| Concept | What it is | Primary sources |
|---|---|---|
| Buildmark | NHBC’s 10-year new-home warranty/insurance: insolvency/deposit cover pre-completion; ~2-year builder warranty (NHBC may step in); then ~8 years NHBC insurance for specified defects. | NHBC Buildmark (homeowners); Builder registration / FAQs |
| Road and Sewer Bonds | Discretionary NHBC surety for roads, sewers and open spaces in favour of LAs/utilities; A1 premium rating; bond limits from homes registered over last four calendar years; Buildmark registration of homes on site required. | NHBC Road and Sewer Bonds; Guidance notes PDF |
| Registration security / “NHBC bond” (broker usage) | NHBC Rules allow Conditions requiring security (bank/insurer bond, director/shareholder guarantees, etc.) against Buildmark and surety liabilities; brokers market third-party “NHBC bonds” as an alternative to cash security. Distinct from Road and Sewer Bonds. | NHBC Rules (from 23 Dec 2024) (Rules 5, 29); e.g. Nationwide Sureties NHBC Bond |
| Company “performance bonds / financial guarantees” | Statutory-account contingent-liability / off-balance headings that typically bundle road/sewer, section 106, JV and other sureties—rarely broken out as NHBC-only. | Individual company ARs below |
Distinction: Building-safety / cladding / Self-Remediation Term provisions (on-balance remediation estimates) are not NHBC Buildmark warranty bonds.
