Commissioning & Testing in United Kingdom
End-to-end acceptance testing, documented results and a handover pack that stands up to audit. delivered in United Kingdom by engineers who work to the standards, safety regime and documentation expectations of this market. Mobilisation from London in 6 hours. London's Slough and Docklands clusters plus Manchester and Edinburgh give a mature colocation market. The distinctive constraint is the CDM regime: as soon as work is construction, principal-contractor duties and written method statements apply, and operators audit for them.

The United Kingdom market
London's Slough and Docklands clusters plus Manchester and Edinburgh give a mature colocation market. The distinctive constraint is the CDM regime: as soon as work is construction, principal-contractor duties and written method statements apply, and operators audit for them.
We mobilise from London and Manchester with a target of 6 hours to site. London and Manchester hubs give six-hour mobilisation across England and Wales. Change advisory boards usually sit weekly, so submit early.

How we deliver commissioning & testing here
Commissioning in United Kingdom produces the evidence pack that closes the project: IEC 61935-1 certification, fibre to IEC 61280-4-2 with OTDR traces. Reports written for UK operator sign-off. Every test is traceable to a link, an outlet or a rack, because an aggregate pass rate is not something an auditor can use.
- Test plan agreed in advance, naming the standard, the limits and the pass criteria
- Copper and fibre certification on 100% of links, with failures re-terminated and re-tested
- Native test files delivered alongside the human-readable report, so results can be re-verified independently
- Power-on and functional checks recorded per rack, including failover where it is in scope
- Punch list closed out and re-tested before the handover is signed
Standards and compliance in United Kingdom
Work is signed off against the standards that actually apply here, not the ones our engineers are most familiar with. In United Kingdom that means BS EN 50173 and BS EN 50174 as the primary reference, with iec 61935-1 certification as the test regime.
Site safety runs under CDM Regulations 2015 — principal contractor duties, RAMS, written method statements. We supply certificates before mobilisation rather than on request.
Standards applied on site
- BS EN 50173 and BS EN 50174 for cabling
- BS EN 50600 for facility design and operations
- BS 7671 (IET Wiring Regulations) for electrical installation
- TIA-942 where a US-headquartered customer imposes it
- UK GDPR and the Data Protection Act 2018, supervised by the ICO
- NIS Regulations 2018 for operators of essential services
- FCA operational resilience rules for financial-services tenants
Site access and safety
Photo ID, signed NDA and often a basic DBS check for sites with public-sector tenants. Slough and Docklands facilities typically need 24–48 hours notice for escorted access.
- CDM Regulations 2015 — principal contractor duties, RAMS, written method statements
- CSCS or ECS cards for site personnel
- Permit-to-work and lockout/tagout on live distribution

Local questions
Working in United Kingdom
Do you produce RAMS for CDM compliance?
Yes. Every UK job ships with risk assessments and a written method statement, and we will work as principal contractor or as a contractor under your principal contractor, whichever the project structure requires.
Are your engineers CSCS or ECS carded?
Engineers working on construction-classified sites hold the appropriate ECS card. We provide card details in advance for site registration.
Can you support FCA operational resilience requirements?
We can supply the change records, test evidence and handover documentation that a financial-services tenant needs for its important business services evidence. We do not provide compliance advice.
