There are several factors that can influence your gas and electricity bills. The main factor is the tariff you are on with your energy supplier, tariffs can vary greatly between suppliers and your supplier may even have a variety of different priced tariffs you could be on.

Another important factor to consider is your energy usage. The more energy you use, the higher your bills will be. This may sound obvious, but being on a fixed tariff doesn’t mean a fixed energy bill and the price cap is a maximum unit charge, not a cap on the total amount you can pay.

Additionally, standing charges, which are daily fees, can also contribute to your overall energy costs. The less energy you use, the higher proportion of your bill these standing charges will make up.

Lastly, investing in smart meters and energy-efficient appliances can help lower your energy bills in the long run. A more energy-efficient washing machine may be slightly more expensive, but it could save you money on your bills in the long run.

The average gas and electricity bills for a one-bedroom flat in the UK can vary depending on factors discussed above, like energy usage, tariff and location.

Typically, however, bills range from £70 to £110 per month for the average one-bedroom flat for gas and electricity combined. Standing charges are likely to make up about £22 of this.

If you are paying more then don’t forget that energy costs are also influenced by the size of the flat, insulation, and the number and type of appliances used etc. It’s also worth noting that your bills may be higher during colder months, particularly for gas, due to increased heating usage.

You can work out what your actual energy daily, monthly or yearly energy bill would be using our energy bill calculator. You will need to know the daily standing charge and unit cost for electricity and gas (if applicable), and then you can see the actual rate you would pay for various usage.

On average, a one-bedroom flat in the UK uses around 2,000 kWh of electricity per year.

To give you a rough idea of what that means, one kWh is about the amount of energy it takes to boil 10 kettles, run a full cycle of your washing machine, or keep your laptop powered for two days.

The actual amount you use will vary depending on several factors but mostly due to the number of occupants and number of appliances used.

On average, the electricity bill for a 1-bed flat in the UK ranges from £40 to £60 per month.

This is £480 to £720 per year.

This average amount also mainly covers flats that use a mix of gas and electricity for heating. If your flat uses electricity only, your bill is likely to be higher.

According to Ofgem, a one-bedroom flat in the UK uses approximately 8,000 to 17,000 kWh of gas per year.

The exact amount of gas consumption depends on factors such as the heating system, insulation of the flat and whether gas is used for cooking.

The cost of gas bills can vary depending on factors like heating system efficiency, how much gas is used for cooking, and the amount of hot water needed.

On average, a 1-bed flat in the UK can expect to pay around £30 to £50 a month on gas.

Or an annual gas bill ranging from £400 to £600.

However, it’s important to note that these monthly figures can fluctuate depending on the time of year, with higher gas consumption during autumn and winter months.

By combining households, you can share expenses like heating and electricity, making it more affordable. You will likely use more energy with an extra person in your flat, but it is unlikely to come anywhere near doubling your costs. If you can split these bills 50/50, then living with a partner is likely to save you money on an individual basis.

If you think your gas and electricity bills and usage are too high, then reducing energy consumption in a one-bedroom flat is a crucial step towards lowering them. Here are a few quick ways to help lower your consumption:

  • Unplug unused electronic devices, as they still consume energy even when turned off.
  • Capitalise on natural light and adjust your thermostat to maintain optimal temperature without excessive energy usage.
  • Regularly maintaining appliances like boilers can improve their efficiency and reduce energy waste.
  • Installation of proper insulation and sealing drafts can prevent energy loss, meaning less energy is needed to keep your flat warm.
  • Use energy-efficient appliances and LED bulbs where possible.
  • Moreover, fitting smart meters in the flat allows you to monitor your energy consumption in real time, enabling you to make informed decisions about your usage.

When it comes to energy tariffs for one-bedroom flats in the UK, there are various options available from different suppliers. One popular choice is fixed-rate tariffs, which provide stability in energy costs over a set period. On the other hand, variable-rate tariffs fluctuate based on market conditions, like the Tracker tariff from Octopus. Another option to consider is time-of-use tariffs, which offer different rates depending on the time of day.

To find the best energy tariff for your one-bedroom flat, you can use comparison websites that provide information on different plans and pricing. By comparing energy tariffs, you can ensure that you are getting the most cost-effective option for your energy needs.

The average gas and electricity bill for a one-bedroom flat in the UK can vary based on several factors such as the size of the flat, energy consumption habits, and energy efficiency measures taken. On average, a one-bedroom flat in the UK consumes 170 kWh of electricity and 650 kWh of gas each month, resulting in an average combined bill of £70-£110. However, it’s important to note that individual circumstances may differ.

Hi, I'm Rob and I run Energy-Review.co.uk. I initially started this project 5 years ago when I was looking to switch energy suppliers and found there wasn't a website that provided simple, data backed reviews on all the suppliers available. Since then, I spent have a lot of time (too much some may say!) looking at all publicly available data about each supplier and writing reviews using this information. These reviews are updated as regularly as possible and any data is backed up by a source where necessary. I have also started writing guides on various energy related topics which hopefully you will find useful. If you find any issues, please use our contact form to let us know.
