Commercial EICR in Chesterfield and north Derbyshire
Most commercial EICR pages say the law requires an inspection every five years, or every three for an office. It does not. The Electricity at Work Regulations require you to maintain the installation so it does not become dangerous, and to decide, record and review how often it is checked.
No interval is fixed in law. Recommended maximums come from BS 7671 guidance, not statute.
Where is the property?
The postcode tells us whether we cover you.
What you are getting
The law requires maintenance, not an interval
Maintain the installation so it does not become dangerous
That is the obligation under the Electricity at Work Regulations 1989. A duty of outcome, not a schedule, which is why it names no interval.
Decide the frequency, and write it down
HSE's position: test often enough that deterioration is unlikely to lead to danger. You decide, record it, and adjust as faults appear.
Recommended maximums come from guidance, not law
BS 7671 gives recommended maximum intervals by premises type. Worth following. Not a legal requirement, whatever you are told.
Insurers and leases often set one anyway
In practice the binding interval is usually contractual: an insurance condition or a repairing clause. Check what yours says before assuming a number.
What you get
A report records circuits, codes and limitations
The verdict is the least useful part. What matters is the schedule of test results behind it, the coded observations, and an honest record of anything the inspection could not reach.
A ticked box and nothing else is a verdict with no working shown. Worth knowing before you accept one, whoever arranged it.
What the law says
Statute sets no commercial inspection interval
The first row is the important one. There is no statutory inspection interval for commercial premises, and a page telling you otherwise is either mistaken or selling you something.
| Electricity at Work Regulations 1989 | Duty to maintain so as to prevent danger. No interval is set. |
|---|---|
| Inspection frequency | Risk-based. The duty holder decides it, records it and reviews it. |
| BS 7671 guidance | Recommended maximum intervals. Guidance, not statute. |
| Insurance or lease conditions | Frequently the interval that actually binds you |
Sources
This describes the law in England. The Welsh and Scottish positions differ, Scotland's repairing standard also covers portable appliances, which the England duty on private landlords does not. It is general information, not legal advice. Last checked against the primary sources on 27 August 2026.
How it works
Commercial testing needs planned isolation
Commercial testing means planned isolation, and isolation means downtime. Scheduling is usually harder than the electrical work.
Tell us the premises and the constraint
Premises type, rough board count, single or three phase, and when you can be without power. That last answer shapes everything else.
We match an electrician to the type of installation
A small trade unit and a multi-board industrial installation are not the same job. Every check we run is on the vetting page.
Isolation is planned, sometimes in phases
Larger installations are often done over several visits so no shutdown takes the whole site. Agree that up front, not on the day.
Report, schedule and a recommended interval
The report carries a recommended next date. That is a better basis for your risk decision than any rule of thumb.
Areas covered
We cover eight towns across north Derbyshire
Chesterfield's trade and industrial units, and the commercial premises around junction 28 at South Normanton.
Do we cover your postcode?
Type the first part, like S40 or DE45. No need for the whole thing.
Who does the work
Every electrician clears six checks
We do not carry out the inspection. We put you in touch with an electrician who does. An EICR is worth what the person signing it is worth, so these checks are the product. Each is verified against the issuing body's own register, not taken from a logo.
Competent to inspect and test
Inspection and testing carries its own qualification. A good installer is not automatically the right person to sign a report.
Registered with a competent person scheme
Checked on the scheme's own public register, not a badge on a website.
Public liability insurance, in date
We check the certificate and the expiry date, not just that one exists. A lapsed policy is the most common reason to turn someone away.
Reports that carry their schedule
We look at an electrician's reports before sending them a job. The schedule of results is the part worth checking.
Working to the current standard
BS 7671 as currently amended. The 2026 amendment changed what makes a report unsatisfactory, and not everyone has caught up.
A public record worth reading
We read what previous customers wrote instead of counting stars. We publish no figure of our own, because we have none.
Scheme registration and insurance details come with your quote, so you can check them against the public register yourself. How we choose electricians sets out every check, including what gets someone turned away.
Next step
Arrange a commercial inspection
Premises type, board count, and when you can be without power. If your insurer has set an interval, say what it is.
Questions
Commercial questions
Is a commercial EICR a legal requirement every five years?
No, and this is worth being clear about because it is stated as fact almost everywhere. The Electricity at Work Regulations 1989 require you to maintain the installation so it does not become dangerous. They set no interval. Recommended maximum intervals come from BS 7671 guidance.
Then how often should we have one?
HSE's position is that testing should be often enough that there is little chance of deterioration leading to danger, with the frequency decided, recorded, and adjusted according to the faults found. The report on your installation will carry a recommended next date, which is a better starting point than a general figure.
Our insurer asks for a current certificate. Does that change things?
It changes what binds you in practice. An insurance condition or a repairing clause in a lease is a contractual obligation rather than a statutory one, but it is no less real. Check what yours actually says rather than assuming a number.
Is this the same as PAT testing?
No. This covers the fixed installation: the wiring, the boards, the fixed equipment. In-service testing of portable appliances is a separate exercise answering a different question.
We let commercial units out. Does the landlord duty apply?
The five-yearly statutory duty applies to rented dwellings, not to commercial lettings. Your obligations as a commercial landlord come from the lease and from the general duty to maintain, which is a different analysis.
