December Solar Offer: Bigger Savings, Bigger Battery Storage, Limited Time

If you’ve been thinking about solar for your home, December is one of the best times of the year to move forward. As we head into winter and get ready for 2026, The Little Green Energy Company is launching a limited-time December offer designed to give homeowners more value, more storage, and more long-term energy savings.

Whether you’re looking to reduce rising electricity bills, increase your home’s energy independence, or future-proof your property, this is the strongest set of incentives we’ve offered all year.

⭐ 1. Free Upgrade: 6kW → 10kW SIG Battery

Battery storage is the heart of any high-performing solar system — and this December, we’re upgrading anyone who installs a 6kW SIG battery to a 10kW system at no additional cost.

That means:

• £500 saved upfront

• ~£1,000 in additional lifetime energy savings

• More stored energy for evenings and winter usage

• Greater flexibility with time-of-use tariffs

For homeowners looking to maximise their investment, this upgrade delivers outstanding long-term value.

or you as a homeowner, that means:

⭐ 2. £350 High Street Gift Voucher

For systems where a SIG upgrade isn’t the best fit, you can opt for a £350 high street gift voucher when you sign in December. Ideal if you’re investing in:

• Solar-only systems
• Tesla Powerwall
• Premium inverter setups

A simple, flexible way to reduce your overall cost.

⭐ 3. Free First-Year Maintenance (worth ~£450)

Every solar system benefits from expert maintenance — and for homeowners who’d prefer additional peace of mind, we’re offering the first year of maintenance entirely free.

This includes:

• System health checks
• Optimisation for maximum yield
• Early-stage performance monitoring
• Priority support

A great option if you want ongoing protection without the upfront cost.

🗓️ Offer Deadline: 22 December

All three offers are available until 22 December 2025.

After that, our installation teams close for Christmas and the offer period ends.

If you want to lock in additional savings before the new year, now is the ideal time.
