Electrical compliance
EICR testing and electrical compliance you can rely on
JKS are an NICEIC approved contractor that offers comprehensive electrical testing and asset stewardship programmes for organisations within the industrial, commercial and public sectors. By providing a high-quality testing service we can foresee any future problems ahead of time, potentially cutting your costs.
Electrical installations deteriorate with age, use and alteration. Connections loosen, insulation breaks down, circuits get extended and protective devices stop matching the loads they serve. Regular inspection and testing finds these issues while they are still cheap to fix — before they cause a fire, an electric shock or an unplanned shutdown.
We combine thorough testing with clear reporting and practical recommendations, so you know exactly where you stand and what to do next.

Why it matters
Why regular electrical testing protects your organisation
Electrical compliance is not just paperwork. It protects people, keeps your premises trading and gives you evidence when insurers, auditors or enforcing authorities ask for it.
Meet your legal duties
Employers and those in control of premises must maintain electrical systems to prevent danger. A current EICR is your strongest evidence.
Reduce fire risk
Overloaded circuits, loose terminations and damaged cables are common ignition sources. Testing finds them early.
Satisfy insurers and landlords
Insurance policies, leases and fire risk assessments frequently require up-to-date electrical certification.
Control costs
Planned remedial work is cheaper than emergency repairs, lost trading and damaged stock after a failure.
Periodic inspection
EICR testing in London & Kent
An Electrical Installation Condition Report (EICR) is the formal record of a periodic inspection and test of your fixed wiring — distribution boards, cables, sockets, lighting circuits, fixed equipment and earthing and bonding arrangements. It is the main way duty holders show they are meeting the requirement of the Electricity at Work Regulations 1989 to maintain electrical systems so as to prevent danger.
Our NICEIC-qualified inspectors test to the current edition of BS 7671, recording any departures as C1 (danger present), C2 (potentially dangerous), C3 (improvement recommended) or FI (further investigation required). The overall result is either satisfactory or unsatisfactory.
Read our guides to EICRs for commercial properties and understanding EICR codes for more detail.
How often?
Typical EICR inspection intervals by premises type
The IET’s Guidance Note 3: Inspection & Testing sets out recommended maximum periods between periodic inspections. Common examples include:
| Type of premises | Recommended maximum interval |
|---|---|
| Offices, shops and general commercial premises | 5 years (or change of occupancy) |
| Restaurants and hotels | 5 years |
| Educational establishments | 5 years |
| Hospitals | 5 years |
| Residential accommodation (e.g. care homes, HMOs) | 5 years |
| Domestic, privately rented (England) | 5 years — required by the Electrical Safety Standards in the Private Rented Sector Regulations 2020 |
| Industrial premises | 3 years |
| Leisure complexes, theatres and places of public entertainment | 3 years |
| Agricultural and horticultural premises | 3 years |
| Swimming pools, petrol filling stations and marinas | 1 year |
| Construction site installations | 3 months |
Note: These are maximum intervals, not targets. The inspector will recommend a shorter period where the installation is old, heavily used, in a harsh environment or showing signs of deterioration — commercial kitchens are a common example. Insurers and leases may also set their own requirements.

Beyond the EICR
Emergency lighting, witness testing and asset stewardship
Emergency lighting tests to BS 5266
Emergency escape lighting must work the moment the mains supply fails. BS 5266-1 recommends a brief monthly functional test of every luminaire and sign, and an annual test for the full rated duration — typically three hours. We carry out both, record results in your log book, replace failed batteries and lamps and issue certification. See our guide to emergency lighting testing duties.
Book emergency lighting testing
Witness testing reports & consultancy to BS 7671
When another contractor completes new installation work, you need confidence that the tests were done properly and the results comply. We independently witness testing, review certification and schedules of test results, and report on compliance with BS 7671 — giving clients, landlords and project teams an impartial view before handover.
Discuss witness testing
Asset stewardship
Many buildings lack accurate records of what is installed. We build and maintain electrical asset registers, produce schematics and distribution board schedules, and provide change-control procedural support so alterations are planned, recorded and reflected in your drawings. Good records make testing faster and future works safer.
Asset management within FMPAT testing
Portable equipment such as kettles, kitchen appliances, IT equipment and power tools must also be maintained. We take a risk-based approach to frequencies in line with the IET Code of Practice for In-service Inspection and Testing, label equipment and provide a full register. Read PAT testing explained.

FAQ
Frequently asked questions
How often does a commercial property need an EICR?
IET Guidance Note 3 recommends a maximum interval of five years for most commercial premises such as offices, shops, restaurants and hotels, with shorter intervals for industrial sites, leisure facilities and special locations. The inspector may recommend a shorter interval based on the condition and use of the installation.
Is an EICR a legal requirement for businesses?
The Electricity at Work Regulations 1989 require electrical systems to be maintained so as to prevent danger. Periodic inspection and testing, recorded on an EICR, is the recognised way to demonstrate that duty is being met, and insurers and landlords commonly require it.
Will testing disrupt my business?
Testing requires circuits to be isolated for short periods. We plan the sequence with you and can work early mornings, evenings or weekends to keep critical areas such as kitchens, tills and IT running.
What happens if my EICR is unsatisfactory?
An unsatisfactory result means at least one C1, C2 or FI observation was recorded. We explain each item, provide a prioritised quotation for remedial work and issue the appropriate certification once the work is complete.
How often should emergency lighting be tested?
BS 5266-1 recommends a short functional test every month and a full rated-duration test every year, with results recorded in a log book.
Do you provide PAT testing as well as fixed wire testing?
Yes. We carry out risk-based in-service inspection and testing of portable equipment in line with the IET Code of Practice, and can combine it with your EICR visit.
