The Bosch Series 4 SPV4EMX17G is the strongest all-round choice for a fully integrated 45cm dishwasher, with a B energy rating and water consumption of 8.7 litres per Eco cycle. For a lower-cost option, the Beko DIS15020 offers 10 place settings and five programmes. The Sharp QW-NS14I49EX-EN is another value option, with a 4.7/5 customer rating from 159 AO reviews.

Prices are retailer listings checked on 8 September 2026 and can differ for the same model. For example, the Beko DIS15020 is listed at £249 by John Lewis, while AO lists it at £340, or £378 before the AO member discount. Consider the appliance price, delivery, removal and fitting charges together.
In the UK, a slimline integrated dishwasher is designed for a housing about 45cm wide, compared with around 60cm for a full-size machine. The category is standard, but exact appliance dimensions vary. Fully integrated models commonly measure approximately 81.5–82cm high, 44.6–44.8cm wide and 55–55.5cm deep.
That means “45cm dishwasher” is a nominal category rather than an instruction that every appliance has exactly 450mm of width. The models listed here range from 44.6cm to 45cm wide. Height and depth are also important when replacing an existing machine, particularly where the plinth, worktop or adjacent units restrict movement.
A 40cm integrated slimline dishwasher is not the normal UK format described by the manufacturer and buying-guide sources. The established integrated slimline size is approximately 45cm, while a full-size integrated dishwasher is generally around 60cm wide. The listed integrated appliances therefore suit a narrow 45cm housing, not a 30cm or 40cm opening.
The Beko DIS15020 is the clearest budget pick among the models with detailed specifications. John Lewis lists it at £249. It has 10 place settings, five programmes, an E energy rating and a 49dB noise output, with dimensions of 81.8cm high, 44.8cm wide and 55cm deep. Beko specifies a cold-water supply, water pressure of 3–10 bar, front-adjustable feet and a self-adjusting furniture-door hinge system.
The Sharp QW-NS14I49EX-EN is listed by AO at £289, or £285 for AO members. It also has 10 place settings and an E energy rating, and AO gives it a 4.7/5 rating from 159 reviews. Its dimensions are 82 × 45 × 55cm.
Other budget models listed by Need a New Dishwasher include the Candy CI0C7SB0FA-80 and Beko BDIS16030 from £299, the Statesman BDW4509 from £270, the Hisense HV523E15UK from £269 and the Candy CDIH-2L952-80 from £249. The same guide lists the ElectriQ EQDWINT45 from £239 and the Cookology CBID450 from £269.99. It places these products in a budget category below £350 and states that 45cm built-in models generally offer nine or 10 place settings.
The Bosch Series 4 SPV4EMX17G is the Bosch model to choose when energy performance and features matter more than the lowest purchase price. Bosch lists it at £599, with a B energy rating, water consumption of 8.7 litres per Eco cycle and dimensions of 815 × 448 × 550mm. It has a 4.7/5 rating from 61 reviews on Bosch’s site.
Bosch also lists the Series 2 SPV2HKX02G as a fully integrated 45cm dishwasher at £499. Its stated dimensions are 815mm high, 448mm wide and 550mm deep, with 10 place settings, a 4.5/5 rating from 70 reviews and a listed noise level of 46dB. This makes it a useful alternative if capacity and quieter operation matter more than the Series 4’s B energy rating.
Currys lists the Bosch Series 4 SPS4HMW14G as a 45cm-wide freestanding slimline dishwasher. The SPV4EMX17G, by contrast, is a 44.8cm-wide fully integrated slimline dishwasher. This distinction matters: a freestanding slimline dishwasher has its own visible exterior, whereas a fully integrated model is intended for a matching furniture door.
For most slimline integrated buyers, nine or 10 place settings is the useful capacity range. The Beko DIS15020 and Sharp QW-NS14I49EX-EN each have 10 place settings. The Hotpoint HP2IE10CS80UK is also specified with 10 place settings, while the Smeg DI4522 has nine. The CDA CDI4251 provides 10 place settings, seven programmes, a 45dB noise level and an E energy rating.
Noise figures matter when the dishwasher is close to a living area. The Beko is rated at 49dB, while the Bosch Series 2 is listed at 46dB and the CDA CDI4251 at 45dB. The Beko and Sharp have E energy ratings, while the Bosch Series 4 has a B rating alongside its stated Eco-cycle water use of 8.7 litres.
There are also models with different priorities. The Amica ADI430 is a fully integrated 45cm dishwasher with nine place settings, four programmes, a 49dB noise level and an E energy rating. Its dimensions are 815 × 448 × 550mm. Comparing the programme count, capacity, noise and energy label is more useful than choosing solely by the “slimline” label.
Not necessarily. If the kitchen already has a suitable cold-water feed, waste connection and electrical supply, fitting may not require a separate plumber. If plumbing or electrical connections need to be created, moved or altered, professional help may be required.
A dishwasher installation normally needs a water supply, a waste connection and a suitable electrical supply. The CDA installation guidance explains that the appliance can connect to a drain or to a sink outlet spigot. The Beko DIS15020 requires a cold-water supply and specifies a water-pressure range of 3–10 bar. The practical question is therefore whether the existing services are in the right position and suitable for the replacement appliance.
The standard integrated slimline format is approximately 45cm wide, with the verified integrated models in this comparison measuring between 44.6cm and 44.8cm wide, apart from the Sharp model listed at 45cm. The Smeg DI4522 is the narrowest of these integrated examples at 44.6cm, while several Bosch, Beko, CDA, Amica, Hotpoint and Montpellier models measure 44.8cm.
For a narrow kitchen opening, the relevant measurement is the appliance width rather than the marketing term “slimline”. The 45cm category is the established UK size for integrated slimline dishwashers; a 40cm or 300mm integrated model is not represented by the standard manufacturer dimensions used here.
The Bosch Series 4 SPV4EMX17G is the strongest higher-specification choice here, with a B energy rating, 8.7-litre Eco-cycle water use and a 4.7/5 Bosch review rating. The Beko DIS15020 is the better budget choice, offering 10 place settings and five programmes.
They follow a standard 45cm category, but exact dimensions vary. The fully integrated examples are approximately 81.5–82cm high, 44.6–44.8cm wide and 55–55.5cm deep.
Not always. An existing suitable water feed, waste connection and electrical supply may allow straightforward appliance fitting. Altered plumbing or electrical work may require a qualified professional.
Among the integrated models listed here, the Smeg DI4522 is 44.6cm wide. The usual UK integrated slimline format is approximately 45cm rather than 40cm or 30cm.
