What is a Minor Works Certificate?
By Azzeddine Kebbi, NAPIT-registered electrician and director of Kebbi Electrical Services · Updated 10 November 2026
A Minor Works Certificate, properly a Minor Electrical Installation Works Certificate, is issued for small electrical jobs that add to or alter an existing circuit, such as an extra socket or a new light point. It confirms the work was inspected and tested.
Typical jobs
- Adding a socket or a spur to an existing circuit.
- Adding or moving a light point or switch.
- Replacing an accessory where the circuit is altered.
When it cannot be used
- A new circuit.
- Replacing a consumer unit.
- A rewire.
These need a full Electrical Installation Certificate.
Common questions
Is a Minor Works Certificate a legal requirement?
BS 7671 requires the right certificate for electrical work. Registered electricians issue one for minor works, and buyers’ solicitors and landlords’ agents often ask for them.
What is the difference between a Minor Works Certificate and an EIC?
A Minor Works Certificate covers small changes to one existing circuit. An EIC covers new circuits, new consumer units and rewires.
Does minor works need notifying to building control?
Usually not, unless it is in a bathroom close to the bath or shower. Your electrician will tell you if it is notifiable.
Is a Minor Works Certificate the same as an EICR?
No. It covers the new work only. An EICR reports on the condition of the whole installation.
Need a socket or light added?
We add sockets, lights and switches and certify the work. See our electrical installations and repairs.
