Tesla can supply electricity in Britain. Can you switch yet?

Tesla has cleared a major regulatory step. The practical question for Scottish homeowners is what it will offer—and when.

The position today

Ofgem granted Tesla Energy Ventures Limited a licence to supply electricity to homes and businesses in Great Britain, effective 11 March 2026. That permits Tesla to enter the market. It does not mean a household tariff is on sale. As of 27 September, we have found no published Tesla UK domestic tariff, price list, sign-up route or confirmed launch date.

What has actually changed?

Tesla already sells Powerwall batteries in Britain. The new licence gives a separate Tesla company authority to sell electricity directly to domestic and business customers in England, Scotland and Wales. It covers electricity, not gas. Ofgem says the company must meet the same supplier duties on billing, customer protection and fair treatment as other licensed suppliers.

Why does this matter to a solar buyer?

A supplier that also makes batteries, software and electric cars could potentially coordinate when a household imports cheap electricity, uses stored solar power or exports energy. Tesla already describes a virtual power plant in which eligible Powerwalls support the grid and owners may receive rewards. But the terms of any future British Tesla electricity tariff—including import and export rates, standing charge, Powerwall or vehicle eligibility, and any payment for flexibility—remain unannounced. Do not assume its US arrangements will be copied here.

Should you wait before buying panels or a battery?

A licence is not a tariff comparison. If your proposed system is financially sound on current prices and realistic generation, Tesla's future offer can be assessed when its actual terms appear. If a quote only looks attractive because it assumes a generous future Tesla tariff, ask for the numbers to be redone using a tariff you can join today.

For a battery, ask how easily you can change supplier, which smart tariffs and external control services it supports, whether exports are permitted, and how the warranty treats extra cycling. A strong system should retain useful options as suppliers compete.

What to watch next

  • A confirmed launch date and public household sign-up.
  • Import rates, standing charge and export payment for a Scottish postcode.
  • Whether Powerwall, a Tesla vehicle or solar panels are required.
  • How any virtual power plant controls the battery and shares revenue.
