What is an Electrical Installation Licence?
An Electrical Installation Licence (EIL) is a licence issued by the Energy Market Authority (EMA) for the electrical installation itself — the switchboards, wiring, and equipment in a building — as distinct from the personal licence held by a Licensed Electrical Worker. If your premises fall within the licensable categories, operating the electrical installation without a valid EIL is an offence under the Electricity Act.
Which Premises Need an EIL?
Broadly, an electrical installation must be licensed when it is in non-domestic premises and meets conditions such as:
- The installation is supplied at high voltage (above 1kV — for example, premises with their own 22kV substation or transformers), or
- The installation has an approved load exceeding 45 kVA and is used for non-domestic purposes, or
- The installation supplies temporary premises such as construction sites, or
- Electricity is supplied to third parties within the premises (for example, a landlord on-supplying tenants).
In practice this captures most factories, warehouses, shopping malls, office towers, hotels, hospitals, schools, data centres, and construction sites. A typical HDB flat or small shop with a low approved load does not need one.
Not sure whether your premises qualify? Your approved load is stated on your SP Group supply documents. If it's above 45 kVA, or you have your own transformer, assume you need an EIL until confirmed otherwise.
How the Application Works
- Appoint a LEW — an EIL application must be made through a Licensed Electrical Worker whose licence class covers your installation size. The LEW becomes the person "taking charge" of the installation.
- Inspection and testing — the LEW inspects the installation and carries out the required tests to confirm it complies with SS 638 and the Electricity (Electrical Installations) Regulations.
- Rectification — any defects found must be fixed before the LEW can certify the installation.
- Submission to EMA — the LEW submits the application with the test records and certification through EMA's online portal.
- Licence issued — EMA issues the EIL, typically valid for 12 months.
The Annual Renewal Cycle
An EIL is not a one-off document. Every year, before the licence expires, the appointed LEW must re-inspect the installation, carry out the periodic tests, certify that it remains safe, and submit the renewal to EMA. Missing the renewal deadline means the installation is unlicensed — with the same legal exposure as never having had a licence.
A well-run renewal is uneventful: the LEW schedules the inspection a month or two ahead of expiry, tests during a planned window (often combined with shutdown servicing), and submits with time to spare. Problems arise when renewals are left to the last week and defects are found.
What Happens If You Operate Without One?
- Fines and prosecution under the Electricity Act for the owner or occupier
- Potential disconnection issues and complications with SP Group
- Insurance claims after an electrical incident may be compromised
- Liability exposure for directors and management if workers are harmed
