Why Choose Tesla Powerwall?

Tesla Powerwall is one of the world's most advanced home battery systems, designed to help homeowners take control of their energy usage. By storing electricity from your solar panels or the grid, Powerwall allows you to use cheaper energy when you need it most, reducing reliance on rising energy prices. With 13.5kWh of usable storage, intelligent energy management through the Tesla app, and optional backup protection during power cuts, Powerwall delivers energy security, lower bills, and greater independence from the grid.

Is Tesla Powerwall Right for You?

Tesla Powerwall is ideal for homeowners who want to reduce their electricity bills, maximise the value of their solar panels, protect against rising energy costs, or gain backup power during outages. Whether you already have solar panels or are looking to take advantage of off-peak electricity tariffs, Powerwall gives you greater control over when and how you use energy.

How Much Could You Save?

A Tesla Powerwall can help you maximise savings by charging when electricity rates are low and powering your home when rates are higher. Combined with a suitable energy tariff and solar panels, many homeowners significantly reduce their grid electricity usage. Our team will assess your energy consumption, tariff, and property to design a system that delivers the best possible return on investment for your home.

Common questions

Do I need solar panels to benefit from Powerwall?

No. Powerwall delivers strong savings on its own by charging from the grid on low overnight rates and discharging during expensive peak hours. Adding solar increases the benefit further by also storing free daytime generation. EPC can install both together as a complete system.

Which tariffs work best with Powerwall?

Octopus Go and Octopus Intelligent are currently the most popular for consistent home battery savings. Octopus Agile can deliver lower effective rates with more flexibility. EPC will recommend the right option for your usage and configure your system accordingly.

What certifications does EPC hold?

EPC holds MCS certification, Tesla Powerwall certification and Trustmark registration. These are the credentials that matter for a battery installation and we hold all of them on every job we complete.

Is finance available?

Yes. EPC offers flexible finance including 0% options, meaning for many households the monthly saving covers the repayment and the installation is cash-flow positive from month one.

Will it keep my home powered through a blackout?

Yes. Powerwall if installed with a gateway detects grid outages and switches to battery power in under 20ms, fast enough that most appliances will not notice the transition. Your home keeps running on stored energy with no action needed from you.

How much could I realistically save?

Savings depend on your usage, tariff and whether you have solar. Households combining a low-rate overnight tariff with Powerwall typically see £600 to £1,200 per year. EPC will give you a realistic figure for your specific home, not a headline estimate.
