Is a New Build Right for You?
Before diving into the buying process, it's worth understanding what you're getting — and what you're giving up — by choosing a new build over an existing property.
What You Get with a New Build
- Modern construction standards — built to the latest building regulations including energy efficiency (Part L 2022), fire safety (Part B), electric vehicle charging (Part S), and overheating protection (Part O)
- Energy efficiency — most new builds achieve EPC A or B, saving £500-£1,000+ per year on energy compared to older homes. See our running costs guide
- 10-year structural warranty — NHBC Buildmark or equivalent covers major defects. See our warranty guide
- No chain — you're buying directly from the developer, eliminating the risk of chains collapsing
- Customisation — if you buy early enough, you can choose finishes, upgrades, and sometimes layout options
- Developer incentives — contributions worth £5,000-£30,000+ towards stamp duty, legal fees, fixtures, or mortgage costs
- Low maintenance — everything is new, so expect minimal repair costs for at least 5-10 years
What You Give Up
- Paying a premium — new builds typically cost 10-25% more than comparable existing properties
- Space and character — rooms in new builds are often smaller than in older homes, and you won't get period features or mature gardens
- Snagging issues — new builds frequently have defects that need fixing, sometimes dozens of them
- Developer timelines — you work to their schedule, not yours. Completion dates can move
- Limited negotiation — you negotiate incentives, not price. The developer controls the deal structure
- Premium deflation — the new build premium erodes in the first 1-3 years, meaning slower price growth initially

Finding the Right New Build
Finding the right development is about more than price and location. The developer you buy from, the phase of the development, and even the specific plot you choose all affect your experience.
Where to Search
- New build specialist platforms — search by location, price range, property type, and developer across verified developments
- Developer websites — each major housebuilder has a development finder on their site
- Rightmove/Zoopla — filter for new builds, but listings are mixed with resale properties
- Local authority planning portals — find developments before they're marketed by checking recent planning permissions
Researching the Developer
The developer's reputation directly affects build quality, after-sales service, and your overall experience. Check:
- HBF star rating — the Home Builders Federation customer satisfaction survey rates builders from 1-5 stars
- Trustpilot and Google reviews — look for patterns rather than individual complaints
- NHBC registration — confirms the builder meets warranty provider standards
- Previous developments — visit one of their completed sites (not the show home) to see the finish quality 2-3 years in
- Financial stability — check Companies House for accounts. A developer going bust mid-development creates serious problems
Choosing a Plot
Not all plots on a development are equal. Factors that affect value and liveability include:
- Orientation — south or south-west facing gardens get the most afternoon and evening sun
- Position on the site — corner plots are often larger but may have more public footfall. Plots backing onto open space have better outlooks
- Phase — early phases may have construction noise for years. Later phases benefit from completed infrastructure but may have less choice
- Proximity to roads — plots near main roads or site entrances experience more traffic noise
- Plot premium — developers charge extra for desirable plots. Typical premiums range from £2,000 to £20,000+
Visiting Developments and Show Homes
Show homes are designed to sell, not to represent what your home will actually look like on completion.
What to Watch For in Show Homes
- Furniture sizing — show home furniture is often 75-85% standard size to make rooms look larger
- Mirrors and lighting — strategically placed to create an illusion of space and brightness
- Upgrades on display — premium kitchens, flooring, and fixtures shown may not be included in the standard price
- No personal items — no bins, laundry baskets, or clutter that reveal how the space functions day-to-day
What to Ask the Sales Adviser
See our comprehensive 100+ Questions to Ask guide for the full checklist. Key questions at first visit include:
- What is included in the base price vs shown as upgrades?
- What is the estimated completion date for available plots?
- What incentives are currently available?
- What warranty provider covers this development?
- What are the annual service charges and estate charges?
- Is the property freehold or leasehold?
- Which plots are still available and what are the plot premiums?
Beyond the Show Home
Visit the development at different times of day and on different days of the week. Walk around completed areas. Talk to residents who have already moved in. Check the surrounding area for schools, transport links, shops, and any planned developments nearby.
Financing Your Purchase
Getting your finances right is the foundation of a successful new build purchase. New builds have specific financial requirements that differ from standard property purchases.
Your Deposit
You'll need to provide deposits at two stages:
| Stage | Amount | When | Notes |
|---|---|---|---|
| Reservation fee | £500-£2,000 | When you reserve | Deducted from purchase price. May be non-refundable. See reservation fee guide |
| Exchange deposit | 5-10% of purchase price | At exchange of contracts | Held in solicitor's client account until completion. Lost if you pull out post-exchange |
| Completion balance | Remainder (covered by mortgage + remaining deposit) | On completion day | Transferred by your solicitor on the day |
For full deposit guidance including how to save, where to hold funds, and how deposit sizes affect mortgage rates, see our deposit guide and deposit requirements explained.
Your Mortgage
New build mortgages work differently from standard mortgages in several important ways:
- Lower maximum LTV — many lenders cap new build mortgages at 85-90% LTV (instead of 95% for resale properties), meaning you need a larger deposit
- Offer validity — mortgage offers typically last 6 months. Off-plan purchases that take longer will require an extension or reapplication
- Incentive caps — lenders limit the value of developer incentives they'll accept (typically 5% of property value at 85-90% LTV)
- Valuation specifics — the lender's valuer assesses the property's worth independently. Down-valuations are common on new builds
- Not all lenders do new builds — some lenders restrict lending on certain property types (high-rise flats, studios, modular construction)

Using a Mortgage Broker
A broker experienced with new builds is strongly recommended. They understand which lenders accept specific property types, how to handle incentive declarations, and can manage offer extensions if your completion is delayed. The developer will often recommend a broker — you're not obligated to use them, and an independent broker may find better deals.
Government Schemes and Assistance
Several government-backed schemes can help you buy a new build, particularly if you're a first-time buyer.
Current Schemes (2026)
| Scheme | How It Works | Who It's For | Key Limit |
|---|---|---|---|
| Shared Ownership | Buy 25-75% share, pay rent on the rest. Staircase to full ownership over time | Household income under £80,000 (£90,000 in London) | Rent + mortgage must be affordable |
| First Homes | Minimum 30% discount on market value, locked in for future sales | First-time buyers, local connection priority, key workers | £250,000 after discount (£420,000 London) |
| Own New Rate | Developer subsidises your mortgage rate for a fixed period (typically 2-3 years) | Any buyer on participating developments | Developer-specific, not government-funded |
| Lifetime ISA | Save up to £4,000/year, get 25% government bonus (£1,000/year) towards first home purchase | First-time buyers aged 18-39 | Property price up to £450,000 |
| Right to Buy (council tenants) | Discount on council home purchase — can sometimes be used towards new build via replacement programmes | Qualifying council tenants | Discount varies by region and tenure length |
Help to Buy (Closed)
The Help to Buy equity loan scheme closed to new applications in October 2022 (completions by March 2023). It is no longer available for new purchases. If you have an existing Help to Buy equity loan, see our Help to Buy legacy guide.
Specialist guides:
Developer Incentives
Developers rarely reduce their headline prices. Instead, they offer incentives — contributions, upgrades, or financial assistance that reduce your costs without affecting the recorded sale price.
Common Incentive Types
- Stamp duty paid — developer pays your SDLT bill (worth £2,500-£15,000+ depending on price)
- Legal fees paid — covers your solicitor's costs (typically £1,500-£3,000)
- Flooring/kitchen/bathroom upgrades — upgraded specifications included in the price
- Furniture packages — especially common on apartment developments
- Deposit contributions — developer provides part of your exchange deposit (careful: lenders view this differently)
- Mortgage rate subsidy (Own New Rate) — developer subsidises a lower interest rate for 2-3 years
- Part-exchange — developer buys your existing home to remove chain risk
The Catch
Incentives sound generous, but there are important caveats:
- Lenders cap total incentives at 3-5% of the property value (depending on LTV). Anything above this and the lender reduces the property's valuation
- Some incentives are factored into an inflated price — the stamp duty paid may be offset by a higher purchase price
- Incentive conditions may be hidden in the fine print
Specialist guides:
The Legal Process
New build conveyancing is more complex than standard property purchases. Your solicitor handles additional checks, documents, and negotiations that don't exist on resale purchases.
Why You Need a Specialist Solicitor
A solicitor experienced in new build transactions will:
- Review the developer's contract pack (which is heavily weighted in the developer's favour)
- Check planning permission conditions and building control sign-off
- Verify the warranty registration and coverage
- Review the lease terms (if leasehold) including service charges, ground rent, and management company
- Check road and sewer adoption status (Section 38/Section 104 agreements)
- Negotiate contract amendments where possible
- Flag any red flags in the legal pack before you exchange
The developer will recommend their own solicitor (or a "panel" solicitor). You are not obligated to use them, and an independent solicitor acting solely in your interest is strongly recommended.
Specialist guides:
Reservation
Reservation is the first formal step in buying a new build. You pay a fee to take the property off the market while the legal and financial process begins.
What Happens at Reservation
- You choose your plot and sign a reservation agreement
- You pay a reservation fee of £500-£2,000 (sometimes more for premium properties)
- The developer removes the property from active marketing
- You typically have 28 days to exchange contracts (though this can be extended)
- You must appoint a solicitor and mortgage broker immediately — the clock is ticking
Key Points
- The reservation fee is usually deducted from the purchase price on completion
- Read the reservation agreement carefully — it may restrict your ability to get a refund if you withdraw
- Under the Consumer Code for Home Builders, you should have a cooling-off period, but the terms vary
For full details, see our reservation fee guide and what happens in the critical 28 days after reservation.
Exchange of Contracts
Exchange is the point of no return. Once you exchange contracts, you are legally committed to buying the property and the developer is legally committed to selling it to you.
What Happens at Exchange
- You pay the exchange deposit (usually 10% of the purchase price, sometimes 5%)
- Your solicitor and the developer's solicitor formally exchange the signed contracts
- A completion date is set (or an estimated date range if the property isn't finished)
- The contract includes a longstop date — the absolute latest date by which completion must happen. If the developer misses this, you can withdraw and get your deposit back
After Exchange
- If you withdraw after exchange, you lose your deposit (10% of the purchase price) and may face additional claims from the developer
- If the developer fails to complete by the longstop date, your solicitor can serve a notice to complete and ultimately rescind the contract
- Your mortgage offer needs to remain valid through to completion — if there are delays, you may need an extension
See our exchange of contracts guide and off-plan exchange risks.
The Waiting Period
If you've bought off-plan, there may be weeks or months between exchange and completion while the developer finishes construction.
During the Build
- Developer updates — you should receive regular progress updates, though quality varies between developers
- Site visits — some developers allow pre-completion visits at key build stages. Always ask
- Mortgage monitoring — check your mortgage offer expiry date regularly. If completion will be delayed, contact your broker early to arrange an extension or reapplication
- Insurance — arrange buildings insurance to start from the completion date. Compare quotes in advance
- Utility registration — the developer should provide details of which energy, water, and broadband providers serve the site
If There Are Delays
Construction delays are common on new build developments. Your legal protections depend on the contract terms:
- Estimated completion date — not legally binding. The developer has until the longstop date
- Longstop date — legally binding. If the developer misses this, you can withdraw with your deposit returned
- Notice to complete — a legal mechanism your solicitor can use to force completion within a set period (usually 10 working days)
- Compensation — rarely offered unless the contract specifically provides for it
Completion Day
Completion is the day ownership transfers to you and you get the keys.
What Happens
- Your solicitor sends the completion funds to the developer's solicitor (mortgage money + your remaining deposit)
- Once funds are received and confirmed, the developer releases the keys — usually by mid-afternoon
- Your solicitor registers the transfer of ownership with the Land Registry
- Stamp duty must be paid within 14 days of completion
On the Day
- You'll typically collect keys from the site sales office
- The developer should provide a home demonstration — showing you how the heating, ventilation, appliances, and security systems work
- You'll receive a home user guide with warranty information, appliance manuals, and emergency contact numbers
- Take meter readings for gas, electricity, and water immediately
- If possible, arrange a snagging inspection before moving furniture in (see below)
For a full hour-by-hour breakdown, see our completion day guide.
Snagging and Defects
Even brand-new homes have defects. A professional snagging inspection typically finds 50-200+ issues ranging from cosmetic blemishes to functional problems.
What Snagging Covers
- Cosmetic defects — scratched glass, poor paintwork, chipped tiles, uneven grouting, marks on walls
- Functional issues — doors not closing properly, drainage problems, heating not working correctly, insufficient ventilation
- Specification shortfalls — items missing or different from what was promised in the contract
- Structural concerns — cracks in walls, uneven floors, roof issues (rare but serious)
When to Snag
Ideally, arrange a professional snagging inspection before you move in — an empty house is much easier to inspect. Many developers allow a pre-completion inspection. If not, do it in the first week before furniture obscures potential issues.
Your Rights
During the 2-year defects liability period, the developer must fix any defects caused by their workmanship or materials. If they refuse or delay unreasonably, you can escalate through the warranty provider's complaints process.
Specialist guides:
Your First Year
The first year in a new build is different from moving into an established home. The building is still settling, drying out, and bedding in.
What to Expect
- Drying out period — a new build contains thousands of litres of construction moisture. It takes 9-12 months for the building to fully dry out. During this time, you may see hairline cracks in plaster, stiff doors, and condensation on windows. Most of this is normal
- Shrinkage cracks — small cracks in plaster and at junctions between walls and ceilings are normal settlement and not structural defects
- Landscaping — gardens are typically turfed but not established. Expect thin topsoil and immature planting
- Ongoing construction — if you move into an early phase, construction will continue around you. This means noise, dust, construction traffic, and incomplete communal areas
- Snagging follow-up — chase any reported defects that haven't been fixed. Keep records of all communications
Maintenance
Even though everything is new, some maintenance is required from day one:
- Register your boiler and appliances for warranty
- Bleed radiators (air gets trapped during installation)
- Check trickle vents on windows are open for ventilation
- Use extraction fans when cooking and bathing to manage moisture
- Don't redecorate for at least 12 months — wait for the building to dry and settle
For full first-year advice, see Your First Year in a New Build: What Nobody Tells You and our year-by-year maintenance schedule.

Common Problems and How to Handle Them
Most new build purchases complete without major issues, but problems do occur. Here are the most common and what to do about them.
| Problem | How Common | What to Do | Guide |
|---|---|---|---|
| Down-valuation | Common (15-25% of new build purchases) | Negotiate with developer, increase deposit, or challenge valuation | Mortgage problems guide |

Guide by Buyer Type
Different buyers face different challenges when purchasing a new build. Here's where to focus based on your situation.
First-Time Buyers
As a first-time buyer, new builds offer several advantages: no chain, predictable costs, potential government scheme eligibility, and developer incentives designed specifically for first-time buyers. Your biggest challenges are typically the deposit requirement and understanding a process you've never been through before.
- First-Time Buyer's Complete Guide
- New Build vs Older Property for First-Time Buyers
- How Much Does It Really Cost?
- 15 Costliest Mistakes to Avoid
Home Movers
If you're selling an existing home to buy a new build, your main considerations are timing (can you align your sale with the new build completion?), part-exchange options (the developer buys your existing home), and whether the new build premium is justified given your experience of property ownership.
Buy-to-Let Investors
New builds in the right locations can make excellent rental properties — low maintenance, modern specifications, and strong tenant demand. But the new build premium and potential service charges eat into yields. Factor in the 5% additional property surcharge on stamp duty and stricter buy-to-let mortgage criteria.
Downsizers
New build apartments and bungalows offer low-maintenance living with modern accessibility standards (Part M). Key considerations include ongoing service charges, lease terms, and whether the development has lift access and level access throughout.
Frequently Asked Questions
How long does it take to buy a new build home?
For a completed property: typically 6-12 weeks from reservation to completion. For an off-plan property: 6-24+ months depending on the build stage when you reserve. See our buying timelines guide for detailed week-by-week breakdowns.
Can I pull out after reserving a new build?
Yes, before exchange of contracts. You may lose your reservation fee (£500-£2,000). After exchange, pulling out means losing your deposit (5-10% of the purchase price) and potentially facing legal claims. See our reservation fee guide.
Do I need a specialist solicitor for a new build?
Strongly recommended. New build conveyancing involves additional complexity — developer contracts, warranty verification, planning checks, adoption status, lease review (for flats) — that standard conveyancers may not handle well. See our guide to choosing a solicitor.
Are new build mortgages harder to get?
Not harder, but different. Lenders apply specific criteria to new builds — lower maximum LTV, incentive caps, property type restrictions, and offer validity concerns for off-plan. A broker who specialises in new builds navigates these issues. See our mortgage guide.
What is the biggest risk of buying a new build?
The single biggest financial risk is down-valuation — the lender's surveyor valuing the property below the purchase price. This can leave you needing to find thousands of pounds extra for the deposit. The biggest practical risk is construction delays on off-plan purchases, which can cause mortgage offers to expire. See our mortgage problems guide.
Should I use the developer's recommended solicitor or broker?
You can, but you're not obligated to. Developer-recommended professionals may have a commercial relationship with the developer. An independent solicitor and broker act solely in your interest. That said, developer-recommended professionals often have experience with that developer's specific contract terms and processes.
What is a longstop date?
The longstop date is the absolute latest date by which the developer must complete and hand over the property. If they miss it, you can withdraw from the contract and recover your deposit. Typical longstop dates are 6-18 months after the estimated completion date. See our contract guide.
Can I negotiate the price of a new build?
Developers almost never reduce the headline price because it would affect mortgage valuations on neighbouring plots. Instead, negotiate incentives — stamp duty contributions, upgrades, legal fees paid, or cashback. The value of negotiable incentives is typically 3-7% of the purchase price.
