Be warned.
Ok if you want to consume it yourself, but if Trading Standards happen to find excessive amounts of sucrose in any honey they test, the supplier might well get a call.....(would you like to pay ten times as much, expecting honey and finding you have been sold sugar? We, unless we test it ourselves, don't know how much sucrose there is in our honey naturally. Trading standards can compare your sample results with other local samples - and if anomalous, alarm bells would ring at Trading Standards. Their forensic needs not to be rocket science, by any means.
Selling adulterated honey likely cost one supplier over a hundred grand a couple years back (I think it was 88 thousand for the fine + costs and then there would have been defence costs on top of that).
