Fast answer: what’s the cheapest tariff for a single person in 2026?
For a one-person home, the “cheapest” energy tariff is usually the one with the lowest total annual cost for your usage, not necessarily the lowest unit rate. Single-occupancy homes often use less energy, so standing charges can make up a bigger share of the bill.
Most common “winner” for single-person homes: a competitive standard variable tariff (no exit fees) or a short fixed tariff with a low standing charge in your region. The best pick changes by postcode area, meter type (smart vs non-smart; single-rate vs Economy 7) and payment method.
Key takeaways (single person)
- Standing charge matters more when you use less energy.
- Paying by Direct Debit is often cheaper than cash/cheque or prepay (but not always).
- Economy 7 only suits you if you can shift meaningful use to night rates.
- Tracker/variable deals can be cheap but can also rise—check how prices are set and how often they change.
- Exit fees can wipe out small savings if you switch again soon.

Compare whole-of-market tariffs for a one-person home
Enter your details and we’ll match tariffs available for your postcode and meter type. You’ll see estimated annual costs, standing charges, unit rates and key terms so you can choose what fits your budget and risk comfort.
Tenant? You can usually switch if you pay the energy bills and the supplier account is in your name. If you have a landlord-supplied tariff or bills included, you may not be able to change supplier.
How to choose the cheapest tariff (without nasty surprises)
- Compare the total estimated annual cost at your usage, not just p/kWh.
- Check standing charges for both fuels (or electricity-only if no gas).
- Confirm meter compatibility (smart meter, Economy 7 times, prepay rules).
- Look for exit fees and how long the fix lasts.
- Understand price changes on variable/tracker tariffs (frequency and formula).
- Consider customer service and billing (app, support, meter reads).

Two realistic single-person cost scenarios (with numbers)
These examples show why “cheapest” depends on standing charges, unit rates and how much you use. Figures are illustrative estimates (not a quote) and exclude any one-off credits/bonuses. Your actual prices vary by region and tariff.
Scenario A: small flat, electricity-only
- Usage assumption: 1,800 kWh electricity/year (single occupant)
- Tariff 1: 26p/kWh + 60p/day standing charge
- Tariff 2: 29p/kWh + 45p/day standing charge
| Estimated annual cost | Result |
|---|---|
| Tariff 1: (1,800×£0.26) + (365×£0.60) | ≈ £687/year |
| Tariff 2: (1,800×£0.29) + (365×£0.45) | ≈ £687/year |
Takeaway: a lower unit rate can be cancelled out by a higher standing charge at low usage.
Scenario B: one-person, gas + electricity
- Usage assumption: 1,800 kWh electricity/year + 6,000 kWh gas/year
- Tariff 1: Elec 26p/kWh + 60p/day; Gas 7p/kWh + 32p/day
- Tariff 2: Elec 28p/kWh + 45p/day; Gas 6.8p/kWh + 35p/day
| Estimated annual cost | Result |
|---|---|
| Tariff 1 total (elec + gas) | ≈ £1,029/year |
| Tariff 2 total (elec + gas) | ≈ £1,008/year |
Takeaway: when you have gas too, small differences across two standing charges can add up.
Tip: If you don’t know your usage, use your latest bill (kWh). If you’ve just moved in, estimate first, then revisit once you’ve got real readings—single-person usage can vary a lot depending on heating type, home insulation and working-from-home patterns.
Tariff types compared: what’s often cheapest for single occupancy?
This table helps you decide based on how you live. Exact “cheapest” results depend on availability in your area and your meter setup.
| Tariff type | Why it can be cheap for 1 person | Watch-outs | Best for |
|---|---|---|---|
| Standard Variable (SVT) | Often no exit fees; easy to switch again if a better deal appears. | Price can change; may not be the lowest in your region at your usage. | Anyone who wants flexibility and low switching risk. |
| Fixed (6–12 months) | Can undercut variable pricing; budget stability for the term. | Exit fees may apply; “cheap” unit rate can hide higher standing charge. | You want predictable bills and expect to stay put. |
| Tracker / variable linked tariff | Can be lower at times, especially if wholesale falls. | Can rise quickly; may change daily/monthly; you carry more price risk. | Comfortable with price movement and monitoring. |
| Time-of-use (incl. Economy 7) | Can be cheaper if you move usage to off-peak (e.g., storage heating, night charging). | Day rates can be high; Economy 7 times vary; not ideal if you use most power in the evening. | Homes with storage heaters or consistent overnight use. |
Decision checklist (quick)
- If you use low energy, prioritise lower standing charges.
- If you might move soon, avoid big exit fees on long fixes.
- If you have Economy 7, check your split (night vs day kWh).
- If you’re on prepay, compare prepay-specific offers (eligibility differs).
- If bills are tight, consider budgeting features and billing reliability.
Who it suits / who it doesn’t
Often suits
- One-person flats with modest usage
- People who want predictable monthly payments
- Anyone able to pay by Direct Debit
May not suit
- Very short stays (exit fees risk)
- Economy 7 homes with mostly daytime use
- Households with bills included (no switching control)
Costs, exclusions and common pitfalls (single person)
A tariff that looks cheap on a headline rate can cost more once you account for eligibility and how you actually use energy.
1) Standing charges dominate low usage
If you’re out a lot or keep heating low, standing charges can be a large share of your bill. Compare total cost, not just p/kWh.
What to do: when comparing tariffs, keep your estimated annual kWh realistic for one person—then sanity-check the impact of standing charges.
2) Economy 7 can backfire
Economy 7 can be good for storage heaters, but if most of your usage is at peak times, the higher day rate can outweigh night savings.
What to check: your day/night split on your bill (kWh). Ask how your supplier sets off-peak times.
3) Direct Debit vs other payment methods
Some suppliers price differently for Direct Debit, pay-on-receipt-of-bill, or prepay. A “cheap” online deal might require Direct Debit.
What to do: compare using the payment method you’ll actually use—then see if switching payment method unlocks a better price.
4) Exit fees and short stays
If you rent and might move, exit fees can wipe out the benefit of a fixed tariff.
What to do: weigh a no-exit-fee variable tariff against a fix. Consider how likely you are to switch again within the term.
5) Dual fuel isn’t always cheaper
Some suppliers offer dual fuel discounts or convenience, but the cheapest electricity and cheapest gas aren’t always with the same supplier.
What to do: compare both as dual fuel and separately if your setup allows. Consider admin simplicity too.
6) One-off credits can distort “cheapest”
Intro credits or cashback can make a tariff look cheaper in year one. If you plan to stay longer, check the ongoing rates and what happens after the offer ends.
What to do: compare the underlying unit rates/standing charges and the tariff end date, not just a headline saving.
Important: If you have a complex meter (e.g., multiple registers), restricted meter, or you’re unsure whether you have gas connected, it’s worth checking your latest bill or asking your current supplier before switching.
FAQs: cheapest energy tariff for one person (UK)
Is there a special “single person energy tariff” in the UK?
Usually not. Suppliers price by meter, region and payment method—not by the number of occupants. For single occupancy, choosing the cheapest tariff is mainly about matching rates and standing charges to low/medium usage.
What’s a reasonable annual kWh estimate for one person?
It varies by heating type and lifestyle. As a rough starting point, many one-person homes fall somewhere around 1,500–2,500 kWh/year for electricity. If you have gas central heating, gas use could be several thousand kWh/year (higher in winter). Use your bill if possible for accuracy.
Why does my postcode change the price?
Energy standing charges and unit rates can vary by region because of differences in network costs and regional pricing. That’s why a tariff that’s cheap in one area may not be the cheapest elsewhere.
Is it cheaper to have gas + electricity with the same supplier?
Sometimes, but not always. Dual fuel can be convenient and may include bundled pricing. However, the cheapest option can be separate suppliers, depending on what’s available for your meter and address.
Can I switch if I’m renting?
In many cases, yes—if you’re the bill payer and the account is in your name. You usually can’t switch if energy is included in rent or your landlord controls the supply contract. If you’re unsure, check your tenancy agreement and current bills.
Do smart meters unlock cheaper tariffs?
They can. Some tariffs (especially time-of-use) require a smart meter. But you can still get competitive fixed or variable deals without one. The best approach is to compare what’s available for your current meter setup.
Will switching interrupt my supply?
Normally, no. Switching supplier is an administrative change. You should keep the same physical supply and your energy won’t be cut off just because you switch.
What if I’m on prepayment (Pay As You Go)?
Prepay customers can still compare and switch, but tariff availability and pricing can differ. If you have debt on the meter, it may affect switching. Compare prepay-eligible tariffs specifically and check any conditions.

How we assess “cheapest” for a single person
When we use the term cheapest on this page, we mean: the lowest estimated annual cost for a given set of assumptions, considering unit rates (p/kWh), standing charges, and common tariff features that affect real-world bills.
- Region: prices vary by postcode/network area, so comparisons should be postcode-based.
- Meter type: single-rate, Economy 7, smart, and prepay can change eligibility and pricing.
- Payment method: Direct Debit vs other methods can affect the price offered.
- Tariff terms: we check contract length, exit fees, and whether prices can change (variable/tracker).
- Usage profile: single-person homes are often low-to-medium usage, making standing charges more influential.
Limitations: This guide is educational and cannot list a single nationwide “cheapest tariff” because prices depend on your address, meter and eligibility. Supplier availability and tariffs can change, and some deals may be limited to new customers or specific meter setups.
