Best Pressure Washers in the UK (2026)

Yes, explicitly. The Water Use (Temporary Bans) Order 2010 (SI 2010/2231) defines a hosepipe to include anything designed, adapted or used to serve the same purpose, which catches pressure washers, sprinklers and irrigation systems alike. The prohibited uses it lists include cleaning a private motor vehicle, cleaning walls or windows of domestic premises, cleaning paths or patios, and cleaning other artificial outdoor surfaces, which takes in timber decking. The maximum fine is one thousand pounds on summary conviction. The practical way round it is water that did not come from the mains: a pressure washer fed from a water butt through a suction kit is legal during a ban, and it is worth buying the kit before the ban rather than during it, because that is when they sell out.

The boiler is irrelevant - a pressure washer takes a cold mains feed and never touches it. What matters is the flow rate at your outside tap, and there is a two-minute test for it: time how long a 10-litre bucket takes to fill, then divide 600 by the number of seconds. That gives you litres per minute. Under 10 is low, 10 to 15 is acceptable, above 15 is good. Now compare that to the machine: the Kärcher K 7 Comfort Premium draws 550 l/h, which is 9.2 litres a minute, and the K 5 Classic Home 500 l/h, which is 8.3. If your tap only just manages the number, buy down rather than up - a starved machine pulses, loses pressure and feels broken. A combi that runs cold when someone opens another tap is a useful hint that you are in a low-flow property.

100 to 130 bar with a 25 to 40 degree fan, held about 200 mm off and angled across the joints rather than down into them. The 130 to 150 bar band is for rigid concrete, paths and brickwork, not for sand-jointed block paving. The risk is not the blocks, it is the kiln-dried sand between them: that sand is structural, and washing it out costs the pavement the interlock that makes it work. Re-sand afterwards once the paving is bone dry - damp sand bridges across the top of the joint instead of dropping into it - but understand that it does not fully restore the pavement, because a domestic clean is never followed by a vibrating plate. Every wash costs you a little of what holds the drive together, which is the best argument for cleaning it less often.

Not if the house is pre-1919. British brickwork of that age is almost always laid in soft lime mortar, which is a deliberately sacrificial layer meant to be repointed rather than blasted out; once it has gone the wall takes water straight into its core. Handmade bricks also carry a protective outer face formed in the kiln, and stripping it leaves a soft porous core that soaks up water and spalls at the first hard frost. High-pressure jetting has sandpapered historic buildings, and SPAB and Historic England both take the same line: clean water, a hand-held low-pressure sprayer, sponges and soft-bristle brushes, no metal brushes. If the building is listed or in a conservation area, get advice before cleaning at all. Modern cement-mortared brick is a different matter and takes 100 to 150 bar with a 40 degree fan.

There is not, and this is worth being clear about because Bosch's blue Professional and green Home & Garden ranges are genuinely battery-incompatible, and Amazon listings blur them constantly elsewhere. Every Bosch washer sold here, EasyAquatak and UniversalAquatak alike, is green Home & Garden. There is no blue Bosch Professional pressure washer on this shelf, so treat any listing or article claiming one as wrong. Beyond that: Kärcher is the reference brand in the UK, holds ten-plus SKUs in the category and has the accessory range every shed and Screwfix stocks, which matters more than people expect because a surface cleaner or a longer hose bought later has to fit. Bosch green is the value play and carries the deepest owner records here. Nilfisk builds well - a long-life metal pump on the Core 140 - but sells a fraction of Kärcher's volume on Amazon UK, and its Click&Clean accessory fitting does not take Kärcher parts.

Because on Amazon UK the cordless end of this category is almost entirely unbranded. Fifteen of the top thirty sellers are interchangeable "21V cordless" handhelds from names that change month to month, most with a couple of hundred ratings and no manufacturer to go back to, and ranking the category by sales would hand the whole list to them. They are also a different tool rather than a cheaper version of the same one: a battery handheld siphons from a bucket or a butt, runs for a few minutes a charge and produces a small fraction of the pressure of anything ranked here. For rinsing a mountain bike, a muddy dog, a wetsuit or a paddleboard where there is no tap, that is genuinely useful. For a driveway, a render wall or a year of patio growth, it is not the tool. Credible cordless machines do exist - Worx and Kärcher both sell one - but they sit below the mains machines here on every dimension this ranking scores.

This category is seasonal in a way power tools are not, and the cheapest moment is the one furthest from when you want it. Black Friday falls on 27 November 2026 and is the deepest discounting of the year, followed by Boxing Day and the January sales - all of them months before you will use the machine, which is exactly why the stock moves then. The next window is the run-up to Easter on 28 March 2027, when the garden season opens and every shed in the country puts washers on an end cap, then the May bank holidays on 3 and 31 May 2027 and Father's Day on 20 June 2027. Buying in the middle of a hot dry summer is the worst timing of all, partly on price and partly because that is when a hosepipe ban is most likely to stop you using it.
