Energy Efficiency: How to sell your home faster with a few small changes
In today’s property market, energy efficiency is no longer just a buzzword—it’s a key factor that can significantly impact the speed and price at which your home sells.

With buyers increasingly prioritising homes that are both cost-effective and environmentally friendly, making small energy-efficient upgrades could be the edge you need to stand out in a competitive market.
Why energy efficiency matters
Energy Performance Certificates (EPCs) play a pivotal role in how buyers evaluate properties. Homes with higher EPC ratings (A or B) tend to sell faster and at a premium, while those with lower ratings (F or G) often struggle to attract interest and may sell for up to 7.4% less. Buyers are drawn to energy-efficient homes not just for their environmental benefits but also for the tangible savings on energy bills. For example, new-builds with high EPC ratings can save homeowners up to 56% annually on heating, lighting, and hot water costs.
Moreover, as the UK moves closer to its net-zero emissions target, future regulations are likely to make energy efficiency even more critical. Buyers increasingly view green credentials as an investment in long-term sustainability.
Simple changes that make a big difference
Improving your home’s energy efficiency doesn’t have to involve major renovations. Here are some simple and cost-effective upgrades that can boost your EPC rating and make your property more appealing:
- Insulation: Adding loft or cavity wall insulation is one of the most effective ways to improve energy efficiency. It reduces heat loss and lowers heating costs, making your home more comfortable year-round.
- Double or Triple Glazing: Upgrading windows not only improves thermal performance but also reduces noise pollution—an attractive feature for buyers seeking peace and quiet.
- LED Lighting: Replacing traditional bulbs with energy-efficient LED lights is an easy win that reduces electricity consumption while lasting longer.
- Smart Thermostats: Installing smart heating controls allows buyers to manage energy usage more efficiently, adding a modern touch to your property.
- Renewable Energy Options: Solar panels or heat pumps may require upfront investment but can significantly increase your home’s appeal and resale value.
Highlighting energy efficiency in your listing
Once you’ve made these updates, it’s essential to showcase them effectively in your property listing. Mention any improvements that enhance your EPC rating, such as insulation upgrades or renewable energy installations. Highlighting features like smart thermostats or solar panels can attract eco-conscious buyers who are willing to pay a premium for sustainable homes.
Rightmove’s data shows that properties with higher EPC ratings sell faster—homes rated B typically sell within 30 days compared to 37 days for those rated G. Including these details in your marketing materials could be the difference between a quick sale and months on the market.
The bottom line
Energy efficiency isn’t just good for the planet—it’s good for your wallet too. By making small upgrades, you can reduce your home’s environmental impact while increasing its marketability and value. Whether it’s adding insulation or installing smart technology, these changes could help you sell your home faster and attract buyers willing to pay more for a greener lifestyle.
