A 9.5kWh GivEnergy battery costs £3,000–£4,000 retrofitted to existing solar, or from £8,000 as part of a combined solar and battery installation. On time-of-use tariffs, it also saves money by charging cheaply overnight and discharging at peak rates. ### Key Takeaways - Home battery storage in Stockport raises solar self-consumption from **~40% to 70–80%**, substantially improving the economics of solar panels. - GivEnergy 9.5kWh battery: **£3,000–£4,000** added to existing solar. Combined solar + battery from **£8,000**. - On time-of-use tariffs (Octopus Agile, Intelligent Octopus), battery saves an additional **£200–£500/year** by charging cheaply overnight, independently of solar generation. - GivEnergy batteries carry a **10-year warranty** and 6,000+ cycle life — lasting the lifetime of your solar system. - Optional **Emergency Power Supply (EPS)** function provides backup power to selected circuits during grid outages. - No planning permission required in Stockport — battery units install internally with no external visual impact. - All installations covered by our [4.9★ Trustpilot](/reviews) guarantee — we serve all SK postcodes. ## How Much Does Battery Storage Cost in Stockport? Configuration Battery Size Cost Best For Retrofit battery (existing solar) 9.5 kWh GivEnergy £3,000–£4,000 1–3 bed home with existing solar Retrofit battery (existing solar) 13.5 kWh GivEnergy £4,500–£5,500 3–5 bed home / EV charger users Solar + battery (new install) 4kW solar + 9.5kWh From £8,000 New to solar, highest self-use Solar + battery + EV charger 4kW + 9.5kWh + charger From £9,500 EV owners, maximum savings 70–80% solar self-use with battery vs ~40% without £300+ extra saving/yr with battery vs solar alone 10 yrs GivEnergy warranty 6,000+ cycle life £200+ ToU tariff extra saving/yr Octopus Agile users ## How Does Battery Storage Work With Time-of-Use Tariffs in Stockport? Time-of-use electricity tariffs — such as [Octopus Agile](https://octopus.energy/agile/) and Intelligent Octopus — offer electricity at 7–9p/kWh overnight (off-peak) and charge 30–40p/kWh during peak evening hours. A GivEnergy battery can be programmed to charge from the grid overnight at cheap rates and discharge during expensive peak hours — saving £200–£500/year independently of your solar generation. When combined with solar panels, the battery covers the full strategy: solar charges the battery during the day; the battery discharges in the evening; on very cloudy days or in winter, cheap overnight grid electricity tops up the battery instead. The GivEnergy app manages this automatically. See [our time-of-use tariff guide](/battery-storage/time-of-use-tariffs) and [battery savings calculator](/battery-storage/savings). ### Book a Free Stockport Battery Storage Survey Compatible with all major solar inverters · GivEnergy authorised installer · All SK postcodes [Book Free Survey](/free-quote) [Battery Size Guide](/battery-storage/what-size-battery) ## Frequently Asked Questions — Battery Storage in Stockport How much does battery storage installation cost in Stockport? £3,000–£4,000 for a 9.5kWh GivEnergy battery retrofitted to existing solar. From £8,000 for a combined solar + battery installation. From £9,500 for solar + battery + EV charger. What size battery do I need for my Stockport home? A 9.5kWh battery suits most 2–3 bed Stockport homes with a 4kW solar system. Larger homes or EV users may benefit from 13.5kWh or stacked battery systems. See our [battery size guide](/battery-storage/what-size-battery). Can I add battery storage to my existing solar panels in Stockport? Yes — GivEnergy batteries retrofit to most existing solar systems. Your current inverter compatibility is assessed at the free survey. Some older systems require a hybrid inverter replacement (£500–£1,500 additional). How does battery storage work with time-of-use tariffs? The GivEnergy battery charges overnight on cheap-rate electricity (7–9p/kWh) and discharges during peak hours (30–40p/kWh), saving £200–£500/year on top of solar savings — managed automatically via the GivEnergy app. What is the payback period for battery storage in Stockport? Battery-only payback: 8–12 years. Combined solar + battery payback: 8–11 years — shorter than solar alone because self-consumption rises to 70–80%. Does battery storage require planning permission? No — home battery storage is permitted development. Units install internally (garage, utility room, loft) with no external visual impact. What brands do you install in Stockport? We install [GivEnergy](/battery-storage/givenergy-review) as our primary battery product — 10-year warranty, 6,000+ cycles, UK-based support, compatible with all major solar inverters. Can battery storage power my home during a power cut? GivEnergy batteries include an optional EPS (Emergency Power Supply) function providing backup power to selected circuits during grid outages. Confirm EPS configuration during your Stockport survey.
