As you know from a prior article (Greening Scotland… One Home at a Time), I am recently moved up to the North-East Scotland, and after the shock of moving to a property with no Solar panels), I started looking into the short- to medium-term solutions I will put into place to improve our new home.
Arctic Improvements (a forward-thinking home improvements company who are commitment to greener, smarter living) was the only company I spoke to who told me that it was possible to install ONLY the storage batteries (and no solar panels) and thereby benefit from Octopus Energy‘s low rates over night: By storing the electricity until it is needed (which will be even more useful when we have the car-charger installed next year!).
So far, I feel more in control of my energy usage, and am even able to make alterations on the app to gain from Octopus’s free energy hours! And I am looking forward to monitoring my energy bills over next year!
As energy bills climb and climate concerns intensify, smart solutions that let you buy low, use high are more valuable than ever. One compelling setup combines Arctic Improvements’ storage batteries with Octopus Energy’s Go tariff—a powerful duo for budget-savvy, eco-conscious households.
Arctic offer a range of home energy improvement measures, and if you give Tina a call (0141 237 4563) or message (info@arcticimprovements.co.uk), and mention Zero Waste Llama, she will talk you through what they have done for me!
1. Storage Batteries from Arctic Improvements
Arctic Improvements offers home storage battery systems that seamlessly integrate with existing renewable setups or smart meters. These batteries allow you to store electricity for later use, reducing reliance on expensive grid power when demand—and prices—are highest. While you’ll need to confirm availability and specs directly on their site, they provide reliable, professional installations tailored to your home.
2. Low-Cost Overnight Charging with Octopus Go
Octopus Go is a fixed, low-rate electricity tariff offering ultra-cheap overnight power—typically 8.5 p/kWh between 00:30 and 05:30, available across the UK. This makes it ideal for charging a home battery during these hours when demand (and cost) is at its minimum.
Unlike more complex smart tariffs, Octopus Go doesn’t require an electric vehicle, a smart charger, or automation—making it accessible for anyone with a battery system.
Real-world users highlight the benefits:
“I charge the battery for 7 p, empty it for 15 p and then recharge it again for 7 p.”
—showing the potential of simple price arbitrage.
“No you don’t [need an EV]. It says that though. Smart meter sending readings is all.”
—confirming Octopus Go works perfectly with home storage batteries.
3. Maximizing Savings with Battery & Tariff Strategy
Here’s how the system works in practice:
- Purchase and install a storage battery via Arctic Improvements.
- Switch to Octopus Go and charge your battery overnight at ~8 p/kWh.
- Use stored energy during the day, avoiding peak rates of 25–30 p/kWh.
- Optionally, export surplus energy back to the grid if your setup supports it.
A simple example:
Charging 10 kWh at 8 p costs £0.80. Using that energy during peak hours at 28 p/kWh saves £2.00—a net daily saving of £1.20, or more than £400 annually.
4. The IPCC Perspective: Why This Matters for the Climate
According to the IPCC’s Sixth Assessment Report, the building sector accounts for 21 % of global greenhouse gas emissions, with the majority linked to electricity and heat demand. A key IPCC strategy is the SER framework—Sufficiency, Efficiency, Renewables—which shows that households can achieve comfortable living standards while using much less energy.
By using Arctic storage batteries in combination with Octopus Go, homeowners directly contribute to this framework:
- Sufficiency – By storing only what’s needed, batteries prevent waste and flatten demand surges that strain the grid.
- Efficiency – Cheap overnight charging reduces the need for inefficient, high-carbon peaking plants that are often fired up during daytime demand spikes.
- Renewables – Storage helps absorb renewable power (such as wind, which often peaks at night) and shifts it into daytime use—maximising clean energy consumption.
In other words, every homeowner who installs a battery isn’t just lowering their bills—they’re helping decarbonise the grid, cutting reliance on fossil fuels, and supporting the UK’s journey to net zero.
5. Why This Combo Works for Both Wallet and Planet
| Benefit | For Your Pocket | For the Environment |
| Cheap charging at ~8 p/kWh | Saves £400+ per year on bills | Encourages energy use when supply is cleanest and cheapest |
| Stored daytime use | Avoids peak prices of 25–30 p/kWh | Reduces demand for gas-powered peaker plants |
| Export surplus energy | Potential extra income | Supplies clean energy to the grid when it’s needed most |
| Grid balancing | Stabilises your costs long-term | Supports a renewable-ready, resilient grid |
| IPCC alignment | Household-level savings compound nationally | Helps meet climate targets by cutting building-sector emissions |
6. How to Get Started
- Explore Arctic Improvements’ battery options and choose a system that suits your household’s demand.
- Ensure you have a smart meter installed to qualify for Octopus Go.
- Sign up for Octopus Go and set your battery to charge during the 00:30–05:30 off-peak window.
- Optimise and monitor your usage—many batteries offer apps that make savings visible in real time.
In Summary
Pairing a storage battery from Arctic Improvements with Octopus Go’s off-peak electricity is a win-win: it saves you hundreds of pounds annually while making your household part of the global solution to climate change.
By charging cheaply overnight and using or exporting clean power during the day, you’re not just dodging high bills—you’re cutting emissions, supporting renewable energy integration, and aligning your lifestyle with IPCC climate strategies.
It’s proof that smart, sustainable living can be good for both your wallet and the world.
