Our Electrical Installation Condition Reports (EICRs) provide a detailed assessment of fixed electrical installations, ensuring compliance with BS 7671:2022 (18th Edition Wiring Regulations), the Electricity at Work Regulations 1989, and industry best practices.
Whether you need an inspection for licensing, insurance, mortgage approval, or health and safety compliance, our reports give you the certified documentation required.
We inspect a wide range of commercial, industrial, and specialist installations, including:
🏢 Offices & commercial buildings
🏭 Warehouses & factories
⚙️ Construction sites & agricultural premises
🎪 Event & festival electrical setups (BS 7909)
🚤 Marinas, caravan parks & specialist locations
An EICR, also known as:
✔ Fixed Wiring Test Report
✔ Fixed Wiring Certificate
✔ Periodic Inspection Report
is an industry-standard inspection that evaluates the safety, condition, and compliance of an electrical installation.
An EICR is a detailed assessment of a building’s fixed electrical systems.
It identifies:
✔ Wiring defects & overloaded circuits
✔ Signs of wear and deterioration
✔ Risk of electric shocks & fire hazards
✔ Incorrect earthing & bonding arrangements
Upon completion, you’ll receive an EICR certificate, categorizing any issues found:
🔴 Code 1 (C1) – Immediate Danger – Requires urgent action as there is an immediate risk to safety.
🟠 Code 2 (C2) – Potential Danger – Issues should be corrected as soon as possible to prevent hazards.
🔵 Further Investigation (FI) – Further testing or assessment is needed before determining compliance.
✅ Code 3 (C3) – Improvement Recommended – The installation is safe but could be upgraded for better safety or efficiency.
If any C1 or C2 faults are found, remedial work must be completed before the installation is deemed safe and compliant.
🔹 Landlords – Legally required every 5 years for rental properties under the Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020.
🔹 Businesses & Commercial Premises – Recommended every 5 years for offices, shops, and warehouses.
🔹 Industrial Sites – Inspections required every 3 years due to higher electrical loads and harsher environments.
🔹 Public Buildings (Schools, Hospitals, Care Homes, Hotels) – Typically required every 1-5 years, depending on usage, age and risk assessment.
🔹 Construction Sites – Every 3 months under BS 7671 special location requirements.
We also provide specialist inspections for high-risk environments, including:
🏗 Construction & demolition sites
🌱 Agricultural, horticultural & farm installations
🏊 Swimming pools, saunas & steam rooms
🎡 Amusement parks, fairgrounds & theme parks
⚡ Solar PV systems & electric vehicle charging stations
Ensuring that electrical installations are safe, compliant, and regularly inspected is not just best practice—it is a legal requirement under multiple UK regulations.
Regular electrical testing and inspection help prevent accidents, protect businesses from liability, and maintain compliance with BS 7671:2022, the Electricity at Work Regulations 1989, PUWER, and the Health & Safety at Work Act 1974.
The British Standard for Electrical Installations (BS 7671) outlines the design, installation, testing, and maintenance requirements for electrical systems in the UK. It states that:
Failure to comply with BS 7671 can result in electrical hazards, non-compliance with insurance requirements, and increased liability for businesses and landlords.
These regulations place a legal duty on employers, landlords, and duty holders to ensure that electrical systems are safe for use and properly maintained. Key requirements include:
This legislation places a general duty of care on employers to ensure the health, safety, and welfare of employees and the public. Under Section 2(1), businesses must:
Failure to comply with this Act can result in enforcement action by the Health & Safety Executive (HSE), prosecution, and significant financial penalties.
PUWER applies to all work equipment, including electrical systems, and requires that:
For businesses, non-compliance with PUWER can result in fines, increased liability, and risk of injury to employees or the public.
For landlords, the Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020 require that:
An Electrical Installation Condition Report (EICR) is the official documentation that demonstates compliance with these legal requirements. It provides a detailed record of an electrical installation’s condition, any faults identified, and recommended remedial actions.
At ESI: Electrical Safety Inspections, we ensure that your business, workplace, or rental property meets all legal electrical safety requirements.

Electrical safety is a legal requirement, and ensuring your installation is safe, compliant, and well-maintained is essential for businesses, landlords, and industrial sites.
An EICR (Electrical Installation Condition Report) identifies potential hazards, ensures compliance with BS 7671:2022 (18th Edition Wiring Regulations), and helps prevent electrical faults, fires, and legal risks.
In this section, we answer the most common EICR-related questions, covering legal requirements, inspection procedures, power shutdowns, IT department coordination, meter access, and minimising disruption.

If serious defects are found and left unaddressed, you risk:
Yes. We need to access the main electrical intake and distribution boards, we also need access to the electricity and gas meters to verify earth bonding.
If these areas are locked or difficult to access, they should be unlocked before the inspection.
No. EICRs cover fixed electrical installations only.
Portable Appliance Testing (PAT Testing) is required for plug-in equipment.
Fixed Appliance Testing (FAT) is required for hard-wired equipment like machinery, heaters, hand-driers, etc.
To help minimise disruption, we can also organise Portable Appliance Testing (PAT) and Fixed Appliance Testing (FAT) at the same time, ensuring all aspects of your electrical system are inspected in one visit.
No. Emergency lighting and fire alarms require separate inspections under BS 5266 and BS 5839.
