Average gas and electricity bill for a 1 bed flat with 2 adults

For two adults living in a 1 bed flat you can expect to pay slightly more on your energy bills due to the increased use of hot water and use of heavy load appliances such as tumble dryers and washing machines.

Average gas and electric usage with 2 adult occupants increases your monthly energy bill slightly to between £46 and £73 depending on how expensive your current tariff is. As you can see from the price range you could be paying over a third more (37%) then you need to and do so without reducing your energy usage.

Two adults occupying a one bed flat typically have an annual energy usage of 2,200 kWh for electric and 6,700 kWh for gas. This works out at between £16 to £30 a month for the gas component of your bill and £29 to £43 electricity a month.

The difference in cost to consumers is due to the range of energy tariffs available from energy companies for you to switch to. We found that the ScottishPower 'Help Beat Cancer Fix and Save April 2022 Online v2' tariff was the most expensive at £73 a month whereas you would only be paying £46 if you were an E.ON customer on their 'Fix 1 Year Exclusive March 2020' tariff available through EnergyHelpline.

Energy usage for flats that are not on mains gas and instead use the dual peak and off peak Economy 7 electricity tariffs. Rather than paying a flat price per kWh for electricity you have a cheaper night or off peak price but a more expensive peak daytime price per kWh.

Many flats are on Economy 7 as they are not connected to mains gas and so rely on an electric immersion heater for hot water and night storage heaters. You are only going to benefit from being on an E7 tariff if you make use of the usually 7 hour nightly off peak tariff to heat your water and storage heaters.

Energy comparison sites base there quotes on Economy 7 customers using 58% of their total energy usage in the day peak period and 42% during the cheaper nighttime off peak period.

Cheap economy 7 tariff

From our comparison you can see that depending on the supplier you are with you could be paying a lot more than you need to. We found that whilst Scottish Power were charging 21.307p per kWh on their day rate Together Energy were only charging 12.919p per kWh.

The Green Together Fixed April21 v2 tariff from Together Energy was also cheaper on their night off peak tariff charging 8.664p per kWk compared to 8.950p per kWh on the Help Beat Cancer Fix and Save April 2022 Online v2 tariff from Scottish Power.

The difference in price between Scottish Power and Together Energy for a person living in a small 1 bedroom flat meant that you could save £14 a month. For a larger flat with 1 or 2 bedrooms and 2 adults the saving could be as much as £33 a month.

An economy 7 tariff with British Gas, Eon, EDF or Scottish Power will generally be far more expensive. You should do an energy comparison to see what the cheapest tariff is for your particular usage habits in order to lower your electricity bills.
