Urgent help! Dairy allergy formula in UK

I have been using Aptamil Allepro syneo 2 for my baby who is intolerant to dairy. I'm traveling and I suspect that I'll run out of the formula I have got before we head back home to Sydney. I have family coming over from the UK in a couple of days. Can any one here suggest which is the equivalent formula that I can ask them to get for me please? Is Aptamil pepti the same? There are no milk allergy formulas available where I am.
