A commercial EICR, short for Electrical Installation Condition Report, is the document that confirms the fixed wiring in a business premises is safe and fit for purpose. For most commercial properties in Beaconsfield and the surrounding towns, one is expected every five years at a minimum. That five-year cycle sounds straightforward, but the moment you look at who pays, who arranges it, and what happens when the result is not satisfactory, things become less clear. This guide walks through the practical side from both sides of a lease.
Who actually has to arrange this, and when?
The short answer is that it depends on your lease, but the longer answer is more useful. Most commercial leases written in the last twenty years place responsibility for the fixed electrical installation with the landlord. The fixed installation means everything built into the fabric of the building: the main incoming supply, the consumer unit or distribution boards, all the wiring in the walls and ceilings, the sockets and switches, and the fixed lighting. If a fault develops in any of that, it is generally the landlord’s problem to fix and the landlord’s job to prove it is safe.
The tenant, by contrast, is usually responsible for the equipment they bring into the building. That means computers, display fridges, extraction fans they have installed, and any wiring they have added during a fit-out. If the lease granted the tenant permission to carry out electrical works, those works now sit in a grey area, and it is worth getting legal advice on who carries the liability.
When you sign a new lease, do not rely on the previous tenant’s EICR even if it is less than five years old. You do not know what was done to the installation between inspections. Commission your own before you move equipment in.
What do insurers and licensing bodies actually ask for?
Most commercial insurers ask to see a current EICR as part of the policy documentation or renewal process. Some will ask for one every five years. Others, particularly for premises with higher electrical demand such as catering kitchens, workshops or hair salons in Amersham or Marlow, may require one every three years. If you cannot produce a satisfactory report, the insurer may load the premium, add an exclusion for electrical damage, or decline to cover you at all.
Licensing authorities follow a similar pattern. Premises licensed for the sale of alcohol, food businesses subject to environmental health inspection, and childcare settings typically need to produce a satisfactory EICR as part of the licence application or renewal. The licensing officer is not an electrician and is not there to judge the quality of the wiring: they simply want to see the certificate. If you cannot produce one, the licence can be held up.
The practical upside of running on a five-yearly cycle is that it forces you to catch problems before they become expensive. Wiring that was adequate for a retail unit in 2010 may be under strain if the premises has since been used as a beauty salon with banks of heated equipment running all day.
How is a commercial inspection priced?
This is the point where commercial EICRs differ most obviously from domestic ones. A domestic EICR is usually priced by the number of bedrooms because that gives a reasonable proxy for the number of circuits. Commercial properties do not work that way. A 40 square metre office might have more circuits than a 200 square metre shop, depending on how it has been fitted out.
Registered electricians price commercial EICRs by the number of circuits, the number of distribution boards, and the complexity of the installation. Three-phase supplies, sub-main cables running between buildings, and emergency lighting systems all add time. Easy access to the boards speeds things up; boards buried behind racking or in occupied server rooms slow things down.
For a sense of what you are looking at, see the range at the top of this page. That range covers most small to medium commercial premises in towns like Gerrards Cross, Wooburn Green and Chalfont St Peter. Larger premises with multiple boards, or those with specialist systems, will sit higher.
For anything more involved, including a full rewire or an upgrade to the distribution system, take a look at commercial electrical fit-out in Beaconsfield for more on how that work is scoped and priced.
What does the inspector actually check?
The inspection follows a set methodology. The electrician works through the entire fixed installation, testing each circuit in turn. For each circuit they check insulation resistance, earth continuity, polarity, and the correct operation of protective devices. They look at the consumer unit or distribution boards for signs of overheating, incorrect fusing, or modifications that do not meet current standards. They check sockets, switches, and fixed luminaires for mechanical damage and correct wiring.
At the end, every fault is graded. A C1 means danger is present and the installation should not be used until the fault is fixed. A C2 means potentially dangerous: not an immediate shutdown, but it must be remedied before a satisfactory certificate can be issued. A C3 is a recommendation for improvement, something that does not meet current best practice but is not dangerous in its present state. C3 items do not prevent a satisfactory certificate, but they are worth noting for your maintenance schedule.
The report itself lists every test result and every observation. It is a technical document, but a decent electrician will talk you through the findings in plain language so you know what needs doing and in what order.
What happens after an unsatisfactory result?
If the report comes back with C1 or C2 items, those must be remedied before the installation can be certified as satisfactory. In practice that usually means booking the remedial work at the same time as you receive the report. For a small office, it might mean replacing a worn socket or tightening connections in the board. For an older premises that has been through multiple tenancies, it might mean rewiring a circuit or replacing the consumer unit entirely.
Do not sit on an unsatisfactory report. If your insurer finds out that you knew about a C1 fault and left it in place, they have grounds to reject a claim. If an incident causes injury and the report is in your files unactioned, the legal consequences are serious. The right approach is to get the remedial works scoped immediately and book them in as soon as your trading schedule allows.
If the premises needs to stay open during remedial work, that is entirely possible in most cases. A competent electrician can isolate individual circuits, work on one section at a time, and schedule the brief outages for early morning or after hours.

What should a tenant do if the landlord refuses to act?
This situation comes up more often than it should, usually in older buildings where the landlord is reluctant to spend money on infrastructure. If your lease places the responsibility on the landlord and they are not acting, your first step is a written request with a reasonable deadline. Keep copies of everything.
If the landlord still does not act and your insurer or licensing authority is pressing you, you have the option of commissioning the EICR yourself, paying for it, and then pursuing the landlord for the cost through the lease’s dispute mechanism or, if necessary, through the courts. That is a last resort, but the alternative, operating in a building with an uninspected installation, is not sensible.
Some tenants in this position find it helpful to have the electrician write a short covering note explaining the urgency of the inspection findings. That can be more persuasive than a letter from the tenant alone.
