Buying Guide
New, Refurbished or Second‑hand
At under £100 you’re generally looking at used, refurbished or very occasional clearance/portable models. Decide whether you’re happy buying second‑hand (cheaper but higher risk) or want a refurbished unit with a short warranty from a reputable seller.
Type and Size
Full‑size dishwashers rarely appear under £100 unless second‑hand, so consider slimline (45cm) or countertop/portable machines for small kitchens or student flats. Check physical dimensions, door swing and whether the machine will fit on or under your worktop.
Condition and Key Components
For used units, inspect the pump, heating element, spray arms, door seals and filter for wear, leaks or blockages; ask for photos or a working demonstration. Confirm all cycles function, that it heats up properly and there are no persistent odours or rust.
Running Costs and Water Use
Even cheap machines can be costly to run if they’re old or inefficient - check typical water usage per cycle and whether the heater still works (cold‑wash cycles won’t sanitise). Factor in likely electricity and detergent costs over the lifetime when comparing options.
Installation and Compatibility
Think about whether you need a plug‑in portable with a tap adaptor or a fixed hardwired install for under‑sink plumbing. Ensure hoses and connectors are compatible with UK taps and that you can disconnect and move the appliance if you rent.
Frequently Asked Questions
What is the best dishwasher under £100 in 2026?
In 2026 you’re unlikely to find a brand‑new full‑size dishwasher under £100; the best choices at that price are well‑inspected second‑hand or refurbished machines from reliable brands such as Bosch, Beko or Hotpoint, or compact countertop/portable models. Prioritise sellers that offer a short warranty and proof the heater, pump and seals are in good condition.
Is a dishwasher worth buying in the UK if I only have £100 to spend?
It can be, if you’re prepared to buy used or refurbished - you’ll get convenience and water savings compared with repeated hand‑washing. However, factor in potential repair costs, transport and installation; sometimes saving a little longer for a newer, energy‑efficient model is more economical long term.
Which dishwasher offers the best value for money under £100?
Value under £100 usually means a reliable used unit from a mainstream brand (Beko, Hotpoint, Bosch) bought from a trusted source like eBay, Gumtree with good photos or a refurbished appliance seller offering a parts warranty. Look for low noise, working heater and no leaks rather than cosmetic condition.
Bosch vs Beko – which should I buy on a tight budget?
Bosch typically has stronger build quality and longer‑term reliability, while Beko is often cheaper to repair and easier to find spare parts. For under £100 pick whichever unit has a verifiable working heater and pump and comes from a seller with a returns or short warranty policy.
Can I buy a new dishwasher for under £100 in the UK?
New full‑size dishwashers rarely retail for under £100 in the UK; you might find portable countertop models or very occasional clearance items close to that price. For a reliable new built‑in or slimline dishwasher you should expect to pay several hundred pounds.
Where are the best places to find reliable used dishwashers under £100?
Check local marketplaces like Gumtree, Facebook Marketplace, eBay and specialist refurbished appliance retailers; also look at local independent salvage yards and auction sites. Always ask for clear photos, a demonstration of a working cycle and, if possible, a short written warranty.
Are portable or countertop dishwashers any good?
Portable and countertop dishwashers are excellent for small households, students or rented flats as they’re plug‑in and use less water per cycle. They tend to have smaller capacity and can be slower, but are convenient where plumbing changes aren’t possible.
How much does a dishwasher cost to run per cycle in the UK?
Costs vary with age and efficiency; a modern efficient dishwasher might use 6–12 litres and 0.6–1.0 kWh per cycle, costing roughly £0.12–£0.50 per wash at typical UK energy prices (variable). Older or poorly maintained machines can be significantly more expensive due to higher water and energy use.
What is the best dishwasher under £100 for a student flat in 2026?
A compact countertop or slimline second‑hand unit with a working heater, low water use (around 6–10 litres per cycle) and a plug‑in connection is best; prioritise models from Beko or Hotpoint that include a functioning timer and leak‑free seals. Buy from a seller offering a short warranty or demonstration to reduce risk.
Is buying a refurbished dishwasher under £100 worth it in 2026?
Yes, if the refurbishment includes testing and replacement of pump, heater and seals - that ensures reliable cleaning and lowers future repair costs. Avoid units sold ‘as is’ without a working demonstration unless you can handle repairs yourself.
Bosch used dishwasher vs Beko used dishwasher – which should I buy under £100?
Choose Bosch if you prioritise longer‑term durability and quieter operation, and Beko if you want lower initial cost and simpler, cheaper spare parts; under £100 the deciding factor should be the actual condition - working heating element, no leaks and a functioning pump trump brand.
Which dishwasher is best value for money in the UK if my budget is under £100?
A refurbished slimline or countertop unit from a reputable refurbisher that includes a 3–12 month warranty and has verified low water/electric consumption offers the best value. Look for tested heater and pump, soundness of door seals and clear proof of a working cycle before buying.
