Find the cheapest estimated tariff for a one-person home by comparing whole-of-market deals that match your meter type, payment method and usage.
- Tailored for 1-bed flats and small homes (typical single-person use)
- Clear guidance on standing charges, unit rates and tariff types
- Includes realistic examples, pitfalls to avoid and a quick quote form
Estimates vary by region, meter type and payment method. Always check the tariff’s standing charge, unit rates and exit fees before switching.
Fast answer: what’s the cheapest tariff for single occupancy?
There isn’t one universal “cheapest tariff” for a one-person household in the UK. The cheapest for you depends on your region, meter type (smart, standard, Economy 7/10, prepay), payment method (Direct Debit vs prepayment) and how much energy you use.
Single occupancy tip: When you use less energy, the standing charge matters more. A tariff with a slightly higher unit rate can still be cheaper overall if its standing charge is lower (where available).
Key takeaways for 1-person homes
- Compare total estimated annual cost, not just the unit rate.
- Check standing charges (electricity and gas are separate) and whether your region is higher than average.
- Fixed vs variable: fixed gives price certainty; variable can change with the market.
- Smart meters: you don’t need one to switch, but some tariffs are smart-only.
- Exit fees: common on fixed deals; avoid if you may move soon.
What to gather before you compare
- Postcode
- Tariffs and standing charges vary by region (distribution network).
- Meter type
- Standard / smart / Economy 7 / prepay.
- Rough usage (kWh)
- From your bill, in-app account, or a best estimate if you’ve just moved in.
Compare tariffs for a one-person home (whole of market)
Tell us a little about your home and we’ll match you with available tariffs based on your postcode, meter type and preferences. We’ll show the estimated annual cost so you can see what looks cheapest for single occupancy.
Renting? You can usually switch supplier if you pay the energy bills, even if you’re not the homeowner. If your contract says you must use a specific supplier, check first.
How to choose the cheapest tariff for single occupancy
- Start with your likely usage: single occupancy often means lower kWh, so standing charges can dominate.
- Pick your tariff type: fixed (price certainty) vs variable (can go up/down).
- Check your meter: Economy 7 users should compare day/night rates, not a single unit price.
- Look for exit fees and contract length: if you may move, flexible options can be safer.
- Compare total cost: unit rate + standing charge, across electricity (and gas if you have it).

Tariff types compared (what’s often cheapest for single occupancy)
Single-occupancy households can be “standing charge sensitive” because total consumption is lower. This table helps you shortlist what to compare next. Availability varies by supplier, region and meter type.
| Tariff type | Why it can be cheap for 1 person | Watch-outs | Best for |
|---|---|---|---|
| Fixed (12–24 months) | Locks in unit rates/standing charges for the term, helping you budget on a smaller usage profile. | Exit fees may apply; if prices fall you may miss cheaper future deals. | People who value predictable bills. |
| Variable / Standard Variable (SVT) | No exit fees typically; useful if you may move soon or want flexibility. | Rates can change (often in line with the Ofgem price cap for SVTs). | Short stays, renters, anyone avoiding exit fees. |
| Tracker (market-linked) | Can be cheaper when wholesale prices are low; transparent price-setting rules. | Can rise quickly; not ideal if you need stable monthly spending. | Confident bill managers who can tolerate variation. |
| Time-of-use (smart) | If you can shift usage (laundry, dishwashing) off-peak, you may reduce costs even with low overall kWh. | Needs a compatible smart meter; peak rates can be high. | People home at off-peak times; EV owners. |
Decision checklist (single occupancy)
- Standing charge: is it high for your region? (This can outweigh savings on unit rates when you use less.)
- Exit fee: are you likely to move within 12 months?
- Payment method: Direct Debit tariffs can be cheaper than pay-on-receipt or some prepay options.
- Meter setup: Economy 7 only works well if a good share of use is at night.
- Fuel: electric-only flats should focus on electricity rates; dual fuel households should compare both.
Who it suits / who it doesn’t
Often suits you if:
- You live alone in a 1-bed flat or small home
- You want to keep bills predictable
- You don’t want to pay for energy you don’t use
May not suit you if:
- You have highly variable use (e.g., frequent travel) and need maximum flexibility
- You’re on a strict prepay budget and need top-up control
- You rely on night rates but can’t shift enough usage to off-peak (Economy 7)
Two realistic cost scenarios (with assumptions)
These examples are illustrative only. We’ve used rounded figures to show how standing charges and usage interact. Your actual prices depend on your region and tariff.
Scenario A: Electric-only 1-bed flat (single person)
- Annual electricity use: 1,600 kWh
- Tariff 1: 25p/kWh unit rate, 60p/day standing charge
- Tariff 2: 27p/kWh unit rate, 45p/day standing charge
| Estimate | Unit cost | Standing charge | Estimated annual total |
|---|---|---|---|
| Tariff 1 | 1,600 × £0.25 = £400 | 365 × £0.60 = £219 | £619 |
| Tariff 2 | 1,600 × £0.27 = £432 | 365 × £0.45 = £164 | £596 |
Takeaway: For low usage, a lower standing charge can beat a cheaper unit rate.
Scenario B: Small 1–2 bed home with gas heating (single person)
- Annual electricity: 1,800 kWh
- Annual gas: 7,500 kWh
- Compare two dual-fuel options (example rates)
| Estimate | Electric (unit + SC) | Gas (unit + SC) | Estimated annual total |
|---|---|---|---|
| Option 1 | 1,800×£0.26=£468 SC: 365×£0.55=£201 |
7,500×£0.065=£488 SC: 365×£0.30=£110 |
£1,267 |
| Option 2 | 1,800×£0.28=£504 SC: 365×£0.43=£157 |
7,500×£0.068=£510 SC: 365×£0.27=£99 |
£1,270 |
Takeaway: “Cheapest” can be a close call—small differences in standing charges and unit rates can flip the result depending on your actual kWh.
Important: Some suppliers set monthly Direct Debit by smoothing costs across the year. A “cheap” tariff can still feel expensive in winter if your usage rises—review your kWh and your Direct Debit level regularly.
Costs, exclusions and common pitfalls (single occupancy)
These are the most common reasons a “cheap” tariff doesn’t end up being the cheapest for a one-person household.
1) Standing charges outweigh low usage
If you’re out a lot or heat minimally, your annual kWh may be low—so the daily standing charge becomes a bigger share of your bill. Always compare the estimated annual total.
2) Economy 7: day/night split matters
Economy 7 can be good for storage heaters or overnight EV charging, but it can be poor value if most of your use is daytime. Compare using your actual day/night kWh if possible.
3) Payment method changes the price
Some tariffs are priced for Direct Debit. Prepayment and pay-on-receipt can be different. Make sure you compare the same payment method you’ll use.
4) Exit fees (especially if you might move)
Fixed tariffs may include exit fees per fuel. If you’re renting or expect to move, consider whether flexibility is worth a slightly higher rate.
5) “Discounts” that don’t match your usage pattern
A tariff might look cheap if it assumes higher typical use. For single occupancy, focus on your estimated kWh, not average household profiles.
Moving home? Take meter readings on move-in day, contact the current supplier, then compare. You can usually switch once your account is set up (timings vary by supplier).
FAQs
Is there a special “single occupancy tariff” in the UK?
Not usually. Suppliers generally price by region, meter type and payment method, not by number of occupants. Single-occupancy savings mainly come from choosing a tariff that suits lower usage and comparing standing charges carefully.
What usage counts as “single person” for comparisons?
It varies by lifestyle and heating type. As a rough guide, a one-person home may use around 1,500–2,000 kWh of electricity a year in an efficient flat, with gas (if present) often 6,000–9,000 kWh. Your bills are the best source—use annual kWh if you can.
Why does my postcode change which tariff is cheapest?
Energy bills include regional network costs and standing charges that differ across Great Britain (and tariff availability can differ too). So two people using the same kWh can get different results in different areas.
Is Direct Debit always cheaper for single occupancy?
Not always, but it can be. Some tariffs are priced lower for Direct Debit. However, focus on the full estimated annual cost and whether the Direct Debit amount set by the supplier matches your usage pattern.
Can I switch if I’m renting or in a flat?
In many cases, yes—if you’re responsible for paying the energy bills. If your landlord pays the bills, or your tenancy agreement restricts switching, you may need permission. If you’re unsure, check your tenancy paperwork or ask your letting agent.
Do I need a smart meter to get the cheapest deal?
No. Many good fixed and variable tariffs work with standard meters. Some time-of-use deals require a compatible smart meter, but you can still compare and switch without one.
What’s the Ofgem price cap and does it mean I’m on the cheapest tariff?
The Ofgem price cap limits the maximum unit rates and standing charges for standard variable tariffs (and some default tariffs). It doesn’t automatically mean your tariff is the cheapest available—fixed and other deals can be above or below the cap depending on the market.
How long does switching take in the UK?
Switching timelines vary, but many switches complete within a few working days. Your supply won’t be interrupted. If you’re mid-billing cycle, take meter readings and keep confirmations from your old and new suppliers.

Our methodology (plain English)
- We focus on estimated annual cost for your details (postcode, meter type, payment method and usage assumptions), rather than comparing unit rates alone.
- We highlight standing charges because they can dominate bills for low-consumption single-occupancy homes.
- We separate electricity and gas impacts (dual fuel isn’t automatically cheaper; it depends on pricing and your usage).
- We flag eligibility limits such as smart-meter-only tariffs, Economy 7 requirements, and payment method restrictions.
- We call out contractual terms including exit fees, contract length and whether prices are fixed or variable.
Limitations: Prices and tariff availability change. Results are estimates based on the information provided and supplier data at the time of comparison. Always confirm rates, standing charges, fees and terms on the supplier’s tariff information label before completing a switch.
