Does anyone know what the difference is? Going by the Fernox website they seem to have identical characteristics.

Get youself 150 gms of boric acid from the chemist (69p last time I looked). That's all Sentinel consists of, and I expect Fernox is the same
Boric acid's virtually unobtainable from pharmacies nowadays.
ISTR that it was used for preparing 'naughty' drugs, so chemists have stopped selling it.
Also used as an eyewash and general antiseptic. The big Savacentre type pharmacies do that whole range of powders in a box, or you can pick up
500gms on EBay
"Fernox, manufactured and sold by Cookson Electronics of England...utilizes carboxylic acid salts as part of the corrosion additive package"
