Buying a new-build home: reservation, snagging and warranties

New-build homes in England: reservation fees, fast exchange deadlines, long-stop dates, snagging surveys, the usual 10-year warranty, and the 15-year Defective Premises Act limit.

In short

Buying a new-build home in England differs from buying a second-hand one: you may buy off-plan, pay a reservation fee that is refundable only in some cases, and be asked to exchange contracts soon after reserving (GOV.UK). GOV.UK says most new builds have a 10-year warranty for major structural problems and a 2-year warranty for general defects, which may not cover the whole property. Separately, the time limit to sue under the Defective Premises Act is 15 years for new claims (30 years for rights that arose before 28 June 2022). The statutory new homes ombudsman scheme in the Building Safety Act 2022 was not in force on legislation.gov.uk on 21 October 2026.

Money: reservation, deposit and charges

  • Reservation fee. It holds the property, but GOV.UK warns it “may only be refundable in certain circumstances”: read the small print before paying. The reservation rules of the New Homes Quality Code are in gazumping and gazundering.
  • Fast exchange. Many developers ask you to exchange and pay a deposit shortly after reserving. Tell your lender and conveyancer the deadline at once.
  • Recommended firms. Developers often have referral relationships with mortgage advisers and solicitors. GOV.UK says you are under no obligation to use them.
  • Extra charges. A new estate may carry estate facility charges for shared roads or green spaces. Your conveyancer should explain them before you sign.
  • New-build premium. GOV.UK notes that a new build may cost more than a similar second-hand home.

Timescales and the long-stop date

If the home is still being built, the developer gives an expected finish date, which can move. If it is delayed, your mortgage offer may need renewing, as offers last for a limited period. GOV.UK suggests writing a long-stop date into the contract, which lets you withdraw if the build is badly delayed. Ask what happens if the date is brought forward too.

Snagging

Snags are defects or unfinished work. GOV.UK suggests agreeing at exchange that a snagging survey will be done once the home is built and before completion. A professional or you yourself can do it; report the list to the developer and ask for repairs before you move in. Before making an offer, understand what will be fixed before completion and what happens if you have a dispute with the builder.

Ask the developer for the warranty document, check who provides it, and confirm what it excludes before you pay a deposit. GOV.UK also says to ask the developer for all material facts about the property before committing.

Leasehold, surveys and Scotland

GOV.UK says most flats are leasehold, and most new qualifying long leases cannot charge more than a peppercorn in ground rent since 30 June 2022: see leasehold and freehold and service charges and ground rent. In Scotland, a first-occupier new build does not need a Home Report, but an EPC is still required: see buying a home in Scotland.

Schemes for new builds

  • First Homes (England): new-build homes sold to first-time buyers at 30% to 50% off, capped at £250,000 after discount (£420,000 in London). Developer incentives must not exceed 5% of the discounted price.
  • Help to Buy - Wales: an equity loan of up to 20% on new builds up to £300,000.

See Help to Buy and First Homes.

What it costs

No official figure exists for reservation fees, snagging surveys or estate charges: they are set by the developer or the firm. Stamp Duty applies as for any purchase; test it with the stamp duty calculator.

Which professional to consult

A conveyancer checks the contract, the long-stop date, the warranty and the estate charges. A surveyor can carry out a snagging inspection. A mortgage adviser checks how long your mortgage offer lasts. See also home survey levels.
