Electrical Testing & Commissioning
Certified verification for new builds, refurbishments & upgrades
At Optima Electrical Services Ltd, we deliver full electrical testing, initial verification, and commissioning for new build, refurbishment, and major upgrade projects across the Midlands and South West. Our NICEIC-approved engineers ensure every installation is inspected, verified to BS 7671, function-tested and certified with an Electrical Installation Certificate (EIC) — giving contractors, developers and clients total confidence at handover.
Landlords
Ensure every property is ready for handover.
Initial verification and certification confirm that new or refurbished electrical installations meet safety standards before tenants move in.
Businesses and offices
Start operations with confidence.
Our commissioning process verifies that all electrical systems function safely, efficiently, and in full compliance with BS 7671.
Schools, care homes, and hotels
Safety and reliability from day one.
Thorough electrical testing ensures environments used by staff, students, and guests are fully certified and fit for use.
Initial verification is the formal inspection and testing applied to new or altered installations before energisation. It confirms the wiring and protection measures meet BS 7671. Commissioning follows to prove the system operates safely and as designed. Working with main contractors, M&E teams and consultants, we schedule works around your programme and provide clear, traceable documentation.

Frequently Asked Questions
Q1: What is initial verification?
Initial verification is the inspection and testing of a new or altered installation before it is energised, confirming compliance with BS 7671 and that protective measures are effective.
Q2: How is commissioning different from initial verification?
Initial verification proves the installation is safe to energise; commissioning confirms the system operates as designed (functional tests, controls, sequencing) and is ready for handover.
Q3: Do both new builds and refurbishments require initial verification?
Yes. Any new, extended or modified circuits must be initially verified and tested to BS 7671 before being placed into service.
Q4: What certification will I receive?
You’ll receive a complete Electrical Installation Certificate (EIC) with inspection schedules, test results and any variations, suitable for client, insurer and building control records.
Q5: Can you work alongside other contractors on tight programmes?
Absolutely. We coordinate with main contractors and M&E teams, plan outages, and can issue staged certificates on multi-phase sites.
Q6: How quickly can you issue certificates?
Most EICs are issued within 24–48 hours of completion. Larger projects may be certified in stages to match your programme.
