UK guidance on how to change domestic energy providers.

This page provides formal guidance for domestic consumers in the United Kingdom on the process, rights, and requirements for switching energy suppliers. The ability to switch gas or electricity suppliers is protected under consumer law and regulated by Ofgem, the UK energy market regulator.

This guidance applies to all household energy accounts and aims to ensure that consumers understand how to switch suppliers safely, efficiently, and without risk of disruption to energy supply.

Your Right to Switch

All domestic energy consumers in the UK have a legal right to switch suppliers at any time.

Key consumer protections include:

  • No disruption to energy supply during the switch
  • No exit fees if you’re on a standard variable tariff
  • A cooling-off period of 14 calendar days after agreeing to a new contract
  • Price comparison services must be free, impartial, and transparent

Switching allows customers to find better tariffs, improve service quality, or opt for greener energy sources.

When You Can Switch

You can initiate a switch:

  • At any time if you are on a standard variable tariff
  • Up to 49 days before the end of a fixed-term tariff without paying exit fees
  • After the expiration of a fixed-term deal, when you revert to a default tariff

You do not need permission from your current supplier to begin the switch process.

How to Switch Suppliers

The switching process is straightforward and typically managed by the new supplier, who coordinates with your current supplier to complete the transfer.

Step-by-Step Process:

Compare Energy Tariffs

  • Use approved comparison tools or supplier websites
  • Compare unit prices (kWh), standing charges, and estimated annual costs
  • Review tariff terms such as fixed vs variable rates, exit fees, and renewable content

Select a New Supplier

  • Choose your preferred tariff and complete an application online or by phone

You will be asked for information including:

  • Full name and address
  • Meter readings
  • Current supplier and tariff details
  • Payment preferences (e.g. direct debit, prepayment)

Cooling-Off Period Begins

  • You have 14 days to cancel the switch with no penalty
  • No work will be carried out until this period ends unless you request early activation

Final Meter Reading and Account Closure

  • Your new supplier will request a final meter reading
  • Your old supplier will use this to generate your final bill

Switch Completed

  • The switch is usually completed within 5 working days (for standard credit meters)
  • You’ll receive confirmation from your new supplier and a final bill from your old one

Special Situations

Prepayment Meters

You can still switch suppliers if you have a prepayment meter, although tariff options may be more limited. Some suppliers offer prepayment tariffs or may offer to upgrade your meter.

Smart Meters

If you have a smart meter, ensure that the new supplier can support your device. If not, it may temporarily function as a traditional meter, requiring manual readings.

Tenants and Shared Homes

  • Tenants can switch if they pay the energy bill directly
  • If the landlord pays the bill, only they can initiate a switch
  • Always check your tenancy agreement for energy clauses

What If You’re in Debt?

You can still switch suppliers if:

  • You owe less than £500 on a prepayment meter, and
  • You’re switching to a supplier that agrees to take on the debt

For standard credit accounts, your current supplier may block the switch if there is an outstanding balance. It is advisable to contact them and resolve any disputes before attempting to switch.

What Happens to Your Energy Supply?

Your electricity and gas will not be interrupted during the switch. The physical supply continues through existing infrastructure.

The only changes are:

  • Who you pay
  • The rate you pay
  • Customer service provider

Your Rights During the Switch

Under Ofgem rules, you are entitled to:

  • Accurate, clear information before and during the switch
  • A final bill within 6 weeks of your switch date
  • Resolution of complaints through the supplier’s internal process and, if needed, the Energy Ombudsman

If the switch takes longer than 5 working days (after the cooling-off period), you may be eligible for:

  • £30 automatic compensation from the new supplier

Avoiding Misleading Practices

Always ensure:

  • You are dealing with a licensed energy supplier
  • Any third-party switching services are Ofgem-accredited
  • You verify tariff terms before accepting a contract over the phone or online

To switch energy suppliers safely and effectively:

  1. Use an Ofgem-accredited price comparison tool to review tariffs based on your usage
  2. Check your current tariff and contract end date to understand any potential exit fees
  3. Take a meter reading when initiating the switch
  4. Keep a copy of all correspondence and your new contract terms
  5. Monitor your account to ensure the switch is completed within 5 working days after the cooling-off period
  6. Report unresolved issues to the Energy Ombudsman if necessary
