More about General Electrical Work


Commercial general electrical work is essential for keeping businesses safe, productive and legally compliant. From office fit-outs and shop lighting to data cabling and emergency systems, every workplace depends on reliable electrics. The Electricity at Work Regulations 1989 require businesses to maintain their electrical systems so as to prevent danger, and regular inspection and testing is the usual way to show that duty is being met.


Typical services for commercial sites include installing and maintaining three-phase supplies, upgrading distribution boards, adding RCD and surge protection, and routine testing recorded on an Electrical Installation Condition Report (EICR). Electrical Safety First recommends periodic inspection of business premises at least every five years, and the inspector may set a shorter interval for demanding environments. Many businesses also need lighting installations, including emergency lighting, and energy-saving upgrades such as LED office lighting and smart building controls.


Standards and certification


New work is designed and tested to BS 7671:2018+A4:2026, the current IET Wiring Regulations, and recorded on an Electrical Installation Certificate (EIC) or, for small additions to an existing circuit, a Minor Electrical Installation Works Certificate (MEIWC). Part P of the Building Regulations applies to homes in England rather than commercial premises, but mixed-use buildings with flats need care. On larger projects, electrical installation is construction work under the Construction (Design and Management) Regulations 2015, so planning and site safety duties apply.

FAQ

Need Help? RoboMo's Got Answers

What electrical services do commercial buildings typically need?
Commercial services include distribution board upgrades, lighting installation, socket circuits, data cabling, emergency lighting, RCD and surge protection, and EICR inspections.
Is PAT testing a legal requirement for businesses?
Not as a fixed annual test. The Electricity at Work Regulations 1989 require equipment to be maintained in a safe condition, and HSE says the frequency of checks depends on the type of equipment and where it is used. Many electricians offer PAT testing alongside general maintenance.
Do I need an EICR for my business?
There is no single law that names the EICR, but the Electricity at Work Regulations require you to maintain a safe installation, and an EICR is the recognised way to evidence it. Electrical Safety First recommends one at least every five years for business premises.
Can work be done outside business hours to avoid disruption?
Yes. Many commercial electricians offer evening or weekend appointments to avoid disrupting business operations.
What should I check before hiring a commercial electrician?
Ask the electrician which competent person scheme they are registered with and check that registration on the scheme's own website. Ask for details of their insurance, such as public liability cover, and check they suit your job. For new circuits or a new distribution board, you should receive an Electrical Installation Certificate (EIC) to BS 7671.
