The True Cost: We Found the Cheapest Refillable Multi-Surface Cleaner in the UK.

Not always! As our data shows, bulk liquid refills (like the 5L Ecover) often beat the cost of concentrates when calculated per millilitre. Concentrate drops are better for reducing weight and transport emissions, but the large pouches usually win on pure cost efficiency. See our full cost breakdown.

‘Closed-loop’ means the packaging is returned to the manufacturer (often via a pre-paid service or collection point) to be professionally cleaned and reused, rather than simply recycled. Brands like Splosh operate on a closed-loop system for their refill pouches, minimizing waste completely.

The concentration of the product varies wildly. A tiny £1.75 concentrate drop that makes 750mL of cleaner must be compared against a £7.20 ready-to-use 2L pouch. Cost/mL normalizes the comparison, giving you the true unit price regardless of how condensed the product is.
