Currently, the solar battery price in the UK ranges from around £2,500 to £12,500. The exact cost for your home will be determined by the solar battery capacity you need. To give you an indication of the cost of different solar batteries depending on their capacity, we have created an overview of their estimated prices below:
|Battery capacity (kWh)
|Solar battery price
|£2,500 – £4,000
|£3,500 – £5,000
|£5,000 – £7,500
|£7,500 – £10,000
|£10,000 – £12,500
As you can see, the solar battery storage price varies per capacity. Because every housing situation is different, it requires individual calculations to determine the precise cost. You will need to consult a specialist to find out what solar battery capacity is the most suitable for your energy consumption requirements.
Furthermore, you will also have to account for the installation costs involved in fitting a new solar battery storage for your home. These can be anywhere from £500 to £1,500, depending on which solar installer you choose to work, the complexity of the installation, and other factors such as the battery capacity. We’ll walk you through each factor in the next section and also give you a tip that can help you save time and money when looking for a solar installer.
The main factors that will influence the total cost of your new solar battery are the type of solar battery you choose, the capacity of the solar battery, its lifecycle, and the costs involved in the installation process.
At the same time, the cost of having a solar battery installed in your home can also change depending on whether you are purchasing it together with your solar panels. In this case, you might be spending less on your new solar battery installation.
To determine the exact costs for your situation, however, you will want to consult a specialist. You can also read our guide to learn more about the number of solar panels you may need, according to your household consumption habits: “How Many Solar Panels Do I Need?”
The chemistry of the battery is something you’ll need to consider, as it will impact the lifespan of your solar battery storage, which in turn affects your energy expenses. The solar battery types available to UK homeowners today are:
You can learn more about how these solar batteries work, how much they cost, and what you can expect to gain from them below.
Lead-acid is currently the cheapest solar battery storage option. One of these solar batteries costs around £2,000 for a battery with a 4kWh storage capacity. They have the longest history and are reliable.
They do, however, have a shorter lifespan in general, as well as a lower depth of discharge, meaning you’ll need to replace the batteries more often than other types. The good news, though, is that they are recyclable, so it can be a fairly environmentally-friendly process.
Lithium-ion solar batteries are the most mainstream solar batteries. They don’t need much maintenance to keep running and they have a longer life cycle of 4,000 cycles in comparison to the 1,800 of a lead acid solar battery.
In terms of costs, they are more expensive than the lead acid batteries, as they cost around £4,000 for the same 4kWh storage capacity. You should also bear in mind that they need to be installed by a professional to reduce any possible hazards, as they have a higher fire risk than other solar batteries.
These batteries are durable and can work at extreme temperatures, unlike some other variants. They are banned in some countries as the cadmium is toxic, so they might not be the best choice for everyone.
Nickel-cadmium solar batteries are also a more expensive option, as their estimated price is somewhere around £4,000 for a 4kWh capacity battery.
Boasting a long life and low discharge rate, nickel-metal hydride batteries are able to charge and discharge at temperatures below 0°C and above 60°C. This means that they are good options for homes subjected to harsh weather conditions.
In terms of price, the cost of these appliances ranges from £2,500 to £3,000 for a 4kWh battery capacity.
The solar battery capacity is how much energy is generated by your solar panels the unit can store for future use. Typically, the higher the capacity, the higher the price of the solar battery. You should also bear in mind the capacity of your solar panels, as well as the solar panel price in your calculations.
As you can see in the table above, solar batteries with a lower capacity like 3kWh cost somewhere between £2,500 – £4,000, while those with a higher capacity of 20kWh cost around £10,000 – £12,500.
For solar battery storage systems, a cycle is a complete discharge of the battery, followed by a complete charge. Some manufacturers provide an unlimited cycle guarantee. However, most of them offer an estimated figure that can range from 1,800 to 10,000 cycles.
You should give careful consideration to the lifecycle of solar batteries before purchasing one, as it will affect how long you can enjoy your appliance before having to replace it.
While solar batteries with more lifecycles can generally be more expensive, opting for those could help you avoid overspending on switching out batteries that have reached the end of their lifespan.
Alongside the costs of the solar battery itself, you also have to keep in mind that there are additional costs involved when it comes to installation. The exact cost for your home depends on factors such as the size of the solar battery system you need, the complexity of the installation, and the installer you choose to work with.
As an estimate, the installation costs for a solar battery are around £500-£1,500. To find out whether the costs for your home will be on the higher or lower end of this price range, you should contact a specialist who can give you the most accurate total costs for your new solar battery.
However, to find the best deal on installation costs, you should get information from more than one engineer. This allows you to compare figures and to choose the installer that best fits your budget.
While this is an important step in having a new solar battery fitted in your home, it can be extremely difficult to find installers to reach out to. You could spend hours looking up installation companies and reading reviews and you still might not find what you’re looking for.

Below you can learn more about the grants you can apply for and about the eligibility criteria you must meet.
By applying for this grant, you can earn money by transferring parts of the electricity stored by your solar panel battery to the electricity grid. You should check whether your energy supplier allows energy to be exported from your storage system.
If you live in England, Wales, or Scotland, you could benefit from the VAT reduction, which means that you will be paying 0% VAT on solar panels. When installing your solar battery at the same time as your new solar panels, the 0% VAT is applicable to your entire energy system.
This loan is only available to homeowners looking for solar panels in Scotland as it allows for savings on energy-efficient home improvements. For solar batteries, this means that you could get an interest-free loan of up to £5,000. You can also receive a loan of up to £6,000 for new, efficient solar panels.
Before applying for any of these grants, you should check that you meet their eligibility requirements. To be eligible for a solar battery grant in the UK today, these are the criteria you must meet:
