Price of new energy storage box in the UK

It also touches on the cost of solar battery storage in the UK, which, according to Solar Guide, ranges from £1,200 to £6,000. Expensive? Perhaps it's a stretch, but shaving off a few pounds from your energy bill, might just be worth it!

As renewable capacity is added to the grid, the need to store and flexibly manage electricity grows with it. This is where the crucial role of battery energy storage systems (BESS) come into play, storing and releasing energy for when it's needed most. We look at what's happening with the growth of BESS in the UK.

This report will be launched to coincide with Clean Power Grid Conference 2025, 1 May 2025 at the IET, London. Overall though, the breakdown of the battery storage pipeline in the UK indicates a position of growth, with a large proportion of the pipeline capacity in early development, in planning and consented stages.

Effective use of battery storage will also provide energy system cost savings and benefits for businesses and consumers by enabling energy that is produced at times of high generation be stored and used during peak demand times.

However, a more precise way to assess their value is by using the £/kWh metric, which stands for price per kilowatt-hour of storage. This pricing can vary between £265 and £415 per kWh. The more affordable options often come from Chinese importers, while the higher end of the spectrum features premium brands like Tesla from the United States.

The UK's total battery storage project pipeline currently contains a total of 127GW of capacity. Figure 1 demonstrates the amount of capacity at each development stage as a proportion of the total pipeline. 8% of the capacity pipeline in the UK is operational or under construction, with 31% approved and yet to begin construction.
