How Much Does It Cost to Install a Dishwasher?
£100 – £250
per job
Installing a dishwasher costs £100 to £250 when a plumber is used, though appliance retailers often offer installation for less. The price depends on whether a cold water supply and waste outlet are already in place. A like-for-like replacement where connections already exist is the cheapest scenario.

Prices vary by region, property type and tradesperson. Always get at least two quotes.
What affects the price?
Existing connections - if a supply valve and waste outlet are already in place, installation is quick and cheap
New supply run - routing a new cold supply from under the sink adds £50-£100 in labour and materials
Integrated vs freestanding - integrated dishwashers require door panel alignment and take longer to install correctly
Old appliance removal - most plumbers will dispose of your old machine; check whether this is included or charged extra
Labour vs materials
A straightforward dishwasher connection takes 30-60 minutes. Labour accounts for the majority of the cost; materials such as hoses and isolation valves add £10-£30.
