We complement your taste with state of the art installation practice that is pleasing to the eye and energy efficient for your budget and friendly to the planet.   

Upgrade / replacement of Consumer Units:

Consumer unit, also known as a fuse box or distribution board, is responsible for controlling and distributing electricity throughout the building. It incorporates protective devices to protect the overall system from overload, short circuits, and electrical faults. Upgrading the consumer unit is crucial for ensuring electrical safety of a property and bringing it up to date with current standards. Often, Consumer Unit upgrade is the single most important thing that can be done to improve the safety of an electrical installation, short of a full rewire. During a consumer unit upgrade, we will assess the electrical wiring and equipment in the property to identify any potential risks or outdated components. We will install a new consumer unit that meets the latest safety regulations and is capable of handling the electrical demands of modern appliances and technologies. Upgrading the consumer unit offers increased electrical capacity, better protection against electrical faults, improved safety features, and the ability to incorporate additional circuits and protective devices. It also helps to minimize the risk of electric shocks, electrical fires, and other electrical hazards. In the UK, consumer units and protective devices must comply with British standards and regulations, including the BS 7671 Wiring Regulations. These regulations outline specific requirements and guidelines for their installation, operation, and safety to ensure the utmost protection for consumers. Our experience and expertise in this regard plays a vital role in achieving safety and quality.

Consumer units: Metal or plastic

Metal consumer units offer better protection against fire hazards and can provide enhanced electromagnetic shielding. They are generally more durable and resistant to physical damage. Additionally, metal consumer units often have more space for electrical components and can be more secure. The requirements for non-combustible consumer units were introduced in the 17th Edition of the IET Wiring Regulations (BS 7471:2008+A3:2015). Regulation 421.1.20 of BS 7671:2018 states, for consumer units and similar switchgear assemblies in domestic premises, to be manufactured from non-combustible materials or be enclosed in a cabinet constructed from non-combustible materials.

Consumer units and protective devices:

The importance of consumer units lies in their ability to prevent electrical fires and electrocution hazards. They are equipped with protective devices such as circuit breakers, residual current devices (RCDs), and fuses that serve as safeguards against potential dangers. Circuit breakers automatically trip and interrupt the flow of electricity when an overload or short circuit occurs. RCDs detect any leakage current and rapidly disconnect the power supply, preventing fatal electric shocks. Fuses, on the other hand, act as sacrificial components that melt or blow when excessive current passes through, thereby protecting the wiring and connected equipment and preventing further damage. Electrical systems and safety measures can vary depending on multiple factors, including national and local standards, building codes, and specific circumstances which may require use of following protective devices:

RCD (Residual Current Device): An RCD is a life-saving device that quickly detects any imbalance in electrical currents and trips the circuit to prevent electric shocks and fire risks. It provides extra protection by monitoring the flow of electricity and cutting off the power supply if an imbalance occurs. Amendment 2 of the 18th Edition Wiring Regulations (BS 7671) came into full effect on 28 September 2022 required Type A RCDs as opposed to Type AC RCDs previously. Type A RCDs are considered to provide a higher level of sensitivity in detecting earth leakage currents and offer a broad spectrum of protection. On the other hand, a Type AC RCD provides protection for alternating currents (AC) only. In conclusion, while Type A RCDs provide protection against both alternating and pulsating direct currents, Type AC RCDs offer protection against alternating currents only.

RCBO (Residual Current Breaker with Overcurrent): Combining the features of an RCD and an MCB (Miniature Circuit Breaker), an RCBO protects against both electric shocks and overcurrent situations. It provides the advantage of selective disconnection, allowing only the faulty circuit to trip while others remain functional.

SPD (Surge Protection Device): SPDs help protect electrical equipment from power surges and voltage spikes caused by lightning strikes, utility grid switching, or other electrical disturbances. They divert excess voltage to the ground, safeguarding sensitive devices such as computers, TVs, and other electronics from damage. Consumer units installed after 28 September 2022 are likely to incorporate SPDs (Surge Protective Device).

AFDD (Arc Fault Detection Device): Designed to detect dangerous electrical arcs caused by loose connections, damaged cables, or faulty devices, an AFDD offers an additional layer of safety. It can identify potential fire risks and automatically disconnect the power supply, reducing the likelihood of fires breaking out.
