With rising energy costs and tighter environmental regulations across the UK, energy efficiency has become a major priority for buyers, tenants, landlords and investors alike. If you are considering purchasing or renting a property in 2026, particularly in London, choosing a new-build home could significantly reduce your annual energy bills compared to an older property.
But how much can you actually save — and why?
New build properties completed in 2026 are designed to meet the latest UK building regulations, including stricter energy performance standards introduced as part of the government’s long-term net-zero strategy.
As a result, they are substantially more efficient than homes built even 10–15 years ago.
On average, new build homes are:
This combination dramatically reduces heat loss, lowers energy consumption and helps maintain a consistent indoor temperature throughout the year.
While exact savings vary depending on property size, usage and location, research consistently shows that new build homes can save households hundreds of pounds per year in energy costs.
Compared to older properties with lower EPC ratings (such as D, E or below), a modern new build home with an EPC rating of A or B can:
For many households, this can translate into savings of up to 40–50% on annual energy bills compared to older, less efficient properties.
In cities such as London — where utility costs are typically higher — these long-term savings can make a meaningful difference to monthly outgoings.
Energy Performance Certificates (EPCs) are becoming increasingly important, particularly for landlords. Under current UK regulations, rental properties must meet a minimum EPC rating of E. However, the government continues to consult on raising this threshold in the coming years.
Most new build homes achieve:
For landlords and property investors, this provides reassurance and reduces the likelihood of expensive retrofit works to improve energy efficiency later on.
For buyers, a high EPC rating supports stronger resale appeal and future-proofs the property against regulatory change.
Energy efficiency is no longer simply a lifestyle preference — it is a financial consideration.
Lower running costs make properties:
In luxury London developments, high EPC ratings and sustainable design are increasingly viewed as essential features rather than optional extras.
For overseas buyers and investors, new builds also offer the added advantages of:
With the UK’s continued commitment to reducing carbon emissions, building standards are tightening year by year.
Properties completed in 2026 are expected to benefit from:
This means homes built in 2026 are likely to outperform many properties completed just a few years earlier, making them a strong choice for both owner-occupiers and landlords.
If you are deciding between a period property and a new development, it is important to consider:
While period homes offer charm and character, new build homes provide efficiency, predictability and long-term cost savings.
For landlords, this can mean fewer compliance concerns.
For homeowners and tenants, it can mean noticeably lower monthly outgoings.
