What housebuilder aftercare teams need to know about the New Homes Ombudsman Scheme before a complaint lands.
The New Homes Ombudsman Service (NHOS) came into force under the Building Safety Act 2022, and since then the pressure on housebuilder customer care teams has increased significantly. Homeowners now have a formal, independent route to escalate unresolved complaints — and decisions can require remedial work, compensation payments, and written apologies. For aftercare managers and site teams, that changes the stakes around how complaints are logged, responded to, and resolved on the ground.
This article is a practical guide for housebuilder customer care managers, site managers, and aftercare coordinators who need to understand what the scheme demands, where complaints most often go wrong, and how to build a process that resolves defects before they become formal cases. It draws on the operational realities of new build aftercare work across Yorkshire and is aimed squarely at professionals responsible for protecting both the homeowner relationship and the builder's reputation.
The NHOS operates under the New Homes Quality Code, which all registered housebuilders are required to follow. The Code sets out minimum standards for the sales process, construction quality, and — critically for aftercare teams — the complaints handling procedure. Before a homeowner can approach the Ombudsman, they must have gone through the builder's internal complaints process and either received a final response or waited more than 56 days without resolution.
What this means in practice is that the Ombudsman is not the first line of contact for most homeowners — but it is the destination if your internal process fails them. The NHOS can award up to £50,000 in compensation and can require builders to carry out specific remedial works. Decisions are binding on the builder, not the homeowner. If you are registered with the scheme and a complaint is upheld, you cannot appeal the outcome in the way you might challenge a court judgment.
The Code requires builders to acknowledge complaints within 5 calendar days and provide a substantive response within 30 calendar days. Aftercare teams should treat these as hard deadlines, not guidelines. Missing them is one of the most common reasons a complaint escalates to the Ombudsman unnecessarily.
Understanding where complaints cluster helps aftercare teams prioritise their processes. Based on NHOS case data and the experience of contractors working in new build aftercare in Leeds and across Yorkshire, the most frequent complaint categories fall into a predictable set:
The NHOS will look at your complaints handling procedure as part of any investigation. A process that exists only on paper — one where acknowledgements are sent but nothing happens, or where responses are templated without addressing the specific issue — will not serve you well. Ombudsman investigators are experienced at identifying whether a builder genuinely engaged with a complaint or simply went through the motions.
A defensible process has several non-negotiable elements. Complaints must be logged centrally with a unique reference. Acknowledgements must go out within the five-day window without exception. Every response must address the specific points raised, not provide a general statement about build quality standards. If a site inspection is required before a response can be given, that inspection must be booked promptly and the homeowner kept informed of the timeline.
Customer care managers should conduct regular audits of open complaints — not just to check response times, but to identify patterns. If the same defect type is recurring across multiple plots, that is a systemic issue, not individual bad luck, and it needs to be addressed at a process or specification level before the NHOS starts seeing a pattern too.
Most new build homes come with a ten-year structural warranty — typically from NHBC, Premier Guarantee, or a similar provider — but the first two years are the builder's direct responsibility. During this period, the developer must repair or replace defects that result from the builder not meeting the warranty provider's technical requirements. This is separate from the NHOS process but intersects with it constantly.
Where it gets complicated is the definition of a defect versus fair wear and tear versus a maintenance item. Builders sometimes push back on complaints by categorising issues as homeowner responsibility, and in some cases that is legitimate. But when this categorisation is applied too aggressively — or communicated poorly — it generates exactly the kind of dispute that ends up at the Ombudsman.
Aftercare teams working in new build aftercare across Yorkshire should ensure that any decision to decline a repair under the defects liability period is documented, explained clearly in writing to the homeowner, and includes reference to the relevant standard or warranty clause. Verbal refusals or vague written responses create unnecessary risk.
Many of the complaints that reach the Ombudsman are rooted in a mismatch of expectations that was set — or not set — at legal completion. If a homeowner is not told that some shrinkage cracking is normal in the first year, the first hairline crack becomes a crisis. If they are not shown how to bleed radiators or operate the MVHR system, a heating callback becomes a complaint about a defective boiler.
The handover appointment is not a box-ticking exercise. It is the single most important opportunity a builder has to shape a homeowner's understanding of what they have bought and what to expect in the months ahead. Customer care managers should invest in structured handover packs — written in plain English, not warranty provider boilerplate — that cover normal building behaviour, how to report a defect, response time commitments, and who to contact for what.
Homeowners who feel informed and respected are less likely to escalate. This is not about managing people into accepting poor quality — it is about giving them the context to interpret normal behaviour correctly and the confidence that genuine issues will be dealt with.
If a homeowner submits a case to the NHOS, the builder will be notified and asked to provide a case file — all relevant correspondence, inspection reports, contractor invoices, and a timeline of actions taken. This is where the quality of your record-keeping becomes critical. Builders who cannot produce a coherent paper trail are at an immediate disadvantage, even if they have done the right things on the ground.
The investigation process involves a case handler reviewing submissions from both sides. There is no formal hearing. The Ombudsman will assess whether the builder followed the New Homes Quality Code, whether the complaint was handled appropriately, and whether any remedial action required is proportionate to the defect identified. Outcomes can include a requirement to carry out specific works, a financial award, or both.
Builders should not assume that engaging a solicitor will improve their position in most cases. The NHOS process is designed to be accessible to consumers and straightforward in its standards. What does improve your position is a clear record of having taken the complaint seriously, responded within the required timescales, and made genuine attempts to resolve the issue.
Gebai Property Services Ltd provides new build aftercare services to housebuilders and developers across Leeds and Yorkshire. For customer care managers handling new homes ombudsman complaints, the quality and responsiveness of your maintenance contractor is directly relevant to your risk exposure. A defect that sits unresolved for weeks — because a contractor has not attended or has attended and not fixed the issue properly — is a defect that edges closer to an Ombudsman case.
We work as an extension of your aftercare team, attending plots within agreed SLAs, providing written inspection reports and photographic records that can form part of your complaints file, and completing repairs to a standard that closes the issue rather than creating a follow-up. For handling new build homeowner complaints under the New Homes Ombudsman Scheme, that paper trail and reliable attendance record is not a nice-to-have — it is the difference between a complaint resolved internally and one that goes to investigation.
Our work covers the full range of typical defects liability period repairs: plumbing, joinery, plastering, drainage, external works, heating system rectification, and fabric defects. We operate across new build sites in Leeds, Bradford, Wakefield, Sheffield, Harrogate, and the wider Yorkshire region. Where multiple trades are required, we coordinate directly rather than leaving that burden with your customer care team.
If you are a site manager or customer care manager looking for a more reliable aftercare contractor — or if you are restructuring your defects process ahead of NHOS registration — contact Gebai to discuss how we can support your programme.
