Persil increases pack sizes but not pricesWhich laundry detergent is best value for money?

05 May 2016


Persil's new bigger packs use 70% less plastic than the previous box, according to manufacturer Unilever

Persil washing capsules now come in bigger packs, but shoppers shouldn't have to pay any more as manufacturer Unilever says RRPs will remain the same.

The new packs for Persil bio capsules, Persil non-bio capsules and Persil colour capsules contain two or three more capsules than they did previously, bringing them up to 12, 22 and 38 washes per pack. 

By our calculations, this would make the cost per wash 38p - but that's some way off the cheapest we found in our last round of laundry detergent tests.

Save money on washing powder and laundry detergent

Persil says that the RRP of its new 22-wash pack is £8.32. But our research reveals that you shouldn’t need to pay more than £6 for the pack at some supermarkets.

Our analysis of supermarkets’ prices from the last two months found that Sainsbury’s sold the 22 wash pack for £6 for all 60 days. Tesco also sold it for £6 for one third of the time (or 22 days). So it’s worth shopping at these stores for the best chances of finding a low price, based on the past two months’ data.

Asda and Morrisons’ prices were consistent: £6.85 and £6.83 respectively every day they sold it – still less than the RRP.

But the cheapest price we saw was £3.50 at Waitrose (but only for 18 days). The highest price we found was £7 at Tesco and Waitrose.

To calculate the above prices, we tracked the price of Persil bio capsules in a 22-wash pack from February to April 2016, across five major supermarkets using supermarket price comparison website The prices include discounts but not multibuys.

Is Persil detergent any good?

Over the last year, we’ve put 14 washing capsules and 16 washing powders through our tough independent tests to uncover which deliver the best cleaning power and value. This includes Persil bio and Persil non-bio capsules.

We test how well each laundry detergent removes everyday stains, including tomato sauce, mud and red wine, as well as if they’ll keep your whites pristine and colours bright. The very best will blitz even the toughest stains from your clothes, while preserving their colours. These excellent detergents are named Best Buys.

But our tests also reveal the products which will leave your laundry stained and turning grey after repeated washing.

Alongside our test results, we work out the cost per wash of every product – so you can find a brilliant stain-buster that’s also great value.
