If you are already on the Intelligent Go tariff, your rates are not changing... yet! Octopus has a great track record of protecting existing customers for a period. However, for new sign-ups or those moving onto the tariff now, the figures have shifted slightly:
While a 3p drop in export payments might seem a bit of a letdown, it actually highlights a golden rule in the world of renewables: Energy is always worth more in your own home than it is sold back to the grid.
With the gap between the day rate (30.5p) and the export rate (12p) widening, the goal is simple: Stop exporting and start storing.
The Tesla Powerwall 3 is the perfect partner for these changes. By storing your solar energy instead of selling it for 12p, you avoid buying it back later at 30.5p. That's an immediate "profit" of 18.5p for every single unit of electricity you use yourself.
Load shifting is simply moving your energy use from the expensive day rate to the cheap overnight rate. Even if the sun doesn't shine, your Powerwall 3 can "buy" cheap energy at night to give you a massive discount all day.
Let’s look at the numbers for a single Tesla Powerwall 3 (13.5kWh capacity):
That is over £1,100 saved every year just by shifting where your electricity comes from—before you even account for your free solar power!
We’re not just saying that—the "stars have aligned" for Grimsby homeowners right now with three huge financial incentives:
Tesla is celebrating 1 million installations with a limited-time rebate. You can claim £375 back per Powerwall 3 installed (up to £750 for two units). This is paid directly to you via a Virtual Visa card after your installation is registered.
2. 36 Months Interest-Free Finance
At Wil-Lec, we want to make green energy accessible. We are currently offering 0% interest-free finance for 3 full years.
The Wil-Lec Math: If your Powerwall 3 saves you ~£94 a month (our calculation above), and you use our 0% finance, your energy savings could effectively pay for a huge chunk of the battery every single month.
The government has extended the 0% VAT on retrofitted battery installations. This saves you 20% compared to previous years—a saving of roughly £1,500 to £2,000 on a typical install.
We’ve been Grimsby’s trusted electrical experts since 1997. As the first and only certified Tesla Powerwall 3 Partner installer in North East Lincolnshire, we don't just "fit" batteries—we design smart systems that actually save you money.
Don't let tariff changes dictate your bills. With a Tesla Powerwall 3, you can lock in low rates and achieve true energy independence.
