Battery storage systems have revolutionised how UK households manage electricity. When paired with the right smart tariff, these systems allow homeowners to store low-cost electricity during off-peak hours and use it during peak times, reducing energy bills and even generating income through energy exports. In this article, we explore the best tariffs for battery storage in the UK and explain how to maximise the benefits of these innovative solutions.
The Evolution of Smart Tariffs for Battery Storage
Traditionally, electricity tariffs in the UK were fixed, with consumers charged the same rate for all units consumed, regardless of the time. This changed with the introduction of Economy 7 in the 1970s, which offered cheaper electricity rates during a seven-hour window at night. This concept paved the way for modern smart tariffs, designed for homes with battery storage and renewable energy systems like solar panels.
Smart tariffs enable homeowners to:
- Charge batteries during off-peak hours at reduced rates.
- Use stored energy during peak hours, bypassing higher costs.
- Export surplus energy back to the grid, earning additional income.
Top Smart Tariffs for Battery Storage
Here are the leading UK smart tariffs for homes with battery systems:
| Supplier | Tariff Name | Day Rate (p/kWh) | Off-Peak Rate (p/kWh) | Peak Rate (p/kWh) | Export Rate (p/kWh) | Notes |
|---|---|---|---|---|---|---|
| Octopus Energy | Go | 27p–31p | 8p–10p | n/a | 8p | Requires an EV |
| Octopus Energy | Flux | 25p–28p | 12p–15p | 35p–38p | 15p–26p | High export rates but expensive peak rates |
| British Gas | Electric Driver V6 | 29p–31p | 7p–9p | n/a | 4p–6p | Requires an EV |
Prices correct as of May 2024.
How to Maximise Savings with Smart Tariffs
1. Choose the Right Battery Storage System
High-capacity systems from manufacturers such as Growatt, Givenergy, Sigenergy or Lux provide sufficient storage for off-peak charging and daytime usage. These systems are designed for seamless integration with smart tariffs.
2. Optimise Energy Storage and Usage
Smart technology in modern batteries allows homeowners to schedule charging during off-peak hours and discharge stored energy during peak hours. This ensures minimal reliance on grid electricity at higher rates.
3. Take Advantage of Export Tariffs
Smart tariffs like Octopus Flux offer generous export rates of up to 26p/kWh. With a robust storage system, you can sell surplus energy during peak demand periods, generating significant income.
4. Monitor and Adjust
Smart meters provide real-time insights into energy usage and generation. Use this data to refine your energy habits, ensuring you charge and discharge your battery at optimal times.
The Benefits of Smart Tariffs for Battery Storage
- Lower Energy Bills: Off-peak charging can save hundreds of pounds annually compared to standard tariffs.
- Income from Exports: Selling surplus energy to the grid can generate additional income.
- Sustainability: Using and exporting renewable energy contributes to a greener energy grid.
- Energy Independence: Reduce reliance on fluctuating grid prices by storing and managing your own energy.
