Energy efficient new build homes can save on average over £2,600 in energy bills

Wednesday, 19th October 2022

Saving on your energy bills has become a hot topic in recent months. You simply can’t escape the news on the radio, television or even on social media. It’s everywhere. But there is hope for those wishing to buy a new build home. A new report published by the Home Builders Federation (HBF) has found that buyers of new build properties will save on average £2,600 in energy bills and reduce carbon emissions by more than 2 tonnes per property each year. As a collective, the report states, new build home buyers are saving over £500 million and reducing carbon emissions by over 500,000 tonnes a year.

What is energy efficiency?


So, what is energy efficiency? Energy efficiency simply means using less energy to perform the same task – that is, eliminating energy waste. Not only does an energy efficient home reduce greenhouse gas emissions and demand for energy imports, it also lowers your yearly household cost. 

According to HBF’s report, new build properties significantly reduce energy usage, with the average new build using approx. 100 kWh per m2 each year, as compared to older properties which require an average of 259kWh per m2.

The report further states new build properties save on average £2,000 per property each year, with the average running costs for a new build totalling £1,500 compared to older properties that average £3,570. Interestingly, these savings rise further to £2,600 a year when looking at new build houses alone, rather than smaller properties such as flats or bungalows. 

What is an EPC? 


You may hear the acronym EPC used a lot, whether you’re selling, buying or renting, it’s hard to miss. It’s probably the deciding factor now more than ever when purchasing a house in today’s climate. So, what actually is EPC and what does it measure? 

An EPC is a home energy survey that reveals how energy efficient a home is. The survey includes a list of recommendations on how to improve your home’s energy efficiency and is a legal requirement if you’re selling, leasing or renting a property. 

Ranging from A (very efficient) to G (inefficient), an EPC survey tells you a lot about a property, especially an indication of how much the property will cost on energy bills.

In the HBF report, 84% of new build homes were rated with an EPC of B or above while less than 4% of existing dwellings reached the same standard. Castle Green homes prides itself on building high quality homes with EPC ratings of A and B standard. Across all our developments, homes are sustainable by design, optimising thermal efficiency through the building fabric rather than add-on measures.


How can a good EPC rating benefit me?


  • Lower energy bills – due to build quality and materials used, new build homes lower your consumption and can save on average £2,600 per year on energy bills
  • Improve property value – selling a property with a good EPC rating will be extremely desirable for house hunters and likely improve the value of your home
  • Lower Mortgage – there’s a chance you can receive lower mortgage rates through green mortgages
  • Lower your carbon footprint – buying a new build with high energy efficiency will lower your carbon emissions

Energy efficiency and the environmental impact


Saving money on rising energy bills is top priority for many homeowners. But saving money on energy bills, coupled with improving the environmental impact for our planet is an even more desirable prospect.

The HBF report outlines buyers of new build homes are contributing to the country’s progression towards net zero, with each new build preventing 2.2 tonnes of carbon being emitted each year. 

At Castle Green Homes, we are always looking at ways to improve our green credentials. That’s why we are carbon neutral and have achieved net-zero status, with further plans to reduce our emissions by at least 50% by 2030. By constantly improving the way we build energy efficient homes, Castle Green’s customers will move into a home that will not only lower their energy bills, but significantly reduce the amount of carbon emitted each year.
