One of the many perks of buying a new build is that they are extremely energy-efficient homes; so much so that the Home Builders Federation have found that new build homeowners save up to £420* per year on their energy bills compared to own-ers of older second-hand homes.
Our new homes are jam-packed with energy efficient features to help you save mon-ey on your bills, ranging from zoned heating and high-spec windows to brand new boilers, as well as energy-efficient lightbulbs and well-insulated lofts. Plus, many of our homes are air-pressure tested to ensure they are air-tight, keeping them cosy and warm.
Generally, our high-quality energy-efficient new build homes use far less energy than older houses. HBF research from 2026 shows that 85%* of new build homes had an A or B Energy Performance Certificate rating, while less than 5%* of older homes reached the same standard.
Unfortunately, human activities have raised the atmosphere's carbon dioxide content by 50%*** in less than 200 years, so it’s time to do our bit!
Old homes in the United Kingdom are some of the worst insulated in Europe**, but here’s the good news: the average new build emits an annual 1,080kg* less carbon than older houses, meaning that by buying new, you’re also protecting the planet.
One of our goals has always been that our standard house types reduce waste generation from components such as plasterboards. This has helped us to ensure that 98% of construction waste is recycled and diverted away from landfill. We also source eco-friendly materials and employ local labour, all adding to our sustainability credentials.
Thanks to our energy-efficient homes being so well insulated, you’ll notice that they are by design significantly warmer than your average older house!
Plus, our high-quality windows suck the sunlight in, keeping your home bright, airy and warm.
This means you’re less likely to need your heating on as often in an Avant home, as you chose to buy new.
We always fit energy efficient appliances in our homes and work with suppliers who put sustainability at the forefront of their product development.
From washing machines to fridges, cleaning to cooking, our white goods incorporate the latest energy saving technology.
Other initiatives in our new homes may include:
• Photovoltaic (PV) panels
• Low energy light bulbs
• Electric vehicle (EV) chargers
• Achieving an average SAP rating of 83B
• Conducting air pressure testing
• Boilers with an A energy rating

It’s not only electricity you’ll save on! With a new Avant home, your water bill is likely to be reduced considerably.
All our high-quality energy-efficient new build homes have undergone water efficiency calculations, achieving 94 – 99 litres per person per day (LPPPD), below the industry required minimum.
This has been achieved by implementing initiatives such as low-flush and dual flush toilets, low flow taps and showers, as well as wastewater heat recovery, ensuring the water consumption of the home is lower than a second-hand home.
Therefore, if you want to save money on bills, then there’s never been a better time to buy new!
With an Avant home, you’ll have peace of mind that your monthly bills will most definitely be lower than they would be in an older home.
