Battery storage — Surrey
Battery Storage Haslemere
Home batteries for Haslemere 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 Haslemere has a sharper seasonal job than in most Surrey towns. PVGIS estimates that a 4 kWp south-facing array in the town makes about 497 kWh in June but only about 133 kWh in December. Almost half of the Neighbourhood Plan area is wooded, so winter shade from trees can cut that further on many plots. A battery here is about moving summer and shoulder-season generation into the evening, and storing off-peak electricity in winter, not about running the house on sunshine all year. Start with what solar panels in Haslemere would generate on your own roof.
The town's homes help. In the two Haslemere wards, 37.3% of households live in detached houses (2021 Census), and next door in Hindhead the figure is 46.1%. Larger houses usually have a garage, utility room or plant space where a battery can sit near the consumer unit. The harder cases are the listed buildings in the town-centre conservation area around High Street, Petworth Road and Lower Street. Our main battery storage guide explains the products and how sizing works.
Quick answer
Battery storage in Haslemere:
- 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 Haslemere makes about 497 kWh in June but about 133 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 Haslemere 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.

How a home battery gets fitted in Haslemere
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 Haslemere 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 Southern Electric Power Distribution 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.
Where a battery fits in Haslemere's homes
The 2021 Census counted 5,319 households across the Haslemere Critchmere and Shottermill ward and the Haslemere East and Grayswood ward: 37.3% detached, 23.7% semi-detached, 14.5% terraced, 18.4% in purpose-built flats and 3.2% in converted or shared houses. Ownership is high, at 35.3% owned outright and 34.5% with a mortgage, against 15.8% private renting and 13.8% social renting (ONS Census 2021, TS044 and TS054). In the detached houses of Grayswood and Beacon Hill, a garage or utility room is the natural place for a battery. On the semis and terraces of Shottermill and Critchmere, an outside side wall or the back of a garage usually works; a mid-terrace with no side access may mean siting the unit indoors near the meter. Lofts suit some units and not others, depending on the manufacturer's temperature and access limits.
About one household in five in these wards lives in a flat or converted house, where a battery needs the freeholder's or landlord's agreement and a suitable place outside the flat itself. In the Haslemere Town Centre Conservation Area, buildings mostly date from the 16th to the 20th century and many are listed. On a listed building, any fixing or cable run through historic fabric is a matter for the council's conservation team before anyone drills. On an unlisted house in the conservation area, a battery inside a garage or outbuilding avoids most visual questions; a wall-mounted unit is best kept off the street-facing elevation.
What a Haslemere 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 Haslemere itself, for a 4 kWp array at 35° facing due south with 14% system losses:
- 4,070 kWh a year in total
- 497 kWh in June and 501 kWh in July
- 133 kWh in December and 156 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 Haslemere
Haslemere is in the corner of Surrey served by SSEN Distribution rather than UK Power Networks: the town centre sits in SSEN's Southern Electric Power Distribution licence area. Your installer, not you, deals with SSEN. Under the G98 rules, a type-tested system rated up to and including 16 A per phase (3.68 kW single-phase) is notified within 28 days of commissioning. Anything bigger needs a G99 application approved before installation, and a 4 kW inverter (17.39 A) already counts as bigger. SSEN says it aims to respond to small-generation applications within 10 working days, which is why we build the application into the timetable rather than finding out later.
In a power cut, a standard grid-tied battery switches off with the grid. That is a safety requirement, not a fault, and it applies in Grayswood just as in the town centre. If you want lights, the fridge and the boiler controls to keep running, the system has to be designed for backup from the start, with the extra isolation hardware that needs. If you work from home in Grayswood or Hindhead and want the router and lights to stay on, that is worth discussing at survey; we will set out the cost and tell you honestly whether it is worth it.
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 Haslemere
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.

Haslemere battery questions
Haslemere is so wooded: is a battery still worth having?
It can be, but be honest about winter. PVGIS gives a 4 kWp south-facing array in Haslemere about 133 kWh in December against 497 kWh in June, before any tree shade, and the Neighbourhood Plan puts woodland at about 48% of the area. In winter a battery earns more by storing off-peak electricity than by storing solar. If your tariff has little peak-to-off-peak difference and your roof is shaded, we may advise against one.
Do I need to tell SSEN about a battery in Haslemere?
Your installer does, not you. Haslemere town centre is in SSEN Distribution's Southern Electric Power Distribution area. A system up to 16 A per phase (3.68 kW single-phase) is notified within 28 days of commissioning under G98. Anything larger needs a G99 application approved before work starts. SSEN says it aims to respond to small-generation applications within 10 working days.
Can I put a battery on a listed building in Haslemere town centre?
Possibly, but not without the council's conservation team. Many buildings in the Haslemere Town Centre Conservation Area are listed, and work affecting a listed building's fabric needs listed building consent. A battery in an outbuilding or a modern rear extension avoids most of the problem; a unit fixed to historic walls is a conversation to have with the council first.
Will a battery keep my Haslemere home running in a power cut?
Not unless it is designed to. A standard grid-tied battery shuts down with the grid. Backup needs extra hardware that isolates the house safely, plus a decision about which circuits to keep, usually lighting, the fridge, the router and the boiler controls. We set out what that adds before you choose.
