Buying a newly built property involves a mortgage process that differs from purchasing an existing home in several important respects.
From extended offer periods to specialist government schemes, understanding how financing works for new builds will help you move forward with confidence.
With the UK market evolving quickly and some significant lender changes introduced in mid-2025, there’s more support available for buyers than there has been for some years.
Understanding New Build Mortgages
New-build homes are treated differently by mortgage lenders, and it’s important to understand why before you begin your search.
Because newly built properties carry a small risk of initial depreciation and can be harder to value precisely, lenders often apply stricter criteria – including higher deposit requirements and independent valuations.
Some lenders limit the loan-to-value (LTV) ratios available on new builds compared to older stock, and mortgage offer periods need to be longer to accommodate construction timelines.

Recent Developments and Mortgage Support for New Build Homes
The most significant recent development for new-build buyers came in June 2025, when Nationwide increased the maximum loan-to-value on new-build houses to 95%, positioning itself as the only major UK lender offering borrowing up to six times income at that level.
Alongside this, mortgage offers on new-build properties were extended to nine months without requiring an extension (up from the previous six months plus a 45-day extension), giving buyers and developers considerably more breathing space during the construction phase.
The changes were designed to address a gap that has existed since the end of Help to Buy, with mortgage-backed purchases of new-build properties having fallen by around a third compared with 2022 due to deposit constraints and affordability pressures.
Government Schemes and Deposit Solutions
Several schemes remain available to support buyers with smaller deposits.
First Homes offers eligible first-time buyers a minimum 30% discount on new-build properties in England.
Shared Ownership enables you to purchase a share of a property and then pay rent on the remainder, significantly reducing the upfront cost.
The Deposit Unlock scheme enables buyers to purchase properties with a 5% deposit, up to £750,000, backed by participating housebuilders.
The Lifetime ISA provides a 25% government bonus on savings of up to £4,000 per year for first-time buyers, and a government-backed mortgage guarantee scheme has extended access to 95% LTV mortgages more broadly across the market.
Practical Steps and Specialist Advice
Securing a mortgage on a new build follows a clear sequence: reserving the property, obtaining a mortgage in principle, submitting a full application and exchanging contracts ahead of completion.
Understanding how new-build mortgages work in practice before you begin will prevent surprises at each stage.
Builder incentives (such as contributions to stamp duty or upgraded fixtures) can affect what lenders will accept, so these need to be disclosed carefully.
Construction delays are not uncommon, making extended offer periods from certain lenders particularly valuable.
Throughout this process, working with a mortgage broker experienced in new builds is one of the most practical steps you can take, as they will understand lender-specific criteria and help you meet deadlines without unnecessary stress.
