Electricity consumption varies widely between UK homes, even when they are similar in size. The number of people living in the property, heating system, insulation, appliances and daily habits can all affect how much electricity a household uses.

For an 80, 100 or 150 m² home, looking at annual and daily electricity consumption can provide a useful benchmark for understanding whether your usage is typical and where you may be able to reduce it.

In this guide, we’ll look at average electricity usage in the UK, how much electricity homes of different sizes typically use, how to convert annual consumption into daily kWh, and which factors can cause your electricity use to be significantly higher or lower.

How Can You Estimate Your Home’s Electricity Consumption?

The average UK household does not typically use 10,000 kWh or more of electricity per year. Recent government data shows that electricity consumption is considerably lower.

In 2024, the median domestic electricity consumption in England and Wales was 2,500 kWh per year, while the mean was around 3,300 kWh. The median is often more useful for understanding typical household usage because unusually high-consuming properties can push the mean upward.

That works out to approximately:

2,500 kWh per year ÷ 365 = 6.8 kWh per day

A household using around 7–10 kWh per day can therefore be within a normal range, depending on its size, occupancy, heating system and appliances. Larger homes or properties with substantial electrical heating can use considerably more.

This is also why there is no single figure for “normal” electricity consumption. A 150 m² house with gas central heating may use less electricity than a much smaller all-electric home.

Average Power Consumption of Common Appliances (UK Estimates)

Different household appliances require different amounts of electrical power. The following ranges provide a general reference for common appliances in UK homes. Actual power ratings vary by model, size and efficiency.

These figures show power ratings (W), not total electricity consumption (kWh). To estimate how much electricity an appliance uses, use:

Electricity consumption (kWh) = Power (W) ÷ 1,000 × Usage time (hours)

For example, a 3,000 W kettle used for 10 minutes consumes:

3,000 ÷ 1,000 × 10 ÷ 60 = 0.5 kWh

Actual consumption can vary because some appliances, such as refrigerators, washing machines and ovens, do not continuously operate at their maximum rated power.

Average Electricity Consumption for an 80 m² House

An 80 m² property falls within the 51–100 m² floor-area category used in the UK government's Domestic NEED analysis.

The amount of electricity used within this category varies with the number of adults in the household. In the latest detailed floor-area analysis available, median annual electricity consumption for 51–100 m² properties ranged from roughly 1,850 kWh for one adult to 3,450 kWh for five or more adults.

For a household with two or three adults, this corresponds to roughly 2,550–2,900 kWh per year, or approximately 7–8 kWh per day.

This is substantially lower than the 11,000–15,000 kWh annual figure in the original version of this article. Those higher figures should not be presented as typical electricity consumption for an 80 m² UK home.

Average Electricity Consumption for a 100 m² House

A 100 m² property sits at the upper end of the 51–100 m² category in the NEED data. Its electricity consumption is influenced not only by floor area but also by household size and how the property is heated.

For households with two to three adults, annual electricity consumption in this size band was around 2,550–2,900 kWh, based on the government’s detailed consumption data. That is approximately 7–8 kWh per day.

A larger household, or a property with electric heating, an electric hot-water system, an EV charger or other high-demand equipment, can use considerably more.

It is therefore better to treat floor area as a starting point rather than a fixed predictor of electricity consumption. Government data shows that electricity use rises with both property size and adult occupancy, but the relationship is not proportional.

Average Electricity Consumption for a 150 m² House

A 150 m² property falls within the 101–150 m² category.

For this floor-area band, median annual electricity consumption in the detailed NEED data ranged from approximately 2,200 kWh for one adult to 4,200 kWh for five or more adults. For households with two to three adults, the corresponding figures were around 2,950–3,350 kWh per year.

That equals approximately 8–9 kWh per day for a two- to three-adult household.

A 150 m² home can, however, consume much more electricity if it relies on electric heating, electric hot water, air conditioning, an EV charger or several other high-power appliances.

How Many kWh per Day Is Normal for a UK House?

There is no single daily electricity figure that applies to every UK home.

As a broad reference, around 7–10 kWh per day is reasonable for many households using electricity mainly for lighting, appliances, electronics and cooking. Smaller households may use less, while larger households and homes with significant electrical heating can use considerably more.

For example, annual consumption of:

2,500 kWh = 6.8 kWh/day

3,000 kWh = 8.2 kWh/day

4,000 kWh = 11.0 kWh/day

Looking at daily usage can make your electricity consumption easier to understand, but seasonal variation is important. A household may use significantly more electricity during periods of increased heating, cooking or appliance use.

What Factors Affect Household Electricity Consumption?

The size of your home is only one factor affecting electricity consumption. UK government data shows that electricity use generally increases with floor area and adult occupancy, while heating systems, energy efficiency and household habits also play an important role.

Heating and Hot Water

Heating and hot water can significantly affect electricity use, particularly in homes with electric heating or immersion heaters. Homes using gas for heating generally have more of their heating energy demand reflected in their gas consumption instead.

Property Size and Insulation

Larger homes generally use more energy, but insulation, windows and overall energy efficiency can change how much energy is required to heat a property. Government data confirms that more energy-efficient homes tend to have lower median energy consumption.

Household Size and Daily Habits

More occupants usually mean greater demand from cooking, laundry, lighting and household devices. Working from home and frequent use of appliances can also increase electricity consumption.

High-Power Electrical Loads

Electric showers, heaters, tumble dryers, EV chargers and other high-power appliances can substantially increase electricity use, particularly when operated frequently.

How to Reduce Your Home Electricity Bill

Once you understand what drives your electricity consumption, you can focus on the areas with the greatest potential for savings.

Improve Insulation

Insulating walls, lofts and other areas where heat is lost can reduce heating demand and improve overall energy efficiency.

Choose Energy-Efficient Appliances

When replacing appliances, compare their energy ratings and expected electricity consumption rather than looking only at maximum power.

Adjust Everyday Usage

Use appliances efficiently, avoid unnecessary standby use and choose lower-energy settings where practical. For example, Ofgem recommends using washing machines at 30°C and running full loads where appropriate.

Monitor Your Electricity Consumption

A smart meter can help you track electricity use and identify periods or appliances that contribute most to your consumption.

Consider Solar and Battery Storage

Solar panels can generate electricity for household use, while battery storage can retain excess generation for later use. Whether battery storage is worthwhile depends on your electricity demand, solar generation, tariff and usage pattern.

For households looking to make better use of solar generation or prepare for power outages, battery storage can store excess electricity for later use. The AFERIY P300 Portable Power Station provides 3,000W of AC output and 2,048Wh of battery capacity, expandable to 10,240Wh, while the AFERIY P310 Portable Power Station offers 3,600W of output and 3,840Wh of capacity, expandable to 11,520Wh. These higher-output systems can provide backup power for a wider range of household appliances when mains electricity is unavailable.
