About East Midlands

The East Midlands has a high proportion of detached and semi-detached homes, many from the post-war period, with above-average energy consumption. The region’s flat landscapes across Lincolnshire and Nottinghamshire also make it one of the stronger-performing areas for rooftop solar outside southern England.

According to MCS data, at least 5,637 certified home battery installations have been completed in the East Midlands region since September 2023 – part of a nationwide surge in domestic battery uptake.

Your savings with an 11.5kWh battery

The battery charges overnight at 9.5p and powers your home during the day, avoiding the 32.32p daytime rate. The saving is the difference between those rates, multiplied by how much energy the battery delivers each cycle.
