Improving your home’s energy efficiency can help lower your energy bills, reduce your carbon footprint, and make your living space more comfortable. Whether you want to upgrade insulation, switch to energy-efficient appliances, or adopt small daily habits, there are plenty of ways to make your home more eco-friendly.
This guide covers practical steps to boost energy efficiency, including cost-effective solutions and long-term investments to reduce your energy consumption.
Why Energy Efficiency Matters
An energy-efficient home brings multiple benefits, including:
Lower energy bills – Using less electricity and gas reduces your household costs.
Increased property value – Energy-efficient homes are more attractive to buyers.
Improved comfort – Proper insulation and heating make your home warmer in winter and cooler in summer.
Environmental benefits – Reduced energy use lowers carbon emissions, helping the planet.
1. Improve Home Insulation
Check and Upgrade Loft Insulation
A significant amount of heat escapes through the roof. Loft insulation should be at least 270mm thick to retain heat effectively.
Use fibreglass, mineral wool, or eco-friendly alternatives like sheep’s wool.
Check for gaps and top up insulation if needed.
Install insulation boards if you have a flat roof.
Upgrade Wall Insulation
Around 35% of heat loss occurs through walls. The best insulation depends on your home type:
Cavity wall insulation – Suitable for most homes built after 1920.
Solid wall insulation – External or internal insulation works for older homes.
Draught-proofing walls and skirting boards – Sealing gaps reduces heat loss.
Insulate Floors and Windows
Use underfloor insulation if you have a suspended timber floor.
Upgrade to double or triple glazing to reduce heat loss through windows.
Use thermal curtains or blinds to trap heat indoors.
2. Upgrade to Energy-Efficient Heating Systems
Install a Smart Thermostat
Smart thermostats like Hive or Nest allow you to control heating remotely and learn your habits to save energy.
Switch to an Energy-Efficient Boiler
An A-rated condensing boiler is much more efficient than older models. If replacing your boiler isn’t an option, servicing it regularly helps maintain efficiency.
Consider Heat Pumps
Air source heat pumps extract warmth from the air.
Ground source heat pumps use underground heat to warm your home.
Both options provide long-term savings and work well with underfloor heating.
3. Reduce Electricity Usage with Energy-Efficient Appliances
Upgrade to LED Lighting
Switching to LED bulbs can reduce electricity use by up to 80% compared to traditional bulbs. They also last much longer, cutting replacement costs.
Use Energy-Efficient Kitchen Appliances
Look for A+++ rated washing machines, fridges, and dishwashers.
Use an induction hob instead of gas for more efficient cooking.
Avoid standby mode—turn off appliances when not in use.
4. Generate Your Own Renewable Energy
Install Solar Panels
Solar panels can cut electricity bills and earn you money through the Smart Export Guarantee (SEG). The upfront cost is high, but they provide long-term savings.
Use a Solar Water Heating System
This system heats water using solar energy, reducing gas or electricity usage for hot water.
Consider Wind or Hydropower
If you live in a rural area, installing a small wind turbine or micro-hydro system can help generate power for your home.
5. Reduce Water Waste and Heating Costs
Install a Water-Saving Showerhead
A water-efficient showerhead can cut water use by 30-50% without reducing pressure.
Fix Leaky Taps
Dripping taps waste thousands of litres of water per year. Fix leaks quickly to reduce unnecessary usage.
Use a Smart Water Meter
These devices track water usage and help detect leaks or excessive consumption.
6. Improve Daily Energy Habits
Even small changes can lead to big savings over time:
Unplug devices when not in use to avoid phantom energy consumption.
Wash clothes at 30°C instead of higher temperatures.
Dry clothes naturally instead of using a tumble dryer.
Turn off lights when leaving a room.
FAQs About Making a Home More Energy Efficient
1. What is the cheapest way to make my home energy efficient?
Some of the most cost-effective methods include draught-proofing doors and windows, switching to LED bulbs, and using energy-saving habits like washing clothes at lower temperatures.
2. Do energy-efficient improvements increase home value?
Yes, homes with better Energy Performance Certificate (EPC) ratings are more attractive to buyers and can sell for higher prices.
3. Is it worth installing solar panels in the UK?
Solar panels provide long-term savings and can reduce reliance on the grid. With government incentives like the Smart Export Guarantee, you can also earn money from excess electricity generation.
4. How much can I save by switching to a smart thermostat?
Smart thermostats can reduce heating bills by up to £150 per year by optimising temperature settings based on your habits.
Final Thoughts
Making your home more energy efficient is one of the best ways to save money on energy bills, increase comfort, and reduce your environmental impact. Whether through simple upgrades like LED lighting and insulation or bigger investments such as solar panels or heat pumps, every change contributes to a more sustainable home.
If you’re considering home energy improvements, check if you qualify for UK government grants like the Energy Company Obligation (ECO) scheme to help with costs. Investing in energy efficiency today will provide long-term benefits for both your finances and the planet.
