Common questions
Where does the product data come from?+
We use Open Food Facts, a free and open database of food products. It is updated by contributors around the world, so coverage is good but not perfect. If a product is missing, you can add it to Open Food Facts directly.
Can I search without a barcode?+
Yes. You can search by product name, brand, ingredient, category or manufacturer. The barcode scanner is just the fastest way when you have the packet in front of you.
What does 'needs verification' mean?+
It means the ingredient might be halal or haram depending on its source. E471, gelatine, rennet and 'natural flavouring' are common examples. We flag them so you know to ask the manufacturer or look for a trusted certification logo.
Is HalalScan UK free?+
Yes. The scanner, search, E-number database and ingredient analysis are all free. We may add optional paid features for businesses in the future, but the core shopper tools will stay free.
