Research reveals new build homeowners save as much as £420 per year, while household carbon emissions are cut by up to 74%.

To mark New Homes Week 2026, Barratt and David Wilson Homes East Scotland, part of the UK’s leading housebuilder Barratt Redrow, have increased their Part Exchange incentive from £500 to £1,000 for people who are still living in their existing property when it is sold*.
With Part Exchange, when prospective homeowners purchase a new home with Barratt Homes or David Wilson Homes, the housebuilder becomes the guaranteed buyer for their existing property, taking the stress out of selling and helping them to move quicker and more easily.
Now in its 21st year, the annual New Homes Week campaign launched by the Home Builders Federation (HBF) aims to highlight the benefits of new build homes and provide a platform for the home building industry, homeowners and potential buyers to recognise the value of modern developments.
Barratt and David Wilson Homes East Scotland’s enhanced Part Exchange incentive comes as new research from the Home Builders Federation demonstrates new build homes are far more cost and energy efficient than second hand homes, with homeowners typically saving over £420 a year**.
Based on data from Octopus Energy, the UK’s largest energy supplier, the Watt a Save report shows that energy bills for new build homes are 21% less than typical older properties.
Thanks to increasingly sustainable building practices and technology, the majority of new homes achieve an A or B Energy Performance Certificate (EPC). As a result, new build homeowners spend around £1,574 a year on energy, compared with £1,995 on older homes that typically have a D rating. Meanwhile people living in F and G rated homes – such as some Victorian properties – typically spent 39% more on their overall energy bills last year, compared to the average new build homeowner.
The Watt a Save report has been released today (Friday 6 February) to support national New Homes Week’s ‘Power to Save’ day, providing key evidence for people looking at the long-term running costs of their next home, before they buy.
In addition to cutting running costs, the findings show new build homes are helping to cut household carbon emissions by up to 74% every year, compared to older properties, meaning today’s new build buyers can significantly lower their carbon footprint without changing their habits.

Andrew Morrison, Managing Director at Barratt Homes and David Wilson Homes East Scotland, said: “At Barratt and David Wilson Homes East Scotland, we’re committed to helping people move up or onto the property ladder.
“This New Homes Week, we’re highlighting our enhanced Part Exchange scheme, which removes the need for an onward chain and guarantees the sale of an existing home, taking the stress out of moving and helping buyers secure their ideal home.
“Our new homes across East Scotland are designed with energy efficiency and long-term performance at the forefront. Features such as solar panels, air source heat pumps, and modern insulation reduce running costs and environmental impact. Independent data shows how new-build homes outperform older properties, underlining the clear benefits of choosing a modern, future-proof home.”
Neil Jefferson, Chief Executive at the Home Builders Federation, said: “Buying a home marks a major milestone in our lives, yet for many, achieving that dream has become increasingly challenging.
“This New Homes Week we’re spotlighting the much-needed support home builders provide to make buying a new home more accessible – removing barriers and reducing uncertainty to make the goal of homeownership more achievable.
“By ensuring people understand their options and the benefits of buying a new build, we hope to empower more would-be buyers to take those steps to moving and beginning the next chapter of their lives.”
Barratt and David Wilson Homes are creating a range of new communities across East Scotland, including David Wilson Homes @ St Andrews in Fife, just a stone’s throw from world-renowned golf courses and beaches.
