Smaller doesn’t always mean cheaper when it comes to your house. It’s sometimes more affordable to light and heat a smaller home, but keeping the bills under control still needs a well-managed budget.

After mortgage or rent, utility bills, e.g., gas and electricity, are usually your next biggest outgoing, so they should be the top priority when you’re planning a budget. 

Costs will depend on your usage habits and how many people you live with A two-bedroom home could have three or more people living there, and obviously that comes with a range of energy-use habits too! Your tariff, energy-efficiency of your appliances and a ton of other factors will also affect your monthly bills. 

Everyone pays for electricity, but the amount you pay can vary depending on your usage and other factors.  The cost of electricity depends on your tariff, supplier, usage, and the energy efficiency of your home. 

For example, the average annual electricity bill for a two-bedroom flat (1-2 people) is £670.21 (on a direct debit) – around £56 per month. This is an average based on Ofgem data, which shows that a typical low-consumption household uses 1,800 kWh of electricity per year. For a two-bedroom house, this will be higher, as a larger space uses more energy. 

Also, some flats only use electricity, meaning water and heat is generated this way– this can be more expensive than with a traditional gas boiler.

Averages are just that: average. Keep reading for a better idea of how much you’ll pay for electricity and ways to keep costs down.

Understanding your electricity bill

The first step to budgeting is taking the time to understand your bills.

Your electricity bill is made up of two elements:

1. Price per kWh (kilowatt hour): How much you pay per unit of electricity
2. Standing charges: A fixed daily fee to cover admin, grid maintenance, customer service, etc.

The Energy Price Cap

This is a limit on utility bills, specifically the price of energy, to make sure it’s fairly priced.

Essentially, the Energy Price Cap limits the price per unit and standing charges on a standard variable tariff. It changes every three months in line with the average energy prices. Visit Ofgem’s Energy Price Cap page to get the latest costs. 

The price cap applies to your bills if you pay for your electricity by:

• Standard credit (payment made when you get your electricity and gas bill).
• Direct debit.
• Prepayment meter.
• Economy 7 (E7) meter

It does not limit your total bill, just the price pay per unit of energy. If the amount you use isn’t covered by your monthly payment, you’re usually billed more at the end of your contract. 

Is the electricity bill for your two-bedroom house higher than average? Here are some potential reasons why:

• Higher energy usage: Since the price cap limits the maximum price per unit of gas and electricity (based on averages) and daily standing charges, not your total bill, it can still exceed the cap if you use more than average. 
• Property type: A two-bedroom flat with two adults will typically use less electricity than a family of three living in a two-bedroom house, for example.  
• Tariff types: The price cap applies only to standard variable tariffs and prepayment meters, so if you are on a fixed-rate deal, you are not capped by Ofgem. 
• Other costs: In addition to the standing charge and energy usage, you may incur charges for government taxes, levies, and supplier fees. 

Ofgem splits the average electricity bill into three categories:

• low usage (a one-bed flat or small house with 1–2 people)
• medium usage (your standard three-bed home)
• high usage (bigger homes or houses with more energy demand).

So, the typical usage for a two-bedroom house falls between low and medium.

For the purpose of this article, we’ll go with the low usage figures.

Average electricity usage for a one-to-two-bedroom property (1-2 people):

• Annual: 1,800 kWh
• Monthly: ~150 kWh
• Daily: ~4.9 kWh

How much is that in reality?

Here are some examples of appliances and their usage:

• A microwave uses around 0.8 kWh per hour, or roughly 0.13 kWh for a 10-minute reheat.
• A dishwasher typically uses 1.2–1.5 kWh per full cycle.
• An oven set to 200°C uses about 2–2.5 kWh per hour, depending on the model.

Your lifestyle will determine how well you match the ‘average’ figures, which are really only a guideline. 

Keep an eye on your daily habits, as small changes will make a big difference in keeping your bills and energy use down, for example:

• Whether you use a tumble dryer, electric airer, or crank up the heating to dry clothes
• Baths vs. quick showers: more hot water, higher energy use.
• Working from home with the heating on compared to being out all day with everything switched off.
• Having lots of gadgets, consoles, and smart devices constantly plugged in.
• A big household using multiple rooms (and heating them) throughout the day.
• Using older appliances instead of newer, energy-efficient models.

Is your bill higher than average? There are so many reasons why this might be the case. 

Remember, the Energy Price Cap only caps the price you pay per unit of energy, and for standing charges, not your monthly bill. Your bill is still based on how much you use (unless you have an Unlimited Energy package)

Here’s why your bill might be above average:

Tariffs

The price cap applies to standard variable tariffs and prepayment meters. If you’re on a fixed-rate tariff, you’re not covered by the cap, as it changes every quarter. 

Home size

A two-bedroom property could be anything from a small flat to a semi-detached house. The bigger your home, the more energy you will use, even if you are careful.

Your usage habits

With a traditional energy deal, the type you get from most suppliers, The more electricity you use, the higher your bill. If you work from home, for example, you’ll have more expensive bills than someone who is out of the house all day. Your monthly payment may not increase when your usage does, but if you use more than you pay for, you’ll get a bill at the end of your contract. 

Even if you’re home all day, you can still cut costs– take a look at our ways to keep energy usage down and reduce costs. 

Future price changes

The Price Cap is based on many economic and environmental factors, which is why it changes every three months. 

Don’t make big decisions based on predictions; wait for the price caps to be announced (usually a couple of weeks beforehand) to work out your budget.

Where you live

Electricity rates vary across the UK. Places like North Wales and the Mersey have higher-than-average electricity costs because of  transport costs, challenging terrain, and population density. Southern Scotland has the lowest average electricity bills.

How you pay

The way you pay impacts what you pay. Monthly direct debit is the cheapest way to pay your electricity bill because it’s the most efficient for the provider, and they pass on the benefit to you. 

More expensive ways to pay include via pre-payment meter or upon receipt of your bill. 

Additional costs

On top of your usage and standing charge, you might still pay a little extra because of things like taxes, levies, or supplier fees.

A bill for a standard energy deal breaks down exactly how much electricity you’ve used in kWh, along with your standing charges. Usually your monthly payment is what your supplier thinks you’ll use during your contract, divided by the number of months in your contract.

E.g. If your supplier thought you’d use £1200 of energy during a 12-month contract, you’d pay £100 a month. 

If you’ve got a smart meter, you can also check your real-time usage. This is handy for spotting energy drains like appliances left on standby.

If your supplier has an app, you can usually check your usage and credit there too. 

Bills can be calculated monthly, quarterly, or even annually, depending on your supplier, even if you pay every month. That means your own maths might not match your monthly payments perfectly, especially when averaged over the year.

How to calculate your electricity bill:

1. Grab your latest bill from your supplier’s online account, or check your smart meter for up-to-date kWh usage.
   
   
2. Check your rates. If your last bill covered a previous quarter, remember your unit rate or standing charges might have changed.
   
   
3. Do the maths:
   (Total kWh used × Unit rate in £) + (Number of days × Standing charge in £) = Your bill.

Two-bedroom homes vary. You can’t compare the electricity usage of a couple living in a small flat with a family with young children in a two-bed semi. 

So, the average usage for a two-bed home is likely to fall somewhere between Ofgem’s "Low" (1,800 kWh) and "Medium" (2,700 kWh) usage, depending on occupants.

Here are the average electricity bills for low, medium and high usage properties:

Gas and electricity vs just electricity?

Most two-bedroom homes will have gas and electricity, with gas heating and water. Some flats might only have electricity, which is typically more expensive, but costs can be kept down with smart usage. 

Reducing your usage is the single most effective way to cut down electricity bills. Check out our easy energy saving guide and energy saving myths for more info. 

Here are some easy ways to bring your bills down whether you’re a tenant or a homeowner:

• Get a smart meter: It shows your real-time energy use, helping you spot what’s using the most power.
• Use smart plugs: These let you check how much energy certain appliances use and switch them off remotely or set timers.
• Switch to LED bulbs: They use around 80% less electricity and last far longer than old halogen bulbs, so they save both energy and money over time.
• Turn off appliances at night: While “vampire energy” is often overstated, lots of tech on standby can still add up. Switch them off fully when you can.

If you’re a homeowner looking to invest in energy efficiency initiatives to make your home more sustainable, here are some bigger steps to take:

• Insulate your home: A well-insulated house stays warmer for longer, meaning you won’t rely as much on electric radiators, heated blankets, or other plug-in heaters. Older homes are especially likely to benefit from improved insulation.
• Install a heat pump: Heat pumps run on electricity but use it far more efficiently than traditional gas or electric heating. For every unit of electricity they use, they can generate three to four units of heat in return.
• Add solar panels: With enough sunlight, you can generate your own electricity and sometimes even feed surplus energy back into the grid.

Making a budget? “Average” isn’t enough

Averages are a useful starting point, but they can’t predict exactly what you’ll pay.

For 2-bed properties especially, costs can vary a lot depending on whether you’re in a flat or a house, and how many people are living there. More rooms, more occupants, and more appliances all change the final number.

If you want a simpler way to budget, One Utility Bill bundles all your essential bills, including electricity, into one fixed monthly payment. No surprises, just one clear cost that makes managing your money easier.
