Avant's Energy Efficient Homes
Save up to £420* per year by buying one of Avant’s eco-friendly homes!
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 owners of older second-hand homes.
Our new homes are full of energy efficiency features to help you save money 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 airtight, 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.
Eco-friendly homes to protect your wallet and the planet
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.
Great features to keep your home cosy
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!
Our triple glazed windows† make the most of natural sunlight, helping to keep your home bright, airy and warm all year round.
This means you’re less likely to need your heating on as often in an Avant home, as you chose to buy new.

A bucket full of savings
Saving money doesn't stop with your energy bills. Thanks to a range of water-efficient features, an Avant home could help reduce your water usage and household costs too.
Our homes are designed to use less water than many older properties, achieving just 94–99 litres per person per day (LPPPD) – exceeding industry standards for water efficiency. Features such as dual-flush toilets, low-flow taps and showers, and wastewater heat recovery technology all work together to minimise water consumption without compromising on comfort.
So, when you choose an Avant home, you can enjoy a more sustainable lifestyle while benefiting from lower running costs.
Therefore, if you want to save money on bills, 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.
