Product type overview
washing powder sits within Laundry Detergent & Softener, part of Household, Pets & Other. On this page you compare 97 products from 9 UK supermarkets: Aldi, ASDA, Co-op, Iceland, Morrisons, Ocado, Sainsbury's, Tesco and Waitrose. The lowest unit price for washing powder is £1.85/kg at ASDA. In total, 4 variants of washing powder are compared (different pack sizes and compositions). All prices are normalised to the same unit (per kilogram, per litre or per piece) so that packs of different sizes can be compared fairly — a larger pack is not automatically the best value. The ranking below shows, per variant, which supermarket currently has the sharpest price, including own-label products alongside national brands. Prices refresh daily from the retailers' own public price lists, so you never see stale offers when planning your weekly shop. Allsupers uses no affiliate links or paid placement; the ranking is purely price-based and updated from public data.
