Basic dishwasher installation labour in the UK typically costs £50–£100, since most jobs take just 1–2 hours and plumbers often charge a fixed fitting fee rather than a day rate. Including the appliance itself, total costs generally run £340–£800 for a freestanding dishwasher, £440–£1,100 for an integrated model, and £240–£700 for a slimline unit. Integrated dishwashers cost more overall because they require additional carpentry to fit into cabinetry, while freestanding models are the cheapest and most straightforward to install.

Estimates vary meaningfully between sources depending on region, appliance quality, and whether an old unit needs removing, so treat these as a general planning range rather than an exact quote.
Freestanding Dishwashers
Freestanding dishwashers are standalone units that can be positioned anywhere in the home with access to water and drainage, and they come with their own sides and top cover so they don’t need to match surrounding cabinetry. This is what makes them the cheapest and quickest option to install — average installation labour sits around £65–£100, with most jobs completed in 1–2 hours. The dishwasher unit itself typically costs £300–£600, with some estimates putting the higher end of the range as far as £2,000 for premium models.
Pros: more freedom in where you place it, and generally easier to diagnose issues since the unit isn’t built into cabinetry. Cons: doesn’t blend into your kitchen’s look, and can be slightly louder than integrated alternatives in some cases.
Integrated Dishwashers
Integrated dishwashers are built into your kitchen cabinetry and typically arrive with no front cover, top, or sides, so you can add your own panel to match your existing cabinets. This customisation is the main appeal, but it also drives up the cost: integrated dishwashers require additional carpentry work to fit them into your kitchen and achieve a consistent look, and this extra labour can add £100–£300 on top of a straightforward freestanding installation. The dishwasher unit itself typically supplies for £500–£1,800, and total installed cost (appliance plus labour) generally lands between £440 and £1,100.
Pros: blends seamlessly with your kitchen design. Cons: more expensive overall, and less flexible in terms of where you can fit one, since the opening needs to match the appliance’s exact dimensions.
Slimline Dishwashers
Slimline dishwashers are a narrower alternative to full-size models, well suited to smaller kitchens. Installation costs are broadly similar to freestanding units, with the appliance itself typically priced £200–£700 and total installed cost generally in the £240–£700 range.
What Affects Dishwasher Installation Cost?
- New installation vs. replacement. Replacing an existing dishwasher is generally cheaper than a first-time installation, since the plumbing and drainage connections are typically already in place.
- Plumbing modifications. If shut-off valves, a new water supply line, or pipework need to be added or altered, this can add a further £100–£400 to the total cost.
- Carpentry for integrated models. Custom cabinet adjustments and precise alignment work required for integrated units add £100–£300 or more compared to a freestanding installation.
- Old unit removal and disposal. If your existing dishwasher needs to be taken out and disposed of, this adds to the overall job cost and time.
- Regional labour rates. Labour costs vary across the UK, which is one of the main reasons quotes for what sounds like the same job can differ meaningfully by location.
- Electrical work. If the dishwasher needs a new dedicated electrical connection rather than plugging into an existing outlet, this adds both cost and time.
How Long Does Dishwasher Installation Take?
Most dishwasher installation jobs take around 1 to 2 hours for a straightforward replacement with existing plumbing already in place. This is why labour is commonly charged as a fixed fitting fee or minimum call-out charge rather than a full day rate. Integrated installations requiring cabinet adjustments or new plumbing connections will generally take longer and cost more accordingly.
Do You Need a Plumber to Install a Dishwasher?
For a straightforward replacement with existing water and drainage connections in place, many people are comfortable installing a dishwasher themselves. However, a licensed professional is generally recommended, and sometimes required, if:
- The property has no existing water supply or drainage connection for a dishwasher, requiring new pipework.
- The installation needs a new electrical connection rather than an existing plug socket.
- You’re installing an integrated model that requires carpentry work to fit cabinetry panels correctly.
- You want the reassurance of a professional job for warranty or insurance purposes.
Frequently Asked Questions
How much does it cost to install a dishwasher in the UK?
Basic labour typically costs £50–£100 for a straightforward job, while total cost including the appliance generally ranges from £340–£800 for freestanding models up to £440–£1,100 for integrated units, depending on the specific dishwasher and any additional plumbing or carpentry work needed.
Is it cheaper to install a freestanding or integrated dishwasher?
Freestanding is generally cheaper, since it doesn’t require the additional carpentry work needed to fit an integrated model into kitchen cabinetry, which can add £100–£300 or more to the labour cost alone.
How long does it take to install a dishwasher?
Most installations take 1 to 2 hours for a standard replacement with existing plumbing already in place. Integrated installations or jobs requiring new plumbing or electrical work will typically take longer.
Do I need a plumber to install a dishwasher?
Not always — a straightforward replacement with existing connections is manageable for some homeowners. A licensed plumber or electrician is recommended if new water, drainage, or electrical connections are needed, or if you want professional assurance for warranty purposes.
Why is integrated dishwasher installation more expensive than freestanding?
Integrated dishwashers require precise carpentry work and cabinet panel fitting to blend seamlessly with your kitchen, which adds meaningful labour time and cost compared to a freestanding unit that arrives with its own sides and top cover.
What’s the average total cost for a dishwasher including installation?
Combining the appliance and installation labour, most UK homeowners can expect to pay somewhere between £350 and £1,100 depending on dishwasher type, with slimline and freestanding models generally at the lower end and integrated or commercial units at the higher end.
Conclusion
Dishwasher installation costs in the UK for 2026 come down to two main factors: which type of dishwasher you’re installing, and how much extra work — plumbing, carpentry, or old-unit removal — the specific job requires. Freestanding models remain the cheapest and quickest option for straightforward replacements, while integrated dishwashers cost more due to the additional carpentry needed to fit them properly into your kitchen. Get a few quotes from local tradespeople before committing, since regional labour rates and the specific complexity of your setup can shift the final price meaningfully from these general ranges.
