Cheapest green energy switch with no exit fee (UK guide)
Find genuinely green energy tariffs you can leave without an exit fee, plus the checks that stop “cheap” quotes turning pricey after you switch.
- Whole-of-market comparison: filter by renewable electricity and £0 exit fee
- UK-specific guidance for prepay, smart meters, Economy 7 and regional prices
- Transparent methodology, realistic examples and common pitfalls (standing charges, tracker rules)
Prices are estimated and vary by region, meter type and payment method. “Green” definitions vary; we explain what to check before switching.
Fast answer: how to find the cheapest green tariff with no exit fee
In the UK, the cheapest “green” tariff you can leave without an exit fee is usually a variable or tracker tariff that includes a renewable electricity claim (often via REGOs). Fixed deals can be green too, but they’re more likely to include exit fees.
Important: “No exit fee” usually means £0 exit fee from the tariff. It doesn’t mean there are no costs at all. Standing charges, unit rates, smart/prepay requirements and tracker rules can still make a deal expensive for your home.
Key takeaways (UK-specific)
- Filter by payment method and meter type: prices differ for credit vs direct debit, smart, prepayment and Economy 7.
- Check standing charges first: a “cheap” unit rate can be offset by high daily charges, especially for low-usage flats.
- Green claims vary: most UK “renewable electricity” tariffs use Renewable Energy Guarantees of Origin (REGOs); some also match supply with generation or invest in new renewables.
- Exit fees are tariff-specific: your current supplier may charge an exit fee if you are on a fixed term. Many people confuse this with the new tariff’s fee.
- Switching is protected: Ofgem rules cover switching standards and complaints handling; you typically won’t lose supply during a normal switch.

What “green” usually means on UK tariffs (and what to check)
REGOs (common)
Many tariffs match electricity supplied with renewable certificates (REGOs). This supports a renewable claim, but doesn’t always mean new renewable generation is built.
Green gas claims vary
“Green gas” may mean a proportion of biomethane, carbon offsets, or a separate green gas product. Compare the detail, not just the label.
Fuel mix disclosure
Suppliers must publish their fuel mix and environmental impact. It’s the quickest way to sense-check marketing claims.
Compare options: what tends to be cheapest (and what to watch)
There isn’t one single cheapest green, no-exit-fee tariff for everyone. Your region, usage, payment method and meter type can change the winner. This table shows typical trade-offs so you can shortlist the right type of tariff.
| Tariff type | Exit fee (often) | Price behaviour | Best for | Watch-outs |
|---|---|---|---|---|
| Variable (standard/green) | Usually £0 | Can change with supplier pricing; often tracks the price cap level | Flexibility; renters; anyone likely to switch again | May not be the absolute cheapest month-to-month |
| Tracker (green option) | Often £0 | Moves regularly (often daily/weekly) vs a published index/cap formula | Comfortable with price movement; willing to monitor | Read the tracker rules (caps, changes, notice periods); budgeting can be harder |
| Fixed (green) | Common (varies) | Unit rates/standing charges fixed for the term (subject to T&Cs) | Budget certainty; households that prefer stability | Exit fees; may miss out if prices fall |
| EV / time-of-use (sometimes green) | Varies | Cheap off-peak, higher peak pricing | EV owners, heat pump homes, battery users (if eligible) | Often needs smart meter; can be costly if you use lots at peak times |
Decision checklist: who it suits
- Renters / moving soon: prioritise £0 exit fee and flexible terms.
- Low usage homes: compare standing charges before unit rates.
- Economy 7: ensure the quote is two-rate (day/night) and matches your night usage.
- Prepayment: only compare tariffs that explicitly support prepay (and check top-up method).
- Budget sensitivity: a variable tariff is usually easier to live with than a tracker.
…and who it doesn’t
- You’re in a fixed deal with a large exit fee: calculate the break cost first (we show how below).
- You want “additional” green impact: the cheapest green tariffs may rely mainly on REGOs; you may prefer a supplier with stronger commitments even if it costs more.
- You need guaranteed monthly bills: trackers can move too often for comfort.
- Your meter setup is unusual: some tariffs don’t support complex meters; always confirm eligibility.
About “cheapest”: always compare estimated annual cost using your usage (kWh) where possible. Comparing unit rates alone can mislead, especially with high standing charges.
Two realistic scenarios (with numbers)
These examples show how a no-exit-fee green tariff can be cheaper or more expensive depending on standing charges, unit rates and usage. They are illustrations only, not a prediction of your bill.
Scenario A: Low-usage flat (electricity only)
- Assumptions
- 1,800 kWh/year electricity. Direct debit. Single-rate meter. Illustrative tariffs below.
- Tariff 1 (Green, no exit fee)
- Unit rate 26p/kWh, standing charge 60p/day.
- Tariff 2 (Green, no exit fee)
- Unit rate 28p/kWh, standing charge 45p/day.
Estimated annual cost
- Tariff 1: (1,800×£0.26)=£468 + (365×£0.60)=£219 → £687/year
- Tariff 2: (1,800×£0.28)=£504 + (365×£0.45)=£164 → £668/year
Even with a higher unit rate, Tariff 2 wins for a low-usage home because the standing charge is lower.
Scenario B: Typical dual fuel household (gas + electricity)
- Assumptions
- 2,900 kWh/year electricity and 12,000 kWh/year gas. Direct debit. Illustrative tariffs below.
- Option 1 (Green electricity, no exit fee)
- Elec 24p/kWh + 60p/day. Gas 6.2p/kWh + 31p/day.
- Option 2 (Green electricity, fixed with exit fee)
- Elec 23p/kWh + 55p/day. Gas 6.0p/kWh + 29p/day. Exit fee £75 per fuel.
Estimated annual cost (excluding any exit fees)
- Option 1: Elec (2,900×£0.24)=£696 + (365×£0.60)=£219 → £915; Gas (12,000×£0.062)=£744 + (365×£0.31)=£113 → £857 → £1,772/year
- Option 2: Elec (2,900×£0.23)=£667 + (365×£0.55)=£201 → £868; Gas (12,000×£0.060)=£720 + (365×£0.29)=£106 → £826 → £1,694/year
Option 2 looks ~£78/year cheaper, but if you might leave early the exit fees (up to £150 here) could outweigh the benefit.
How to use this: treat the math as a template. Replace the kWh usage and rates with your quote details and compare like-for-like (same payment method, same meter type, same region).
Costs, exclusions and common pitfalls (so “no exit fee” stays cheap)
1) Confusing old vs new exit fees
A no-exit-fee tariff means the new tariff won’t charge for leaving. Your current fixed tariff might still charge if you switch away before it ends.
2) Standing charges dominating the bill
Standing charges are paid every day regardless of usage. If you’re a low user, prioritise lower standing charges even if unit rates are slightly higher.
3) Payment method changes
A quote can change if you move from direct debit to pay-on-receipt, or if the supplier doesn’t support your preferred method.
4) Meter and tariff eligibility
Some deals require a smart meter, won’t accept Economy 7, or don’t offer prepay. Always confirm eligibility before you start the switch.
5) Trackers can change quickly
A tracker can be the cheapest at times, but prices can move. Check how often it updates, any cap, and what notice the supplier gives for changes.
6) “Green gas” is not straightforward
Most homes get gas from the grid. Any “green” element is typically via certificates, biomethane proportions, or offsets. Compare the details and decide what you’re comfortable with.
Switching timing: if you’re on a fixed deal, suppliers may allow fee-free switching in the last part of the contract (terms vary). Check your current tariff’s conditions and your latest bill/online account.
FAQs: cheapest green switch with no exit fee (UK)
Is “no exit fee” the same as “no contract”?
Not always. You can be on a contract with terms (like a variable tariff) that still has a £0 exit fee. Always check the tariff information label/summary for both contract length and exit fees.
Can I switch to a green tariff if I’m in debt to my supplier?
It depends on the debt level and the supplier. Some customers may be limited by debt rules or need to agree a repayment plan. If you’re on prepayment, you may have fewer tariff choices.
Does a green tariff mean the electricity to my home is renewable?
Electricity comes from the grid mix. A green tariff usually means the supplier matches your usage with renewable generation certificates (often REGOs) and reports that in its disclosures. Some suppliers go further (for example by supporting new build renewables), but you’ll need to check their fuel mix and policy documents.
Will my smart meter still work after switching?
In most cases, yes, but functionality can vary depending on meter type and supplier systems. If you rely on in-home display readings or half-hourly data, confirm compatibility with the new supplier.
Can I get a no-exit-fee green deal on Economy 7?
Often yes, but you must compare two-rate quotes (day and night rates) and the standing charge. Economy 7 works best if you use a meaningful share of electricity at night (for example storage heaters).
Are the cheapest green tariffs usually direct debit only?
Direct debit often has the widest choice and best pricing, but it varies by supplier. If you need pay-on-receipt or prepay, focus on deals explicitly available for that payment method to avoid inaccurate comparisons.
How long does switching take in the UK?
Switching times can vary. Many switches complete without issue, but timelines depend on meter setup, data matching and whether there are account complications. You should not be left without energy during a normal switch.
If there’s no exit fee, can the supplier still change prices?
Yes on variable and tracker tariffs. No exit fee doesn’t freeze prices. Check how and when prices can change, and whether you’ll be notified.
How we assess “cheapest green” with “no exit fee” (methodology)
Our comparison assumptions
- Location: prices vary by postcode/region; we use your postcode for accuracy.
- Meter type: single-rate vs Economy 7 vs smart/prepay materially changes pricing and eligibility.
- Payment method: direct debit vs other methods can change the available tariffs and rates.
- Cost basis: we compare using estimated annual cost (unit rates + standing charges), using your usage where provided.
What qualifies as “no exit fee”
- The tariff exit fee is £0 (as stated in tariff information / key terms).
- We still flag other restrictions (e.g. tracker mechanisms, eligibility requirements).
- We distinguish between the new tariff’s exit fee and any current supplier exit charges you may face.
What qualifies as “green”
- Tariffs marketed as renewable/green electricity typically backed by REGOs and supplier disclosures.
- We encourage checking the supplier’s fuel mix disclosure and environmental reporting.
- “Green gas” is assessed separately because it can be described in different ways (biomethane share, offsets, etc.).
Limitations: Prices and availability can change. Some tariffs are only available to certain meter types, regions or payment methods. Always read the tariff terms and confirm the rates shown at sign-up.
