Alexander Hall’s internal data showed first-time buyers (FTBs) made up 59% of new-build transactions, but homemovers accounted for 22% and buy-to-let (BTL) investors 19%.
The research also found 27% of new-build buyers were aged 40 or over.
Studios and one-bed flats made up 41% of sales, but two-bed properties were the most popular at 45%.
Three-bed homes accounted for 11% of transactions.
FTBs benefited from chain-free properties, reduced risk of delays, and access to schemes such as Deposit Unlock and Own New.
Homemovers bought move-in-ready homes, with the option to buy off-plan and influence design.
Energy efficiency was also highlighted, along with locations close to green spaces and transport.
Landlords saw higher-quality tenants and higher rents for new-builds, especially where there were co-working spaces or smart technology.
All new-builds offered energy performance certificate (EPC) A or B ratings, meeting rental standards set for 2030.
Lower maintenance costs and 10-year warranties were also reported.
Lender data showed improved mortgage accessibility for new-builds with energy-efficient products, lower rates, and greater borrowing potential.
There were more low-deposit options, acceptance of developer incentives, and longer mortgage offer periods for off-plan purchases.
Lending flexibility was reported for professional occupations, key workers, and FTBs.
Stephanie Daley, director of partnerships at Alexander Hall, said: “With rising energy costs and stricter regulations on property standards, new-builds offer first-time buyers, homeowners, and landlords a future-proof solution.
“Not only are they more energy-efficient, saving hundreds on bills each year, but they also come with developer incentives, modern amenities, and fewer maintenance concerns.
“In today’s market, buying a new-build is not just a smart financial decision, it’s a lifestyle upgrade.”
Daley added: “We’ve also seen lenders introduce a range of new products and initiatives to help the nation’s homebuyers when it comes to securing a mortgage on a new-build property, further boosting appeal beyond existing incentives.
“The combination of low-deposit options, enhanced income multiples, and specialist purchasing schemes is creating opportunities for buyers who may have thought a new-build was out of reach.
“With the right guidance, now could be one of the best times in recent years to secure a new-build home.”
