Essentials of Calculating Electrical Switch Positions


Electrical socket charges in renovation quotes may seem straightforward and inexpensive at first glance. However, the final billing for these sockets can amount to several tens of thousands. Some unscrupulous companies exploit this aspect to make exorbitant profits, causing clients to overshoot their budgets drastically.


Currently, the market price for installing a single 13A socket ranges between $750 – 850. However, the method of calculating the cost of sockets isn't necessarily linear.

There are several ways in the market to compute the cost of electrical sockets:

1. Number of switches

2. Number of socket panels and lights

3. Number of electrical wire connection points

Example (1): One socket controlling one light

Calculation:

- Number of switches = 1 socket

- Socket panel and light count = 2 sockets

- Electrical wire connection points = 2 sockets

Example (2): One socket controlling two lights

Calculation:

- Number of switches = 1 socket

- Socket panel and light count = 3 sockets

- Electrical wire connection points = 3 sockets

Example (3): Two sockets controlling one light

Calculation:

- Number of switches = 2 sockets

- Socket panel and light count = 3 sockets

- Electrical wire connection points = 3 sockets

Example (4): One panel with two sockets controlling two lights

Calculation:

- Number of switches = 2 sockets

- Socket panel and light count = 3 sockets

- Electrical wire connection points = 3 sockets


Furthermore, there are various types of sockets, including double sockets, 20A sockets, broadband sockets, telephone line sockets, TV sockets, doorbell sockets, etc. Prices for different socket types can vary significantly, and the calculation method can cause a huge price fluctuation (especially if the package specifies included sockets). There isn't a standardized calculation method in the market yet. To avoid significant budgetary overshoots, DECOLAND advises clients to request contractors to specify the calculation method clearly in the quote to prevent any misunderstandings.
