labelled as entered by you rather than read from a bill, so it is clear where the figures came from.

Yes. Every offer is applied to the annualised usage from your own bill to estimate your annual cost and saving. Annualising one bill ignores seasonality, so figures are labelled as estimates.
