Practical electrical compliance guidance
Distinguishing legislation, British Standards and good practice — written for duty holders and reviewed by a competent person.
What Is an EICR?
An EICR is a formal, documented assessment of a fixed electrical installation against BS 7671, recording classified observations and a satisfactory or unsatisfactory outcome.
Learn moreWhat Is Included in an EICR?
An EICR covers the consumer unit, protective devices, circuits, earthing and bonding, and a representative sample of the installation, with observations and test results recorded.
Learn moreWhat Do C1, C2, C3 and FI Mean?
C1 = danger present (immediate action); C2 = potentially dangerous (prompt remediation); C3 = improvement recommended; FI = further investigation required. C1, C2 and FI make a report unsatisfactory.
Learn moreWhat Happens After an Unsatisfactory EICR?
C1, C2 and FI observations must be addressed. A remedial quotation is provided, work is completed, affected circuits are re-tested and appropriate certification is issued.
Learn moreHow Often Is a Commercial EICR Required?
Commercial inspection intervals are risk-based and depend on installation type and use. Intervals are guided by BS 7671 recommendations rather than a single fixed legal period.
Learn moreLandlord EICR Responsibilities Explained
Private landlords in England must have the fixed installation inspected and tested at least every five years, provide the report to tenants and remedy issues within the timescales set by the 2020 Regulations.
Learn moreHMO Electrical Safety Requirements
HMOs carry additional electrical and fire safety duties, often linked to licensing conditions, including periodic inspection and appropriate detection systems.
Learn moreEICR Remedial Works Explained
Remedial works rectify EICR observations in priority order; affected work is inspected and tested and appropriate certification is issued on completion.
Learn moreWhen Should a Consumer Unit Be Upgraded?
A consumer unit may need upgrading where protection is inadequate, components are obsolete or damaged, or where an EICR records observations relating to the board.
Learn moreRCD, RCBO, SPD and AFDD Differences
RCDs detect earth faults; RCBOs combine earth-fault and overcurrent protection per circuit; SPDs protect against transient overvoltages; AFDDs detect arc faults.
Learn moreEmergency Lighting Testing Frequencies
BS 5266 good practice indicates monthly brief function tests and an annual full-duration test, with records kept in a logbook.
Learn moreFire Alarm Testing Responsibilities
BS 5839 good practice indicates weekly user tests and periodic servicing by a competent person, with responsibilities sitting with the duty holder.
Learn morePAT Testing and Risk-Based Frequencies
There is no single legal PAT interval; in-service inspection and testing frequency is risk-based, depending on equipment type and environment.
Learn moreFixed-Wire Testing for Facilities Managers
Fixed-wire testing (periodic inspection of the installation) helps FMs evidence compliance; intervals are risk-based and coordinated around site access.
Learn moreElectrical Asset Registers Explained
An electrical asset register is a structured record of installations and equipment used to plan inspections, track certificates and prioritise remedials.
Learn morePlanned Preventative Electrical Maintenance
Planned preventative maintenance schedules inspection and servicing to reduce failures and maintain compliance across a portfolio.
Learn moreWorkplace EV-Charging Site Requirements
Workplace EV charging depends on available electrical capacity, load management, charger selection, metering, access control and safe cable routing.
Learn moreEV Charging for Apartment Blocks
Apartment-block charging must address supply capacity, freeholder and landlord permissions, shared access, metering and load management.
Learn moreEV Load Management Explained
Load management dynamically shares available electrical capacity across chargers so more vehicles can charge without exceeding the site's maximum demand.
Learn morePreparing a Property Portfolio for Electrical Testing
Preparation includes consolidating certificate dates, arranging access, prioritising overdue properties and maintaining an up-to-date asset register.
