Pressure Washer Buying Guide UK
Electric, petrol or diesel? Find the best pressure washer for your job and understand what to look for before buying.
How to choose the right pressure washer
The best pressure washers are matched to the job, not simply the highest advertised pressure. Compare water flow (LPM), working pressure (bar), power supply, pump quality, duty cycle, portability and service support.
Electric, petrol and diesel pressure washers compared
Electric pressure washers
Best for cars, patios, garages, workshops and fixed valeting bays. Convenient, generally quieter and no engine exhaust at the point of use. Larger commercial models may need special electrical supply.
Petrol pressure washers
Best for professional driveway cleaning, mobile operators, farms and building sites without mains power. Portable and powerful, but require fuel, servicing and safe outdoor ventilation.
Diesel pressure washers
Consider for demanding industrial or agricultural applications, especially where diesel fuel is readily available. Compare weight, purchase cost, duty rating and servicing needs.
Which pressure washer is best for each job?
| Job | Suggested type | Why |
|---|---|---|
| Cars and motorcycles | Electric | Convenient controlled cleaning; select a safe nozzle and distance. |
| Domestic patios and driveways | Electric or petrol | Electric for occasional use; petrol for larger jobs and mobility. |
| Professional driveway cleaning | Commercial petrol or high-flow electric | Water flow and duty rating support productivity. |
| Valeting bays | Electric or wall-mounted | Fixed installation and convenient daily access. |
| Farms and construction sites | Petrol or diesel | Independent of mains electricity where appropriate. |
| Greasy workshops and fleets | Hot-water pressure washer | Heat helps break down oil and grease. |
Bar and LPM explained
Bar measures pressure; LPM measures water flow. High pressure helps loosen dirt, while flow helps rinse it away and cover large areas. A 200 bar, 21 LPM machine moves more water than a 185 bar, 12 LPM model, but requires adequate water supply. Compare continuous working ratings rather than maximum marketing claims.
Honda engines on petrol pressure washers
Honda GX engines are popular on professional petrol pressure washers thanks to their established reputation and parts support. The GX200 is commonly used on compact professional machines, while the larger GX390 can power higher-output commercial configurations. Always compare the complete machine, including pump, pressure, flow, frame and accessories, not the engine alone.
Hot-water and wall-mounted pressure washers
Hot-water pressure washers are useful for grease and oil. Wall-mounted pressure washers can be ideal for detailing studios, wash bays and garages where floor space and tidy hose storage matter.
Pressure washer buying checklist
- What surfaces and dirt will you clean?
- How many hours will the machine run?
- Is electricity available?
- Is water flow sufficient for the machine?
- What working pressure and LPM do you need?
- What hose length, reel and nozzles are included?
- What warranty, parts and service support are available?
Safety: Never run petrol or diesel engine-driven pressure washers indoors or in enclosed or poorly ventilated areas because of carbon monoxide risk.
Frequently asked questions
Is petrol better than electric?
Not always. Petrol suits remote and mobile work; electric can be better for fixed locations and convenient everyday use.
What pressure washer is best for driveways?
For occasional domestic use, a suitable electric model may be enough. For professional work, compare commercial machines with adequate flow and a compatible surface cleaner.
Does more bar mean better cleaning?
No. Flow, nozzle choice, pump quality and the surface being cleaned matter too.
Are Honda pressure washers a good choice?
Honda-powered machines are a popular option, but evaluate the full specification and intended use.
