Battery storage — Hampshire
EnSmart Battery Installation in Hampshire
EnSmart batteries for Hampshire homes, sized from your actual usage, with the grid paperwork, the seasons and the power-cut reality explained before you commit.
Our Hampshire towns run from Farnborough and Aldershot across to Basingstoke, Alton and Petersfield, and every one of their town centres sits in SSEN’s Southern Electric Power Distribution area. That makes the grid side of an EnSmart SolarAll installation consistent across the patch. We install the SolarAll-H hybrid inverter and ELV battery packs, the same kit as in our own job photos, and quote them from a survey with the specification itemised.
The county overview lives on solar panels in Hampshire, and the general sizing and warranty guide on battery storage. For the town detail, see battery storage in Basingstoke, Petersfield or Fleet.
Quick answer
EnSmart in Hampshire:
- Our own work: EnSmart is the battery system in HCE's own job photos; the survey confirms whether it suits your home before anything is quoted.
- Cost: the Energy Saving Trust puts home battery storage at £1,500 to £10,000, with a 5 kWh system at around £4,600; a quote for your home comes from a survey of your usage.
- VAT: residential battery installations carry 0% VAT until 31 March 2027, then 5% from 1 April 2027.
- Grid: every battery is notified to, or approved by, the local network operator depending on its size (G98 or G99); the installer handles it.
- Power cuts: a standard grid-tied battery shuts down when the grid does; backup has to be designed in and is never assumed.
- 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.

How a home battery gets fitted in Hampshire
Four steps from first call to switch-on. No pressure at any stage, and a straight answer if it would not pay its way.
- Step 1
Your usage, not a guess
We look at when your Hampshire home uses power, especially evenings, and your tariff, because that, not the sunniest month, decides the battery size.
- Step 2
Sizing and siting
Where the unit can go (garage, utility room or an outside wall, as the manufacturer allows), whether it pairs with existing panels, and a written, itemised quote.
- Step 3
Installation and notification
Fitting and commissioning, with the battery notified to or approved by your network operator depending on its size. Backup in a power cut only if it is designed in.
- Step 4
Settings and handover
Charge and discharge set up around your tariff, the app explained, and the warranty documents in your hand.
How EnSmart fits Hampshire homes
Hampshire’s market towns have a balanced housing mix rather than a single type. Alton’s 8,525 households are 29.7% semi-detached, 23.9% detached and 21.4% terraced, with 21.3% in purpose-built flats; Petersfield’s 6,859 are 29.7% detached, 23.6% semi and 23.0% terraced (Census 2021). For the semis and detached homes the EnSmart ELV-W wall pack, rated IP50 for indoor use only, usually goes in the garage or utility room. Terraces with no spare room are where the IP55 ELV-F floor packs earn their place, since EnSmart rates them for outdoors away from direct sunlight, and the IP65 SolarAll-H inverter can be wall-mounted inside or out.
With SSEN as the operator for all six town centres, the paperwork is one route: under G98 we notify equipment up to 16 A per phase (3.68 kW) after commissioning, within 28 days; above that, a G99 application must be approved before work starts. EnSmart’s single-phase SolarAll-H runs 3–6 kW on the datasheet, so the inverter size we choose decides the route, and we tell you which one applies when we quote. Farnborough’s town centre is about 3.4 km from UK Power Networks’ South Eastern area, so we confirm addresses on that side by postcode.
Hampshire: sunshine, the grid and local uptake
PVGIS puts a 4 kWp south-facing array at about 136 kWh in December (Basingstoke) to 139 kWh (Fleet and Petersfield), and at about 482 kWh (Fleet and Aldershot) to 506 kWh (Petersfield) in June. Petersfield’s 4,128 kWh a year is the best annual figure among these six towns. Even there, December averages about 4.5 kWh a day on our arithmetic, under one 5.12 kWh ELV-W pack. DESNZ records about 18,659 solar PV installations across Rushmoor, Hart, Basingstoke and Deane and East Hampshire (end of 2025, our sum), and DVLA about 17,497 privately kept plug-in vehicles across the four councils, up from about 12,452 a year earlier (our sum).
Ofgem’s 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, down from 51.3 and 57.6 the year before. The SolarAll-H’s UPS function only comes into play on an installation designed and wired for backup; a standard system shuts down with the grid.

EnSmart in Hampshire: questions
Which network operator handles an EnSmart installation in Hampshire?
For the six Hampshire towns we cover, SSEN: every town centre from Farnborough to Petersfield sits in its Southern Electric Power Distribution area, though Farnborough is close enough to UK Power Networks’ area that we check the postcode. We submit the G98 notification or the G99 application; you do not deal with the network yourself.
My Hampshire home has no mains gas. Does an EnSmart battery make more sense?
It depends on how you use electricity, not on the gas connection alone. DESNZ estimates about 17% of homes in East Hampshire and in Basingstoke and Deane have no mains gas, but that tells us nothing about your heating or your evening load. We size the ELV packs from your actual consumption and tariff at the survey, and if a battery would not pay its way, we say so.
Is it worth adding an EnSmart battery when I already have an EV in Basingstoke or Fleet?
Sometimes. DVLA counts 6,203 privately kept plug-in vehicles across Basingstoke and Deane and 4,111 across Hart (June 2026), and most EV drivers charge the car directly on an off-peak tariff. The battery’s job is the house’s evening load. We look at both together, including whether your main fuse takes a charger and a battery without an upgrade.
