- For comparisons based on your kWh consumption or the national average, we assume the following split across times of the day:
- 10% used during “peak” hours (5pm – 7pm)
- 37% used during “night” hours (11pm – 8am)
- 53% used during the remaining “day” hours (7pm – 11pm and 8am-5pm)

- For comparisons based on your kWh consumption or the national average, we assume that your average consumption is flat within each time band
- The “National Average” for calculations is 4,200 kWh per annum
- Where a tariff only has a single rate (24-hour), our platform sometimes refers to this as the “day” rate
- We assume you’re willing pay by direct debit and online billing if required to obtain the best price
- “Cashback”, “Welcome Bonuses”, and unit rate discounts are included in the calculations.
- It’s standard practice for electricity suppliers to jack up prices once your contract expires. To get a good value, you
**need to re-evaluate your options and most likely switch again as soon as your contract expires**. Mark your calendar! - All prices include VAT

## Battery Simulations

Batteries are assumed to be AC-coupled, and have a round-trip efficiency of 90%, unless otherwise specified. Capacity refers to the usable discharge amount on the AC side per cycle.

We assume max charge/discharge rates according to the following table, unless otherwise specified.

Battery Capacity | Assumed Max Charge/Discharge Rate |
---|---|

1 kWh | 1 kW |

2 kWh | 2 kW |

3 – 6 kWh | 3 kW |

7 – 10 kWh | 4 kW |

10-24 kWh | 6 kW* |

>24 kWh | 11 kW** |

** Approx three-phase limit
