The Financial Ombudsman have published a positive, reassuring response to the Brexit vote decision:

“While there are many things to be worked out following the vote, for now at least it’s business as usual for us. Actually, I think it’s a good prompt to reflect that it was originally UK financial businesses themselves – not the government or the EU – who, voluntarily, set up the ombudsman as a free, informal channel for resolving customers’ concerns. However “Brexit” pans out, I’m confident this spirit of fairness won’t disappear.” [1]
