The best pressure washers for UK homes

Last updated: · By the Hearth & Lawn team

How we chose these: We haven't tested these pressure washers ourselves. Our picks are based on manufacturer specifications, UK retailer prices, independent tests (mainly BBC Gardeners' World Magazine and Expert Reviews) and patterns in owner reviews. Where sources disagree, we say so. Prices were checked on 17 October 2026. Pressure washers are often discounted, especially in spring and around Black Friday.

After a wet British winter, patios go green, paths go slippery and garden furniture goes grey. A decent pressure washer clears all of that in an afternoon, and it does the car and bikes too.

The good news is you don't need to spend much. A mid-range washer between about £110 and £200 handles most domestic jobs. The trick is matching pressure, flow and accessories to what you actually want to clean.

How to choose a pressure washer

Bar, flow and watts: what they mean

  • Pressure (bar) is how hard the water hits. More pressure shifts stubborn dirt faster.
  • Flow (litres per hour) is how much water comes out. More flow rinses loosened dirt away faster, which matters a lot on patios.
  • Motor power (watts) is a rough guide to how hard the machine can work.

BBC Gardeners' World breaks domestic washers into three rough bands:

Band Motor Pressure Good for
Light-duty 1,200–1,600W up to about 90 bar Bikes, garden tools, light furniture cleaning
Mid-range 1,600–2,000W 90–130 bar Paving, garden furniture, cars: right for most homes
Heavy-duty 2,000–2,500W 130–150 bar Large patios, driveways, caravans, heavy grime

More isn't always better. High pressure can etch soft stone, splinter decking, blast the sand out of block-paving joints and damage car paintwork. A washer with adjustable pressure (Kärcher Power Control, Nilfisk PowerControl, Bosch's twist nozzle) lets you turn it down for delicate jobs.

Accessories make the real difference

  • Patio cleaner (surface cleaner). A spinning-jet hood that cleans flat surfaces evenly without spraying muck up your walls and windows. If your main job is the patio, budget for one. Check what's available for your brand before you buy the machine.
  • Rotary or "dirt blaster" nozzle. A spinning pencil jet for stubborn grime and moss.
  • Detergent bottle. Useful for cars and algae. Use the maker's recommended products.
  • Brush. For cars, conservatory roofs and greenhouse glass.

Hose length, cable and storage

A 7–8m hose lets you leave the washer by the tap and still reach the far side of most patios. Most machines have only a 5m mains cable, so you may need an outdoor-rated extension lead, kept away from the spray. An internal hose reel (Nilfisk) or telescopic handle (Kärcher K4) makes the washer easier to store.

Corded pressure washer or cordless pressure cleaner?

Cordless "pressure cleaners" such as the Worx Hydroshot are a different kind of tool. They run on a battery and can draw water from a bucket or water butt. That's ideal if you have no outside tap, live in a flat, or want to clean muddy bikes and boots at a campsite. But they work at around 20–60 bar, a fraction of a mains washer, so they won't deep-clean a mossy patio.

Running costs and the hosepipe ban

Electricity

A typical mid-range washer is rated at 1.8–1.9kW. At the Ofgem price cap of 26.32p per kWh (average direct debit electricity, 1 October to 31 December 2026):

1.8kW × 1 hour ≈ 47p per hour of non-stop running.

The motor stops when you release the trigger, so real use costs less.

Water

At maximum flow, a K4 uses up to 420 litres an hour (0.42m³), and the Nilfisk up to 465 litres. If you're on a water meter, multiply by your water company's combined water and sewerage rate per cubic metre to see what an hour costs. Bills show it; rates vary by region.

Hosepipe bans (Temporary Use Bans)

During a Temporary Use Ban, a mains-fed pressure washer is treated like a hosepipe. Water companies' guidance says you can't use it to clean a private car, patios, paths, walls or windows. You can still use buckets, a watering can or water from a water butt, which is where a self-priming cordless cleaner can help. Some exemptions apply, for example for some people with mobility needs and for health and safety reasons. Always check your own water company's current notice.

The best pressure washers in detail

1. Kärcher K2 Power Control: best budget pressure washer

Price checked: about £95–£136 depending on retailer and bundle. Price comparison sites listed it from about £94.70; Argos sells a Car & Home bundle.

Key specs (Kärcher):

  • 1.4kW; max 110 bar; max 360 l/h
  • 5m high-pressure hose
  • About 4kg without accessories

The K2 is a very common first pressure washer, and for cars, bikes, garden furniture and the odd small patio it's fine. You get Kärcher's Power Control trigger gun, which shows the setting you've chosen, and you can add from a huge range of Kärcher accessories later.

Be realistic about its limits. At 110 bar and 360 l/h, a large, heavily stained patio will take noticeably longer than with the bigger machines below. The 5m hose is also short.

Pros

  • Cheap and light
  • Easy to store
  • Huge accessory range
  • Kärcher parts are easy to find

Cons

  • Slower on big patios and driveways
  • Short hose
  • Lower flow means slower rinsing

2. Bosch UniversalAquatak 135: best all-rounder for most homes

Price checked: from about £108 at UK retailers, against an RRP of £184 quoted by Gardeners' World. Costco UK and Lawson HIS listed it at up to about £145.

Key specs (Bosch, via retailer specification listings):

  • 1,900W; max 135 bar; 410 l/h
  • 7m hose, 5m cable
  • Three-cylinder all-metal pump
  • Self-priming from 0.5m, so it can draw from a water butt
  • 7.9kg

This is the sweet spot for most households: enough pressure for patios, a longer hose than the K2, and Bosch's 3-in-1 nozzle that you twist to change spray instead of swapping lances. Gardeners' World made it their best all-round pressure washer (4.8/5). They found it stable and fairly quiet, with no vibration, but said Bosch's accessories are pricey.

Pros

  • Strong pressure for the price
  • 7m hose
  • No fiddly nozzle swaps
  • Metal pump
  • Can draw from a water butt

Cons

  • Accessories cost more than some rivals'
  • Retailers list flow as 410 or 450 l/h. We've used 410 l/h, the figure on several UK spec listings.

3. Nilfisk Core 140-8 PowerControl: best for patios and tidy storage

Price checked: £185.99 at the Nilfisk UK shop.

Key specs (Nilfisk):

  • 1,800W; max 140 bar
  • Flow 465 l/h max (348 l/h rated)
  • 8m hose on an internal reel; 5m cable
  • Long-life metal pump; quoted cleaning speed 40m²/h
  • 8.7kg
  • 2-year warranty, extendable to 5 years if you register

Nilfisk's Core 140 gives you the most pressure here plus an 8m hose that winds away inside the machine. That's a genuine plus if you've ever wrestled a kinked hose back into a shed. The PowerControl lets you dial the pressure down for decking and cars, and it comes with gentle and rough nozzles and a detergent sprayer.

Gardeners' World rated the Core 140 4.8/5 as their best compact pressure washer. They praised how stable it is at full hose stretch. Note that they tested the earlier 6m-hose version (Core 140-6); the 140-8 adds the longer hose.

Pros

  • Highest pressure in this list
  • Long hose on an internal reel
  • Adjustable power
  • Free warranty extension if you register

Cons

  • Smaller accessory range than Kärcher
  • Assembly needs a screwdriver, according to Gardeners' World

4. Kärcher K4 Power Control Flex: best for regular patio and driveway cleaning

Price checked: from about £188 at UK retailers. The Car & Home bundles with extra accessories cost more.

Key specs (Kärcher):

  • 1.8kW, water-cooled motor
  • 20–130 bar; max 420 l/h; quoted area performance 30m²/h
  • 8m PremiumFlex hose; 5m cable
  • Plug 'n' Clean detergent system; telescopic handle; integrated water filter
  • 12.1kg without accessories

If you'll be cleaning the patio, drive and car several times a year, the K4 is a step up from the K2. You get higher flow, a longer, kink-resistant hose and a water-cooled motor that Kärcher says lasts longer. The Power Control gun has three pressure settings plus a detergent setting, and Kärcher's app suggests the right pressure for different surfaces.

Expert Reviews rated it their best all-round tested choice, but noted it's heavy.

Pros

  • Good balance of pressure and flow
  • Long flexible hose
  • Durable water-cooled motor
  • Biggest accessory ecosystem, including patio cleaners

Cons

  • Heavier than the Bosch or Nilfisk
  • Costs more than the Bosch for similar pressure

5. Worx Hydroshot WG620E: best cordless option when you have no outside tap

Price checked: about £130 at Argos, £139.99 at B&Q.

Key specs:

  • 20V 2Ah PowerShare battery
  • Self-priming from a bucket, water butt or other fresh water source; 6m hose; about 120 l/h
  • 1.7kg; five-pattern nozzle
  • Gardeners' World reports a 3–5 hour charge

Pressure note: UK retail listings and Gardeners' World give 22 bar. Worx's current European spec page gives 24 bar. Either way, it's about a fifth of a mains washer.

This is the one to buy if a mains washer is impractical: no outside tap, a flat with a balcony, or muddy bikes and dogs at the end of a walk. It runs on the same PowerShare battery as Worx's mowers and hedge trimmers. Gardeners' World rated it 4.8/5 as their best lightweight pressure cleaner.

Pros

  • Truly portable
  • Draws from a bucket or water butt, so it's usable in a hosepipe ban
  • Very light
  • Shares batteries with Worx garden tools

Cons

  • Not powerful enough for a mossy patio
  • Long recharge
  • Few accessories in the box

If you want more cordless power: Gardeners' World also rated the Ryobi RY18PWX41A-140 (41 bar, £179.99) at 4.5/5. They liked its three power levels but found it heavy and short-running at full power, at about 22 minutes.

FAQs

What bar pressure do I need for a patio? Gardeners' World suggests at least a mid-range machine (about 90–130 bar) for paved patios. Use lower pressure on block paving and wooden decking. A patio cleaner attachment gives a more even finish and stops dirty water spraying everywhere.

Will a pressure washer damage my patio? It can, if you use a pencil jet too close on soft sandstone or on joints. Start with a wide fan at a low setting, test a hidden corner, and keep the nozzle moving. On block paving, expect to re-sand the joints afterwards.

Can I pressure wash my car? Yes, with care. Use a fan nozzle or a car brush, keep a sensible distance from the paint, and avoid aiming straight at badges, seals and stone chips.

Can I use a pressure washer during a hosepipe ban? Not a mains-fed one for cars, patios, paths, walls or windows. Water companies treat it as a hosepipe. A battery cleaner drawing from a water butt or bucket is generally fine. Check your water company's notice.

Do I need an extension lead? Often, because most washers have a 5m cable. Use an outdoor-rated lead, ideally on an RCD-protected socket, and keep connections out of the spray.

Petrol or electric? For homes, electric. Petrol pressure washers are louder, heavier and need servicing, and only make sense for big commercial jobs with no power nearby.
