Compare Your Electricity Usage: Is 7.5 kWh Per Day Typical for UK Homes?

Understanding Your Household's Electricity Usage

Knowing how your electricity consumption compares to UK averages can help you choose the right tariff and avoid overpaying. According to Ofgem's Typical Domestic Consumption Values (TDCVs), the typical household electricity usage for a medium-sized home is 2,700 kWh per year, which works out to about 225 kWh per month or 7.5 kWh per day.^{[1][2][3][4][5][7]}

Your actual consumption depends on several factors: home size, number of occupants, heating type, and daily habits. A 1-2 person household in a flat typically uses around 5 kWh per day, while larger families in 4-5 bedroom homes can reach 11 kWh daily.^{[1][2][3][4][5][7]}

Daily Electricity Usage by Household Size

Here's how different household types compare for daily electricity consumption:

• Low usage (1-2 people, flat or 1-bedroom): Around 5 kWh per day (1,800 kWh annually)^[1][3][5]
• Medium usage (2-3 people, 2-3 bedroom house): About 7.5 kWh per day (2,700 kWh annually)^{[1][2][3][4][5][7]}
• High usage (4-5 people, 5+ bedroom house): Roughly 11 kWh per day (4,100 kWh annually)^{[1][2][3][4][5][7]}

A typical 3-bedroom house specifically uses around 2,700-3,300 kWh per year, or 8-9 kWh per day, with higher consumption if you have electric heating or work from home offices.^[1][2]

Which is More Expensive: Gas or Electricity in the UK?

Electricity is significantly more expensive than gas per unit of energy. Under the January 2026 Ofgem price cap, electricity costs 27.69p per kWh (plus a 54.75p daily standing charge), while gas costs just 5.93p per kWh (plus 35.09p daily standing charge).^[5]

For a medium household, this translates to annual costs of approximately £948 for electricity and £810 for gas.^[5] Combined dual-fuel bills average £1,758 per year under the Q1 2026 price cap.^[8] This price difference explains why homes with gas central heating typically have lower energy bills than those relying entirely on electricity.

When Off-Peak Electricity Tariffs Make Financial Sense

Off-peak electricity tariffs like Economy 7 or Economy 10 offer cheaper rates during overnight hours (typically 10pm-8am) but charge higher daytime rates. These tariffs work best for households that can shift significant electricity usage to off-peak periods.^[7]

You'll likely benefit from off-peak tariffs if you:

• Use electric storage heaters
• Charge an electric vehicle overnight
• Run dishwashers, washing machines, or tumble dryers during off-peak hours
• Use more than 40% of your electricity during off-peak periods^[2][7]

However, if you have gas heating and use electricity fairly evenly throughout the day, off-peak tariffs often cost more overall due to higher daytime rates. Most suppliers offer online calculators to help you work out whether switching would save money based on your usage patterns.

Understanding Dual Fuel and Fixed Price Deals

Dual fuel tariffs, where you get both gas and electricity from the same supplier, often provide modest discounts compared to having separate suppliers. For medium usage households, dual fuel deals typically cost £1,710-£1,894 per year on direct debit payment methods.^[4]

Fixed price deals lock in your unit rates and standing charges for 12-24 months, protecting you from price cap increases. They work particularly well if your usage is stable and predictable. Variable deals follow the Ofgem price cap, which can change quarterly but offers more flexibility.^[3][5][8]

To decide between fixed and variable tariffs, calculate the annual cost using your actual kWh consumption rather than average figures. Fixed deals typically make more sense for high-usage households or when energy prices are expected to rise.

Green Energy Options and Competitive Pricing

Green energy tariffs source 100% renewable electricity from wind and solar power. Many suppliers now offer green tariffs at similar prices to standard deals, often aligning closely with the price cap rates.^[5] These tariffs can be particularly attractive when combined with dual fuel options for both environmental and financial benefits.

Major suppliers like OVO offer competitive green tariffs that work well for typical household electricity usage patterns. While specific 2026 pricing varies by supplier, most green electricity tariffs for medium usage align with the current price cap of around £948 per year for electricity only.^[1]

Calculating Your Best Tariff Option

To find your optimal energy deal, start by checking your actual consumption from recent bills or your smart meter readings. Compare this against the typical figures: if you're using significantly more or less than 7.5 kWh per day for electricity, or 31.5 kWh per day for gas (11,500 kWh annually), standard tariffs might not be your best option.^[2][4][7]

For most households, the decision comes down to fixed versus variable pricing. Services like Lodo can help automate the comparison process, finding deals that match your specific usage patterns rather than generic averages.

Remember that switching is usually straightforward - your new supplier handles most of the paperwork, and you won't experience any interruption to your energy supply during the switch.

What is Broadband Internet in Relation to Energy Costs?

While broadband internet refers to high-speed internet access via fibre, cable, or DSL connections, it has minimal impact on your household electricity consumption. A typical broadband router uses around 0.05-0.1 kWh per day - negligible compared to your overall daily usage.^[5] Some utility companies offer bundled packages that include broadband alongside gas and electricity, but these are separate services with different pricing structures.
