Battery Installer Glasgow 2026
Battery installation in Glasgow — retrofit to existing solar or specify with new install.
Quick answer
A typical 10kWh home battery install in Glasgow costs £4,500-£12,500 depending on brand and capacity. The strongest economics come from pairing battery storage with the Octopus Flux tariff, which can add £200-£400/year of arbitrage profit on top of solar self-consumption savings.
Battery brands we install in Glasgow
- Tesla Powerwall 3 (13.5kWh, integrated 11.5kW inverter, EPS backup) — £10,500-£12,500
- EcoFlow PowerOcean (5-30kWh modular, IP65 outdoor-rated) — £4,000-£18,000

- Sigenergy SigenStor (5-48kWh modular, optional built-in EV charger) — £8,000-£35,000
Retrofit or new install
Both work. AC-coupled batteries retrofit cleanly onto existing solar systems — typically a 1-day install on site. We handle DNO notification and electrical compatibility for any setup.
Octopus Flux — the maths in Glasgow
Octopus paused Flux to new customers in March 2026 and, as of 16 September 2026, its Flux page is taking sign-ups again. Octopus's published South Scotland rates for that day: off-peak import 14.98p/kWh (02:00-05:00) · peak import 34.94p/kWh and peak export 27.19p/kWh (16:00-19:00) · standard import 24.96p/kWh.
A 10kWh battery charged off-peak and exported in the peak clears about £1.22 per full cycle before round-trip losses. How many spare cycles you get in Glasgow depends on how often your panels leave the battery short — in Scotland that is mostly November to February.
