A sticking window, uneven flooring or a leaking roof can quickly turn the excitement of a new home into a dispute. So, who pays for defects in a new-build home? In most cases, the developer is responsible for putting right defects caused by poor workmanship, incomplete work or failure to meet the agreed specification. The practical challenge is proving what is wrong, reporting it correctly and acting before the relevant deadlines expire.
For buyers across the Midlands and South Yorkshire, the answer is rarely as simple as sending an email and waiting for a repair. Responsibility can depend on the type of defect, when it was discovered, the terms of the warranty and whether the developer accepts liability. An independent, evidence-led inspection gives you a far stronger starting point.
Who pays for defects before legal completion?
Before legal completion, the developer remains responsible for the property and for completing it to the standard set out in the contract and relevant building requirements. If a pre-completion inspection identifies defects, incomplete finishes or apparent compliance concerns, these should be recorded and raised before you take ownership.
This is the strongest point at which to seek corrective work. You have not yet completed the purchase, and the developer has the clearest obligation to deliver the home as agreed. In practice, however, buyers may be under pressure from moving arrangements, mortgage deadlines or notices to complete. That pressure should not lead to defects being accepted without a clear written record.
A professional pre-completion inspection can identify issues such as poorly fitted doors, damaged brickwork, gaps around pipework, inadequate sealant, unfinished joinery, roof concerns and defects affecting drainage or ventilation. Not every item will delay completion, but the report establishes a dated record of the condition before you move in.
The developer’s responsibility after completion
After completion, the developer is normally your first point of contact for defects reported during the initial builder warranty or defects period. This is often the first two years, although exact arrangements vary between developers and warranty providers.
During this period, the developer would generally be expected to rectify defects resulting from workmanship, materials or incomplete construction. Typical examples include cracked tiles caused by poor installation, failed sealant, defective doors and windows, uneven finishes, leaking sanitaryware, poorly functioning heating controls and external works that do not perform as intended.
The developer is not automatically responsible for every problem that appears after you move in. Normal settlement, minor cosmetic changes and damage caused by the homeowner may fall outside their liability. Equally, an issue described as settlement should not simply be dismissed without scrutiny if it is excessive, affects performance or points to a wider construction problem.
Keep communications factual and in writing. Identify the location, explain the impact, include photographs where useful and ask for a proposed remedial timescale. A snagging report is particularly valuable because it groups defects into a clear, professional schedule rather than leaving you to argue about individual items during a site visit.
Why evidence changes the conversation
Developers manage many homes and many reported snags. A vague statement that something “does not look right” can be difficult to progress. Evidence makes the issue measurable and easier to assess.
A detailed inspection report can record dimensions, photographs, defect locations, likely causes and relevant standards or tolerances where applicable. It can distinguish between a superficial finish issue and a defect that may affect water ingress, safety, energy performance or long-term durability. This helps the developer plan repairs and gives the homeowner a defensible record if the matter is disputed or repeatedly delayed.
When does the structural warranty pay for defects?
Most new-build homes are sold with a structural warranty, often lasting 10 years. The first part of that cover commonly sits with the developer, while later years may provide insurance-backed protection for specific defects. The precise policy wording matters, so homeowners should check their own warranty documents rather than rely on a broad description from the sales office.
A structural warranty is not a general maintenance policy and does not usually cover every snag. It is more likely to be relevant where there is a significant defect to the structure, weatherproofing or another insured element of the home, subject to its terms, exclusions and minimum claim thresholds.
For example, a poorly painted wall or a scratched worktop would normally remain a developer snagging matter. By contrast, persistent water penetration linked to defective roof construction, serious movement or a failure in a covered structural element may require the warranty provider’s involvement if the developer does not resolve it or where the policy applies.
Do not wait until the end of the warranty to investigate a concern. Water ingress, roof defects and heat loss can develop gradually, while early symptoms may be mistaken for a minor snag. Thermal imaging, drone roof inspection and targeted condition surveys can provide the evidence needed to understand whether there is a local repair issue or a wider building-performance failure.
When might the homeowner have to pay?
Homeowners may become responsible where a defect is caused by accidental damage, alterations, lack of maintenance or work carried out by an unqualified third party. If you replace fittings, alter drainage, install a loft conversion or make changes that affect the original construction, responsibility can become more complicated.
You may also face costs if you allow a known issue to worsen. For instance, ignoring a small leak until it damages ceilings and finishes could lead to arguments about the extent of recoverable repair costs. Report concerns promptly and keep a record of each communication, appointment and attempted repair.
There is also a practical distinction between paying for a repair and paying for expert evidence. An independent inspection has a cost, but it can prevent much larger expense by identifying defects while the developer’s obligation is still live. It can also stop homeowners accepting a superficial repair when the underlying cause has not been addressed.
What if the developer refuses to repair defects?
A refusal is not necessarily the end of the matter. First, ask the developer to explain its position in writing and identify the basis on which it considers the item excluded, acceptable or caused by the homeowner. If a repair has been attempted but has failed, document the condition again rather than relying only on the original snagging list.
Your next route may depend on the developer’s complaints procedure, the new-home warranty scheme and the protections available under the New Homes Quality Code or other applicable consumer arrangements. Formal resolution processes have rules, time limits and evidence requirements. An organised inspection report, repair history and clear photographs can make a material difference.
For serious or unresolved matters, independent legal advice may be appropriate. This is particularly relevant where there is significant financial loss, a potential safety issue, repeated failure to remedy defects or a dispute over whether the problem is structural. The legal position can depend on the purchase contract, warranty policy, the nature of the claim and whether documents were executed as a contract or deed.
A practical approach to protecting your position
The most effective approach is to inspect early, report clearly and follow up consistently. A pre-completion snagging inspection provides a baseline before you move in. A post-completion inspection can identify defects that become clearer once the home is occupied and services are in use. Finally, a two-year warranty inspection helps ensure outstanding defects are documented before the builder’s initial responsibility period ends.
New Homes Inspections provides independent, evidence-led reports designed to help homeowners present defects clearly and pursue practical remedial action. The purpose is not to create conflict for its own sake. It is to establish what is wrong, assess the likely significance and give you the documentation needed to protect your investment.
If a defect has appeared, do not assume it is too small to matter or too late to report. Establish the facts while the evidence is visible, the repair route is open and responsibility can still be properly tested.
