Electrical contracting is one of the most credential-dense trades a commercial buyer deals with — and for good reason. The work is invisible when done well, dangerous when done badly, and central to a building's compliance evidence. Knowing what to look for turns a wall of logos into a usable checklist.
Competent person and certification schemes
The UK electrical industry operates recognised certification and competent person schemes under which contracting businesses are assessed and periodically re-assessed. Depending on the work, buyers may look for membership of such a scheme as a baseline signal — it indicates the business has been externally assessed against the relevant technical standards rather than self-declaring competence. Which scheme, and which scope of registration, should be matched to the actual work: installation, inspection and testing, and specialist areas such as EV charge point installation carry different requirements.
Qualifications behind the business
Beyond the business-level badge, the individuals doing the work carry their own qualifications — current wiring regulations qualifications, inspection and testing qualifications for those signing certification, and trade competence built through recognised routes. A serious contractor answers 'who exactly will be doing and certifying this work, and what are they qualified in?' without hesitation.
Certification as a deliverable
Commercial electrical work should produce paper: electrical installation certificates or minor works certificates for new work, and condition reports (EICRs) for periodic inspection. When vetting, ask for sanitised examples from recent commercial jobs. Clean, complete certification habits are one of the strongest predictors of a contractor you can build compliance records on — and sloppy paperwork on the sales call never improves after appointment.
Commercial experience specifically
Domestic and commercial electrical work differ in scale, systems and context: three-phase distribution, emergency lighting, containment, landlord supplies, working in occupied buildings under permit conditions. Ask for examples of comparable commercial work — building types, project values, whether they have worked for managed property clients before. A strong domestic electrician is not automatically a strong commercial one.
The rest of the standard vet
Everything in the general vetting process still applies: insurance at appropriate levels, health and safety documentation, references and business standing. Electrical credentials sit on top of that baseline, not instead of it.

Frequently asked questions
- Is scheme membership legally required for commercial electrical work?
- Requirements differ by work type and setting, and the detail sits outside a short answer — but scheme membership is a widely used competence signal in commercial procurement, and duty holders are expected to appoint competent persons. Match the registration scope to the actual work and take advice where unsure.
- What certification should I receive after electrical work?
- New installation work should produce an electrical installation certificate or minor works certificate as appropriate; periodic inspection produces an EICR. File them against the building — they are part of its compliance record.
