How Much Does It Cost to Have a Dishwasher Installed?
Adding or upgrading a dishwasher in your kitchen is one of the easiest ways to make life a little bit easier. Less time doing dishes, more time enjoying what really matters.
Installing a dishwasher can be a straightforward job if it’s a simple replacement.
Wondering, how much does it cost to have a dishwasher installed? Let’s check out what the different installations might cost.
What Goes Into the Cost of Dishwasher Installation?
When you're pricing up a dishwasher install, it's not always just about connecting a few pipes and plugging it in. Here's what we typically look at:
Plumbing and drainage access:
If you're replacing an old unit, it's usually straightforward. But if it's your first dishwasher, we may need to install new pipework or modify existing plumbing.
Electrical access:
A licensed electrician may need to install or move a power point, depending on your kitchen layout.
Cabinet modifications:
If your cabinetry needs to be adjusted to fit the dishwasher, this could add to the cost. We’ll always talk through these options with you first.
Type of dishwasher:Freestanding units are generally quicker to install. Integrated or drawer dishwashers can take a bit longer due to the custom fitting involved.
