It records the condition of that installation against current standards and lists anything that is unsatisfactory. Commercial EICRs, often called fixed wire testing or periodic inspection, are what insurers, managing agents, main contractors and enforcing bodies ask for when they want assurance that the building itself is electrically sound. Unlike PAT testing, this is about the infrastructure: what happens when a circuit is overloaded, when an earth path is compromised, or when someone has added a spur to a board nobody has documented. We carry out commercial EICRs across offices, retail units, warehouses, workshops, care settings, schools and multi-tenanted buildings throughout London and High Wycombe. ### Why professional delivery matters - Sampling and isolation on a live commercial building must be planned. Getting supplies down safely, at a time that does not stop trading, is as much of the job as the testing itself. - Observation coding is a judgement call with real consequences: a C1 means danger present and immediate action, a C2 means potentially dangerous and urgent remedial, a C3 is an improvement recommendation. Over-coding creates unnecessary spend; under-coding leaves risk in the building. - Boards in commercial premises are rarely as-built. Undocumented alterations, borrowed neutrals, mixed protective devices and abandoned circuits all need tracing before results mean anything. - An unsatisfactory report is only useful if the remedial route is clear; we quote and carry out the works needed to bring the installation to a satisfactory, documented state. ### Who this is for - Commercial landlords and property owners evidencing installation condition - Facilities management companies running planned maintenance programmes - Managing agents responsible for landlord supply and communal areas - Offices, retail units, warehouses and workshops - Main contractors handing over or taking on a building - Multi-site businesses standardising compliance across a portfolio ### When it is needed - Typically every five years for commercial installations, or shorter in higher-risk environments - At change of occupancy, lease renewal or building handover - When an insurer or broker requests evidence of installation condition - Before or after significant alterations, refits or additional load - When nuisance tripping, overheating accessories or scorching appear - As part of a pre-acquisition or pre-tender due diligence pack The cost of leaving it ## What an expired or ignored EICR leads to A fixed installation degrades quietly. Terminations loosen and heat, insulation ages, protective devices lose reliability, and each undocumented alteration erodes the original design. None of it announces itself until a circuit fails, an accessory scorches, or someone receives a shock. Commercially, a missing or expired EICR is one of the fastest ways to stall a transaction. Lease negotiations, insurance renewals, tenders and contractor pre-qualification all ask for it, and none of them accept a promise that testing is booked. Where an incident does occur, absence of a current report is the first thing raised. The worst outcome is the unsatisfactory report received under time pressure: C1 and C2 observations landing days before a deadline, with remedial works, isolation windows and costs that nobody has budgeted for. ### Common mistakes we are called in to fix - Treating five years as a rule rather than a guide, when environment, use and alterations may justify shorter intervals. - Commissioning an EICR without agreeing sampling scope, then arguing about coverage after the report lands. - Accepting an unsatisfactory report and filing it: an unsatisfactory EICR is a to-do list, not a certificate. - Allowing repeated minor alterations with no board schedule updates, so the next inspection starts from scratch. - Leaving no time between inspection and deadline for the remedial works the inspection is likely to identify.Call 07597 452886 Our process ## How we deliver commercial eicr certificates Every job follows the same sequence, co-ordinated by a dedicated Operations Manager so attendance fits around your occupants and trading hours. - 01 ### Scope and free quote We confirm the number of distribution boards and circuits, building type, access constraints and sampling scope, then issue a fixed quote before attending. - 02 ### Planning isolation windows Our Operations Manager agrees when supplies can be taken down, and phases the work around trading hours, occupants and critical loads. RAMS are issued on request. - 03 ### Inspection Boards, protective devices, earthing and bonding, accessories, containment and circuit identification are inspected, and existing documentation checked against what is actually installed. - 04 ### Testing Dead and live testing including continuity, insulation resistance, polarity, earth fault loop impedance and RCD operation, recorded circuit by circuit on the schedule of test results. - 05 ### Coding and reporting Each observation is coded C1, C2, C3 or FI with a plain-English explanation of what it means and what it will take to resolve. - 06 ### Digital certificate and remedials The report is issued digitally, typically within one day of payment. Where remedial works are required we quote them so the installation can be brought to a satisfactory, documented state. What you get ## Outcomes, not promises ### Evidence that stands up A complete report with schedules of inspection and test results, ready for insurers, agents, contractors and enforcing bodies. ### Risk found before it becomes an incident Loose terminations, degraded insulation, missing bonding and inadequate protection identified while they are still maintenance rather than emergency. ### Costs you can plan Coded observations with priced remedials let you sequence works across budget periods instead of reacting to a single unaffordable list. ### Trading continuity Isolation planned around occupants and critical loads, with out-of-hours attendance where daytime shutdown is not an option. ### A documented, satisfactory end state We carry out the remedial works ourselves, so observations get closed out rather than carried forward to the next inspection. ### Portfolio consistency Common reporting and scheduling across multiple sites, co-ordinated through one point of contact. ## Inside a commercial EICR: coding, sampling and remedials Two reports on the same building can read very differently depending on how they were scoped and coded. Here is how we approach the detail. ### Observation codes explained C1 means danger is present and there is a risk of injury; immediate action is required and we will make safe where we can on the day. C2 means potentially dangerous, requiring urgent remedial action. C3 is an improvement recommendation and does not on its own make a report unsatisfactory. FI means further investigation is required. A report is unsatisfactory if any C1, C2 or FI is present. We explain each code in plain language so you are not decoding your own report. ### Sampling and scope Full testing of every circuit in a large building is often impractical in a single visit, so a sampling percentage is agreed in advance and stated on the report. Where sampling reveals a pattern of defects, scope is extended rather than the finding being averaged away. Agreeing this before attendance prevents disputes about coverage afterwards. ### Distribution boards and protective devices Board condition, device type and rating, discrimination, RCD and RCBO operation, correct circuit identification and the presence of an accurate board schedule all form part of the inspection. Mixed manufacturers' devices within one board and obsolete boards are frequently found and are recorded with the appropriate code. ### Earthing and bonding Main protective bonding to incoming services, supplementary bonding where required, earthing conductor sizing and the integrity of the earth path are checked. Bonding defects are among the most common findings in older commercial premises and are also among the cheapest to correct. ### Multi-tenanted buildings and landlord supply In multi-let buildings the landlord supply, risers, plant and communal areas are typically inspected separately from demised tenant areas. Defining that boundary up front avoids the common situation where nobody has tested the risers because each party assumed the other had. ### Alterations, refits and additional load Office refits, EV charging, additional HVAC and higher IT density all change the load profile of an installation that may have been designed decades earlier. Inspection considers whether protection and capacity still match actual use, not just whether the original design was compliant. ### Commercial versus residential reports The inspection principles are shared, but commercial installations involve three-phase supplies, sub-mains, larger board counts, mechanical plant and containment systems, and they usually require staged isolation. Residential reports are smaller in scope and driven by letting requirements. We deliver both, and for mixed-use buildings we co-ordinate them together. ### Closing out remedial works Once observations are coded, we quote the works required to clear them. Completing remedials with the same team that carried out the inspection removes the gap where one contractor blames another's coding, and produces a clean documented record from inspection to resolution. ### Related services Residential EICR CertificatesPAT TestingRemedial Works for Fire Compliance Where we work ## Commercial EICR Certificates across London and High Wycombe Our engineers are fully mobile, covering all London boroughs, High Wycombe and the surrounding areas.

Call 07597 452886 How much does a commercial EICR cost?Pricing is quote-led and driven by the number of boards and circuits, building type, access and agreed sampling scope. Send us those details and we will return a fixed price at no cost. How often should a commercial EICR be carried out?Commercial installations are commonly inspected every five years, with shorter intervals in higher-risk environments or where use has changed significantly. We will advise on an appropriate period for your installation. How long will testing take and will you cut the power?Duration depends on board and circuit count. Some testing requires isolation, so we agree windows in advance and can work outside trading hours or phase the work board by board to protect critical loads. What does an unsatisfactory EICR mean?It means at least one C1, C2 or FI observation was recorded. It is not a fine or a shutdown notice; it is a prioritised list of what must be corrected. We quote the remedial works so the installation can be brought to a satisfactory state. When do I get the report?Reports are issued digitally, typically within one day of payment, including the schedules of inspection and test results. Can you carry out the remedial works too?Yes. We provide remedial works for electrical and fire compliance, so observations can be closed out and evidenced rather than carried into the next inspection. Do you provide RAMS for site access?Yes.
