A dishwasher is a modern luxury that lots of us can’t do without. So when it goes wrong, it can throw a kitchen into chaos.

If you’re considering having a plumber install a dishwasher or remove your old one, read our guide for a breakdown of all the costs involved.

How much does it cost to install a dishwasher?

The cost of dishwasher installation will depend on the type of dishwasher, whether you're replacing an existing appliance or fitting one for the first time, and whether old units need to be removed.

The average freestanding dishwasher installation cost is £65, but the final cost will depend on whether you need your old dishwasher removed and disposed of and whether you need adjustments to plumbing:

If your new dishwasher is integrated, it may also require cabinet adjustments or carpentry work, so it’s worth factoring that into your budget too. You’ll probably need a kitchen fitter or carpenter for this type of work.

Dishwasher brands and models

There are plenty of dishwasher brands and models to choose from, from basic entry-level dishwashers to smart ones that you can control with an app. Here are a few of the most popular brands and models:

How long does it take to remove and install a dishwasher?

If your plumber just needs to remove and install your dishwasher in the same location, they’ll usually complete this within 1 hour. However, if it’s a first-time installation that requires changes to your plumbing, it could take 4 hours or longer.

Does a dishwasher use the same plumbing as a washing machine?

Dishwashers and washing machines typically use the same type of plumbing. Both require a cold water feed, a wastewater outlet and a power source. In many kitchens, it’s possible to have your dishwasher and washing machine share the same waste pipe using a splitter.

Can I replace an integrated dishwasher with a freestanding one?

Yes, you can replace an integrated dishwasher with a freestanding one, but there are some things to bear in mind. Integrated models are designed to sit flush with cabinetry, while freestanding ones are typically wider and deeper, with exposed sides. You’ll need to remove the cupboard door and possibly make adjustments to the surrounding units to accommodate the new appliance. You may also be left with visible gaps where the integrated unit was fitted.

If you want a freestanding dishwasher without changing the look of your kitchen too much, consider a slimline model or a semi-integrated unit as a compromise.

How long should a dishwasher last?

A well-maintained dishwasher typically lasts 8-10 years, depending on the brand, how much you use it and the water quality in your area. Higher-end models with stainless steel interiors and advanced wash systems may last even longer. 

To maximise the lifespan of your dishwasher, make sure you clean it and descale it regularly according to the manufacturer’s advice. 

Should an electrician install a dishwasher?

In most cases, no - there’s no need for an electrician to install a dishwasher. Dishwashers come with a standard UK plug and don’t need to be hardwired. However, if you need a new plug socket for your dishwasher, then you will need an electrician to fit this for you.

Similarly, for full kitchen refits that include rewiring, an electrician should be involved in the planning and fitting.

Can I install a dishwasher myself?

If you're confident with DIY and you're replacing an old dishwasher with a like-for-like model, you might be able to install it yourself. Freestanding dishwashers are particularly straightforward to fit - just connect the cold water inlet and waste pipe and plug it in.

However, for integrated models, new installations, or if adjustments to plumbing or cabinetry are needed, it’s best to hire a professional. A poor installation could result in leaks, electrical faults or damage to your kitchen. For peace of mind, and in many cases, to keep your warranty valid, professional installation is worth the investment.

Can I move my dishwasher to a new location?

During a kitchen upgrade, you may want to switch around the layout of your kitchen. There’s no reason why you can’t move the dishwasher to a new location, but you’ll need the plumbing and electricity supply there to accommodate it.

Wherever you decide on placing the dishwasher, it will need a power source, a cold water supply and a waste pipe for when it drains. Before moving your dishwasher around, make sure that it is fully disconnected and you have had a chance to drain all of the water out of the appliance.

Luckily, when it comes to moving a dishwasher, they are not as heavy as other kitchen appliances like a washing machine or tumble dryer. The best new location for a dishwasher should still be against an external wall where possible, as this way the waste pipe can run straight out of the house.

How much will it cost to repair damaged parts on my dishwasher?

Common faults with dishwashers include not draining or tripping your electrics. While it can be easy to immediately replace your dishwasher when it goes wrong, you could save money with a repair.

Appliance repair specialists tend to charge a call-out fee of £65 to diagnose a fault with your dishwasher. A new pump may set you back £140, while a new circuit board can cost £200 or more.

Make sure you check and clean the filters, waste pipe and sprayers before you call someone out in case there’s a simple blockage causing the problem.
