A battery is the lever — solar is the option

Most homeowners assume the order is solar first, battery second. The actual economics in 2026 are usually the other way around. A 10kWh battery on Octopus Go pays back in 6-8 years just from tariff arbitrage — buying electricity overnight at 7-8p/kWh, discharging it during the day at the 25-30p/kWh peak rate you'd otherwise pay.

That works with or without solar panels. Add solar and the savings compound: surplus daytime generation goes into the battery instead of being exported at the SEG rate, lifting self-consumption from a typical 30-40% to 70-80%.

Battery economics

Self-consumption — solar only vs solar + battery

A solar-only home in the North East uses about a third of what it generates — the rest gets exported at SEG rates (typically 15p/kWh). Add a battery and self-consumption rises to 70-80%, saving you peak-rate imports (27p+/kWh).

35%

self-consumption

Solar only — most generation exported during the day when no-one is home.

78%

self-consumption

Solar + 10 kWh battery — daytime surplus charges the battery, used in the evening.

92%

self-consumption

Solar + battery + EV charger — Eco+ mode parks the EV on free solar surplus.

Home battery cost

How much does a home battery cost in 2026?

A typical 10kWh home battery installation costs between £4,500 and £6,500 in 2026 if installed standalone, or £3,500–£5,000 added to a new solar PV install (some setup costs share). Premium options (Tesla Powerwall) sit at £8,500-£10,500 for a 13.5kWh unit.

Installation costs are turnkey, including the battery unit and inverter (or hybrid inverter for new solar installs), all electrical work, EPS sub-board where applicable, DNO notification, and AMP's 5-year workmanship guarantee on top of the manufacturer warranty.

What's actually in the bill

  • Battery unit and battery management system. The biggest single line. LFP chemistry dominates new installs in 2026 — safer, longer-cycle than older NMC cells.
  • Inverter (or hybrid). Bundled into the price for new solar+battery installs. AC-coupled retrofits use a separate battery inverter.
  • EPS sub-board. Where you want grid-outage backup, a dedicated consumer-unit feeds critical circuits during a power cut. Tesla Powerwall does whole-home backup without this sub-board.
  • NICEIC-certified electrical install. All cabling, isolators, RCD protection, surge protection.
  • Mounting and casework. Wall-bracket or floor-mounted depending on space and unit type.
  • DNO notification. G98 for batteries up to 3.68kW per phase; G99 for larger units (Tesla Powerwall and stacked battery packs typically need G99).
  • Tariff switch support. We help you move to a time-of-use tariff and configure the battery charging schedule.
  • App setup, commissioning, walk-through. Live monitoring configured on your phone before we leave.

Battery brands we install

Which battery is right for your home?

Smart tariffs

The tariffs that make a battery pay

A home battery only saves money if you're on a time-of-use tariff that has a meaningful gap between off-peak and peak rates. The current UK options:

Tariff Off-peak rate Off-peak window Notes
Octopus Go 8.5p/kWh 5 hours overnight (00:30-05:30) Simple flat off-peak window. Standard choice.
Intelligent Octopus Go 7p/kWh Smart-scheduled around your EV target Best if you have an EV; smart charger required.
Octopus Agile variable (sometimes <0p) Half-hourly variable rates Lowest rates if you can shift load. Engaged users only.
EDF GoElectric ~9p/kWh 5 hours overnight Available to all EDF customers.
British Gas Electric Driver ~9.5p/kWh Overnight band Bundle option with British Gas import.
OVO Charge Anytime 7p/kWh Smart-scheduled EV-required but uses battery + EV interchangeably.

We help you compare and switch tariff as part of the install. For most households without an EV, Octopus Go or EDF GoElectric is the right choice. For households with an EV, Intelligent Octopus Go usually wins. For engaged customers willing to actively manage charging, Octopus Agile can deliver materially lower rates in windy or sunny periods.

Emergency Power Supply

EPS — what happens to your home during a power cut

Northern Powergrid network reliability across the North East is among the better in the UK, but unplanned outages do happen — typically 1-3 per year for an average household, usually lasting under an hour. An Emergency Power Supply (EPS) configuration means your home automatically transfers to battery power within seconds of grid failure, with no action needed from you.

Whole-home backup (Tesla Powerwall)

Tesla Powerwall does full-home backup as standard — every circuit stays live during the outage. The 13.5kWh capacity supports a typical 3-4 bed home for 8-16 hours of essentials operation, or 4-6 hours with full normal usage including electric showers, induction hob, and any heat pump operation.

Critical-circuits backup (SolarEdge, Solis)

A dedicated sub-consumer-unit feeds your chosen "critical circuits" during a grid outage. Typically: lighting, internet/comms, fridge/freezer, boiler controls, gas heating, and one or two ring-mains. A 10kWh battery feeding critical circuits supports a typical home for 16-30 hours.

Cost of adding EPS

Tesla Powerwall includes whole-home EPS in the base price. SolarEdge and Solis critical-circuits EPS add approximately £400-700 to the install (sub-board, additional cabling, transfer switch). Whether the additional cost is worth it depends on how much you'd value uninterrupted essentials during an outage.

Works best together

What pairs best with a home battery

A battery on a smart tariff pays back without any other kit. Add solar or an EV charger and the economics compound — surplus daytime solar fills the battery instead of being exported, and EV charging happens on tariff arbitrage even when the sun isn't shining.

☀️

Solar panels

Battery captures daytime solar surplus and releases it in the evening peak. Lifts solar self-consumption from 30-40% to 70-80% and tightens combined payback to 6-9 years.

⚡

EV charger

Smart tariffs like Intelligent Octopus Go schedule EV charging during your battery's charging window. Battery covers daytime loads, EV draws from the same cheap overnight supply.

Home battery FAQs

Do I need solar panels to have a battery?
No. Battery storage works with or without solar panels. Without solar, you can charge from the grid at cheap overnight rates and use the stored energy during expensive peak hours.

How much can I save with a home battery?
Savings depend on your energy usage and tariff. With a time-of-use tariff, you can save £400-800 per year by shifting your energy use to off-peak hours. Combined with solar, savings can be even higher.

How long do home batteries last?
Most home batteries come with a 10-year warranty and are designed to last 15+ years. They can typically handle 6,000-10,000 charge cycles before any significant degradation.

Will a battery keep my lights on during a power cut?
Yes, if your battery system includes an Emergency Power Supply (EPS) function. Most modern batteries like Tesla and SolarEdge Powerwall offer automatic backup power during outages.
