Are new homes more energy efficient?

When buying a new home, there are plenty of questions people ask:  

“What is the local area like?” 

“Are there good schools nearby?” 

“What’s included in the sale?” 

But one question we are hearing more and more, as buyers deal with ever-increasing energy bills, is: “Are new homes more energy efficient?” 

And the quick and simple answer is yes, they are. Here are 8 reasons new homes come out on top for energy efficiency, and for saving you money!

1. Modern building methods

Building techniques have come a long way. Today’s new homes incorporate energy-saving methods in all aspects of their design and build, using materials such as double or even triple-glazed windows, high performance thermal insulation and modern pipework and electrical cabling. The result? A home that’s designed to keep you warm without relying so much on heating systems.

2. Better insulation

New homes use modern materials and insulation technology in the walls, floors and roof that help keep the warmth in and the cold out. Not only does this keep you more comfortable, but it also means your heating system doesn’t have to work overtime - saving energy and cutting down on costs.

3. Double or triple-glazed windows and doors

If you’ve ever felt a chill coming from old single-pane windows, you’ll appreciate the benefits of double or even triple glazing. Not only do they help keep your home cosy, but they also reduce noise and condensation. 

4. Solar panels

One of the biggest advancements in new home energy efficiency is the use of solar panels. Many new builds now come with solar panel systems already installed, allowing you to generate your own clean energy for hot water, heating, EV charging and other electrical items. Solar panels can reduce your need for electricity from the grid, potentially cutting costs by up to £200 a month. 

5. Air source heat pumps

Getting heat from thin air? That’s precisely what an air source heat pump does. It pulls warmth from the outside air (even in chilly UK winters) and uses it to heat your home and water. While it might sound like magic, it’s actually a super-smart, eco-friendly technology that is growing in popularity every year.

While heat pumps can be challenging and costly to retrofit to existing houses, they are often fitted as standard in new build homes. Want more good news? Air source heat pumps can save you on average between £100-£200 per year on energy bills and add up to 7% to the value of your home. 

6. Integrated, efficient appliances

New homes often feature integrated appliances that are both sleek and energy-efficient. From dishwashers to ovens, these appliances use less power while doing exactly the same job. Plus, they’re built-in, which means you’ll have a stylish and tidy kitchen without the clutter!

We also fit LED lighting in our homes as standard, which can be up to 90% more efficient and last up to 25 times longer than incandescent bulbs. 

7. Energy-efficient boilers

Modern new builds often feature ultra-efficient boilers designed to use minimal energy to deliver maximum warmth. Working in tandem with smart technology (smart thermostats), they can adjust to your household’s specific needs, providing consistent heat as and when you need it. This means fewer emissions, lower bills and no more waiting around for the hot water tank to fill up!

8. Air pressure tested

New homes go through rigorous air pressure testing to make sure they’re well-sealed and insulated. This testing identifies any potential leaks where air might escape through gas or cracks, so developers can fix them and meet the air permeability rating specified. With a tightly sealed home, the warm air stays where it is supposed to, reducing the need for constant heating and making your home more energy-efficient all year round.

How much more energy efficient are new build houses?

So now you know what building materials and technology you can expect to find in a new build home, what does that actually equate to in terms of energy usage and potential savings? Based on research by the Home Builders Federation, the average new build house emits 67% less carbon than a comparable older property. That equates to an average saving of £81.50 a month, and a whopping £979 a year.
