For ordinary business premises in England, there is no universal legal rule requiring an Electrical Installation Condition Report (EICR) every five years. That does not make inspection and testing optional. The duty is to keep electrical systems safe throughout their working life.
If you are arranging a commercial EICR in Falmouth, the practical question is whether the inspection interval fits your premises, maintenance history and written obligations, rather than a generic checklist.
For related work and planning, see our EICR testing page.
Is a five-year EICR legally required for every Falmouth business?
No single five-year statutory interval applies to all ordinary non-domestic workplaces. Regulation 4(1)–(2) of the Electricity at Work Regulations 1989 requires systems to be constructed and maintained, so far as reasonably practicable, to prevent danger. It does not name an EICR or prescribe a universal commercial inspection interval.
The legal duty continues between inspections; it is not discharged simply by booking a report. HSE advises arranging inspection and testing of fixed wiring to minimise the risk of deterioration leading to danger, normally using a competent person.
A commercial EICR assesses whether the installation is suitable for continued use. It informs the maintenance programme; it does not replace it. Where premises are leased, make sure responsibility for electrical maintenance is clear so the inspection is actually arranged.
Where does the five-year EICR rule come from?
One source of confusion is the separate housing regime. In England, the statutory five-year inspection requirement described in GOV.UK landlord guidance applies to qualifying rented homes, including homes in the private and social rented sectors. It concerns homes occupied as a tenant’s only or main residence and has defined exceptions.
Cornwall Council’s five-year statement also appears in its landlord guidance. Neither that local summary nor the housing rule should be read as a universal deadline for every commercial lease. A commercial tenant paying rent is not, for that reason alone, covered by the rented-home inspection regime.
Five years can nevertheless apply to a business installation. It may be a competent person’s recommendation, or a condition in a lease, insurance policy, premises licence or sector-specific arrangement. Check the wording of the documents that actually apply to your site.
Mixed-use sites need a closer look
Where a site combines business premises and accommodation, check which rules apply to each part. Do not assume all accommodation is covered in the same way: the GOV.UK guidance lists mobile homes and caravans among the exceptions. A mixed-use site needs case-specific checking rather than one timetable applied to the whole property.
How should a commercial site choose its inspection interval?
IET guidance says subsequent inspection intervals should be recommended by a competent person. Suggested initial frequencies are recommendations, not legal requirements. A generic schedule can be a starting point, but it does not replace assessment of your installation.
Four factors behind the recommended date
- Installation and equipment. The type of installation and equipment, and their condition, matter more than the label ‘commercial’.
- Use and operation. Consider operating hours, intensity of use and whether the installation still serves the activities it was assessed for.
- Maintenance history. Both the frequency and quality of previous maintenance affect the assessment.
- External influences. Damp, dust, corrosion or potential physical damage should be considered where they are relevant to the actual site.
A lightly used office and a heavily used workshop need not receive the same recommendation. Equally, a Cornwall postcode alone is not a reason to shorten an interval: actual exposure and condition matter.
IET’s EICR model form records the recommended next-inspection date and the reason for it. Ask for that reasoning to be clear. Do not extend an existing recommendation merely because the general workplace duty does not specify five years.
When should the recommended date be reviewed?
A recommended date is not a guarantee that the installation will remain safe until then. A report recommending another inspection in five years does not justify leaving a developing problem until year five. Maintenance still has to continue between reports.
Seek competent advice if the premises change use, electrical additions or alterations are made, operating demands change significantly, or damage, deterioration or recurring faults appear. These are reasons to review the inspection and maintenance plan; they do not automatically mean the whole installation needs an immediate new EICR.

For example, a store converted into a workshop may have different equipment, usage and environmental conditions from those considered at its last inspection. The useful question is whether the previous recommendation still fits, not simply whether the old date has passed.
Also review the timetable if a lease, insurance policy or licensing condition introduces a tighter requirement. Tell the competent person what has changed so the appropriate response can be assessed. If danger is suspected, seek urgent professional assistance rather than waiting for the routine inspection.
Do not attempt electrical testing yourself to decide whether a scheduled inspection can wait.
What should a Falmouth site manager check before booking?
Start with your electrical inspection records, the installation’s current circumstances and the written obligations affecting the premises. For a Falmouth business, fixed-wiring inspection should be booked against that combined picture, not just the age of a document.
- Read the recommended date and explanation. If the report cannot be found, or the recommendation is unclear, ask for competent advice rather than guessing a date.
- Describe what has changed. Note changes in activity, equipment, use of space, maintenance arrangements or known electrical problems.
- Check site-specific requirements. Look at the relevant lease, insurance and licensing documents rather than relying on what a neighbouring business was told.
- Ask for a suitable plan. Discuss the timing of fixed-installation inspection with a competent electrical contractor, alongside continuing maintenance.
If you are taking over premises, ask a competent person how the existing report and your intended use affect the next inspection. A new tenancy is not a sound basis for assuming you have a fresh five-year period.
In your enquiry, separate the inspector’s technical recommendation from any insurance, lease or licensing deadline. Those are different reasons for a date, and one should not silently replace the other. If they differ, flag both rather than choosing whichever gives the longest gap. If the recommended inspection date has already passed, arrange competent advice promptly rather than waiting for another anniversary.
The useful outcome is a clear, justified next-inspection date, with a separate plan for the maintenance needed between inspections.
