Improving your home energy efficiency is not only an environmentally friendly choice but also a smart financial decision. By making your home more energy-efficient, you can reduce your carbon footprint and cut hundreds of pounds from your annual gas and electricity bills. In this guide, we’ll explore how to check your home’s energy efficiency, discuss various energy-saving upgrades, and highlight ways to use less energy daily. Whether you're looking for small changes or major energy efficiency improvements, there are plenty of options to consider.
How to Check If Your Home Is Energy Efficient
Before you dive into upgrades, it's essential to assess how energy efficient your home currently is. The Energy Saving Trust offers a Home Energy Check, a free 10-minute assessment designed to evaluate your home's energy efficiency. This check-up will identify areas where you can make improvements, such as upgrading insulation or installing energy efficient appliances. Once you have a clear understanding of where energy is being wasted, you can begin making the necessary changes.

They can provide tailored guidance, helping you choose the right upgrades and access any available funding or support for energy-saving measures.
Energy Efficiency Improvements: Key Upgrades
Improving your home’s energy efficiency often involves more than just simple tweaks. For long-term savings, consider making significant energy efficiency improvements that will pay off over time.
1. Insulation: Keep the Warmth In
One of the most effective ways to improve home energy efficiency is to ensure your home is well-insulated. Poor insulation can lead to significant heat loss, causing your heating system to work harder and increasing your energy bills. Cavity wall insulation is a great place to start, as it prevents heat from escaping through the walls. Loft insulation is equally important, as up to 25% of heat can be lost through the roof. For maximum effectiveness, the recommended depth for loft insulation is between 25-27 cm.
2. Boiler Upgrades: A Major Energy Saver
Old, inefficient boilers can account for up to 60% of your household energy usage. Upgrading to a modern A-rated high-efficiency condensing gas boiler can significantly reduce your bills—by as much as £570 annually. This upgrade also helps lower your carbon footprint, as newer boilers emit less carbon dioxide. For homeowners interested in energy-efficient heating systems, this is one of the most impactful changes you can make.
3. Ground Source Heat Pumps: Renewable Energy Option
Another major improvement you could make is installing ground source heat pumps. These systems use pipes buried in your garden to extract heat from the ground, which can then be used to heat your home. While the upfront costs can be high, ground source heat pumps are highly efficient and can reduce both your energy bills and your environmental impact over the long term.
4. Draught-Proofing: Stop Heat Loss
Older homes, especially those with single-pane windows, often suffer from draughts that allow cold air in and warm air out. By draught-proofing your windows and doors, you can prevent unnecessary heat loss and improve your energy efficiency rating. Homes with double or triple-glazed windows installed after 2002 are less likely to need draught-proofing, but older properties can benefit significantly from this cost-effective solution.
Simple Changes to Improve Home Energy Efficiency
While upgrades and installations can provide substantial benefits, there are also smaller changes you can make to improve home energy efficiency without breaking the bank.
1. Switch to Energy-Efficient Bulbs
Lighting accounts for a significant portion of your electricity usage. Energy-efficient appliances like LED light bulbs can help reduce this. These bulbs use up to 80% less energy than traditional incandescent bulbs and last much longer. While the initial cost of LED bulbs is higher, the savings you’ll see over time make them well worth the investment.
2. Turn Off Stand-By Mode
Many appliances, such as televisions and game consoles, continue to use energy even when they're not in use. Leaving them on stand-by mode can cost you around £30 a year. To avoid this, switch off appliances at the plug when they’re not needed. The only exceptions are items that need to remain powered for scheduled tasks, like washing machines or TV boxes.
3. Cut Energy Use in the Kitchen
The kitchen is one of the main areas where households can save energy. Simple changes, such as using a bowl to wash up instead of running water or boiling only the amount of water you need in the kettle, can make a big difference. Additionally, cutting one washing load per week can save enough energy to reduce your bills by about £30 per year.
4. Choose Energy-Efficient Appliances
When it's time to replace kitchen appliances, be sure to choose energy-efficient appliances with A, A+, or A++ energy ratings. These appliances, such as fridges, washing machines, and dishwashers, consume far less energy than older models, helping to reduce your overall energy consumption.
Monitor Your Energy Usage
Knowing how much energy your home consumes is key to improving your energy efficiency rating. Both smart meters and energy monitors provide valuable insights into your energy use, helping you identify areas where you can make improvements.
1. Smart Meters
A smart meter communicates directly with your energy supplier, sending real-time data about your usage. This means your bills are always accurate, as they are based on actual consumption rather than estimates. The UK Government is rolling out smart meters to every home, making it easier to track energy usage and potentially switch to a cheaper tariff.
2. Energy Monitors
While smart meters give you an overall picture of your energy usage, energy monitors provide more detailed information about individual appliances. Many energy monitors allow you to track energy use in real-time and see how much different appliances are costing you. These devices can help you identify which appliances are the most energy-hungry, allowing you to make smarter choices about how and when you use them.
Switch Your Energy Provider for Additional Savings
One of the easiest ways to save money on your energy bills is by switching energy providers. Many homeowners allow their energy contracts to roll over onto their supplier’s standard default tariff, which is often the most expensive option. By shopping around for a better deal, you could save up to £768 per year. There are plenty of comparison websites that make it easy to find the best deal for your home’s needs.
Additional Tips for Improving Home Energy Efficiency
In addition to the upgrades and smaller changes mentioned earlier, there are a few more tips that can help improve your home’s energy efficiency:
- Install Solar Panels: Solar panels generate electricity from the sun, offering a renewable energy source that can significantly reduce your energy bills over time.
- Use Smart Thermostats: A smart thermostat allows you to control your heating remotely, ensuring that your home is only heated when necessary. Some models can even learn your routine and adjust the heating accordingly.
- Upgrade to Energy-Efficient Windows: Replacing old windows with double or triple glazing can reduce heat loss during the colder months. Look for windows with a high energy efficiency rating, which will reflect heat back into your home.
- Seal Gaps Around Doors and Windows: Even the smallest gaps around doors and windows can let in cold air. Using weatherstripping or caulking to seal these gaps can make a significant difference in your home’s comfort and energy efficiency.
Final Thoughts
Improving home energy efficiency doesn’t have to be overwhelming or expensive. Whether you’re making major upgrades, like installing insulation or upgrading your boiler, or making smaller changes, like switching to energy efficient appliances, every step you take will bring benefits. Not only will you save money on your energy bills, but you’ll also reduce your home’s carbon footprint, contributing to a more sustainable future. Take action today to make your home more energy efficient and enjoy the long-term rewards.
