Can I switch energy supplier without paying exit fees in the UK?
Yes—often. Whether you can switch without an exit fee depends on your tariff type, how close you are to the end date, and whether your supplier has changed your terms or prices. This guide explains the rules in plain English and helps you check your own situation.
- Fixed tariffs may have exit fees, but many waive them in the last 49 days of the fixed term.
- Variable (standard) tariffs usually have no exit fees.
- If your supplier puts prices up (outside agreed changes), you may be able to leave without a fee—check the notice.
Exit fees and waiver rules vary by supplier and tariff. Always check your contract/T&Cs and your latest bill before switching.
Fast answer: when you can switch without paying an exit fee
In the UK, you can often switch energy supplier without paying an exit fee, but it depends on your tariff type and timing:
1) Variable / Standard tariff
Usually no exit fee. You can switch at any time (subject to normal switching timescales).
2) Fixed tariff
Exit fees are common, but many tariffs waive fees if you switch in the last 49 days of the fix.
3) Supplier changes terms/prices
You may be able to leave without penalty, but you must follow the supplier’s notice and deadline.
Quick check: Look at your latest bill or online account for “Tariff name”, “Tariff end date”, and “Exit fee”. If it’s unclear, ask your supplier to confirm in writing before you switch.
Key takeaways
- Exit fees are a tariff feature, not a rule that applies to every switch.
- 49-day rule: fixed-term customers can usually switch without an exit fee during the final 49 days (check your tariff terms).
- Don’t cancel directly unless your supplier tells you to—start the switch with the new supplier to avoid gaps and billing confusion.
- Debt, prepayment and meters matter: some tariffs and supplier policies can affect your options.
If you’re in a rush
If your fix ends soon, you can often lock in a new tariff now without paying an exit fee (when you’re inside the waiver window). We’ll highlight this when you compare.
Check deals for your postcodeCompare tariffs first, then check the exit fee impact
A good switch decision is usually a balance of:
- Exit fee (if any) on your current tariff
- Estimated new unit rates & standing charges on the tariff you want
- How long you plan to stay in the property (or on that tariff)
- Your meter & payment type (credit, direct debit, prepay; smart meter compatibility)
Two realistic examples (with numbers)
Scenario A: Fixed tariff, inside 49 days
Assumptions: You have 35 days left on a fixed tariff with a £75 exit fee stated in the contract; supplier waives exit fees in the last 49 days (common practice). You’re comparing a new fixed tariff estimated to be £12/month cheaper for similar usage.
- Expected exit fee
- £0 (waived inside the window, subject to your tariff terms)
- Estimated benefit
- About £12/month once the switch completes
Why it works: you avoid the penalty and start paying the new rates when your switch completes.
Scenario B: Fixed tariff, outside waiver window
Assumptions: You have 5 months left on a fixed tariff; exit fee is £100 per fuel (£200 for gas + electricity). A new tariff looks £25/month cheaper (estimated) for your household.
- Estimated saving over 5 months
- £25 × 5 = £125
- Estimated exit fees
- £200
- Net impact (estimate)
- £125 - £200 = -£75 (switching early may cost more)
What to do: consider waiting until you reach the 49-day window, or look for a tariff where the benefit clearly outweighs the fee.
Figures are illustrative estimates. Your result depends on actual usage (kWh), regional standing charges, payment method and the exact exit fee terms on your tariff.
Good to know: If you’re moving home, you’ll typically close your account at the old address (no “switch”) and set up supply at the new address. Exit fees can still apply depending on your tariff—ask your supplier how they treat moves.

Exit fee rules: a practical comparison
This table is a quick way to work out whether you’re likely to pay an exit fee when switching. Always confirm your tariff’s exact terms (fees can vary by supplier and product).
| Your situation | Is an exit fee likely? | What to check before you switch |
|---|---|---|
| Standard Variable Tariff (SVT) | Usually No | Any special conditions (rare) and whether you owe a balance. |
| Fixed tariff, more than 49 days left | Often Yes | Exit fee amount (per fuel), whether it’s pro-rata, and if moving home changes anything. |
| Fixed tariff, within last 49 days | Usually No (waived) | Exact end date and your supplier’s waiver wording (start the switch within the window). |
| Supplier notifies a disadvantageous change (e.g., price rise outside agreed structure) | Often No (if you act in time) | The notice, deadline, and whether the change counts as “disadvantageous” under your terms. |
| Prepayment (PPM) customer switching | Depends | Debt level, meter type (smart/traditional), and whether the new supplier accepts your meter and payment method. |
Decision checklist: switch now or wait?
- Find your end date: are you within 49 days of a fixed term ending?
- Confirm the fee: is it per fuel (gas + electric) and what’s the total?
- Estimate the break-even: will the new tariff’s estimated monthly benefit outweigh the fee before your fix would end?
- Check payment method: some tariffs are Direct Debit only (pricing may differ).
- Check meter compatibility: especially for Economy 7/10, smart meters and prepay.
Who switching early tends to suit
- Households on SVT (no fee) wanting a fixed deal
- Fixed customers inside the 49-day window
- People who can clearly beat the fee before the fix ends (after estimating usage)
Who it may not suit
- Fixed customers far from end date with high exit fees
- Anyone about to move (timing and final bills can complicate it)
- Prepay customers with debt above a supplier’s switching threshold
Costs, exclusions and common switching pitfalls
Exit fees aren’t the only thing that can affect the cost (or smoothness) of switching. These are the most common UK gotchas we see.
Exit fee per fuel
Some tariffs charge separately for gas and electricity. Example: “£75 exit fee” might mean £75 each (total £150) for dual fuel—check the wording.
Timing vs the waiver window
If you’re relying on the final-49-days rule, start the switch inside the window. Waiting until the last minute can backfire if details need confirming.
Estimated bills vs real usage
Comparison results are estimates based on inputs and tariff rates. If your actual kWh use is higher/lower, your break-even point (vs exit fee) shifts.
Prepayment meters and debt
If you’re on a prepayment meter, you may still be able to switch, but supplier policies vary. Debt on the meter can limit switching options.
Caveat: If you owe money to your current supplier, you may need to clear the balance or agree a repayment arrangement before switching is accepted.
Moving home vs switching
If you’re moving, you typically provide final meter readings and close the account at your old address. A “switch” is usually for staying at the same address.
Tip: Ask your supplier whether your fixed tariff can be transferred to the new property (and whether exit fees apply if you can’t).
Avoid these common mistakes
- Don’t cancel your supply unless instructed—initiate the switch with the new supplier to avoid supply/billing issues.
- Take meter readings on switch day (and keep a photo) to reduce the risk of estimated final bills.
- Check tariff type (single-rate vs Economy 7/10) before choosing a new tariff—wrong tariff structure can raise costs even with lower unit rates.
- Confirm any discounts/bonuses are real and comparable (e.g., limited-time discounts vs ongoing rates).
FAQs on switching without exit fees (UK)
Do all energy tariffs have exit fees?
No. Exit fees are most common on fixed-term tariffs. Standard variable tariffs usually don’t have exit fees, but always check your tariff information and terms.
What is the “49-day” rule for exit fees?
Many UK fixed tariffs allow you to switch without an exit fee in the final 49 days of the fixed term. This is designed to let you shop around before your fix ends. Your supplier should show your tariff end date and any fees in your account or on your bill—confirm if unsure.
If my supplier puts prices up, can I leave without paying exit fees?
Often yes, if the change is considered disadvantageous under your contract and you act within the timeframe set out in the notice. Price cap changes and other “built-in” changes may be treated differently. Read the notice carefully and keep a copy.
Can my current supplier block me from switching if I owe money?
In some cases, debt can affect switching—especially for prepayment meters. You may need to repay what you owe or agree a repayment plan. If you’re struggling, contact your supplier early and ask about support options.
Will switching affect my smart meter?
Usually you can switch with a smart meter, but functionality can vary by supplier and meter setup. In some cases, a smart meter may temporarily operate like a traditional meter (for readings) after you switch. Your new supplier can confirm compatibility.
Do I need to contact my current supplier to switch?
Typically no. When you sign up with a new supplier, they handle the switching process. You may want to contact your current supplier only to confirm the exit fee and end date so you can make a confident decision.
Can tenants switch energy supplier without exit fees?
Often yes, if you’re responsible for paying the energy bills and your tenancy allows it. Exit fees depend on the tariff, not whether you own the property. If bills are included in rent, you usually can’t switch.
Can I switch just gas or just electricity?
Yes, but if you’re on a dual-fuel fixed tariff, check whether exit fees apply separately for each fuel. Also compare the full cost—sometimes a combined deal is simpler, but not always cheaper.

How we assess “switching without exit fees”
We built this guide around UK regulator and consumer guidance, plus the most common tariff structures in the domestic market. For the examples, we use simple break-even maths:
- Net impact estimate = (estimated monthly difference × months until tariff end) - exit fee(s)
- We assume the household’s usage profile stays broadly similar during the comparison period.
- We treat exit fees as a one-off cost and show where they may be waived (e.g., within the final 49 days on many fixed tariffs).
Limitations: Suppliers can structure exit fees differently (per fuel, per account, or differing by product). Standing charges vary by region and can change. Always verify your specific tariff terms and your supplier’s latest communications.
