Switching providers

Switching energy suppliers is a straightforward process that can save you hundreds of pounds, particularly if you are moving from a standard “Big Six” supplier to a modern, technology-focused energy provider.

Why switch to a smart supplier?

If you have a heat pump, solar panels, or an EV, you need a supplier that understands these technologies. Modern suppliers (like Octopus Energy, OVO, or Good Energy) offer:

  • Specialist Tariffs: Tailored rates for low-carbon homes.
  • Better Data: High-quality apps that show your half-hourly usage and carbon impact.
  • Seamless Export: Automated payments for the electricity you send back to the grid.
  • Renewable Sourcing: Genuine commitment to sourcing electricity from UK wind and solar.

How the switching process works

  1. Compare Tariffs: Use our Tariff Comparison tool or an independent site like Citizens Advice to find the best deal.
  2. Sign Up: Contact the new supplier and provide your address and smart meter details.
  3. The “Switching Service”: Your new supplier will handle everything. They will contact your old supplier to cancel your contract.
  4. Final Reading: Your smart meter will automatically provide a final reading to your old supplier and a starting reading to your new one.
  5. Final Bill: Your old supplier will send you a final bill (and refund any credit) within 6 weeks.

Switching with a Smart Meter

Most modern switches are “seamless” because of the SMETS2 smart meter standard. Your new supplier will automatically take over the communications with your meter.

  • Older Meters (SMETS1): If you have an older smart meter, it may temporarily lose its “smart” functionality when you switch, but most are now being upgraded remotely to work with all suppliers.

The 14-Day Cooling Off Period: By law, you have 14 days to change your mind after signing up with a new supplier. If you cancel during this time, you will remain with your original supplier without any penalty.

Tips for a smooth switch

  • Pay off any debt: It is much harder to switch if you owe your current supplier money (more than £28).
  • Get your refund: If your old account was in credit, ensure the refund is paid into your bank account.
  • Check for exit fees: If you are on a “fixed-term” contract, you may have to pay a small fee (usually £30-£60) to leave early. However, you can switch without fees in the last 49 days of your contract.
