Dishwasher installation cost guide

The dishwasher is a revolutionary addition to any kitchen. Instead of eating into your precious time, dirty dishes are cleaned with little effort. But what is the average dishwasher installation cost and how long does it take to get up and running?

Whether you’re getting a dishwasher as part of a new kitchen or replacing an old appliance,  there’s no doubt that the convenience is worth the upfront cost – even a budget model can make all the difference.

While homeowners well accustomed to plumbing may have the confidence to go it alone, we recommend hiring a professional to ensure installation is carried out correctly.

Below, we’ve set out the average dishwasher installation cost and what the job will include, so that you can plan your finances in advance.

Average dishwasher installation cost = £55 - £100

How is a dishwasher installed?

Having measured your space and conducted some research on dishwasher costs and features, you’ve settled on your choice and made the purchase. The next step is to get it set up.

Installing your own dishwasher can be difficult at best and dangerous at worst. Though not impossible, it’s a task you should only undertake with the right experience, tools and a great deal of research.

That said, even the most straightforward installations may require help from the professionals. Just in case, we recommend factoring this into your calculations when budgeting for dishwasher installation costs.

The standard dishwasher installation process is detailed below, though the exact instructions will vary depending on which model you own and whether you need to remove an old appliance.

The new appliance will be unboxed and checked for damage. A suitable location will be identified (this will typically be against an exterior wall where possible to prevent a waste pipe from running on the inside of your wall.)

  1. Existing electrical and plumbing connections will be inspected to ensure they are safe and suitable for your new dishwasher.
  2. Water will be turned off at the mains ahead of installation
  3. The dishwasher will be connected to the mains water supply within 1.5 metres of the appliance and connected to an electrical socket.
  4. The waste hose will be connected to a down-pipe or extended waste connection
  5. The appliance will be tested for leaks and functionality
  6. The water and power will be turned back on once a technician has fitted, installed and tested your new dishwasher. If you have requested removal of an old appliance, this will happen after installation.

How long does it take to install a dishwasher?

Dishwasher Installation cost

Dishwasher installation is usually completed within a couple of hours. With a number of variables influencing the time taken to complete the job, however, dishwasher installation prices can be unpredictable.

Providing the measurements of the dishwasher are correct, the space does not need to be altered and you already have an accessible electrical outlet and drain, your dishwasher shouldn’t take much longer than an hour to install at an average price of £55+ VAT.

If you need an old dishwasher to be removed first, you can add an hour on in installation time.

Similarly, any structural changes or alterations to electrics, plumbing, flooring or kitchen counters will add on time and, therefore, the price to install a dishwasher. 

For more complex installations, the cost is more likely to come to an average of  £100+ VAT.

This is often influenced by the type of dishwasher.

Different types of dishwasher

Cost-effective, efficient, quiet and quick: these are the qualities we look for when buying a new dishwasher – whether as a one-off or as part of a wider kitchen renovation project.

Naturally, the total dishwasher installation cost will vary depending on the requirements and work that needs to be done to get your new appliance up and running.

Below, we’ve outlined the three different types of dishwasher along with the costs associated:

Freestanding dishwasher cost

Freestanding dishwashers are standalone units that can be positioned anywhere in the home where there is access to water and drainage.

Though they connect to water supply and waste just as integrated dishwashers, they come with their own sides and a top cover so you can place it anywhere it fits.

The average cost to install a freestanding dishwasher is £77.50.

Integrated dishwasher installation cost

An integrated dishwasher is a popular choice for those seeking more room for customisation. They typically arrive with no front cover, top or sides, allowing you to add your own to match your kitchen cabinets.

Integrated dishwashers generally require additional carpentry work to build them into your kitchen and achieve consistency.

On average, an integrated dishwasher will cost £77.50 to install correctly.

Commercial dishwasher installation cost

Designed to be used in commercial kitchens, dishwashers of this type are generally larger and more powerful than residential units to accommodate for a bigger load.

Commercial dishwashers vary in size and style, but the process of installation shouldn’t differ much from residential appliances.

For a straightforward installation of a commercial dishwasher, the average price is £77.50.

Additional costs to consider

A new dishwasher can be transformational, helping to save water and crucially, time spent cleaning dishes. Depending on the specification and requirements, you may find there are additional costs associated with the installation.

Simply put, the more of a technician’s time is required for the job, the higher the cost to install a dishwasher. In some cases, plumbing and electrical modifications will need to be made in order to ensure a safe installation.

In any case, it’s always wise to get a full understanding of the cost to install your dishwasher ahead of purchase and ask a tradesperson for a breakdown of their quote.

The importance of installing a dishwasher correctly

A dishwasher is an investment: to get the most out of it, you should have a licensed technician undertake the work. In our experience, the price to install a dishwasher is worth paying to prevent problems further down the line.

When installed correctly, you reduce the risk of leaks and water damage that can occur when a dishwasher isn’t properly fitted. What’s more, a professional can advise on the best location if you aren’t sure.

Contrary to popular belief, modern dishwashers also use less water than hand-washing and are therefore considered the more eco-friendly option.

Since they heat water internally rather than prompting your boiler to produce hot water, most modern dishwashers save energy on each use.

Hiring a professional dishwasher technician to fit your new appliance can allow you to optimise your water usage and give you the peace of mind that your dishwasher has been installed correctly.

Dishwasher installation cost breakdown

  • Dishwasher installation is a multi-step process with more than a few pitfalls along the way.
