Why New-build Homes Are Far More Energy-Efficient Than Older Properties

Why New-build Homes Are Far More Energy-Efficient Than Older Properties Featured Image

As temperatures begin to drop in November and the heating clicks on for the first time in months, many homeowners start to notice just how much energy their property uses — and how much it costs to stay warm. Rising energy bills and colder weather are two excellent reasons to choose a new-build home which is designed to keep you comfortable and efficient all year round.

In the UK housing market, one of the strongest arguments in favour of buying a new-build property is its superior energy efficiency.

According to the Office for National Statistics (ONS), the age of a property is the single most important factor in a home’s energy efficiency. Homes built from 2012 onwards are much more likely to have a high Energy Performance Certificate (EPC) rating (C or above) compared with older homes.

The Home Builders Federation (HBF) “Watt a Save!” report found that homes built as new use far less energy annually compared to older properties — around 9,414 kWh for new builds, versus 21,040 kWh for older homes. The same report shows that new build buyers can save over £2,000 per year on energy bills compared to owners of equivalent older homes.

In short: newer homes are warmer, cheaper to run, and far better for the planet.

Why New Homes Perform Better

Modern construction standards and technology make a major difference in thermal performance:

  • Enhanced insulation with roofs, walls and floors that use advanced materials to reduce heat loss.
  • Airtight design means fewer draughts and more controlled ventilation mean less wasted energy.
  • High-performance glazing keeps heat in and cold out.
  • Efficient heating systems, with modern boilers and smart thermostats to optimise the use of energy throughout the house.
  • No hidden inefficiencies – unlike older homes, new builds don’t require costly upgrades to improve performance.

How Erris Homes Deliver Enhanced Energy Efficiency

At Erris Homes, energy efficiency is built into every home from the ground up. Our homes are designed not just to meet, but to exceed modern environmental standards, offering potential savings of up to £2,600 per year on energy bills.

Some of their key energy-saving features include:

  • Super-insulated roof spaces using high-spec PIR insulation.
  • Intelligent double glazing that retains warmth while maximising natural light.
  • Airtight construction with post-completion testing for optimal performance.
  • High-efficiency boilers and intelligent heating controls.
  • Low-energy lighting and smart fixtures throughout.
  • At developments such as Calder Mews, additional sustainability features like solar panels and EV charging points further reduce carbon emissions and day-to-day living costs.

What This Means for You

Choosing a new-build home means lower running costs and protection from rising energy prices. It means a warmer, more comfortable home with consistent temperatures and fewer draughts.

You’ll also have a smaller carbon footprint, helping the environment while saving money, as well as less maintenance and retrofit work. It’s also an investment in better long-term value as energy efficiency becomes an increasingly important selling point.

With our  forward-thinking design, quality construction and commitment to sustainability, Erris Homes deliver properties that are warmer, cheaper to run and built for the future. As the nights draw in and the cold settles, that’s a thought you can really warm to!
