Tesla UK launched its Renewable Energy Bundle on 8 May 2026, a packaged offer that combines an eight-panel rooftop solar installation with a Powerwall 3 home battery for £199 per month over four years at 0% interest. The price is exclusive to Tesla owners, requires a £1,747 deposit and is installed by BOXT, Tesla's UK partner (Not a Tesla App, British Brief).
What Is in the Bundle
The package is a fixed kit — eight panels, one Powerwall 3, full installation — sold as a monthly subscription rather than as discrete products. The total cost is fixed up front, the financing is 0% over 48 months, and the deposit covers an early share of the equipment.
| Item | Detail |
|---|---|
| Solar | 8-panel rooftop installation |
| Battery | Powerwall 3 |
| Term | 48 months at 0% APR |
| Deposit | £1,747 |
| Monthly payment | £199 |
| Eligibility | Tesla car owners (UK) |
| Installer | BOXT |
Non-Tesla customers can still request a quote through BOXT, but only Tesla owners get the £199 headline rate.
Adding the Car: £494 per Month
Tesla also lets UK buyers stack the bundle on top of a Model 3 lease. With the Model 3 starting at £295 per month, the combined home-energy-plus-car payment lands at £494 per month — Tesla's first attempt at presenting energy and mobility as a single line on a household budget rather than as separate purchases.
Tesla claims the solar-plus-storage setup can save a typical UK home about £1,450 per year on energy bills, by self-consuming and time-shifting cheap or self-generated electricity. The figure is Tesla's own estimate and depends on tariff, roof orientation and consumption pattern; UK households should compare it against their last 12 months of usage rather than treat it as guaranteed.
Why This Matters for the UK Market
This is the first time Tesla has sold a fully-integrated, single-payment energy package in the UK. Powerwall 3 has been on sale through installers since 2024 and the Tesla solar offering arrived through a small partner network later than in the United States. Bundling the two products with a single direct-debit price simplifies a category that, until now, required a homeowner to commission an installer, finance the kit separately and run a self-consumption optimisation by hand.
The move also reinforces Tesla's strategic line that the car, the home battery and the solar system should be marketed as one product ecosystem (AOL UK). For Tesla owners with the right roof and a four-year horizon, the maths is straightforward: if expected savings are close to the claimed £1,450 per year, the net cost lands close to break-even over the term, with the Powerwall 3 and panels as long-life residual assets.
Caveats Before Signing
Three things matter when comparing the bundle against the alternatives. First, eight panels is a small system — about 3.4 kWp at common panel ratings — and may not cover the full annual consumption of a four- or five-bedroom home. Second, the £199 price is fixed for four years, but the underlying tariff savings depend on the wholesale gas and electricity market, not on Tesla. Third, the £1,747 deposit is non-refundable once installation begins, so cancellation flexibility is narrower than with a typical Powerwall purchase.
For UK households who own a Tesla, have a south-facing roof and have already used a Powerwall calculator, the bundle is competitive on a like-for-like basis. For everyone else, the right next step is a quote against a custom solar design rather than against the marketed monthly price.
