How Much to Install a Dishwasher?

So, how much does it cost to install a dishwasher in the UK?

The cost for a standard dishwasher installation is typically between £50 and £100.

As most dishwasher installation jobs take around 1 to 2 hours, labour is often charged as a minimum call-out or fixed fitting fee rather than a full day rate.

A standard dishwasher installation is where you already have all the necessary plumbing and electrics to install the dishwasher, either because you're replacing one that's already there, or fitting one into a space already designed for a dishwasher.

More complex installations would see this cost increase, with fitting integrated dishwashers usually costing slightly more, and brand-new installations requiring electrics and plumbing, or relocating an existing dishwasher, costing significantly more.

Dishwasher Installation Prices

The table below shows how typical dishwasher installation costs can vary depending on how complex the required work is going to be.

How Long Does Dishwasher Installation Take?

For a standard dishwasher installation costing between £50 and £100, you should expect it to usually take around 1 to 2 hours.

This straightforward installation usually includes:

• Basic dishwasher installation.
• Connecting the new dishwasher to existing water supply, waste pipes and power services.
• Positioning and securing the dishwasher.
• Testing the appliance once installed.

If anything more than a standard dishwasher installation is required, this will start to affect how long it takes for you to get your dishwasher installed.

The table below outlines the typical timescales for dishwasher installation processes of varying complexity.

How Much Does a New Dishwasher Cost?

We'll now take a look at the standalone costs involved in installing a dishwasher. These costs would apply if you were to purchase directly from a retailer yourself.

We'll also outline the pros and cons of each option, so that you can get a sense of what option is best in your circumstances.

If you're replacing an existing dishwasher, it may be worth comparing dishwasher repair costs with the overall cost of a replacement, as that might be a more cost-effective option.

Freestanding Dishwasher Cost

Freestanding dishwashers are standalone floor-standing units that slide into a gap in your kitchen. (They’re different from countertop or “portable” models.) These dishwashers can be fitted with relative ease and can be installed wherever there is access to water and drainage.

These dishwashers are also relatively cheap. In fact, the standalone cost of a freestanding dishwasher is around £300 to £600.

Integrated Dishwasher Cost

A built-in or integrated dishwasher is a popular alternative to freestanding models. Integrated dishwashers are a good choice if you’re interested in customisation.

However, they do tend to be more costly than freestanding dishwashers, and there is less flexibility in terms of where you can fit one.

Integrated dishwashers come with a supply cost of around £500 to £1,000.

Note: “Top-control” refers to controls on the door’s top edge (often hidden on fully integrated machines). “Front-control” models show the controls on the door front.

Slimline Dishwasher Cost

For smaller spaces/homes, a slimline dishwasher may be a good fit.

These dishwashers are slimmer and tend to be relatively inexpensive at approximately £250 to £350. The downside is that they provide a lower capacity.

Commercial Dishwasher Cost

A commercial dishwasher is not the right type for a regular domestic environment. Instead, they are perfect for restaurant kitchens.

These high-end appliances are designed with a large capacity; however, they are fairly expensive, with a supply cost of around £2,000 to £4,000.

In the table below, we've put the essential information side-by-side so you can get a quick look at what the cost of a standard installation of dishwashers of different types would be for you in 2026.

What Impacts Dishwasher Installation Costs?

The average dishwasher installation cost will vary depending on several factors. In this section, we'll break these down in further detail.

• Type and Size — The most cost-affecting factor in a dishwasher installation would be the size and type of dishwasher. While a slimline dishwasher has a supply cost of around £250 to £350, the standalone price of a commercial dishwasher would be somewhere in the thousands of pounds.
• New Install vs Swap — Replacing an old dishwasher in the same spot keeps costs down, as the plumbing connections and electrical supply are already in place. Installing a new appliance somewhere new may require additional electrical work and pipework, which adds to the overall dishwasher installation cost.
• Integrated Fitting — Fitting an integrated dishwasher for the first time may require modifications to your kitchen cabinets. A front cover panel will also need to be fitted to match your existing units.
• Brand and Material — Dishwashers tend to be made largely of stainless steel and plastic, and some may be more expensive than others. In general, however, the size and type of dishwasher would be more important for the cost.
• Ease of Access — The easier a contractor can access the workspace for installing your dishwasher, the sooner they'll be able to complete the work. This could be the difference between a labourer billing you for one hour of labour or two, which would be a difference of about £50.
• Location in the UK — Dishwasher installation prices in terms of the cost of labour differ across the UK. Most people will find that labour costs are above the UK average in the South East, while the North of England, Scotland and Northern Ireland usually have below-average labour costs.
• Old Appliance Removal — Disposing of an old dishwasher isn't always included in quotes, and can add to your overall dishwasher installation costs. Confirm upfront whether the removal of the old appliance is included to avoid any unexpected additional costs.

What's Involved in Installing a Dishwasher?

Fitting a dishwasher looks simple, but there’s water, drainage and electrics in a tight space. It's incredibly easy for something to go wrong, which is why most people hire a professional to handle this job.

Submit a few details on MyJobQuote and you'll get up to three quotes from plumbers near you that you can compare. Quotes are free and there's no obligation to go ahead.

Here's what's involved at each point of a dishwasher installation.

Before the Job Starts

• Survey and position — Measure the aperture (600 mm for standard, 450 mm for slimline), check door swing, plinth clearance and that water, waste and an accessible socket/switch are close by.
• Services and isolation — Turn off water/power. Confirm or fit isolation valves, a spare waste spigot on the sink trap, and a safe electrical point (socket or switched fused spur that’s accessible).
• Prep the space — Remove the old unit if needed, protect floors, plan hose routes, and set the feet ready for levelling under the worktop.

During the Job

• Connect water — Fit/secure the inlet hose to the isolation valve (often cold feed). Add a Y-piece or non-return valve if required by the model.
• Connect the drain — Cut the blank on the trap spigot, attach the waste hose, and form a high loop (or use an air-gap where specified) to prevent backflow.
• Make the electrical connection — Plug into an accessible socket or connect via a switched fused connection unit (double-pole) — avoid trailing extension leads or sockets buried behind the machine.
• Slide in and level — Route hoses neatly, slide the unit into place, then level it side-to-side and front-to-back so the door seals properly. For integrated models, fix the brackets and align the kitchen door.
• Commission — Turn on water and power, run a rinse/empty cycle, and check every joint/trap for leaks.

After the Job

• Final checks — Re-check for drips, ensure hoses aren’t kinked, and confirm racks clear the plinth and the door closes flush.
• Clear away waste — Your contractor will clear away all the waste and packaging and, if it was agreed as part of your quote, remove and properly dispose of your old dishwasher if required.
• Handover — Set salt/rinse-aid, show you filter cleaning and run the first hot empty wash. If new electrics were installed, provide the appropriate electrical paperwork.

Building Regulations and Planning Permission for Dishwasher Installations

• Like-for-like replacement: Using existing plumbing and an existing socket is usually fine with no Building Control notification — just make sure it still meets Building Regs (safe electrics, correct waste, backflow protection).
• New or altered electrics: Adding a new circuit from the consumer unit is notifiable (use a Part P-registered electrician or notify Building Control). Extending an existing kitchen circuit is normally not notifiable in England but can be in Wales; all work must comply with BS 7671.
• Plumbing: Follow Water Supply (Water Fittings) Regulations — fit an isolation valve on the feed and connect the waste to a suitable trap/standpipe to prevent backflow. Building Control is not usually involved.
• Planning permission: Not needed for internal appliance installs. Exceptions include listed buildings or if the job is tied to wider building works that do require consent.
• Socket location: Keep it accessible — typically a switched fused connection unit (double-pole) above the worktop, or a socket in the adjacent unit rather than hidden out of reach.

Checklist: Finding a Dishwasher Installer Near You

Getting the right person in will make your dishwasher installation job so much easier. Because do you really want leaks or sparks? Use this quick checklist before you book.

• Do they have relevant experience? Look for recent, like-for-like installs (integrated, slimline, awkward alcoves). Ask for photos or examples on their MyJobQuote profile.
• Are they Part P / electrics covered? If a new spur or circuit is needed, confirm they’ll use a Part P-registered electrician and provide the right electrical paperwork.
• What about public liability insurance? Make sure they’re insured — it’s peace of mind if anything goes wrong.
• Do they itemise quotes? The quote should make obvious labour, small parts (valves, traps, fittings), any electrical work, and disposal of the old appliance (WEEE).
• Is disposal of the old dishwasher included? Check they’ll remove the packaging and old appliance, or give you a price if not included.
• Access and services: Confirm there’s an accessible socket/switch, isolation valve on the water feed, and a spare trap spigot — or that they’ll fit what’s missing.
• What will the timescale be? A straight swap is usually 1–2 hours. New pipework/electrics will take longer — get this noted on the quote.
• Do they give guarantees and aftercare? Ask what’s covered if there’s a leak or alignment issue in the first few weeks.
• Do they have reviews you can trust? Have a skim through homeowner feedback on MyJobQuote to see how they handle hiccups.
• What are their payment terms? Agree when and how you’ll pay (e.g., after commissioning and leak checks). Avoid big upfront payments for small domestic jobs.

Tip: Get at least three plumber quotes near you so you can compare like-for-like. With MyJobQuote, you can post the job once and hear back from local, vetted trades quickly.
