How Much to Install a Dishwasher?

Let's get straight to it:

How much does it cost to install a dishwasher in the UK?

The average cost of installing a dishwasher will depend on the type being fitted. A regular freestanding dishwasher would have a total installation cost (labour and supply costs) of about £350 to £700.

The integrated dishwasher installation cost would be around £550 to £1,100 with the cost of fitting a slimline option being approximately £300 to £450. For a more expensive choice, installing a commercial dishwasher would require a budget of about £2,050 to £4,100.

The cost would depend not only on the size and type of dishwasher but even the material used, the brand, ease of access to the work area and whereabouts in the UK you live. Your location is especially important as labour prices differ across the different parts of the UK.

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.

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.

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.

How Much Does Dishwasher Installation Cost?

Now, let's take a look at labour costs and timescales.

The labour prices involved in fitting a dishwasher are part of the overall cost of such work but exclude the supply costs.

The cost of labour, regardless of the type of dishwasher, should fall in the range of £50 to £100.

In terms of the duration of the work, it would usually take an hour or two, but it would depend on the ease of access to the work area and the complexity of the installation. The cost of labour would be affected by these factors, as well as your specific location.

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.

What Impacts Dishwasher Installation Costs?

As you’ve seen, there are various cost-affecting factors involved in fitting a dishwasher. In this section, we’ll break these down in further detail.

Type and Size

The most important cost-affecting factor of 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. The exact size of the dishwasher could also impact the standalone cost.

Material

Dishwashers tend to be made largely of stainless steel and plastic. Some may be more metallic-based than others. In this case, they may be more expensive than dishwashers that contain more plastic, but in general, the size/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. If they are charging by the hour, then this could be the difference between a labourer billing you for one hour of labour than two, which would be a difference of about £50.

Location in the UK

Where you are located is also important to take on board given that dishwasher installation prices in terms of the cost of labour differ across the UK. Most homeowners will find that labour prices are above the UK average in the southeast (London is quite notorious for high pricing).

However, the north of England, Scotland and Northern Ireland usually have below-average labour costs.

This cost factor would not make a huge overall difference to your pricing since most of the cost of a dishwasher installation is down to the standalone cost of the dishwasher itself, whereas the cost of labour would probably make up somewhere between 5% and 20% of your total bill. This would depend on the type of dishwasher you’re installing.

What's Involved in Installing a Dishwasher?

Fitting a dishwasher looks simple, but there’s water, waste 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 an 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 waste — 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.
• 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.

Can I Install a Dishwasher Myself?

If you’re simply swapping an old machine for a new one in the same spot, then yes – most confident DIYers can manage it.

As long as there’s already a socket handy, an isolation valve on the water feed, and a spare spigot on the sink trap, it’s mostly a case of connecting things up.

Turn off the water and power, hook up the inlet and waste hoses without kinking them, and make sure the machine is level so the door shuts properly.

Where it gets fiddly is if you’re putting a dishwasher somewhere it hasn’t been before. No water feed, no waste pipe, or no electrics in the right place? That’s not really a DIY job.

Adding pipework, adjusting traps, or wiring in a fused spur needs a qualified tradesperson. It keeps everything safe, up to regs, and saves you a potential mess later on.

DIY checks to bear in mind

• Turn off and test: isolate water at the valve and electrics at the consumer unit before you start.
• Use the high-loop: route the waste hose up under the worktop to prevent backflow.
• No buried plugs: the socket or switch must be accessible (not trapped behind the machine).
• Commission properly: open the valves, check every joint, and run a hot empty cycle to confirm no leaks.

When to call a pro

• No isolation valve/spare trap spigot.
• Need to extend or reroute pipework or drainage.
• No safe, accessible electrical supply (requires a switched fused spur).
• Integrated door alignment or plinth modifications you’re not comfortable with.

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 sswitched fused connection unit (double-pole) above the worktop, or a socket in the adjacent unit rather than hidden out of reach.

Hiring Contractors to Install a Dishwasher: Checklist

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 waste and disposal included? Check they’ll remove the packaging and old machine, 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.
