How Much to Install a Dishwasher?

Considering the cost of both purchasing a dishwasher and installing one, the average cost is £270 to £2,200 in total.

This range would apply whether it be a freestanding dishwasher, built-in dishwasher, or a commercial dishwasher.

However, some dishwasher units are far more expensive, in which case you could pay closer to £1,000 or even up to £2,000 for the installation of a very high-end product.

Let's break this down...

To be more precise, a freestanding dishwasher installation is likely to cost around £270 to £2,200, with the cost reaching about £1,040 to £5,100 for a commercial dishwasher, £270 to £1,800 for an integrated dishwasher, or £270 to £820 for a slimline dishwasher.

Cost factors include the size/type of dishwasher, where exactly in the property the dishwasher is being installed, ease of access, number of tradespeople hired, and the location of your property.

Why should location matter?

In regard to the final point, this is because labour costs differ across the UK and, in turn, will shape dishwasher installation prices differently.

What are the Supply Costs of a Dishwasher Installation?

This section is especially relevant for those who want to install a dishwasher themselves, although, even if you want to hire a professional, you may still be interested in knowing the materials cost of fitting a dishwasher.

On average, a dishwasher is priced at about £200 to £400 for a given unit. However, the price of units can vary from around £150 to as much as £2,100 or maybe even more. As you can see, dishwasher prices could differ greatly.

The supply cost of a freestanding dishwasher is about £200 to £2,000, while it is around £1,000 to £5,000 for a commercial unit, £400 to £1,800 for an integrated dishwasher, or £200 to £700 for a slimline product.

What are the Additional Costs of Installing a Dishwasher?

There are many added expenses that you may incur along with having a dishwasher fitted. Let’s take a look at some common examples.

Cooker Installation

There are various types of cookers you may want to have installed along with your dishwasher. These prices include the cost of purchasing a cooker and that of installing one.

New Kitchen

You may also be interested in having an entirely new kitchen installed. Refurbishing a kitchen is a fantastic way to provide your home with a whole new lease of life. The average prices for such an instalment are as follows:

Tradesmen Costs for a Dishwasher Installation

A smaller component of the overall cost, alongside that of the supply cost, any added expenses, and of course, if applicable, any waste removal expenses, is that of labour cost.

On average, the dishwasher price of labour will range from £40 to £100, depending on where you live and how long the job takes.

How Long Does It Take to Install a Dishwasher?

On average, it takes about an hour to fit a dishwasher, although in some cases, it could take around 1.5 hours or up to two hours. Generally speaking, an hour’s work should be expected.

Time-affecting factors include the size/type of the dishwasher, ease of access, whether an old dishwasher is being removed first, and the number of tradespeople hired. Notably, though, it’s quite likely only one contractor will take on the job.

Types of Dishwashers

There are various types of dishwashers on the market. It’s important that you choose the right one for you and your property.

Freestanding Dishwasher

These standalone dishwashers can be installed wherever you want on your property so long as it is safe to do so and it has access to drainage and water.

freestanding dishwasher

Freestanding dishwashers are quite similar to integrated dishwashers, such as in how they can be hooked up to waste and water supply. However, they have unique sides along with a top cover allowing them to be installed anywhere with the space and safety to allow it.

These dishwashers often cost about £200 to £2,000. If you’re on a budget, this is usually the best type to go with.


  • More freedom in choosing where it can be situated
  • It tends to be easier to diagnose issues with these dishwashers


  • Could end up taking more time to pick the right spot
  • It can be louder than many other dishwasher options

Commercial Dishwasher

These dishwashers are generally employed for commercial kitchens and tend to offer more power while being larger too.

Installing a commercial dishwasher is usually quite similar in terms of the price (excluding the actual supply cost) and process as with a residential dishwasher. They tend to be priced around £1,000 to £5,000.


  • High-end dishwashers
  • Perfect for a restaurant kitchen


  • The actual unit can be quite expensive

Integrated Dishwasher

If you’re interested in a customised unit, then an integrated dishwasher may be the best way to go. Of course, more work will probably be needed to fit it in place than would be needed with a freestanding dishwasher.

Integrated dishwashers usually lack a top, sides, and front cover. They generally cost about £200 to £1,700.


  • Good for customisation


  • Usually more expensive than freestanding dishwashers
  • Less choice as to where they can be installed over freestanding units

Slimline Dishwasher

As you may guess, slimline dishwashers are those that are quite slim in size and are well-suited to small properties or/and those with limited room.

They are usually cheaper than any of the other types discussed here at about £200 to £700 on average per unit. Interestingly, there are small dishwashers out there on wheels that are even portable! So, there are quite a few options to consider here.

However, one of the obvious downsides of slimline dishwashers is, well, that they are small and thus have a more limited capacity. Another type of small dishwasher worth considering is a countertop dishwasher.


  • Relatively cheap
  • Great for tight spaces


  • Less capacity

Benefits of Updating Your Dishwasher

There are obviously many notable advantages to installing a new dishwasher. Here are some examples.

Improved Quality

Of course, upgrading to a new dishwasher will not only have its benefits, considering that an older unit will have lower quality than when it was initially purchased, and a brand-new dishwasher is also likely to bring higher quality as a new product also.

Can Resolve Issues

Some problems may have emerged over the course of your existing dishwasher’s lifespan, so buying a new one can prove a great solution, whether it be that your current machine is not cleaning completely effectively, it’s making strange noises, or water remains following a wash.

How Much Does It Cost to Remove a Dishwasher?

You may need to simply have a dishwasher removed as you wish to install a new one later or you’ve already installed a new one elsewhere in your property. It should cost about £100 to £200, including waste removal expenses.

Q: How do you clean a dishwasher?

A: One common approach involves grabbing a bowl (one that is safe to put in the dishwasher) and filling it with a cup of white vinegar.

Next, put it at the bottom of an empty dishwasher and run a hot water cycle. This will allow the vinegar to get to work, breaking down food bits, residue, grease, etc.

Q: How do you connect a dishwasher?

A: This will vary greatly from product to product, and if in any doubt, you should hire a professional. Broadly speaking, the installation area should be prepared before the dishwasher (once the old one is removed, if applicable) can be connected to a power source.

Next, the dishwasher can be fitted and connected to the existing water supply.

The sink or a water outlet may be used to drain. The connections should then be checked, such as for leaks, before the machine may be plugged in, and a short water cycle should be used to see that it works correctly.

Once it all looks good, place the machine against the wall, and it’s good to go. Again, this process may differ depending on the specific unit.

Q: How long should a dishwasher last?

A: On average, dishwashers tend to last around a decade.

Q: What are common signs that a dishwasher should be replaced?

A: Examples include that it is rusting, the door is not locking correctly, water is leaking onto the floor, the dishes are coming out dirty or spotty, water is still present after a wash, or it is beginning to crack.

There are quite a few other signs that may be present also. The more that you notice, the more evident it is that your dishwasher is on the way out.

Q: What is the most common issue I may find with a dishwasher?

A: You’re most likely to find a defective water inlet valve before you notice other issues.
