About West Midlands
The West Midlands is one of the most densely populated regions outside London, with a high proportion of 1950s–1970s semi-detached homes and pronounced evening peak electricity demand. Solar PV installation rates have been rising sharply since 2022 as electricity prices increased.
According to MCS data, at least 6,056 certified home battery installations have been completed in the West Midlands region since September 2023 – part of a nationwide surge in domestic battery uptake.
Your savings with a 5 kWh battery
The battery charges overnight at 9.5p and powers your home during the day, avoiding the 33.8931p daytime rate. The saving is the difference between what the stored energy would have cost at the day rate and what it cost to charge overnight, allowing for charging losses.
overnight rate
daytime rate (West Midlands)
per day
(5 kWh battery)
5 kWh × 33.8931p − (5 ÷ 0.9) kWh × 9.5p = 169.4655p − 52.7778p = 116.6877p saved per day
116.6877p × 365 days = £425.91/year, best case
Best-case payback: £2,499 ÷ £425.91 = about 5.9 years
Rates from the Octopus Energy API (product GO-FIX-12M-26-09-29, Octopus Go 12M Fixed, region E, direct debit, checked 10 October 2026). The 90% round-trip efficiency is our assumption, because EcoFlow does not publish one for the STREAM. This is a best case: one full cycle every day, with all of it used at the day rate. Real savings will be lower. Best-case payback on £2,499 fully installed is about 5.9 years. See how we worked it out.
