Home battery storage cost in Bolton & Wigan
A home battery stores electricity to use later: solar power made in the day, or cheap grid power bought overnight on an off-peak tariff. You do not need solar panels to have one.

Installed prices at the current 0% VAT rate. MyJobQuote’s September 2026 UK average is £6,500. Fitting a battery at the same time as solar panels shares the labour and is usually cheaper than adding one later.
Usually included
- The battery and, depending on the system, a battery or hybrid inverter
- Wiring to the consumer unit and any existing solar
- Setting up the app and charging schedule
- Testing, an Electrical Installation Certificate and notifying Electricity North West
Often extra

- A long cable run to a garage or outbuilding
- Removing an old battery (£200 to £600)
What changes the price
- Capacity
- Bigger batteries cost more but cost less per kWh. Size it to the power you use in the evening, not your whole day.
- With or without solar
- A hybrid inverter with new solar can run both. Adding a battery to existing panels may need its own inverter.
- Where it goes
- Garages and utility rooms are common. The manufacturer’s rules on location, ventilation and temperature decide what is allowed.
- Your tariff
- An off-peak or time-of-use tariff is what lets a battery save money, so the installer should ask what you are on.
How long it takes
Around 1 to 3 days, according to MyJobQuote. A battery added to existing solar is usually at the shorter end.
Rules and certificates
Installing a battery in a home, including a standalone battery charged from the grid, has been zero-rated for VAT since 1 February 2024 and stays at 0% until 31 March 2027, as long as the installer supplies and fits it. A battery is a new connection to your electrical installation, so it should be fitted by a registered installer, tested and certified, and the network operator, Electricity North West, must be told.

Questions people ask
Can I have a battery without solar panels?
Yes. A battery on its own charges overnight on a cheap off-peak tariff and runs the house through the expensive evening hours. It qualifies for 0% VAT on its own.
What size battery do I need?
Look at how much electricity you use between late afternoon and bedtime. Many homes are comfortable with a medium 6 to 9 kWh battery. Bigger is only worth it if you have the solar or the cheap tariff to fill it.
Will a battery keep my power on in a power cut?
Not automatically. Many systems shut down in a power cut for safety. Backup needs a system designed for it, so ask for it at the quote stage.
Can I get paid for exporting from my battery?
The Smart Export Guarantee covers electricity you generate, such as solar. Some suppliers have tariffs that also pay for battery exports, so check with your supplier.
