Discover why standing charges matter most when living alone, and learn how to save hundreds on energy bills as a single occupant in 2026.
Contact UsThe single occupant energy cost paradox explained
Fixed daily costs make up a larger portion of bills for single occupants compared to families.
Most tariffs are designed for family homes with higher usage, not single occupants.
Staying on expensive default or variable tariffs instead of switching to better options.
For single-occupancy homes, choosing the wrong energy tariff can cost £300–£500 per year unnecessarily. The combination of high standing charges, wrong tariff type, and staying on default deals creates a perfect storm of overpayment. Single occupants who don't compare properly often subsidize cheaper deals for larger households.
Why standing charges matter most for single occupants
These fixed daily costs apply regardless of how much energy you use, making them the dominant factor for low-usage homes.
Standing charges are the same every day, regardless of your energy usage. £1/day = £365/year fixed cost.
Even if you use zero energy for a day, you still pay standing charges. They're completely fixed.
Standing charges vary significantly by UK region, from 20p/day to 50p/day for the same supplier.
A tariff with the lowest unit rate is often not the cheapest option for one person. A tariff with slightly higher unit rates but much lower standing charges can save single occupants hundreds annually. For example: Tariff A (25p/kWh + 25p/day) vs Tariff B (28p/kWh + 15p/day). For low usage, Tariff B is often cheaper despite higher unit rates.
Realistic cost expectations based on property type
| Property Type | Typical Annual Cost | Key Considerations |
|---|---|---|
| Studio / 1-bed flat (electric only) | £650 – £900 | Standing charges dominate. Electric-only tariffs critical. |
| 1-bed flat (gas + electric) | £750 – £1,050 | Balance of gas and electricity standing charges matters. |
| Small 1-bed house | £850 – £1,200 | Slightly higher usage, but standing charges still key. |
| Electric-only with storage heaters | £700 – £1,100 | Economy 7 tariff essential. Wrong tariff = much higher. |
| Prepayment meter property | £800 – £1,150 | Typically 5-10% higher than credit meters. Comparison vital. |
Choosing the wrong tariff can easily push costs far higher. These ranges assume competitive, single-occupant-optimised tariffs. Staying on default variable tariffs or choosing family-focused deals can add £200-£400 to these annual costs. The difference between the best and worst tariffs for single occupants is often 30-40% of the total bill.
The characteristics of ideal single-occupant energy deals
Priority number one for single occupants. Lower fixed costs mean lower bills.
Competitive but not necessarily lowest unit rates. Balance with standing charges.
Flexibility to switch without penalty if circumstances change or better deals appear.
12-month or shorter contracts that match single occupants' potential mobility.
For single-occupancy homes, the cheapest energy supplier offers tariffs suitable for low usage households. This means optimising the balance between standing charges and unit rates, not simply offering the lowest unit rate. The cheapest supplier for a family of four is often different from the cheapest supplier for a single occupant in the same postcode.
Choosing the right tariff type when living alone
Important factors for different living situations
Electricity standing charges are higher than gas. Low standing charge tariffs critical for single occupants.
Often more expensive for single occupants who don't use 35-40% electricity overnight. Higher standing charges.
Many green tariffs cost the same as standard. Fixed green tariffs often beat variable standard ones.
Avoid these costly errors when comparing energy
Focusing only on p/kWh rates while ignoring high standing charges that dominate single occupant bills.
Not realizing standing charges can be 40-60% of total cost for single occupants living alone.
Remaining on expensive default variable rates instead of switching to cheaper fixed deals.
Using average family consumption figures instead of realistic single occupant usage patterns.
Assuming green energy is more expensive, missing deals that cost the same as standard tariffs.
Staying with the same supplier for years without checking if better single-occupant deals exist.
These mistakes are why single occupants often overpay by £300-£500 annually. The combination of wrong tariff selection, focus on unit rates over standing charges, and staying on default deals creates systematic overpayment. Single occupants who don't compare specifically for their low-usage situation effectively subsidize cheaper deals for larger households through their higher per-unit costs.

For single occupants, standing charges often matter more than unit rates due to lower overall usage.
The cheapest tariff for single occupants is different from family tariffs due to different consumption patterns.
Proper comparison can save single occupants £150–£400 annually by escaping family-focused tariffs.
