How Much Do Bananas Cost in the UK?
Short answer: on October 19, 2026, loose bananas cost 90p a kilo at both Tesco and Sainsbury's, sold at about 16p per banana. Five-packs cost £0.78 at Tesco, Sainsbury's and Aldi, and a six-pack at Asda costs £0.94.
Bananas are the most boring price in the supermarket, and that is the point. They are a headline known-value item that supermarkets hold steady, so the guide is short: here is the price, and here is the one trap.
The prices we verified
Tesco Bananas Loose: £0.90/kg unit price, 16p per banana at the till. Sainsbury's Bananas Loose: £0.90/kg, identical. Both also sell a 5 pack for £0.78, and Sainsbury's Fairtrade 5 pack is also £0.78.
Aldi Nature's Pick Bananas 5 pack: £0.78, and a single banana at 16p. Asda 6 Bananas: £0.94, about 16p each (Asda does not state a per-kilo price for the pack).
Every route to a banana in the UK this week lands within a penny of 16p per fruit. The per-kilo loose price, 90p, is the anchor.
What is a good deal on bananas?
Our guidance: 90p/kg is the price, and banana offers are rare because the price is already competed flat. The trap is the premium formats: ripen-at-home, organic and snack-size multipacks carry higher per-kilo prices for the same fruit in a different bag.
If a banana product works out above £1.20/kg, you are paying for packaging and labelling, not for bananas.
Why banana prices move
Bananas sit in the ONS fruit class, up 2.2% in the year to August 2026, but banana pricing itself is famously sticky: supermarkets treat it as a price-perception item and absorb cost moves rather than reprice weekly.
That stability makes bananas a useful benchmark. When the loose price does move off 90p/kg, it usually signals a wider produce shift, which is one reason we track it every week.
How to pay less for bananas
Buy loose at 90p/kg and skip the formatted packs unless the pack is the same 16p per fruit, as the £0.78 five-packs are this week.
Buy twice a week in smaller quantities if waste is your problem. A thrown-away banana costs more than any price difference in this guide.
