Installing a powerpoint to external wall, which is double brick cavity wall, is always easier and cheaper. We drill a hole in the inner brick using the cavity to pull the cable up to roof space to join it to an existing power circuit. We always recess the power point to wall and do not use a mounting block, which can look ugly sticking out of the wall.

Installing a powerpoint to internal wall, which is single (non-cavity) wall requires more work and involves more materials, thus installation to internal walls is a bit more expensive and you can see that our prices are $30 more than for the external cavity walls.

There are two options for internal walls:

• Chasing the cable into the wall – This is very neat just like on the external wall (no cable or conduit are visible and the power point is recessed), however, plastering and painting will be required and are not included in the installation price. This is the ideal solution during renovation prior to painting.

• Surface mounted ducting – This is not as neat looking as chasing but the benefit is that it will not require plastering and painting. For this solution, we mount white square ducting as an enclosure for the cable. Note that the power point cannot be recessed and we need to use a small mounting block. To minimise the visual impact of this, look for opportunities to position the new power point where there is something on the other side of wall that can hide the surface mounting ducting such as a wardrobe.

All electrical work is carried out by licensed electricians and a Safety Certificate is issued after installation, so that you know that all work is fully licensed and compliant.
