All kitchens and bathrooms require power and water.

So it's likely that you'll be liaising with an electrician and plumber on just about every installation project you do, with the exception maybe of very small renovation jobs.

Some projects incorporate other services as well, such as phone lines and air conditioning.

In these cases there may be other technicians you have to work with when you plan and carry out an installation.

Set out below are the main people involved in installing these services.

The plumber will rough in the water pipes before the wall lining goes on and run the waste pipes through the floor.

Once the cabinets have been installed and tiling or other wall linings are finished, they will come back to connect up the taps, sinks, toilets and other plumbing fixtures.

Like the plumber, the electrician will also come on-site before and after the cabinetry installation. They will rough in the wiring first, and then return later to connect up the fittings and appliances.

These may include power points, lights, exhaust fans, ovens, cook tops and air conditioners.

Air conditioning technician

Ducted air conditioning systems use large ducts to carry warmed or cooled air around the house. In a split system the technician might install the warm air ducts under the floor and the cool air ducts above the ceiling.

Outlets can be in the ceiling, floor or wall, depending on the system and available space.

Cabling contractor

Phone lines and data cables need to be installed by a contractor approved by the service provider.

Where possible, contractors prefer to run the cabling before the internal wall linings are installed. They can then come back to connect up the phone points or data sockets.

The different trades often have their own specialised plans showing the services they are providing. Below is an electrical plan for a kitchen and bathroom.

See if you can answer the following questions:

  1. How many double power points are in the bathroom?

  2. How many single power points are in the kitchen?

  3. How many ceiling lights are in the kitchen?
