Your consumer unit (also referred to as fusebox/fuseboard) is the nerve centre of your electrical installation. It is responsible for distributing power to your circuits and equipment and most importantly, it monitors the performance and therefore controls the safety of the entire installation. The individual devices inside a consumer unit (MCBs RCDs, RCBOs, SPDs and AFDDs) all play different roles but are all focused on safety, disconnecting the supply under different circumstances and faults to protect you and your property from electric shock and fire. A fully compliant and fully functioning consumer unit is essential for every single home and business.
Unfortunately, just like the brakes on a car, you don't know until you need it and it doesn't perform. This is why just as a car needs an MOT, it is essential to have an EICR (Electrical Installation Condition Report) carried out at least every 5 years by a fully certified engineer. The consumer unit is one of the primary focuses of an EICR test. Click to learn more about EICR inspections
The cost very much depends on the individual circumstances and layout of your electrical system. Also, some properties will legally require a higher degree of protection than others therefore resulting in higher costs. Our rates for a consumer unit replacement vary accordingly, but an average size unit (6-10 circuits) in a standard 1-3 bedroom property would cost around £400 plus VAT.
This is a common statement, and again similar to the brakes on a car, you need a specialist to assess its safety. Our testing equipment will simulate different kinds of faults on your electrical system and will assess how the consumer unit dealt with those faults and determine all possible outcomes.
Not necessarily. Old fuseboxes such as rewireable fuses or cartridge fuses are not always deemed unsafe, they are ok for overload protection, but they do not meet the current regulations in terms of disconnection times, earth leakage detection, surge protection and arc detection.
Over time, as electrical accidents and disasters have happened, the industry has adapted to prevent the same things occurring again and as a result, newer safer devices have been implemented and through the EICR process, these have been introduced into homes and businesses.
