Fast answer: the cheapest green tariff for renters is the one that fits your meter, payment method and time in the property
There isn’t one single “cheapest green energy tariff” for all UK renters because prices vary by region, tariff availability, meter type (including prepayment), and how long you’ll stay. In practice, renters usually get the lowest overall cost by choosing:
If you might move soon (0–12 months)
Prioritise no/low exit fees and reasonable unit rates. A slightly higher rate can be cheaper overall if it avoids a £75–£150+ exit fee when your tenancy ends.
If you’ll stay longer (12–24 months)
Compare fixed green tariffs against tracker/variable options. A fixed tariff can help budgeting, but only if the exit fee and standing charge still work for your usage.
If you’re on prepayment
Your choice can be narrower. Look for prepay-compatible green electricity, check whether you can move to smart PAYG, and compare total cost (unit rate + standing charge), not just “green” branding.
Key takeaway: For renters, “cheapest” is usually about total expected cost over your likely time in the property, plus the practicalities of switching (landlord-managed bills, meter access, and who’s named on the account).
- What counts as a “green” tariff in the UK?
- Most suppliers use renewable certificates (REGOs) to match renewable generation. Some also invest in new renewables or offer additionality. We explain what to check below so you can compare like-for-like.
- Can renters switch energy supplier?
- Often yes, if you’re responsible for paying the energy bills and your tenancy doesn’t include energy. If bills are included or the landlord is the account holder, you usually can’t switch supplier yourself.

Use the form to see available green electricity tariffs for your postcode and setup. We’ll surface options that match your meter and payment method, then you can compare on unit rate, standing charge and exit fees.
Tariff types renters commonly choose
- Fixed: stable prices for a set term (often 12–24 months). Check exit fees if you might move.
- Variable: price can change. Often no exit fee, which can suit shorter tenancies.
- Tracker: price tracks a published formula. Can be competitive but changes more often.
- Green add-ons / pledges: may use renewable matching via certificates; check the supplier’s fuel mix and green claims.
Renters’ eligibility check (quick): You can normally switch if your name is on the energy account and you pay the supplier directly. If energy is included in rent, or the landlord manages the account, ask your landlord/agent first.
How switching works in a rented home
- Confirm you’re allowed to switch (tenancy agreement + who the bill payer is).
- Get your meter details: fuel (gas/electric), smart meter yes/no, prepayment yes/no, Economy 7/10 where relevant.
- Compare on total cost: unit rate, standing charge, exit fee, and tariff term.
- Switch: the new supplier usually handles the process. Take meter readings on switch day.
- Moving home: tell your supplier and provide final readings; you may be able to move the tariff, but not always.

Before you compare: 3 renter-friendly checks
- Bills included? If yes, you may not be able to switch supplier yourself.
- Prepayment meter? Some deals won’t be available; smart PAYG can widen options.
- How long will you stay? Exit fees can outweigh a cheaper unit rate if you move.
Compare green tariff options renters actually face
Use this table to choose a tariff type before you compare prices. “Cheapest” depends on your tenancy length, tolerance for price changes, and whether your meter/payment method restricts you.
| Option | Best for | Watch-outs | Renter tip |
|---|---|---|---|
| Green fixed (12–24 months) | Budgeting; staying put | Exit fees; higher standing charge can hurt low usage | If you might move, filter for low exit fees and check if tariff can move with you |
| Green variable | Flexibility; uncertain move date | Price can rise; “intro” offers can end | Good default if you’re mid-tenancy and want to avoid penalties |
| Green tracker | People comfortable with change; watching the market | Can change frequently; may not suit tight budgets | Set reminders to review the rate and know the tracker formula |
| Green prepayment (PAYG) | PAYG households; topping up weekly/monthly | Limited availability; standing charges still apply | Ask about smart PAYG options and emergency credit rules |
Renter decision checklist
- Account holder: Are you named on the energy account?
- Tenancy length: Are you likely to move before the tariff ends?
- Meter type: Credit, smart, Economy 7/10, or prepayment?
- Payment method: Direct Debit often unlocks more tariffs; PAYG may be restricted.
- Total cost: Compare unit rate + standing charge, not just one headline figure.
- Green claims: Is it 100% renewable electricity? Does the supplier explain how?
Who it suits / who it doesn’t
Likely to suit
- Renters paying bills directly
- Households who want renewable electricity
- People happy to compare exit fees and terms
May not suit
- Bills included in rent (no supplier choice)
- Short, uncertain tenancies with high exit fees
- Homes where you can’t access the meter for readings
Two realistic cost scenarios (with transparent assumptions)
Scenario A: flatshare renter, likely moving in 8 months
Assumptions (electricity only): 2,400 kWh/year usage (≈200 kWh/month), single-rate credit meter, paying by Direct Debit. Comparing over 8 months.
| Illustrative tariff | Unit rate | Standing charge | Exit fee | Estimated 8-month cost |
|---|---|---|---|---|
| Green fixed (12m) with exit fee | 25p/kWh | 55p/day | £100 | ≈ £569 |
| Green variable with no exit fee | 27p/kWh | 50p/day | £0 | ≈ £562 |
Even with a lower unit rate, the fixed tariff can end up more expensive over a short stay once an exit fee is included. This is why renters should model costs over their likely tenancy length.
Math used (illustrative): 8-month usage 1,600 kWh. Standing charge for 243 days. Costs rounded. Rates are examples only and not market offers.
Scenario B: renter in a 1–2 bed, staying 18 months
Assumptions (electricity only): 3,100 kWh/year usage, single-rate credit meter, Direct Debit. Comparing over 18 months.
| Illustrative tariff | Unit rate | Standing charge | Exit fee | Estimated 18-month cost |
|---|---|---|---|---|
| Green fixed (24m) with exit fee | 25p/kWh | 55p/day | £100 | ≈ £1,483 |
| Green variable (assumed flat rate) | 27p/kWh | 50p/day | £0 | ≈ £1,488 |
Over a longer stay, the exit fee is spread over more months, so the decision often comes down to budget certainty (fixed) versus flexibility (variable/tracker).
Math used (illustrative): 18-month usage 4,650 kWh. Standing charge for ~548 days. Costs rounded. Variable prices can change in reality.
Costs, exclusions and common pitfalls (renters)
1) “Green” doesn’t always mean the same thing
Some suppliers match your usage with renewable certificates (REGOs). Others go further by investing in renewable projects. If you care about impact, read the supplier’s explanation of how they supply “100% renewable electricity”.
2) Exit fees can erase a “cheap” deal
Fixed tariffs often include exit fees per fuel. If you might move, look for lower fees or a tariff you can take with you (not always possible).
3) Standing charge matters more for low-usage renters
If you’re out most days, a higher standing charge can outweigh a slightly cheaper unit rate. Always compare total estimated annual cost.
4) Prepayment and complex meters can restrict deals
Prepayment (key/card) and Economy 7/10 tariffs may have fewer green options. If you have a smart meter, ask if you can move to smart PAYG or simplify to a single-rate tariff (where appropriate).
5) Bills included in rent usually means no switching
If your landlord bundles energy into your rent or manages the account, you generally can’t change the supplier. You can still reduce usage and ask about the property’s tariff and efficiency measures.
6) Moving in/out: avoid “deemed” rates surprises
When you move in, you’re often placed on a default (deemed) tariff. Take opening readings, contact the current supplier, and compare quickly so you’re not paying more than you need to.
Important: If you have debt on your energy account, or your landlord/agent is the account holder, switching rules can be different. If you’re unsure, check guidance from Citizens Advice before you switch.
FAQs: cheapest green energy tariffs for renters (UK)
1) Can a tenant switch energy supplier without the landlord’s permission?
If you pay the energy bills and you’re the account holder, you can usually switch without needing landlord permission. If bills are included or the landlord is the account holder, you typically can’t switch supplier yourself.
2) What details do I need to compare tariffs as a renter?
Your postcode, whether it’s electricity-only or dual fuel, your meter type (smart, Economy 7/10, prepayment), your payment method (Direct Debit vs PAYG), and an estimate of your annual usage (kWh) if you have it.
3) Are green tariffs always more expensive in the UK?
Not always. Price depends on wholesale costs, supplier pricing, tariff structure and standing charge. Some green tariffs can be competitive, but you should compare the total estimated annual cost and any exit fees, especially if you might move.
4) Will a green electricity tariff make my gas “green” too?
Usually, no. “100% renewable electricity” normally applies to the electricity supply. For gas, some suppliers offer carbon offsets or limited green gas/biomethane blends. Always read what’s included, because gas decarbonisation is more complex than electricity.
5) I have a prepayment meter — can I still get a green tariff?
Sometimes, yes, but the choice may be smaller. Ask suppliers if they support prepayment for the tariff and whether they offer smart PAYG. Compare both the unit rate and standing charge, as standing charges still apply on PAYG.
6) What if my tenancy agreement says I can’t change supplier?
Tenancy terms vary. In many cases, tenants who pay the bills can choose the supplier, but you may be asked to switch back at the end of the tenancy. If you’re unsure, seek guidance and keep your landlord informed so you avoid disputes during checkout.
7) How fast can I switch, and will my supply be interrupted?
Switching is usually handled by the new supplier and should not interrupt supply in normal circumstances. Timelines vary by supplier and your meter setup. Take meter readings on the day you move in and on switch day to reduce billing issues.
8) If I move, can I take my green tariff with me?
Sometimes. It depends on whether the supplier serves your new address, whether the tariff is still available, and whether your new home has a compatible meter. Always tell your supplier you’re moving, and ask about options to avoid exit fees where possible.

Our methodology (plain English)
When we talk about the “cheapest green tariff for renters”, we mean the tariff with the lowest estimated total cost for a renter’s likely situation, while still meeting basic “green electricity” criteria.
- Total cost focus: estimated cost = unit rate (p/kWh) × usage + standing charge × days + any applicable exit fee (if you leave early).
- Renter constraints: we prioritise tariffs that work with common renter setups: uncertain tenancy length, prepayment meters, and landlord-managed accounts (where switching may not be possible).
- Green criteria: we look for tariffs marketed as 100% renewable electricity and assess the supplier’s explanation (e.g., REGOs, fuel mix disclosure, and any additional environmental commitments).
- Availability reality: tariffs vary by region, meter type and payment method (Direct Debit vs PAYG). What’s cheapest in one postcode may not exist in another.
Limitations: The scenario numbers above are illustrative examples, not live quotes. Market pricing changes and supplier terms can update quickly. Always check the latest tariff information before switching.
