Want to buy a new build home in the UK but unsure where to start? Our guide outlines buying process, including the benefits of a new build and any pitfalls.

Key Takeaways

  • New build homes offer energy efficiency, modern features, and access to government or developer-backed schemes that can make buying more affordable

  • Potential mortgage delays, snagging issues, and complex warranties mean research and legal advice are essential

  • Government schemes like First Homes and Shared Ownership, can significantly reduce upfront costs, but each comes with specific eligibility criteria

  • Management or estate fees may still apply even to freehold homes, so always clarify all ongoing costs before committing

Buying a new build property in the UK offers the promise of modern design, energy efficiency, and a blank canvas for your new home

However, the process differs from buying an existing property and there are key points to understand before deciding on a new build.

Research new build developers thoroughly

Your new build home will only be as good as the developers that built it, so investigate the reputation of developers by:

Reviewing past projects. Visit completed developments to assess build quality

Checking online reviews. Platforms like Trustpilot, HomeViews and the Home Builders Federation provide insights into customer experiences

Engaging with current residents. Speak to homeowners in existing developments about their experiences, including any issues and how they were resolved

Explore government and developer help to buy schemes

There are several initiatives that can assist new build home buyers, even if you’re not a first-time buyer. These include:

The First Homes scheme is a government-backed initiative aimed at helping first-time buyers and key workers purchase a new-build home at a discount of 30–50% off the market value.

These homes are only available through participating developers in England and must be the buyer’s main residence. The discount is passed on to future buyers, ensuring ongoing affordability.

You must be a first-time buyer, have a household income under £80,000 (£90,000 in London), and be purchasing a property valued at £250,000 or less (£420,000 in London) after the discount.

Local councils may apply additional criteria like living or working in the area.

Shared Ownership allows buyers to purchase a share of a new-build property (typically between 10% and 75%) and pay rent on the remainder to a housing association.

You can increase your share over time through a process called ‘staircasing’ until you potentially own 100% of the home. It’s ideal for buyers who can afford mortgage repayments but not a big deposit upfront.

You must be a first-time buyer, a previous homeowner unable to buy again, or an existing shared ownership resident. Your household income must be under £80,000 (£90,000 in London). The home must be your only residence.

The Own New Rate Reducer scheme is a developer-supported mortgage initiative designed to lower monthly payments. It involves developers contributing funds (often 3–5% of the purchase price), which are passed to the mortgage lender to effectively buy down your mortgage interest rate. This results in lower monthly repayments for the initial fixed-rate period (typically 2–5 years).

Available to all types of buyers purchasing new-build properties with participating developers and lenders. There are no income caps, and buyers must pass affordability checks with the lender. It is particularly useful in a high-interest environment to improve affordability short-term.

Deposit Unlock is a scheme created by the Home Builders Federation (HBF) and reinsurance provider Gallagher Re, enabling buyers to purchase a new-build home with just a 5% deposit. It’s open to both first-time buyers and home movers, and it applies to properties from participating developers.

The scheme works by providing lender insurance to reduce the risk of low-deposit lending, which means buyers get access to 90–95% loan-to-value mortgages at competitive rates.

It’s open to anyone buying a new-build home up to £750,000, subject to lender affordability assessments. Participating developers and mortgage lenders must be used.

The Lifetime ISA is a government savings product that helps people save towards their first home (or retirement). You can deposit up to £4,000 per year, and the government adds a 25% bonus, up to £1,000 annually. The money can be withdrawn penalty-free to buy your first home after 12 months of saving.

You must be 18–39 years old when opening the account. The home must cost £450,000 or less, and the LISA must be used with a residential mortgage, not a buy-to-let. You must be a first-time buyer and intend to live in the home. Withdrawals for other reasons incur a 25% penalty.

In addition to official schemes, many house builders offer their own incentives to attract buyers. These come on a case-by-case basis and may include:

  • Covering a portion of your mortgage for the first 6–12 months

  • Paying 5–10% of your deposit

  • Covering your Stamp Duty Land Tax (SDLT)

  • Furniture packs or upgrades, including white goods and flooring

  • The developer buying your current home directly to facilitate a move

Freehold vs leasehold: Know what you're buying

Before committing to a new build property, it’s vital to understand whether it is being sold as freehold or leasehold, as this affects your rights, responsibilities, and long-term costs.

With a freehold property, you own both the building and the land it stands on outright. There are no ongoing ground rents or service charges.

In contrast, a leasehold property means you own the building for a fixed term, but not the land it’s built on.

This arrangement is more common with new-build flats, but some new-build houses have controversially been sold leasehold too.

As a leaseholder, you may face:

  • Ground rent charges (although these are now banned for most new leases in England and Wales)

  • Service charges for communal areas and maintenance

  • Restrictions on alterations or subletting

  • Lease extension costs in future decades

Always ask the developer whether the property is leasehold or freehold and review the lease terms carefully with your solicitor.

Beware management fees

Buyers of new-build homes – whether leasehold or freehold – should be cautious of estate or management fees, which cover the upkeep of communal areas like roads, green spaces, or lighting.

These charges can apply even to freehold properties and are often uncapped, meaning they can rise unpredictably and are usually managed by a private company rather than the local authority.

Budget for additional costs

Beyond the deposit, consider you may also have to pay additional fees such as:

  • Stamp Duty Land Tax (SDLT)

  • Legal fees

  • Mortgage fees

  • Surveys

  • Removal costs

Obtain a Mortgage Agreement in Principle (AIP)

An AIP gives you a clear idea of how much you can borrow, making you a more credible buyer. It's typically valid for 60–90 days and can be obtained from banks, building societies, or mortgage brokers.

Getting a mortgage for a new-build property can be more complicated due to factors like build delays, which may cause your mortgage offer to expire before the home is ready.

If you're buying off-plan (i.e. before construction is complete), lenders may be cautious about valuing a property they can’t inspect yet, and you might need to reapply or extend your mortgage offer if the build overruns its expected timeline.

Engage a solicitor or conveyancer early

Choose a legal professional experienced in new-build transactions to ensure the terms are fair and your interests are protected.

They will conduct necessary searches on planning permissions, local developments, and environmental factors and help manage the timelines and financial transactions. You can find out more about the role of a conveyancer with our guide.

Understand the warranty

New build homes in the UK should come with warranties that should cover any issues that arise in the years after the sale. The most common warranty is the NHBC Buildmark, which provides a 10-year cover divided into:

During the first two years after legal completion, your builder is responsible for rectifying any defects arising from their failure to meet NHBC's Technical Standards. If the builder fails to address these problems, NHBC's Resolution Service can intervene to ensure necessary repairs are made.

From the third year onwards, the warranty provides insurance cover for specific structural defects such as problems with foundations, roofs, or load-bearing walls. It's important to note that this period covers only damage resulting from breaches of NHBC's Technical Standards.

Other providers offer similar 10-year warranties, but coverage details can vary, so review your specific policy documents carefully.

Remember, these warranties do not replace standard home insurance, which is necessary to cover risks like fire, theft, or accidental damage.

Note the reservation fee

When you're ready to secure a new-build home, you’ll typically be asked to pay a reservation fee, usually between £500 and £2,000.

This fee holds the property for a set period and is usually deducted from the final purchase price. However, it's important to check whether the fee is refundable and how long the cooling-off period lasts, in case you change your mind or encounter delays.

Arrange insurance

You're responsible for insuring the property from the time your exchange contracts.

Challenges with new builds can include new addresses not being immediately recognised by insurers and the Royal Mail may need to be contacted to make sure the address is on its database.

As well as buildings insurance, you might also want to take out contents insurance from the day you move in.

Conduct a snagging survey

Even new homes can have defects. A snagging survey identifies issues for the developer to rectify. Common snags include:

  • Paintwork Issues such as drips, cracks, or uneven finishes

  • Plumbing problems, from leaks or poor water pressure

  • Electrical faults, including non-functioning sockets or switches

  • Doors or windows that don't close properly

  • Surface damage from scratches on glass to gouges in countertops

While you can check for these yourself, a professional snagging company can be hired, especially if you're unfamiliar with construction standards.

Settle into your new home

As well as registering utilities such as gas, electricity, water, and council tax, and updating your address with banks, employers and friends and family, you should also keep an eye out for any defects or problems with the property – and report them to the developer or warranty provider when spotted.

What are the advantages and disadvantages of buying a new build home?

There are pros and cons of buying a new build, and it often comes down to personal preference:

  • Everything is brand new, so repairs and maintenance should be minimal in the early years

  • Most new builds come with a 10-year structural warranty for peace of mind

  • You can often choose finishes, fixtures, and upgrades to suit your taste

  • New builds are usually more energy efficient, helping to keep utility bills down

  • There’s no upward chain, reducing the risk of the sale falling through

  • Government schemes and developer incentives can make them more affordable

  • New builds may come at a premium compared to similar older homes

  • Room sizes and storage space can be smaller than in period properties

  • Properties may lose value, especially if bought at the peak of a development

  • Completion delays can occur, especially with off-plan purchases

  • Snagging issues and build quality concerns may arise post-completion

  • Freeholders may still face estate management fees for shared spaces

Our expert says

Buying a new-build home can offer energy efficiency, low maintenance, and access to government schemes or developer incentives, particularly for first-time buyers. However, buyers should be cautious of potential downsides, including premium pricing, smaller room sizes, and delays in completion, especially with off-plan properties. A new build isn’t always the perfect fit, but with due diligence, it can be a smart and secure investment.
