New build homes to save you over £3,100 on energy bills

Monday, 20th February 2023

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.

However, there is a glimmer of hope for those looking to purchase a new build home.

A recent report published by the Home Builders Federation (HBF) has revealed that new build houses will save owners an average of over £3,100 in annual energy costs compared with typical older properties when the Government’s Energy Price Guarantee (EPG) cap increases on 1 April 2023.

Let’s take a closer look and explore the advantages of owning a new build home when it comes to cutting down on your energy bills.

What is energy efficiency?


So, what is energy efficiency? Energy efficiency is the use of less energy to perform the same task or produce the same result. By choosing an energy-efficient new build home, you will not only reduce greenhouse gas emissions and use less energy to run your home, but you will also pay less on your energy bills.

The HBF’s report states that new build properties consume an average of 8,618 kWh per year, whereas older properties consume an average of 21,293 kWh per year. This saving is the equivalent of charging your electric car 211 times per year with a new build home. *

What is an EPC? 


If you’re in the market for a new home, chances are you’ve come across the term EPC. And with good reason – it’s become an increasingly important factor in today’s climate, especially when making a purchasing decision. But what exactly is an EPC, and what does it measure?

Put simply, an EPC is a home energy survey that reveals how energy efficient a property is. It provides a rating on a scale of A (very efficient) to G (inefficient) and includes recommendations on how to improve the property’s energy efficiency. Not only is it a legal requirement for those selling, leasing, or renting a property, but it can also give you an indication of how much the property will cost you in energy bills.

The HBF report revealed that a whopping 85% of new build homes were rated A or B, while less than 4% of existing dwellings reached the same standards.

At Castle Green Homes, we pride ourselves on building high-quality homes with EPC ratings of A and B standards. Across all our developments, we prioritise sustainability through thoughtful design, ensuring our homes are thermally efficient without relying on add-on measures – keeping your costs down and your home warm.

  • 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 ever-increasing energy bills will be a top priority for many homeowners or first-time buyers looking to get on the property ladder. But improving the environmental impact on our planet is also a desirable prospect.

The HBF report outlines last year’s new build home purchasers reduced carbon emissions by an average of 2.2 tonnes a year per home. Saving a whopping 570,000 tonnes compared to if they had bought an equivalent older property.

At Castle Green Homes, we are always determined to improve our green credentials. As part of this commitment, we have achieved carbon neutrality and net-zero status and have set our sights on reducing our emissions by at least 50% by 2030. By focusing on improving the energy efficiency of our homes, our customers will not only reduce their energy bills but also significantly lower their carbon footprint. We believe that by constantly striving to innovate and improve, we can create a more sustainable future for all.
