Tip: If you have a recent bill, keep it handy — your annual usage (kWh) helps make comparisons more accurate.

Benefits of switching energy supplier

Switching is a normal part of the UK energy market. The right tariff depends on your meter, household usage and whether you prefer price certainty or flexibility.

Potential bill savings

If your current tariff is no longer competitive, switching may reduce your projected annual cost — especially if you’ve been on a standard variable tariff.

Tariffs to suit your lifestyle

From fixed-rate deals to options that better suit electric heating or off-peak use (where available), you can match tariffs to how you use energy at home.

No interruption to supply

Your gas and electricity keep flowing. Switching is an administrative change between suppliers, with your network staying the same.

Clearer budgeting

Fixed tariffs can help some households plan. You’ll still want to check standing charges, unit rates and any fees before committing.

Manage both fuels together

If you have both gas and electricity, you can compare single-fuel versus dual-fuel options to see what fits best.

More confidence in your choice

A structured comparison helps you avoid missing key details like contract length, price changes, exit fees and payment method restrictions.

How switching energy supplier works (step-by-step)

Most UK home switches follow a similar process. Exact timelines can vary depending on the supplier, your meter setup and whether there are any issues to resolve.

  1. Share your details — postcode and contact info, plus (ideally) your usage in kWh from a recent bill.
  2. Compare tariffs — review unit rates, standing charges, contract terms, payment methods and any fees.
  3. Choose a supplier/tariff — confirm whether you want single fuel (gas or electricity) or dual fuel.
  4. Switch starts — your new supplier arranges the transfer; your existing supplier is notified.
  5. Meter readings — you may be asked to provide opening/closing readings (or smart readings may be used).
  6. Switch completes — you’ll receive final billing from the old supplier and ongoing billing from the new one.

Reminder: You do not need an engineer visit just to switch supplier. Your local network operator remains the same.

What you need to switch energy supplier

You can start with just your postcode, but having the following to hand can improve accuracy and reduce follow-up questions.

Recommended

  • A recent gas/electricity bill (or account screenshot)
  • Estimated annual usage in kWh (gas and/or electricity)
  • Current tariff name and end date (if fixed)
  • Payment method (Direct Debit, prepayment, etc.)

Helpful (if available)

  • Meter type (credit meter, smart meter, prepay)
  • Multi-rate details (e.g., Economy 7) if you use off-peak electricity
  • Your MPAN (electricity) or MPRN (gas) from your bill
  • Any special circumstances (e.g., all-electric home)

Understanding UK energy tariff types

Before you switch, it helps to know the most common domestic tariff types and what to check. Availability depends on supplier, region, meter type and market conditions.

Tariff type Best for What to check
Fixed-rate Households that want price certainty for a set term Contract length, unit rates, standing charges, exit fees, what happens at end of term
Variable Those who prefer flexibility and fewer tie-ins How prices can change, notice periods, whether rates track a cap or internal pricing
Time-of-use / multi-rate Homes that use more electricity off-peak (meter dependent) Day/night rates, how your meter is configured, suitability for your usage pattern
Prepayment Customers who pay-as-you-go using a key/card or smart prepay Top-up methods, emergency credit, standing charges, any smart meter requirements

Compare fairly: Look beyond the headline monthly estimate. Check the unit rate (p/kWh), standing charge (p/day) and any fees that could apply.

Common switching mistakes (and how to avoid them)

Comparing on price alone

A lower unit rate can be offset by a higher standing charge. Compare total estimated annual cost and the tariff details.

Not checking exit fees

If you’re in a fixed term, an exit fee may apply. Confirm your tariff end date and any switching rules.

Wrong meter assumptions

Economy 7, smart meters and prepay can affect which tariffs you can access. Use your bill to confirm meter type.

Skipping usage (kWh)

Without annual kWh, quotes can be less accurate. If possible, use your annual consumption figures rather than spend.

Forgetting payment method

Tariffs can differ by Direct Debit, receipt of bill, or prepayment. Make sure you compare based on how you intend to pay.

Missing key dates

If your fixed tariff is ending, review new options early. Leaving it too late can move you onto a more expensive default tariff.

Switch energy supplier FAQs (UK)

Will my gas or electricity go off when I switch?

No. Your supply continues as normal. Switching is primarily an administrative change and your local network operator stays the same.

How long does it take to switch energy supplier in the UK?

Timeframes vary by supplier and circumstances, but many switches complete within a few weeks. Any issues with meter details or address information can add time.

Can I switch if I have a smart meter or prepayment meter?

Often yes, but availability depends on the supplier and your meter setup. Provide accurate meter details so comparisons reflect the tariffs you can access.

Do I need to contact my current supplier?

Usually no. Your new supplier handles the switching process. You may need to provide meter readings when asked and ensure your account details are correct.

Will I pay an exit fee?

It depends on your current tariff. Fixed deals can include exit fees if you leave before the end date. Check your terms (or your latest bill) before switching.

Is it better to switch gas and electricity together?

Not always. Dual fuel can be convenient, but separate suppliers can sometimes work out cheaper. A whole-of-market comparison helps you evaluate both approaches.
