If your organisation is already ISO 9001, 14001, 45001 or 27001 certified, you have the standards already — Robert connects to your existing access. UK statutory requirements (GDPR, Companies Act, IR35, CIS, Bribery Act) are free from gov.uk and HMRC.
No additional licence required. All free libraries above are included with every OpsWork tier — Foundation, Standard, and Enterprise. Updates tracked automatically when publishers issue new versions.
Connected to your subscriptions
Most UK HV consultancies already hold BSI, IEC and NEC4 subscriptions. Robert connects to them during implementation so your engineers stop searching PDFs and start searching standards.
BS, BS EN, ISO and IEC adopted standards
BS 7671 — IET Wiring Regulations
BS EN 50522 — Earthing of HV installations
BS EN 60076 — Transformer ratings
BS EN 62271-200 — AC switchgear above 1kV
BS EN 62305 — Lightning protection
BS EN 61140 — Protection against electric shock
BS EN 60099-4 — Surge arresters
BS EN 60044-1 — Current transformers
BS EN 60898-1 — Circuit breakers
BS EN 61936-1 — Power installations above 1kV AC
Robert reads the BS and BS EN standards your BSI Knowledge licence covers. ISO management standards are covered separately above.
International Electrotechnical Commission publications
IEC 60287 — Cable current rating
IEC 60228 — Conductors of insulated cables
IEC 60502 — Power cables 1–30kV
IEC 60076 — Power transformers
IEC 60909 — Short-circuit currents
IEC 62271 — High-voltage switchgear
IEC 60044 — Instrument transformers
IEC 61936 — Power installations above 1kV
IEC standards are typically included in BSI Knowledge subscriptions in the UK.
NEC Digital Professional licence
NEC4 ECC — Engineering and Construction Contract
NEC4 ECS — Engineering and Construction Subcontract
NEC4 PSC — Professional Service Contract
NEC4 TSC — Term Service Contract
All Options A–F including compensation events and early warnings
Secondary Options X1–X29 and Y(UK) clauses
Connected to your NEC Digital Professional licence. James and Michael reference clauses by number during NEC4 obligations and Application for Payment workflows.
Your framework-licensed documents
DNO technical documents are licensed to framework contractors. If your organisation holds the rights, Robert indexes them inside your own tenant — searchable like the public standards, but only by your engineers, only inside your data boundary.
DNO frameworks supported during implementation:
Most customers index 80–150 DNO documents during implementation.
Annual subscription costs sit outside OpsWork pricing. Most UK HV consultancies already hold BSI Knowledge, IEC and NEC4 Digital subscriptions as a routine cost of business. We map your existing access during implementation. If you don't currently subscribe, we help you procure at standard supplier rates — no mark-up.
How engineers use it
Your engineers type the question they need answered. Robert searches across every library — free and licensed — finds the relevant clauses, and returns the answer with source references attached.
"cable sizing 132kV XLPE burial depth"
IEC 60287 + ENA TS 09-12
"earth fault clearance time 33kV substation"
BS EN 50522 clause 5.3.2
"G99 application limits for 5MW solar farm"
ENA G99 Type B
"NEC4 compensation event timebar"
NEC4 ECC clause 61.3
"NERS Section 13 competency evidence checklist"
NERS v10 Section 13.4
"33kV switchgear arc flash IP rating"
IEC 62271-200
Every answer cites the source document, clause and version. Engineers approve all design outputs.
