Is the Boxt Tesla Powerwall deal good value?

It depends on the price you are quoted and whether you need a battery of that size, or solar as well. Compare the total cost of your quote with what the battery would save you on your tariff. Households that just want 5 kWh of overnight shifting can pay from £2,499 for an installed EcoFlow STREAM.

Who installs Tesla Powerwall in the UK?

Boxt describes itself as a Tesla Energy Premium Installer and installs the Powerwall 3. Other installers also fit Powerwalls, so it is worth comparing quotes.

Boxt Tesla Powerwall 3: How Buying Through Boxt Works

The short answer

BOXT describes itself as a Tesla Energy Premium Installer and installs the Powerwall 3, on its own or with solar. Prices, finance terms and eligibility change, so get a current quote and read the terms before you commit. If all you want is the cheap-overnight-tariff savings, a smaller battery-only install may be enough: Habo Energy installs a 5 kWh EcoFlow STREAM from £2,499, which saves up to about £420 to £490 a year on Octopus Go in the best case (see how we worked it out).

What to check in a Boxt Tesla quote

Total cost. Add the deposit to all the monthly payments, not just the headline monthly figure.
Interest and term. Check the interest rate, the length of the agreement and whether there is any final payment.
Eligibility. Check whether any promotional price is limited to particular customers.
Who provides the credit. The finance agreement names the lender; read it before you sign.
Grid connection. Ask whether your install needs a G98 notification or a G99 application, and whether the quote covers any fees.

Bundle or battery-only? Run the solar maths first

Direct answer

Once a battery is charging cheaply overnight on a smart tariff, solar on top mostly displaces cheap stored electricity rather than day-rate electricity, so it adds less than it would on its own. On Octopus Go the overnight rate is 9.5p per kWh against a 33.6p to 37.4p day rate (see how we worked it out). Ask for the solar part of a bundle to be priced separately, and compare that with what the panels would add for your household.

We work through this in our Tesla solar and battery bundle guide and our battery vs solar panels comparison.

Comparing a Powerwall quote with a battery-only alternative

Divide each quote's total installed cost by its usable capacity to compare cost per kWh, and compare that with what the battery would save on your tariff. Habo Energy's 5 kWh EcoFlow STREAM is from £2,499 fully installed, about £500 per kWh, and saves up to about £420 to £490 a year on Octopus Go in the best case (see how we worked it out). A bigger battery can shift more, but only if your household uses that much electricity outside the cheap window. Our cost per kWh guide explains how to compare any two quotes on a level footing.

How to order through Boxt

Start with a quote on the BOXT website, then follow its survey and installation steps. Check what the quote includes, such as any grid-connection fees and, for a solar bundle, scaffolding.

Whichever route you take: consider paying at least part of the cost by credit card where you can, and read up on Section 75 protection before you buy. The GivEnergy administration is a reminder that supplier risk is real.

Just want the savings, not the badge?

Best case up to about £420 to £490 a year on Octopus Go, with best-case payback about 5.1 to 6.0 years (real savings will be lower, see how we worked it out).
