It may be easy to do it yourself, pug, but it depends how much time your son has got..... we claimed PPI through a company (not the one you mentioned) and they did all the work for us, all we had to do was fill in a form for each claim, they did all the submitting and chasing up for us. We didn't have to do anything more. It worked too - apart from a couple which have gone to the Ombudsman as the companies are digging in their heels. As busy working people it was worth us paying the 20% to the claims company.
