Confirm they will handle that. - Prefer an electrician registered with a government-approved competent-person scheme (NICEIC, NAPIT or ELECSA) so they can self-certify the work meets the wiring regulations. - Insist on the Electrical Installation Certificate (or Minor Works Certificate) when the job is done. It is your proof the work is safe and compliant, and you will need it if you ever sell. - Look for consistent reviews across several named sources, not one polished profile. - Check any credential evidence, and that the business details independently check out. ## Contact - Phone: 01923 840629 - Website: http://www.jbelectricalcontractorsltd.co.uk --- Source: MyTrustedTraders, https://mytrustedtraders.com/traders/j-b-electrical-contractors-limited-2 Real public evidence only: every figure traces to a named source, with evidence held from 2 named public sources.
