Ensure a smooth process and avoid costly delays! PS PJ Singh Co-Founder, Conveyancer Plus | Conveyancing Industry Expert Tuesday, 19 May 2026 12 min read - Buying a new build home involves strict deadlines, developer-favorable contracts, and significant legal risks. - Early instruction of experienced solicitors and thorough pre-completion checks are essential for a smooth purchase. - Staying engaged throughout the process helps buyers avoid costly delays and secures their legal ownership effectively. Buying a new build home feels exciting right up until the legal paperwork arrives. Unlike purchasing an older property, new build conveyancing brings a distinct set of pressures: developer-imposed deadlines, lengthy contracts written heavily in the builder's favour, and financial risks that can catch even experienced buyers off guard. A clear, well-structured new build conveyancing checklist is not optional. It is the difference between a smooth purchase and a costly, stressful delay. This guide walks you through every stage of the conveyancing process for new builds, from instructing a solicitor before you reserve, right through to post-completion protection. ## Table of Contents ## Key takeaways Point Details Instruct early, instruct wisely Appoint a solicitor who specialises in new builds before you pay your reservation fee. Disclose developer incentives All developer incentives must be declared to your mortgage lender to avoid offer withdrawal. Know your timeline Completed new builds typically take 8 to 14 weeks; off-plan purchases can run well beyond a year. Snag before you sign off Carry out a thorough pre-completion inspection and document every defect before accepting handover. Register promptly after completion Title registration must be completed quickly to protect your legal ownership after moving in. ## Preparation stage: choosing the right solicitor The single biggest mistake buyers make is treating solicitor selection as an afterthought. With new builds, your solicitor needs to be in place before you pay the reservation fee. Developers move quickly, and [exchange deadlines as tight as 28 days](https://www.mondaq.co.uk/uk/conveyancing/1741894/new-build-conveyancing-your-guide-to-buying-a-new-build-home) are common. If your solicitor is still getting up to speed when the clock is already ticking, you are starting at a serious disadvantage. Not every conveyancer has new build experience. Solicitors who primarily handle resale properties may not be familiar with developer contract structures, longstop dates, or how to handle phased developments. Ask directly whether the firm has handled new build purchases recently and how many per year. Before instructing anyone, compare quotes carefully. [Legal fees for new build conveyancing](/blog/solicitors-fees-your-guide-to-affordable-conveyancing) typically range between £1,300 and £2,200, which reflects the additional complexity compared to a standard resale. Do not choose solely on price. A cheap solicitor who misses a critical contract clause can cost you far more than any saving on legal fees. Check that your chosen solicitor is on your mortgage lender's approved panel. If they are not, your lender will appoint their own solicitor to act for them and you will pay two sets of fees. It is a simple check that saves an unnecessary expense. When you receive the reservation agreement, read it carefully with your solicitor. The reservation fee is usually non-refundable if you pull out, though it is typically deducted from the purchase price at exchange. Understanding exactly what you are committing to at this early stage prevents unpleasant surprises later. **Pro Tip:** _Ask your solicitor whether they have acted for buyers on developments by the same house builder before. Familiarity with a specific developer's contract style can cut days off the review process._ ## Steps from instruction to contract exchange Once your solicitor is instructed, the core legal work begins. The timeline you face depends significantly on whether you are buying a completed property or purchasing off-plan. [Completed new builds typically take 8 to 14 weeks](https://www.new-builds.co.uk/blog/new-build-conveyancing-guide-uk) to exchange, while off-plan purchases can take anywhere from 14 to 26 months or more, depending on the build programme. Here is how the process unfolds from instruction through to exchange: 1\. **Receive and review the developer's contract pack.** New build contracts are substantially longer than resale contracts. They typically run to 15 to 30 pages and contain terms heavily weighted in the developer's favour. Your solicitor will scrutinise every clause, including obligations around completion timelines, transfer of the freehold or leasehold, and any restrictions on the property. 2\. **Raise enquiries with the developer's solicitors.** Your solicitor will raise formal written questions covering anything unclear or concerning in the contract. This can take several rounds of correspondence, particularly if the development is still under construction. 3\. **Order and review property searches.** [Essential searches for new builds](https://www.new-builds.co.uk/blog/legal-checklist-exchanging-new-build) include local authority, environmental, drainage, flood risk, and chancel repair searches. New builds on former industrial land or near flood plains require particular attention to environmental results. 4\. **Check the title and developer's ownership.** Your solicitor will confirm the developer holds good title to the land and that there are no restrictive covenants or encumbrances that could affect your use of the property. For leasehold new builds, the complexity of the lease terms, including ground rent provisions and service charge structures, demands thorough review. 5\. **Confirm your mortgage offer is in place.** Your solicitor will check that all mortgage conditions are satisfied and that the offer is valid for the expected completion date. For off-plan purchases, mortgage offers often expire before construction finishes, requiring renewal. 6\. **Declare all developer incentives to your lender.** If the developer is offering cashback, part-exchange contributions, or upgraded fixtures as part of your deal, these must be formally disclosed to your mortgage lender. Failing to do so can result in your offer being withdrawn, sometimes at the last moment. 7\. **Negotiate the longstop date.** This is the contractual deadline by which the property must be completed. If the build overruns beyond this date, you may have the right to withdraw and recover your deposit. Longstop dates should be negotiated to give you realistic protection against delays. 8\. **Exchange contracts and pay your deposit.** The deposit is generally 10% of the purchase price, less any reservation fee already paid. Once exchanged, you are legally committed to buying. **Pro Tip:** _If the developer is pressing hard for exchange and your searches are still outstanding, do not be rushed. Exchanging with incomplete searches removes your legal protection. A good solicitor will push back on unrealistic timelines on your behalf._ ## Pre-completion checks before you move in The period between exchange and completion on a new build is when many buyers switch off. That is a mistake. There is still significant work to do before you collect the keys. - **Carry out a pre-completion snagging inspection.** Arrange this before your legal completion date, not after. A thorough [pre-completion walkthrough with a snagging checklist](https://www.blogarama.com/home-and-garden-blogs/1412727-samjades-construction-nig-ltd-blog/75781358-moving-into-dream-home-why-post-walkthrough-checklist-must) should cover every room, every fitting, and every external area. Bring a torch to check corners, under-stair areas, and cupboards. Builders typically address repairs within 30 to 90 days of handover, but defects are far easier to resolve before you move in and agree to accept the property. - **Verify the building warranty is registered.** The most common warranty is provided by NHBC (the National House Building Council) under its Buildmark scheme, though other providers exist. Builders' warranties and Section 38 and 104 infrastructure agreements must be verified before completion. Without confirmed warranty registration, your mortgage lender may refuse to release funds. - **Confirm your buildings insurance.** Unlike resale purchases, you are typically responsible for insuring the property from the date of exchange on a new build, not completion. Check your contract carefully and arrange cover immediately after exchange. - **Review your final completion statement.** Your solicitor will send a completion statement showing the final balance due, including the outstanding purchase price, your solicitor's fees, disbursements, and [stamp duty](/stamp-duty-explained-all-you-need-to-know). Review every line. Transfer your completion funds to your solicitor in good time so the monies are cleared and ready on completion day. Before exchange Before completion Searches complete and reviewed Snagging inspection carried out Contract terms negotiated Warranty registration confirmed Mortgage offer in place and valid Completion funds transferred to solicitor Developer incentives disclosed Buildings insurance active Deposit funds ready Completion statement reviewed and approved ## Post-completion: warranty, snagging, and registration Completion day is not the end of your checklist. Several important steps must follow in the weeks after you move in. - **Walk through the property again immediately after receiving the keys.** Document any defects or damage with photographs and a written log. Report these to the developer in writing as soon as possible. Under the NHBC Buildmark warranty, the developer is responsible for fixing defects in the first two years. Years three to ten are covered for major structural defects. - **Chase your solicitor to register the title at HM Land Registry.** Registration does not happen automatically on completion day. Your solicitor must submit the application, and delays are not uncommon given current Land Registry processing times. Until registration is complete, you are not the legal registered owner of record, even though you own the property in law. Monitor progress and confirm when registration is finalised. - **Keep all documentation in one safe place.** Store your title deeds, warranty certificates, infrastructure agreements, planning permission documents, and any correspondence with the developer. You will need these if you ever sell, remortgage, or make a warranty claim. - **Understand your service charge and management company obligations.** If you are buying a leasehold flat or a property on a managed estate, you will have ongoing financial obligations. Understand the service charge budget, how it is calculated, and who manages the building. **Pro Tip:** _Set a calendar reminder for the end of the developer's two-year defect period. This is your last opportunity to report snagging items that remain outstanding under the warranty before responsibility shifts._ ## My honest assessment of new build conveyancing I have worked with enough new build buyers to know that the cases that go smoothly almost always share one thing in common: the buyer engaged an experienced solicitor early and stayed genuinely involved throughout the process. What I have seen far too often is buyers who instruct whoever the developer recommends, often a solicitor who acts for the developer's other buyers in bulk and has little incentive to push back hard on contract terms. That is not to say those solicitors are incompetent. But there is an inherent tension in that arrangement that buyers rarely appreciate until a problem surfaces. The tight exchange deadlines concern me most. When developers impose 28-day windows, inexperienced buyers panic and exchange before their solicitor has had time to raise and resolve all enquiries. I have seen buyers lose deposits and miss critical contractual protections because of that pressure. [Leasehold complications](https://todaysconveyancer.co.uk/leasehold-complications-lengthening-transaction-times-as-agents-blame-conveyancing/) add another layer of difficulty, and they are showing up more frequently in new build transactions. My practical advice is this: treat your new build conveyancing checklist as a live document. Review it regularly, communicate proactively with your solicitor, and never feel embarrassed to ask what stage you are at and what needs to happen next. The buyers who stay engaged are the ones who complete on time and with their financial position intact. ## Get your new build conveyancing quote today Buying a new build is one of the most time-sensitive property purchases you can make, which means the quality of your legal representation genuinely matters.

Conveyancing for a completed new build typically takes 8 to 14 weeks. For off-plan purchases, the process can extend to 14 to 26 months or longer, depending on when construction finishes. ### What searches are needed for a new build property? The standard searches include local authority, environmental, drainage, flood risk, and chancel repair searches. These are particularly important for new builds on former industrial land or in areas at risk of flooding. ### Can I use any solicitor for a new build purchase? You can, but your chosen solicitor must be on your mortgage lender's approved panel. Using a solicitor without new build experience increases the risk of missing developer-favourable contract terms or failing to meet tight exchange deadlines. ### Do I need to declare developer incentives to my mortgage lender? Yes. All incentives, including cashback, upgraded fixtures, or part-exchange arrangements, must be formally disclosed to your lender. Failure to do so can result in your mortgage offer being withdrawn. ### What is a longstop date in a new build contract? A longstop date is the final contractual deadline by which the developer must complete the property. If the build overruns past this date, you generally have the right to withdraw and recover your deposit.
