Employing a builder Electricians

Recent changes in the law mean that more work than ever has to be carried out by properly qualified electricians. They also have a new responsibility to carry out official checks on your electric system, and then give a certificate that confirms the work meets safety standards.

The work electricians can do varies from re-wiring a home from top to bottom, to adding a new socket or moving a light switch. They need to be able to read and implement wiring diagrams from architects and to create these themselves.

Electricians also need to be adept at chopping out plaster, drilling through walls, floors and ceilings and working out the best way to create electrical systems without too much visible wiring. They should come up with effective methods of hiding any wiring that can’t be chased into the wall, such as running wires behind skirting boards. Electricians may also install security or home automation systems.

Electrician qualifications

Electricians should hold an Electrotechnical Services NVQ/SVQ at Level 3 and be ‘Part P Registered,’ so they can legally approve electrical work. Some experienced electricians may have trained as an apprentice some time ago and won’t have the latest qualifications. In this case, they must make sure they have their current work assessed and, if necessary, re-train to continue working as an electrician.

Trade organisations for electricians

Check whether your electrician is a member of organisations such as the National Inspection Council for Electrical Installation Contracting (NICEIC) or the National Association of Professional Inspectors and Testers.

Both of these organisations are voluntary and members have to pay to join. But they do allow their members to issue certificates for all work carried out (even adding a plug or light switch) in accordance with national standards. Always check that your electrician’s membership hasn’t lapsed. Visit these organisations' websites for more information and lists of contractors.

Don’t forget to check your insurance policy to see if electrical or plumbing emergencies are covered. You must contact the insurance company first, not after you’ve called someone and incurred costs, as they often have their own tradespeople.
