Pressure washers

Pressure washers usage and safety

Pressure washers make it quick and easy to clean your driveway, decking, patio, fencing or car. But they can pose a safety risk if not used and stored properly.

When choosing a pressure washer, how much power it generates and its water pressure tend to be the main priorities. A basic, lower-powered machine is fine for small garden tasks such as cleaning equipment or washing bikes.

Mid-range washers (usually at least 1600 watts of power and water pressure above 90 bar) can cope with cleaning paving and garden furniture as well as most cars. Higher powered ones are more for bigger tasks such as cleaning caravans or large outdoor spaces.

Key points

  • All pressure washers must be fitted with a UK 3-pin plug and fuse. 

  • Whichever type you choose, avoid buying second-hand washers. 

  • Keep the area to be cleaned clear of large debris. 

  • If using an outdoor socket, ensure it is splashproof or waterproof. 

Buying a pressure washer

  • Whichever you choose, buy from a reputable retailer rather than a third-party seller online as the appliance may not have passed all the necessary safety checks.
  • Essential safety features to look for in pressure washers include trigger locks to prevent accidental discharge, automatic shut-off if a leak is detected or the pressure exceeds a certain level, and thermal relief valves to prevent overheating and potential damage.
  • More expensive models may also have a detergent tank, more durable pumps to handle higher pressures, and noise-cancelling features.   
  • Register your pressure washer so you can be contacted easily if there is a safety recall. It’s also much easier to return a faulty product or order a repair if it’s registered.

Using a pressure washer safely

  • Use the pressure washer according to manufacturer’s instructions and follow its safety procedures. Don’t use a pressure washer if it’s raining or windy
  • Make sure the area to be cleaned is clear of any hazards and large debris before starting. Consider wearing safety glasses in case of any spray back.
  • If spraying anywhere near electrical products or sockets, ensure they’re properly covered and never spray directly towards them.
  • Regularly inspect the full length of any power cables for any damage and wear. 
  • Always be in a stable position when using the washer. Avoid using ladders or anything which could cause you to lose your balance.
  • If you notice a burning smell or any unusual noises, unplug the pressure washer immediately and contact the retailer and/or manufacturer.
  • Unplug the pressure washer at the socket when not in use. Store it in a cool, dry place such as a shed or garage.
  • Sockets which supply equipment outdoors should be protected by an RCD (residual current device) to protect you from electric shocks should there be a fault with the product. 

ALWAYS

  • Do plenty of research first before buying.

  • Buy a known and trusted brand from a reputable retailer.

  • Register your pressure washer with the manufacturer.

  • Store the washer in a cool, dry place.

AVOID

  • Buying second-hand pressure washers or from third-party sellers online. 
  • Using a pressure washer if it’s raining or windy. 
  • Spraying water directly towards other electrical products or sockets. 
  • Using the washer from a ladder.
  • Using the pressure washer if there are signs of damage. 

Stay safe with electrical products

Check plugs and sockets

Don't ignore burn marks, ‘arcing’ (buzzing or crackling) sounds, fuses blowing, circuit-breakers tripping, or if it feels hot to touch.

Unplug and contact the retailer, manufacturer, or a qualified repair technician. 

Protect with an RCD

An RCD (residual current device) in your consumer unit (fusebox) protects you from electric shocks if a product is faulty.

If you don’t have RCD protection, use an RCD plug on the socket where the product is plugged in.

Fit smoke and heat alarms

Ensure there is at least one smoke or heat alarm per floor in your property. Fit enough alarms to cover all areas where a fire could start.

Test alarms at least once a month. Replace them every ten years or when the replace by date is reached.

Selected FAQs

If you’re unsure about an appliance or product, you’re not alone. These FAQs bring together expert advice and answers to the questions people ask us most, so you can feel more confident at home.

It is recommended that periodic inspection and testing is carried out at the following times:

  • for tenanted properties, every 5 years or at each change of occupancy, whichever is sooner
  • at least every 10 years for an owner-occupied home
  • at least every 5 years for a business

The Landlords and Tenant Act 1985 requires landlords of properties with short leases to keep the electrical wiring in repair and in proper working order. We recommend landlords arrange for periodic inspection and testing to be carried out by a registered electrician at the relevant intervals shown above.

Periodic inspection and testing of the electrics should be carried out more frequently on the places and premises listed here:

  • 3 years for a caravan
  • 1 year for a swimming pool

Periodic inspection and testing should be carried out only by electrically competent persons, such as registered electricians.

First, you need to find out whether the electrician you used is actually registered. To do this, contact the operator of the scheme they have claimed to be part of, and they will tell you whether this is the case. If they are registered, the scheme operator can guide you through their complaints procedure.

If you find out the electrician misled you and is not registered, you should report this to your local Trading Standards Department as they are breaking the law. We would also recommend that you get an Electrical Installation Condition Report (EICR) carried out on your home; this will assess any work that has been undertaken and will act as sufficient documentation to certify that work. This needs to be carried out by a registered electrician and unfortunately will be an added cost for you.

Additional info

A more powerful pressure washer used at higher pressure settings or for longer durations uses more energy than smaller, less powerful units used intermittently or at lower pressure settings.

Cordless pressure washers are also available and run on a battery, although generally they have less power overall.

Has your electrical product been recalled?

Electrical products are recalled more regularly than you might think, but the response rate to a recall is often worryingly low. This means there are potentially millions of recalled electrical items still in UK homes.
