It’s not recommended to daisy-chain extension leads as it may compromise safety and reduce efficiency, such as:

1. Overheating risk:

Each extension lead adds resistance to the electrical circuit, which can generate excess heat, especially when used with high-power appliances like vacuum cleaners. Over time, this can lead to overheating, increasing the risk of electrical fires.

2. Voltage drop and reduced efficiency:

Longer cable runs created by daisy-chaining can cause a voltage drop. This means the electrical current may not be sufficient to power your device effectively, leading to reduced performance or potential damage to the appliance.

3. Exceeding Amp rating:

When multiple extension leads are connected, it becomes harder to monitor the total electrical load. Exceeding the amp rating of a single cable can overload it, causing damage to the wires, plugs, or even the connected appliance.

4. Increased tripping hazard:

Daisy-chaining leads can create a messy setup with tangled or excess cables, posing a physical hazard that can cause trips, falls, or damage to the leads themselves.

5. Connection weakness:

Each connection point between two leads is a potential weak spot, which may not be as secure as a single, continuous cable. These weak points can lead to accidental disconnections, sparks, or poor conductivity.
