Battery storage — Hampshire
Battery Storage Farnborough
Home batteries for Farnborough homes, with or without solar panels — sized from your actual usage, with the costs, the seasons and the power-cut reality explained before you commit to anything.
Battery storage in Farnborough has to fit a borough built more of semis, terraces and flats than big detached houses: across Rushmoor, only 16.5% of households live in a detached home (Census 2021). That shapes where a battery can go far more than the weather does. If you are still weighing up panels, start with solar panels in Farnborough, which covers roofs and the town’s conservation areas.
This page covers the storage side for homes in Cove, Southwood, West Heath, North Camp and the older streets of South Farnborough: where a unit physically goes, how SSEN’s network handles the paperwork, and what Rushmoor’s figures on solar and plug-in cars show. Our main battery storage guide explains products and sizing. Here we keep to Farnborough, and we will tell you if a battery is not worth it for you.
Quick answer
Battery storage in Farnborough:
- Cost: the Energy Saving Trust puts home battery storage at £1,500 to £10,000, with a 5 kWh system at around £4,600; your own figure comes from a survey of your usage.
- Seasons: PVGIS estimates a 4 kWp south-facing array in Farnborough makes about 484 kWh in June but about 134 kWh in December — size the battery for your evenings, not for summer.
- VAT: residential battery installations carry 0% VAT until 31 March 2027, then 5% from 1 April 2027.
- Grid: central Farnborough is on SSEN Distribution's Southern Electric Power Distribution network; the installer notifies or applies to the operator depending on the system's size.
- Power cuts: a standard grid-tied battery shuts down when the grid does; backup needs to be designed in from the start, and we will tell you whether it is worth it.
- Who fits it: HCE is a NAPIT member (73495), MCS-certified for solar PV and battery storage via NAPIT, and a HIES Consumer Code member.

Where a battery fits in Farnborough's homes
Semis are Rushmoor’s largest group at 32.1% of households, with detached houses at 16.5% (ONS Census 2021, TS044). In the 20th-century streets of Cove, West Heath and Southwood, a semi with a side garage or a utility room is the straightforward case: the battery goes there, near the consumer unit and away from bedrooms. A loft is not a fallback for lack of space; placement follows the manufacturer’s manual and the BSI’s PAS 63100 fire-safety standard, and an engineer has to be able to reach the unit.
Terraces (23.5%) and purpose-built flats (23.2%) together make up nearly half of Rushmoor’s homes. A mid-terrace with no side access and no garage often leaves only a rear external wall, if the cable route works. Flats need the freeholder’s consent, and with 21.5% of households renting privately and 16.2% in social housing (Census 2021, TS054), the landlord or housing association is the first conversation for many. Five conservation areas sit in Farnborough, Farnborough Hill, Farnborough Street, Manor Park, St Michael’s Abbey and South Farnborough, so keep any outdoor unit off the street side there and check with Rushmoor first; on a listed building, ask the council about listed building consent before anything is fixed.
What a Farnborough roof generates through the year
A battery earns its keep by moving daytime generation into the evening, so the shape of the year matters more than the annual total. We ran the European Commission's PVGIS 5.3 (European Commission Joint Research Centre) for Farnborough itself, for a 4 kWp array at 35° facing due south with 14% system losses:
- 3,960 kWh a year in total
- 484 kWh in June and 487 kWh in July
- 134 kWh in December and 148 kWh in January
In summer a modest array fills a battery most days; in midwinter it rarely will, and the battery's job shifts to storing cheaper off-peak electricity if your tariff offers it. That is why we size storage from your evening usage and tariff, not from the sunniest month. East- or west-facing roofs and shading change these figures more than the town does — which is what the survey measures.
Method: PVGIS 5.3 (European Commission Joint Research Centre), 4 kWp, 35° tilt, due south, 14% system losses, building-mounted, PVGIS-SARAH3, 2005–2023, monthly output, run 15 October 2026.
The grid and power cuts in Farnborough
Farnborough is on SSEN Distribution’s network, in the Southern Electric Power Distribution licence area, rather than UK Power Networks’. SSEN is told about every battery: under G98, equipment up to 16 A per phase (3.68 kW) is notified by the installer before commissioning or within 28 days after it, and anything larger needs a G99 application approved before work starts. SSEN says it aims to respond to fast-track small-generation applications within 10 working days. A 4 kW inverter, at 17.39 A, is already over the G98 line, so a larger hybrid system in GU14 may well go the G99 route.
On power cuts, be clear about what you are buying. A standard grid-tied battery shuts down when the supply drops, so a battery in a Cove garage will not run the fridge through an outage unless the system was designed with backup: a backup-capable inverter or gateway and a separate backup circuit. That adds cost and is only worth it if you would use it. If panels are already on a North Camp or West Heath roof, the battery is notified too, and the installer checks whether the property’s combined output stays under the G98 line.
Ofgem's reported 2024/25 figures for Southern Electric Power Distribution show about 41.8 supply interruptions per 100 customers and about 51.2 minutes lost per customer over the year, against 39.7 and 35.1 across Great Britain.

What a home battery costs in Farnborough
The honest national anchor is the Energy Saving Trust's: home battery storage ranges from £1,500 to £10,000, a 5 kWh system costs around £4,600, and a typical home system might be 10 kWh. Energy Saving Trust also says there is no exact formula — sizing comes from your own consumption, that a battery's typical lifespan is about 10 to 12 years, and that fitting storage at the same time as panels costs less than a separate visit later.
Residential battery installations carry 0% VAT until 31 March 2027, reverting to 5% from 1 April 2027. Export payments under the Smart Export Guarantee are set by each supplier and must be above zero — they change on short notice, which is why we never print one. Our own price comes from a survey of your usage, tariff and wiring, and arrives itemised — the battery, the inverter or hybrid unit, the network notification, commissioning and warranties as separate lines.
When we would tell you not to: if your evening usage is low, if your tariff gives you little difference between peak and off-peak, or if a smaller solar array would already cover what you use in daylight, a battery can take a long time to pay its way — and we will say so rather than sell you one.

Farnborough battery questions
Can I fit a battery in a Farnborough flat?
Sometimes. 23.2% of Rushmoor households live in purpose-built flats (Census 2021, TS044), and the freeholder or managing agent must agree before anything is fixed to the building or wired into the supply. If you rent, as 21.5% of households privately and 16.2% socially do (TS054), the landlord or housing association decides. Even then, the unit needs a location that meets the manufacturer’s manual and the PAS 63100 fire-safety standard, which a small flat may not offer.
Will a battery keep my Farnborough home running in a power cut?
Not by default. A standard grid-tied battery shuts down when SSEN’s supply drops, so it keeps nothing running unless backup was designed into the system with a backup-capable inverter or gateway and a dedicated circuit. That adds cost. Ofgem’s reliability figures for the Southern Electric Power Distribution area are printed on this page; use them, and what you would actually want kept on, to decide whether backup is worth paying for.
Is a battery worth it with an EV in Rushmoor?
It can be, if your evening use is high. DVLA counts 2,201 privately kept plug-in vehicles across Rushmoor at the end of June 2026, up from 1,491 a year earlier; the borough’s much larger all-keeper total is mostly company registrations, so we do not use it. Most owners charge the car directly off-peak, leaving the battery for the house. A 7.4 kW charger draws 32 A continuously against a typical 60 A, 80 A or 100 A main fuse, so the supply is checked when both are fitted.
Do I need to tell SSEN about a battery in Farnborough?
Your installer does. Farnborough is in SSEN’s Southern Electric Power Distribution area, so SSEN, not UK Power Networks, is notified. Up to 16 A per phase (3.68 kW) that is a G98 notification, before commissioning or within 28 days after; above it, a G99 application must be approved before work starts, and SSEN says it aims to answer fast-track applications within 10 working days. Ask any installer which route your system needs.
