What is the energy supplier loyalty penalty in the UK?

The term loyalty penalty describes the extra amount some households pay by staying with the same supplier or tariff, compared with households who switch or renegotiate regularly. It can show up as a higher unit rate, a higher standing charge, or simply missing out on cheaper tariffs.

Why it happens

Many customers roll onto default rates after a fixed term ends, or simply never review their tariff. Suppliers may reserve their most competitive deals for new customers or online-only sign-ups.

What it can look like

A direct debit increasing, bill estimates drifting upwards, or paying a higher rate than similar homes in your region. The difference can be bigger for higher-usage households.

When to act

If your fix is ending, your payments changed, you’ve moved home, or you haven’t compared for 12 months, it’s a good time to check the market.

How to switch energy supplier in the UK (without stress)

Switching is typically straightforward for most UK households: you choose a tariff, the new supplier arranges the transfer, and your supply usually continues without interruption. Your meter and pipes/wires stay the same — only the billing supplier changes.

  1. Compare your options by postcode and meter type (standard, smart, Economy 7, prepayment).
  2. Check tariff details: unit rate, standing charge, exit fees, payment method, and whether it’s fixed or variable.
  3. Start the switch with your chosen supplier — they handle the process and contact your current supplier.
  4. Take meter readings when requested (or your smart meter may send readings automatically).
  5. Receive final bill/credit from your previous supplier and begin paying the new one.
Good to know

You can often switch even if you’re in debt to your current supplier, but the options depend on your circumstances (particularly with prepayment meters). If you’re unsure, submit the form above and we’ll point you in the right direction.

What you need to switch (and what you can skip)

Having the right details to hand helps you compare accurately — but you don’t need to overcomplicate it.

Useful information Why it matters Where to find it
Postcode Shows regional price differences and available tariffs Your address
Current supplier & tariff name Helps identify if you’re on an SVT or out-of-contract deal Bill, app or online account
Estimated usage (kWh) Improves comparison accuracy vs relying on generic estimates Annual statement or recent bills
Meter type (smart/standard, Economy 7, prepayment) Some tariffs are only available for certain meters Meter box, bill or supplier account
MPAN/MPRN (optional) Can help match your supply details faster Electricity/gas bill
Don’t have bills to hand?

That’s common, especially if you’ve moved recently. Submit the form with your postcode and contact details and we’ll help you identify what you’re currently on and what you could switch to.

Common switching mistakes that keep the loyalty penalty in place

Avoid these and you’ll usually get a more accurate comparison and a smoother switch.

Comparing on monthly direct debit only

Monthly payments can be adjusted to pay off credit/debit balances. For a true comparison, focus on unit rates, standing charges and estimated annual cost.

Forgetting exit fees

Some fixed tariffs include early exit fees. If you’re close to the end date, it may be cheaper to wait — or choose a deal that still stacks up after fees.

Not checking meter type

Economy 7 and prepayment tariffs can be priced differently. Ensure you’re comparing like-for-like for your meter and usage pattern.

Using outdated usage figures

Household changes (WFH, new baby, EV, heat pump) can change your usage materially. Updated estimates improve your results and reduce bill shocks.

FAQs: loyalty penalty and switching supplier

Can I switch energy supplier if I’m on a standard variable tariff (SVT)?

Yes. Many households on SVTs can switch without exit fees. Comparing rates can help you see whether a fixed deal or another variable option is better for your home right now.

Will my gas/electricity go off when I switch?

No — switching supplier doesn’t usually interrupt your supply. Your network (pipes and wires) stays the same; only the company billing you changes.

Is it worth switching if prices are high?

It can be. Even in a high-price market, tariff structures differ by supplier and region. Switching may reduce costs, improve billing/service, or give you more certainty with a fixed term.

Can I switch if I have a smart meter?

In most cases, yes. Your smart meter should keep working, though smart functionality can vary depending on meter model and supplier systems. If you’re unsure, we’ll help you check.

What about exit fees on fixed tariffs?

Some fixed deals include exit fees if you leave before the end date. When comparing, consider the overall cost difference versus your current tariff and how close you are to the end of your term.

How often should I compare to avoid the loyalty penalty?

A sensible rule is every 12 months, and also whenever your fixed tariff is ending or your payments change unexpectedly. Regular checks help you avoid drifting onto a higher-cost option.
