What you're actually getting
Four 730ml bottles of Fairy Max Power Antibacterial for just over a tenner. That works out at roughly £2.53 a bottle, which for Fairy specifically is a proper solid price. This isn't some supermarket own-brand you're gambling on. Fairy is the one everyone's mum used and it genuinely does last longer than cheaper alternatives. The Max Power version is a bit thicker, cuts through grease noticeably faster on things like bacon pans or anything that's been sitting too long.
The antibacterial claim is worth something if you cook raw meat regularly or have small kids touching everything. Not a miracle, but not nothing either.
Who this is actually for
Honestly, this is for anyone who goes through washing up liquid at pace. Big household, someone who cooks every day, or just the sort of person who bulk-buys sensibly to avoid paying full price at Tesco every three weeks.
If you live alone and wash up twice a week, four bottles might feel like overkill. Fairy keeps indefinitely though, so storage is the only real barrier.
One small reservation: the 1,308 heat score on HotUKDeals suggests stock is moving fast. These community-validated deals tend to disappear quietly with no warning. So if you're on the fence, don't sit on it too long.
The honest take
Not glamorous, obviously. But this is the kind of deal that quietly saves you a few quid over the year without requiring any effort. Fairy Max Power is a step up from the standard stuff, the price per bottle is fair, and four bottles means you won't be panic-buying at full price for a good while. Spot on for what it is.
