Buying a New Build Home: 15 Things to Consider

Buying a new build home can offer modern design, better energy efficiency, fewer immediate repairs and the excitement of being the first owner. However, a brand-new property is not automatically problem-free.

Buyers need to investigate the developer, location, legal title, warranty, construction, ongoing charges and completion arrangements before paying a reservation fee.

Simple answer: Do not choose a new build using only the show home and monthly mortgage payment. Check what you will legally own, what is included in the price, how the development will change and what you will pay after moving in.

Mortgage Confirm lender acceptance and offer period Valuation differences or offer expiry
Legal work Check title, charges, roads and restrictions Unexpected ongoing costs
Pre-completion Inspect and prepare a snagging list Defects or unfinished work
Completion Collect documents, readings and keys Missing certificates or unclear aftercare

1. Research the Developer

Investigate the developer before becoming emotionally committed to a particular plot. A large national housebuilder may have extensive experience, while a smaller developer may offer a more individual service. Either can produce good or poor results.

Check:

  • Recently completed developments by the same builder
  • Reviews from people who have lived in their homes for at least a year
  • How quickly the developer responds to defects
  • Whether residents report repeated construction problems
  • The developer’s complaints procedure
  • Which new homes consumer code applies
  • Whether the developer is registered with the New Homes Quality Board

Customers who reserve with a registered developer after its activation date may be protected by the New Homes Quality Code and have access to the New Homes Ombudsman Service.

Practical tip: Reviews written immediately after collecting the keys may focus on the sales experience. Reviews written several months later often reveal more about build quality and after-sales support.


2. Investigate the Development and Local Area

A quiet plot today may be surrounded by construction for several years. Ask for the complete development plan rather than looking only at the current sales phase.

Find out:

  • How many homes will eventually be built
  • How many construction phases remain
  • Whether more blocks or houses are planned near your plot
  • The location of affordable housing and rental blocks
  • Where construction traffic will travel
  • Whether planned shops, schools or transport links are confirmed
  • Whether surrounding land has separate planning permission
  • The location of play areas, substations, pumping stations and bin stores

Search the local council’s planning portal using the development address and planning reference. Proposed facilities shown in marketing materials may be subject to planning, funding or future changes.


3. Choose the Plot Carefully

Properties of the same design can feel very different depending on their position. Visit the development at different times where access is permitted.

Consider the following plot details

  • Direction of the garden and natural light
  • Distance from neighbouring windows
  • Position of roads, paths and visitor parking
  • Nearby bin stores or communal entrances
  • Road noise and vehicle headlights
  • Sloping gardens, retaining walls and drainage
  • Privacy from future development phases
  • Mobile signal and broadband availability
  • Location of street lights, trees and service equipment

Check the legal title plan against the sales plan. Marketing drawings may not define the exact legal boundaries or ownership rights.


4. Do Not Assume the Show Home Is Standard

Show homes are professionally presented and may include upgraded flooring, premium kitchens, special lighting, fitted wardrobes, mirrors, landscaping and smaller display furniture.

Request a written specification for your exact plot confirming:

  • Kitchen units, worktops and appliances
  • Bathroom fittings and tiling
  • Flooring and carpets
  • Lighting and electrical sockets
  • Heating and ventilation systems
  • Garden turf, fencing and outside taps
  • Parking spaces, garages and storage
  • Electric vehicle charging equipment
  • Solar panels or other energy systems

Do not rely on a verbal promise from the sales team. Agreed extras and incentives should appear in the reservation or contract documents.


5. Compare the Price with the Local Market

A new home may carry a new build premium because it has not been occupied, includes a warranty and may offer modern finishes or developer incentives. Some of those first-owner benefits disappear when the property becomes a resale home.

Compare the price with:

  • Similar new build plots on the same development
  • Recently sold properties in the surrounding area
  • Comparable homes with similar floor space
  • Properties with equivalent parking and gardens
  • Expected service or estate charges

Use internal floor area as well as bedroom numbers. A compact three-bedroom new build may provide less usable space than an older two-bedroom property.

Price check: Free flooring or a developer contribution can be useful, but it should not distract you from checking whether the underlying purchase price is reasonable.


6. Calculate the Complete Cost

The advertised property price is only part of the new build home buying cost. Prepare a budget covering the purchase and the first year of ownership.

  • Reservation fee
  • Mortgage, broker and valuation fees
  • Conveyancing and search costs
  • Stamp Duty Land Tax, Land Transaction Tax or Land and Buildings Transaction Tax
  • Exchange deposit
  • Developer upgrades
  • Professional snagging inspection
  • Moving and furnishing costs
  • Buildings and contents insurance
  • Service charges or estate management charges
  • Council Tax, utilities and broadband

A freehold new build house may still have an annual estate charge for private roads, landscaped areas, drainage systems or play spaces. A leasehold flat will normally have a service charge and may also contribute towards a reserve fund.


7. Read the Reservation Agreement

The reservation agreement should identify the property, price, reservation fee, cancellation rights, exchange deadline, parking arrangements and applicable warranty.

Check:

  • Whether the reservation fee is refundable
  • What administration costs can be deducted
  • How long the price is protected
  • The deadline for exchanging contracts
  • What happens if your mortgage is declined
  • What happens if the developer changes the property
  • Whether agreed incentives are recorded
  • Which consumer code protects the purchase

Under the New Homes Quality Code applying to homes reserved from 2 March 2026 with registered developers, customers should receive a 14-day cooling-off period. The exchange deadline should generally be at least six weeks after reservation unless the buyer asks for an earlier date.

Other developers may operate under a different consumer code, so confirm the exact rules before paying.


8. Arrange the Mortgage Early

Some mortgage lenders apply different deposit, valuation or lending criteria to new build houses and flats. The lender will also need to know about developer incentives.

Tell your mortgage adviser about:

  • Cashback or deposit contributions
  • Free upgrades or paid legal costs
  • The property’s construction method
  • Whether it is a house, flat or conversion
  • Service charges and estate charges
  • The estimated completion date

If you are buying off-plan, the mortgage offer may expire before the property is ready. Ask whether the lender offers new build extensions and whether a new valuation or affordability assessment would be required.

Do not exchange contracts until your lender is satisfied with the property and your conveyancer confirms the funding arrangements.


9. Understand the Completion Date

A completed property may have a fixed completion date. An off-plan contract usually provides an estimated window, followed by formal notice when the property is ready.

Ask your conveyancer to explain:

  • The estimated completion window
  • How much notice you will receive
  • Whether the date can move forward
  • What happens if the property is delayed
  • Whether the contract includes a long-stop date
  • Your right to withdraw after serious delay

A long-stop date is an important final deadline. Depending on the contract, it may allow the buyer to end the purchase if the developer does not complete the home within the permitted period.

Avoid committing too early: Do not give notice on rented accommodation, book non-refundable removals or order made-to-measure furniture using only an estimated build date.


11. Check the Ownership and Ongoing Restrictions

A new build house may be freehold, while a flat is commonly leasehold in England and Wales. Shared ownership homes are leasehold even where the property is a house.

Restrictions may control:

  • Extensions and structural alterations
  • Changing the external appearance
  • Parking commercial vehicles or caravans
  • Keeping certain animals
  • Running a business from the property
  • Installing satellite dishes or solar panels
  • Letting the property
  • Changing fences or front gardens

Restrictions are not always unusual, but buyers should understand whether they conflict with future plans for the home.


12. Confirm the Warranty and Consumer Protection

Many new build homes include a ten-year structural warranty, but the precise cover depends on the warranty provider and policy.

For example, NHBC Buildmark generally includes a builder warranty period during the first two years, followed by insurance cover for specified structural problems during the remaining period. Other warranties may have different terms.

Check:

  • The name of the warranty provider
  • When the policy starts and ends
  • Which areas and structures are covered
  • What is excluded
  • Any minimum claim value or excess
  • How defects must be reported
  • Whether the lender accepts the warranty
  • Whether external areas, garages and retaining walls are included

A structural warranty is not the same as a full property survey, snagging inspection or guarantee that every defect will be repaired.


13. Check the Construction Method

New homes may use traditional masonry, timber frames, light steel frames, structural insulated panels or modular construction.

A modern construction system is not automatically a concern, but buyers should confirm:

  • The exact construction method
  • Whether it has recognised certification
  • Acceptance by the mortgage lender
  • Availability of buildings insurance
  • Maintenance requirements
  • Restrictions on drilling, extensions or alterations
  • Whether specialist repairs may be required

Ask for the construction details before exchange, particularly if the property is modular, panelised or converted from another type of building.


14. Arrange a Pre-Completion Inspection

Snagging means identifying defects, damage, incomplete work or poor finishes in a new home. Typical snags include damaged units, badly fitted doors, missing sealant, uneven decoration and faulty fittings.

More serious problems can involve drainage, ventilation, insulation, roof work, windows, heating or external levels.

Buyers protected by the New Homes Quality Code should be given the opportunity to inspect the property before completion or appoint a suitably qualified inspector.

During the inspection, check:

  • Doors, windows and locks
  • Walls, ceilings, floors and decoration
  • Kitchen units and appliances
  • Bathrooms, taps and drainage
  • Heating, ventilation and controls
  • Electrical sockets and lighting
  • Loft insulation and visible roof areas
  • Gardens, fences and external drainage
  • Parking spaces, garages and access
  • Items included in the specification

Important difference: A pre-completion inspection normally checks whether the finished home meets the expected standard. It is not necessarily a full structural survey or technical investigation.

Record defects with dated photographs and send the list in writing. Ask which items will be corrected before completion and when the remaining work will be finished.


15. Prepare for Completion and Aftercare

Before collecting the keys, confirm that your conveyancer has received the required completion and warranty documents.

Request a handover pack containing:

  • Warranty policy and certificates
  • Energy Performance Certificate
  • Appliance instructions and guarantees
  • Heating and ventilation guidance
  • Utility and meter information
  • Emergency contact details
  • After-sales and complaints procedure
  • Paint, flooring and product specifications
  • Management-company contact details
  • Waste collection and parking information

Take meter readings and photographs on completion day. Test the heating, hot water, appliances, windows, locks, alarms and electrical fittings as soon as possible.

New homes can experience minor drying and settlement as construction materials lose moisture. Report concerns promptly rather than assuming every crack or defect is normal settlement.


New Build Red Flags

  • Pressure to reserve immediately
  • Verbal promises that will not be confirmed in writing
  • No clear warranty information
  • Unexplained service or estate charges
  • Major differences between the show home and specification
  • No clear completion window or long-stop date
  • Refusal to explain future development phases
  • Unclear parking, garden or boundary ownership
  • Pressure to use the developer’s recommended professionals
  • Limited opportunity to inspect before completion
  • Repeated complaints about unresolved defects
