Be careful with money transfer companies, they are not banks and have no government backed compensation scheme.
They will all boast that they are regulated; in the UK it?s FCA. They are regulated because it is compulsory and not by choice. Regulated means they are given a rule book and a sample audit is done every few years. If the regulator receives several serious complaints about a company it may carry out a spot audit within 6 months of receiving the complaints. The FCA has had several different names in the past and usually changes it?s name after a financial scandal where it failed to regulate. Money transfer companies will tell you some great stories like your money is segregated and safe, but not so forthcoming that if they go bankrupt you will join the queue with all the other unsecured creditors and maybe end up with zero.
