Watch & Read: This UK Energy "Loophole" Saves You 70%
Smart export + time-of-use tariff combination explained in 1 minute.
What this video covers
This is one of KMM's mid-funnel explainer videos — useful once you're past the basic 'should I get solar' question and into the how-does-it-work detail.
Smart export + time-of-use tariff combination explained in 1 minute.
The savings maths in plain English
- The single biggest lever in solar economics is your import tariff. At 28p/kWh, every self-consumed solar kWh saves 28p; at 18p/kWh the same kWh saves 18p
- The second biggest lever is self-consumption ratio. Without battery, typical domestic ~38%; with battery, 75–85%
- Smart Export Guarantee pays you for unused solar at 4–16.5p/kWh
- Cheap-window battery charging on tariffs like Octopus Cosy adds an extra revenue layer — buy at 7p, displace 28p grid use
- UK electricity inflation has averaged 9.2%/year from 2010–2025 — every year you delay, the next system pays back faster
