Energy Cost Trends: 2021-2026
How Scotland's average household energy bill compares against solar + battery savings over the past six years. From 2024 onwards, well-configured solar-battery systems generate more value than households spend on energy.
| Year | Avg. Annual Bill | Solar+Battery Saving | Net Energy Cost |
|---|---|---|---|
| 2021 | £1,138 | £820 | £318 |
| 2022 | £1,971 | £1,540 | £431 |
| 2023 | £1,834 | £1,680 | £154 |
| 2024 | £1,692 | £1,780 | -£88 |
| 2025 | £1,741 | £2,090 | -£349 |
| 2026 (proj) | £1,847 | £2,340 | -£493 |

Policy Timeline
Key government policy milestones affecting Scottish homeowners and the renewable energy market.
Market Outlook: 2026-2030
Growth Drivers
- Energy prices expected to remain above pre-2021 levels through 2030
- Battery storage costs falling 8-12% annually, improving payback
- Heat pump grant (BUS) driving rapid adoption away from gas
- New build regulations requiring renewable energy from 2028
- Smart tariff proliferation making battery arbitrage more accessible
Key Risks
- Export tariff rates may decrease as solar penetration increases
- Grid capacity constraints in some rural areas slowing connections
- Potential reduction in government grant funding post-2027
- Installer capacity constraints during peak demand periods
- Planning permission requirements for listed buildings and conservation areas
