Business Electrical Installations, Repairs & Maintenance

All Barnes Electricians are licensed and trained to the highest standards. We provide fixed price quotes on all business electrical installations, repairs, maintenance and testing services. We can work as individual contractors or as sub-contractors on larger projects — in particular with our parent company Building Vision London where a multi-skilled team and additional trades are required.

Barnes Electricians provide everything from full electrical schematic design and installation for new business premises, to repairs, upgrades and rewiring for existing commercial premises. Typical services can include new commercial and indusctial lighting, heating, security systems, PAT testing, maintenance, and repairs.

All work is carried out with minimal disruption to your business. All electrical installation, addition or alteration work is carried out to BS7671 standards, to comply with the latest safety regulations, including Part ‘P’ of the Building Regulations, the Electricity Supply Regulations and the Electricity at Work Regulations.

A Compliance Certificate will be issued upon completion of the job, declaring it meets appropriate safety standards. This will either be an Electrical Installation Certificate (EIC) or a Minor Electrical Installation Works Certificate (MEIWC) which you should keep in a safe place.

Eco-friendly improved energy efficiency

Commercial Lighting Design & Installation

High-quality lighting will enhance the aesthetic appeal of any business environment for both customers and employees. Your lighting choices will also affect energy costs. We can provide commercial lighting design advice and solutions for improved energy efficiency and for all working environments, including shops & offices, hotels & restaurants, salons & clinics, warehouses & industrial premises.

Lighting can be used to add atmosphere and sophistication, or highlight unique architectural features and décor. We can install recessed lighting on ceilings almost anywhere, in shops, offices and entrance halls using energy efficient LED fittings, Halogen bulbs for a warm natural light, or efficient Compact Fluorescent Lamps (CFL) for reduced glare in offices.

We can also provide emergency lighting for any commercial situation, and energy efficient external landscape / security lighting to deter crime, including motion detectors, floodlights, occupancy sensors and tree lights to meet the unique needs of your business.

Barnes Electricians can provide advice and technical solutions such as emergency escape route lighting, standby lighting, outdoor security lights and electrical safety equipment to keep your business safe, and to ensure the safe evacuation of occupants in the event of an emergency.

For this reason, all emergency lighting in commercial buildings must be regularly checked, including ‘flick’ testing to ensure they are functioning correctly, and properly maintained, in order to comply with fire safety and building regulations. Fire safety systems should also be checked regularly.

In addition to installing the above safety and security systems, Barnes Electricians can also provide the regular maintenance required for all your important equipment; ensuring both Regulations compliance and peace of mind for business owners, employees and customers.

Commercial Electrical Wiring & Rewiring

Barnes Electricians provide a full wiring and rewiring service for all types of commercial premises. Most businesses use more electrical appliances today than we did 20+ years ago, so we can also advise on any wiring upgrades required to ensure your wiring is capable of handling resulting increases in electrical loads.

We also offer partial rewiring for major renovations such as new extensions and business premises conversions. Defined as ‘material alterations’, along with new wiring, improvements to wiring in existing premises may also be required to ensure it can safely carry additional loads.

Not only will your new wiring will require to be earthed and cross-bonded, but improvements to wiring in existing areas may also be required to ensure it can safely carry additional loads, and meets energy efficiency requirements to comply with Building Regulations.

We handle everything from initial survey and quotation, to the safe installation of your new wiring and fuse boards. We’ll ensure it complies with all relevant electrical regulations and safety standards. On completion we’ll provide the relevant certification for the installation.

Barnes Electricians offer a free survey and fixed price for full and partial rewires, so you’ll know the exact cost upfront and won’t be hit with any nasty surprises once the work is completed. If any additional work is required, we’ll always provide a quote first.

power backup generation minimises business disruption

Emergency Power & Surge Protection

    A commercial standby or backup generator connected to the main distribution board circuitry will power up automatically, to provide electricity within seconds of a power loss. Once power is restored, the generator automatically shuts off. The addition of a USB battery to the generator, eliminates the time lag, so power stays on during generated power transition, which may be essential to the preservation of business data.

    Power surges can completely destroy a company’s electrical devices and appliances, such as Computers, air conditioners, scanners, printers, TVs, security systems, refrigerators, alarm systems, microwaves and phone systems. Surges can be caused by both internal sources, such as faulty wiring, and external sources, such as lightning or fallen power lines.

    The circuit in a UPS monitors voltage continuously. It will switch to AC power as soon as it senses a surge, protecting your equipment from damage. If you don’t have UPS, we can also provide inexpensive surge protection to block excessive voltage spikes, protect valuable data, minimise business disruption, and save you having to replace expensive equipment.
