Inverness has grown fast, with new estates around Culloden, Westhill and Inshes, but beyond the city most Highland homes are off the gas grid and many heat with electricity. Storms off the Atlantic can cut power for hours or days. A battery here is as much about resilience as savings.
Which tariff region is Inverness in?
Inverness and the Highlands are in the North Scotland electricity region. Intelligent Octopus Go charges 7.6p at night and 37.65p by day, excluding VAT, published 8 October 2026. Homes still on older electric heating tariffs should compare carefully, because some heating tariffs work differently and a battery may change what suits you best.
How does a battery help Highland homes with electric heating?
Many off-gas Highland homes use storage heaters, panel heaters or a heat pump, so electricity bills are high. A battery charged on the cheapest overnight rate can run the house, and sometimes the heat pump, through the expensive day and evening. The more electricity you use, the more a correctly sized battery can shift.
What is a typical battery system in Inverness and the Highlands?
In Inverness itself, 5–10kWh is typical for newer estates. In rural Highland homes, 10–15kWh with backup is common, often paired with solar on a large roof. A 15kWh-plus battery typically costs £6,000–£11,000 installed at 0% VAT, checked October 2026, with backup equipment usually extra.
Do batteries cope with cold Highland winters?
Yes, if they are sited sensibly. Most lithium batteries charge slowly below about 0°C, so an unheated outbuilding in a Highland glen may need a battery with built-in heating or an indoor location. Our comparison table flags which batteries suit cold sites, and the installer checks this at survey.
Frequently asked questions
Do you cover remote Highland and island homes?
Yes. We install through MCS-certified partners across the Highlands. Remote and island addresses can cost more because of travel.
Can a battery run my home off-grid?
Some systems, such as Sunsynk, are used off-grid, but that needs careful sizing and usually a generator. Most homes stay grid-connected with backup.
Will a battery work with my storage heaters?
It can, but storage heaters already charge overnight. A survey checks whether your daytime use justifies a battery.
