What a home battery costs before any help
DESNZ's statistics for MCS-certified retrofit batteries in 2025/26 show the average job at about 5 kWh, 10 kWh or 15 kWh, with prices per kWh falling as size rises. Multiplying the average size by the mean price per kWh gives roughly the figures below. Supplier package prices are usually lower because the statistics include premium kit, backup and awkward roofs.
