Frank Energie

Both amounts come from Frank Energie's comparison table (updated April 2026): fixed supply fee €7.25 per month and purchase fee €0.0182 per kWh. The table does not say whether the amounts include or exclude VAT (VAT basis not stated), nor whether the €7.25 applies per product. An older Frank page (dated 3 January 2025) states €7 per month, also without a VAT basis. For the purchase fee, Frank's own sources do point to a VAT-inclusive amount: Frank defines the all-in price as 'the market price plus purchase fee, energy tax and VAT', and in Frank's public price feed the all-in price is exactly market price + 21% VAT on the market price + €0.01815 purchase fee + €0.11085 energy tax (the VAT-inclusive rate). VAT is only added separately to the market price there, which means €0.01815 (rounded €0.0182) already includes VAT (€0.015 excluding VAT). This is derived, not stated verbatim. Frank bills hourly prices by default; you can switch to quarter-hour prices in the app.

Home battery: Slim Stroom Handelen: Frank steers a linked home battery to charge at low and discharge at high prices, including on the imbalance market; open to multiple brands. Smart traders get a 'Frank Slim discount' that sets purchase fees to zero (fair-use policy).

Feed-in: No feed-in costs. Per the comparison table (April 2026) and the knowledge base, exported power earns the market price plus a feed-in purchase fee of €0.0182 per kWh; the table explains that a positive value means you receive money. The invoice guide, however, says you pay a purchase fee on exported power; Frank's own pages are not consistent on this. With Slim Terugleveren (a linked inverter from brands including Enphase, SolarEdge, SMA, Huawei, Solis, Sungrow, GoodWe, Fronius and Growatt) Frank mentions a feed-in bonus of about 15% on the market price.
