The Snagging Crisis: Why Quality Assurance Is a Commercial Imperative, Not an Afterthought

Nearly every new home buyer in the UK encounters snags and defects after completion. The question is not whether snags and defects happen. It is who finds them, when, and what follows.

The Cost of Finding Out Too Late

The traditional model is reactive by design: quality inspections too close to practical completion, snagging lists compiled post-handover, defects reported by residents and logged for resolution. This model is expensive - not just in remedial cost, but in time, contractor relationships and resident trust.

For many buyers this is the largest financial commitment of their lives. When they arrive to find fifteen or more defects, the trust window is narrow. Post-completion remedial work means contractors returning to occupied homes, access coordination, formal complaints. The HBF's own conclusion is clear: to raise satisfaction further, contractors must reduce post-occupation defects and improve after-sales service.

What a “Customer Eye” Sees That a Site Team Doesn't

Site teams and main contractors provide excellent technical QA. But as projects approach practical completion, their frame of reference is necessarily delivery-focused. A customer arriving on day one sees the paint finish on the skirting board, the door that doesn't close cleanly, the shower that runs cold.

"The most damaging snags are rarely structural. They are the accumulation of small things that tell a resident their home was not properly finished before they arrived."

When Conductor CX embeds our QA service from the earliest stages - working alongside the main contractor, not after them - we add a perspective the delivery process cannot provide from within: the perspective of the person who is going to live there.

The Data

Across our projects, the pattern is consistent. Around 30% of snags are cosmetic; approximately 25% are MEP-related. Cosmetic defects are the most visible and the cheapest to resolve pre-handover. MEP faults - heating, ventilation, water pressure - are the ones that generate the most significant complaints, and are often only apparent under occupancy conditions.

Proactive, customer-led QA works. On schemes where we have embedded it alongside the main contractor, we have achieved:

• 90%+ reduction in snagging levels at handover
• zero onward cost to the developer and in many cases,
• 100% net resident satisfaction at handover

These are not marginal improvements. They are the result of resolving issues before residents arrive, not after.

The Commercial Case

Every defect that survives to completion is a future liability. Every defect resolved before handover is a cost avoided - a contractor who does not return, a complaint never logged, a resident whose first experience is positive.

"The question is not whether QA costs money. It is whether you pay for it before completion or after. The bill is always higher after."

For build-to-rent investors and operators, the stakes are clear: a poorly finished home drives early renewals risk, generates maintenance overhead and undermines occupancy performance. A well-finished home, delivered to a resident who moved in smoothly, is the foundation of a tenancy that renews.

The Bar Is Still Too Low

Satisfaction is rising and the New Homes Quality Code is raising the floor across the industry. But 93.7% of buyers still encountering defects is not a success story. It is a baseline the sector has normalised. Our Customer First Forum research found that only 40% of residential developers consider CX at the design or planning stage. Snagging is, in part, the consequence of that gap.

The decisions made at design and fit-out stage - before a site team ever walks a completed apartment - are where the snagging bill is written. Quality Assurance is not a cost of delivery. It is a driver of commercial performance. Developers and operators who treat it that way will not just build better homes. They will build better businesses.

Conductor CX delivers Quality Assurance as a standalone service and as part of an integrated customer care and experience programme.
