Local response & clear paperwork
Based in Knebworth, DC Electrix provides quick local visits, visible labelling and an Electrical Installation Certificate you can keep for sale or insurance needs.
Why replace your consumer unit? Many older fuseboxes lack essential protection such as RCDs or individual RCBOs. That increases the chance of nuisance tripping, dangerous earth faults and appliance-damaging surges. A modern consumer unit fitted with RCD/RCBO protection, a Surge Protection Device (SPD) and clear circuit labelling brings your installation up to current safety standards.
How DC Electrix handles the job: our NAPIT-registered electricians perform a full earthing assessment, replace the consumer unit with appropriately rated RCDs/RCBOs, fit surge protection where needed, and carry out final loop, insulation and RCD tests. Once complete we issue an Electrical Installation Certificate and update any required paperwork for Building Regulations Part P.
