An EICR is a formal document produced following a rigorous technical assessment of the hardwired electrical installation within a property. It identifies damage, deterioration, Code C1 or C2 defects, and conditions that may be dangerous, ensuring your site complies with BS 7671:2018+A3:2024.

It depends on the property type. Standard domestic owner-occupied homes should be tested every 10 years. Private rental properties and commercial environments require an inspection every 5 years (or at change of tenancy). Industrial sites require testing every 3 years.

Under the Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020, local authorities can impose financial penalties of up to £30,000 on landlords who fail to provide a valid, "Satisfactory" EICR for their tenants.

This depends on your maximum demand and current earthing arrangements. Modern EV chargers require specific RCD protection and often necessitate a Type 2 Surge Protection Device (SPD). TMUK Group Ltd can assess your current distribution board to determine if an upgrade or separate dedicated circuit is required.

Warning signs include frequent tripping of Miniature Circuit Breakers (MCBs) or RCBOs, flickering lights, discoloured or warm socket outlets, a burning smell, or the presence of outdated materials such as wooden-backed consumer units or old aluminium wiring.

An RCD or RCBO is a life-saving device designed to prevent fatal electric shocks. It constantly monitors the electrical current and will instantly disconnect the circuit (typically within 40 ms) if it detects a fault of 30 mA or more leaking to earth.

Locate your consumer unit, identify the tripped MCB or RCBO (it will be in the downward or "off" position), and firmly switch it back to the "on" position. If it trips again immediately, leave it off and call TMUK Group Ltd to investigate the fault, as this indicates a serious issue.

Single-phase power (230 V) is typically used for domestic and light commercial applications. Three-phase power (400 V) is utilised in industrial and large commercial settings to safely supply heavy machinery and balance massive electrical loads across three distinct alternating currents.

Minor electrical work, such as a straight swap of a socket faceplate, can be done by a competent person. However, major work (like altering circuits or changing a distribution board) must comply with Part P of the Building Regulations and should only be carried out by a registered, NICEIC-approved electrician.

To protect modern electronics, computers, and solar PV/battery storage systems, TMUK Group Ltd recommends installing a Type 2 Surge Protection Device (SPD) directly within your consumer unit, as now mandated for many installations under the latest BS 7671 regulations.
