Buying Guide
Pressure and flow (power)
Look at both the maximum pressure (bar or PSI) and the flow rate (litres per hour or minute). For general DIY jobs under £300, aim for roughly 100–140 bar (or the equiv. PSI) and a flow of around 350–450 l/h; higher flow cleans faster on large, flat surfaces.
Motor type, build quality and durability
A robust motor and metal pump components will last longer than cheaper plastic assemblies, especially if you use the washer often. Check wattage and reviews for reliability — well-known brands tend to offer better long‑term support and spare parts in the UK.
Hose, cable length and portability
Longer hoses (5–8 m) and a long mains cable make cleaning bigger areas without moving the machine easier, while compact, wheeled designs are simpler to store. Consider weight and whether you need to carry it upstairs or store it in a shed.
Accessories and detergent handling
Useful extras include adjustable nozzles, turbo/rotary jets, a foam lance for cars and an onboard detergent tank or easily attachable bottle. Ensure the washer supports low‑pressure detergent mode and comes with the fittings you need, otherwise extra accessories can quickly push the total cost above £300.
Warranty, aftercare and where to buy
Check the warranty length and whether the retailer offers returns or local repair — retailers such as B&Q, Screwfix, Halfords and Amazon UK are common choices. A slightly higher initial spend on a model with a 2–3 year warranty can save money if you use the machine frequently.
Frequently Asked Questions
What is the best electric pressure washer under £300 in 2026?
There isn’t a single best model for everyone in 2026. The best choice depends on use: for cars and patios look for ~110–130 bar, ~350–450 l/h flow, a foam lance and a 5–8 m hose; reputable brands such as Kärcher, Bosch, Nilfisk or Ryobi often have the most consistently reliable options in this price bracket.
Is an electric pressure washer worth buying in the UK?
Yes, if you regularly clean cars, decking, patios, garden furniture or driveways an electric pressure washer saves time and usually uses less water than a hose. For occasional spot cleaning a hose with a jet attachment may be sufficient, but washers give better results on thicker grime.
Which electric pressure washer offers the best value for money?
Value usually comes from a balance of usable pressure/flow, solid build (metal pump parts), useful accessories (foam lance, adjustable nozzle) and a decent warranty. Mid‑range machines from established brands often represent the best value because they include spare parts and retail support in the UK.
Kärcher vs Bosch — which should I buy?
Both brands are strong: Kärcher is known for extensive accessory ecosystems and long service history, while Bosch often focuses on user‑friendly designs and quieter motors. Choose Kärcher for a wide choice of attachments and proven durability, Bosch for compact, easy‑to‑store models — compare specific model pressure, flow and included accessories.
Can I use an electric pressure washer on my car?
Yes — but use a lower pressure setting or a gentle nozzle and a foam lance to avoid paint damage. Keep the nozzle at a safe distance (usually 30 cm+) and avoid directing a high‑pressure jet at rubber seals, tyres or delicate trim.
Do I need a special extension cable or a particular socket?
Use a heavy‑duty, outdoor‑rated extension lead if needed and keep cable length as short as practical to avoid voltage drop. Most domestic electric pressure washers run from a standard 13 A socket; check the machine’s power rating and any guidance on the manufacturer’s plate.
Are petrol pressure washers better than electric ones?
Petrol models offer higher pressure and flow suitable for very large or heavily soiled surfaces, but they’re noisier, heavier, require fuel and more maintenance, and are usually above £300. For typical domestic tasks in the UK, electric machines are quieter, easier to store and more convenient.
Where can I buy the best deals in the UK?
Check major retailers like B&Q, Screwfix, Halfords, Amazon UK and Argos, plus manufacturer outlets during seasonal sales. Compare total cost with essential extras (foam lance, turbo nozzle, hose extensions) so the final price stays within your £300 budget.
