Average Gas and Electricity Bill for a Three Bed House (2023)

If you’re a homeowner in the UK with a three-bedroom property, you’ve likely wondered about your energy bills and how they stack up against the national average.

Energy consumption can be a significant monthly expense, and it’s essential to know how much you should reasonably expect to pay. Firstly, lets look at what factors affect your bills:

What impacts your gas and electricity bills?

Several variables impact how much gas and electricity your household will use. These include:

  • Location: Gas and electricity rates can vary between different regions in the UK.
  • Number of Occupants: More people generally mean higher usage.
  • Home Efficiency: Older homes often lack modern insulation and efficient heating systems, leading to higher bills.
  • Appliance Usage: High-energy appliances like air conditioners, electric ovens, and washing machines contribute significantly to your energy bills.
  • Seasons: Expect higher bills during winter and sometimes summer, depending on cooling needs.

What is the typical gas and electricity bill for a three bedroom house?

The typical gas and electricity bill for a three-bedroom house can vary considerably based on a range of factors, such as those metnioned above. Based on national averages and various energy comparison sites however, the annual dual fuel (gas and electricity) bill for a three-bedroom house is generally around £1,800 to £2,500. This estimate takes into account both gas and electricity costs.

It’s important to note that these figures are just rough estimates and your bill can deviate significantly based on your particular circumstances.

For instance, if your home is newer and has good insulation and energy-efficient appliances, your costs could be at the lower end of that spectrum. Conversely, if you live in an older property with poor insulation, you might find yourself at the higher end. Seasonal variations also play a role; you’re likely to spend more on heating in the winter and potentially more on cooling during hot summer months.

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.
