Cheapest green tariff with no exit fee (UK homes)
Find low-cost green electricity tariffs that let you leave without paying an exit fee. We compare whole-of-market options for your postcode, meter type and payment method—then show what to check before you switch.
- See today’s estimated cheapest green, no-exit-fee options for your home
- Understand what “green” means (and what it doesn’t) in UK tariff terms
- Avoid common pitfalls: meter type, standing charges, tracker volatility
Prices and availability vary by region, meter type and payment method. “No exit fee” means the supplier doesn’t charge a termination fee for leaving the tariff—other charges may still apply.
Fast answer: what’s the cheapest green tariff with no exit fee?
There isn’t one single “cheapest green, no-exit-fee tariff” for everyone in the UK. The cheapest option depends on your region (distribution area), meter type (credit, prepayment, smart), payment method (Direct Debit vs pay on receipt) and usage profile. The quickest way to find the lowest estimated cost is to compare tariffs for your postcode and check two things:
1) “Green” claim is clear
Most UK green tariffs are backed by Renewable Energy Guarantees of Origin (REGOs) rather than supplying your home directly from a specific wind/solar farm. Some tariffs also add extra investment in renewables—check the supplier’s fuel mix and policy.
2) No exit fee is confirmed
A tariff can be fixed, variable or tracker and still have £0 exit fees. Always confirm the tariff’s termination fee before applying—especially if you’re choosing a fixed deal.
Editorial note: “Cheapest” should be judged on annual estimated cost (unit rate + standing charge) for your actual usage—not just the lowest unit rate headline.
Compare whole-of-market green tariffs (no exit fee)
Use the form to get a tailored shortlist based on your postcode, meter and contact details. We’ll focus on tariffs that are:
- Green electricity (supplier-backed renewable matching)
- No exit fee (termination fee £0)
- Eligible for UK homes (not business-only contracts)
What you’ll see: estimated annual cost, unit rates & standing charges, tariff type (fixed/variable/tracker), payment method eligibility, and any key conditions we can identify from tariff terms.
Two realistic examples (illustrative only)
Scenario A: Flat (low use), flexible switching
- Assumptions
- Electricity-only, 1–2 bed flat, single-rate meter, Direct Debit. Usage: 1,800 kWh/year. Standing charge: 55p/day. Unit rate: 24p/kWh. Exit fee: £0.
- Estimated annual electricity cost
- Unit cost £432 + standing charge £200.75 ≈ £632.75/year.
Scenario B: House (higher use), watching standing charge
- Assumptions
- Dual fuel (gas + electricity), 3–4 bed, Direct Debit. Electricity: 3,400 kWh/year at 25p/kWh, standing charge 50p/day. Gas: 12,000 kWh/year at 6.2p/kWh, standing charge 30p/day. Exit fees: £0.
- Estimated annual combined cost
- Elec £850 + £182.50 ≈ £1,032.50; Gas £744 + £109.50 ≈ £853.50; Total ≈ £1,886/year.
These examples show why “cheapest” can swing based on usage and standing charges. Your actual quote will use today’s prices for your region and meter, and your own consumption (if provided).

How to choose: tariff types compared (UK, no-exit-fee focus)
No-exit-fee green tariffs commonly fall into three types. This table helps you decide what to shortlist before you look at unit rates.
| Tariff type | Why it can be cheapest | Main risk / trade-off | Who it suits |
|---|---|---|---|
| Variable (often price-cap aligned) | No fixed premium; can be competitive when market prices fall. Usually simple to switch away. | Rates can change (typically with notice). Not protected from future rises. | People who want flexibility and don’t mind rate changes. |
| Fixed (with £0 exit fee) | Protects you if prices rise; occasionally priced below comparable variable deals. | If prices fall, you could overpay. Some fixed deals still have other constraints (e.g., payment method). | Budget planners who want stability but still want the freedom to leave. |
| Tracker (linked to a published index) | Can undercut standard variable rates in falling markets; transparent formula. | Can move frequently; bills can spike. Not ideal if you need predictable costs. | Confident switchers who can tolerate volatility and monitor prices. |
Quick decision checklist
- Do you need price certainty? Consider fixed (but confirm £0 exit fee).
- Do you want maximum flexibility? Variable and many trackers are easier to leave.
- Is your usage low? Standing charge can dominate; compare annual cost carefully.
- Do you have a prepayment meter? Filter for PPM-compatible tariffs—options can be narrower.
- Smart meter? Some green tariffs (especially smart/time-of-use) require it.
Who “cheapest green + no exit fee” is (and isn’t) for
Good fit if you:
- May move home or renegotiate soon
- Want green electricity without commitment
- Like the option to switch when prices change
Not ideal if you:
- Need long-term price lock-in and know you won’t switch
- Prefer “direct-from-generator” sourcing (rare; read terms carefully)
- Can’t meet tariff eligibility (e.g., payment method, meter requirements)
Remember: “No exit fee” doesn’t mean “no costs to leave.” You’ll still pay for energy used up to the switch date, and you may need to give notice depending on the tariff’s terms.
Costs, exclusions and common pitfalls (UK-specific)
To avoid picking a “cheap” green deal that turns out expensive for you, check these areas before you apply.
Standing charge vs unit rate
A lower unit rate can be offset by a higher standing charge (or vice versa). Always compare the estimated annual cost for your usage.
Payment method eligibility
Some tariffs are Direct Debit only. Paying on receipt of bill or by cash/cheque can be priced higher or excluded.
Meter type constraints
Prepayment and Economy 7/time-of-use meters can have fewer suitable deals. Smart/time-of-use tariffs may require a communicating smart meter.
“Green” isn’t one standard
In the UK, suppliers commonly match your electricity use with renewable certificates (REGOs). Some suppliers go further (e.g., additional investment or PPA-backed supply), but claims vary.
Tip: When comparing “green”, look for a clear explanation of how renewable matching works and whether there’s extraity beyond certificates.
No exit fee ≠ no contract conditions
- You may need to give notice or follow a specific switch process.
- Introductory credits or rewards may have terms (and can be removed if you leave early).
- Some tariffs have price change rules (variable/tracker), which affect budgeting.
If you’re moving home
A no-exit-fee tariff can be useful if your move date is uncertain. However, you typically can’t just “take” a tariff to a new address—you’ll open a new account at the new property (often with a different deemed supplier initially) and then choose a tariff again.
FAQs: cheapest green, no-exit-fee tariffs (UK)
Are green tariffs always more expensive in the UK?
Not always. Some green tariffs price very close to standard tariffs, and in some regions they can be similar or occasionally cheaper. The only reliable way to tell is to compare estimated annual cost for your postcode and usage.
What does “no exit fee” actually mean?
It means the supplier does not charge a specific termination/exit fee for leaving that tariff. You still pay for energy you’ve used up to the switch date, and you may need to follow any notice or switching rules in the tariff terms.
Can I get a no-exit-fee green tariff with a prepayment meter?
Sometimes, yes—but availability can be more limited than Direct Debit credit meters. If you’re on prepayment (traditional key/card or smart PAYG), filter for PPM-compatible tariffs and check whether any smart meter requirements apply.
Does a green tariff mean my electricity comes directly from renewables?
Not physically to your home. In Great Britain the grid mixes electricity from many sources. Green tariffs typically mean the supplier matches the amount you use with renewable generation evidence (often via REGOs) and may have additional renewable purchasing policies. Check the supplier’s explanation of how they back their green claim.
Will switching affect my Warm Home Discount or benefits?
It shouldn’t stop you being eligible if you qualify, but schemes and administration can vary by supplier and year. If you currently receive support, check the new supplier’s policy and keep records of your account and meter readings when you switch.
Why are prices different by postcode?
Electricity network costs vary by distribution region, which affects standing charges and unit rates. Suppliers price by region, so the “cheapest” no-exit-fee green tariff in one area may not be the cheapest elsewhere.
Is a tracker tariff a good way to get cheaper green energy?
It can be, but trackers can change frequently and rise quickly. If you need predictable bills, a variable or fixed tariff (with £0 exit fee) may feel safer. If you choose a tracker, understand the published formula/index and how often rates can change.
What information do I need to compare accurately?
At minimum: postcode and whether you pay by Direct Debit, plus whether you have a smart meter or prepayment. For best accuracy, provide annual kWh usage (from a bill or online account) for electricity and gas.

How we assess “cheapest green tariff with no exit fee”
- Filter for UK domestic tariffs available for the user’s postcode/region, meter type and payment method (where that data is provided).
- Filter for no exit fee (termination fee set at £0 for the tariff) based on tariff information/terms available at the time of comparison.
- Identify “green electricity” claims (e.g., renewable matching via REGOs and/or additional renewable purchasing policies), then present the claim transparently rather than assuming all “green” labels are equivalent.
- Rank by estimated annual cost where possible, using your consumption if provided. If not provided, comparisons may use typical consumption assumptions; this can change the “cheapest” result—especially where standing charges differ.
- Show key caveats such as tracker volatility, smart meter requirements, Economy 7 considerations, and eligibility restrictions.
Limitations: Prices change, suppliers update tariffs, and some tariffs have conditions that aren’t fully comparable from headline rates alone. Always read the supplier’s tariff information label / terms before you submit an application.
