NHBC sign-off is one of the most consequential milestones on a new build residential development. Without it, plots can’t complete, sales can’t exchange, and the revenue that funds the next phase of the programme doesn’t flow. For a developer managing a large scheme across multiple phases, the cumulative impact of delayed NHBC sign-off — even by a few days per plot — can be significant.
Most of the factors that determine whether NHBC inspections pass first time sit with the specialist subcontractors on site. The quality of the groundworks. The standard of the roofing installation. The documentation produced at each stage. When those subcontractors are working to inconsistent standards, or producing documentation that doesn’t meet the required format, the risk of delays at inspection increases — and that risk sits with the developer.
What NHBC Inspectors Are Looking For
NHBC inspectors aren’t just checking that the work looks right. They’re checking that it was done in accordance with the relevant technical standards, that the materials used were specified correctly, and that the documentation supports what’s been claimed. On the roofing package specifically, that means felt and batten specification, fixing schedules, ventilation provision, and cold bridging details — all of which need to be demonstrably compliant, not just visually acceptable.
For groundworks, NHBC compliance involves formation sign-offs, sub-base compaction records, and drainage installation that meets the relevant standards. These aren’t paper exercises — they’re evidence that the work was done correctly, and they need to be in place before the inspection takes place, not assembled afterwards.
The Risk of Inconsistent Subcontractor Standards
The most common source of NHBC inspection delays isn’t poor workmanship — it’s incomplete or inconsistent documentation. A roofing subcontractor who hasn’t maintained plot-by-plot records. A groundworks contractor whose compaction test records don’t cover every area inspected. A scaffold that hasn’t been formally handed over with a signed certificate, creating uncertainty about whether the access arrangements for the roofing gang were compliant.
When specialist subcontractors are procured separately, with different management structures and different documentation standards, those gaps are difficult to identify in advance and expensive to resolve after the fact. The developer ends up managing the documentation shortfall as well as the construction programme.
How the Globe Group Addresses This
Across Globe Civil Engineering, Globe Cambridge, and Globe Roofing, the documentation produced at each stage of a project follows a consistent standard maintained at group level. GCE’s formation sign-offs and compaction records are produced as a standard part of the groundworks package. Globe Cambridge’s signed scaffold handover certificates and seven-day inspection records are issued as a matter of course, not on request. Globe Roofing’s plot completion records are aligned to NHBC requirements at the relevant mid-build stages.
This means that when an NHBC inspector arrives on a Globe Group site, the documentation exists, it’s in a consistent format, and it covers what’s needed. The developer isn’t chasing paperwork from three separate subcontractors in the days before an inspection.
Globe Roofing’s NHBC accreditation — alongside LABC and Premier warranty body recognition — reflects the division’s sustained compliance with the technical and documentation standards that warranty inspectors apply. That accreditation isn’t held once and forgotten; it requires ongoing demonstration of standards in practice.
Consistency Across Phases
On a phased residential development, consistency of subcontractor standards across phases is particularly important. If the groundworks contractor or roofing contractor changes between phases, the documentation formats change, the working methods change, and the standards need to be re-verified from scratch. NHBC inspectors who have established familiarity with a particular subcontractor’s documentation approach on earlier phases have to start again.
The Globe Group’s divisions work across phased developments as a standard part of their operating model. The same standards, the same documentation formats, and the same working methods apply on phase three as on phase one. Developers don’t have to re-procure and re-brief for each phase, and the NHBC sign-off process doesn’t have to be rebuilt from scratch each time.
