Eskom’s tariff has already climbed 22.6% since 2024. Not projected — already on your bill. ⚡

12.74% in 2025. 8.76% more from this April. And a further 2027 increase is currently before the courts, with NERSA under a court order to decide by 31 August.

Waiting doesn’t freeze the number. It just means you pay the next one too.

We help you build a system that takes that variable off the table.
