Problem getting a mortgage?

There I was siting at home indulging in some light blogging when my home telephone rings. It is a recorded message from Britain's largest mortgage advisor offering to help me get a mortgage if I have ever had problems getting a mortgage in the past. Apparently this company specialises in helping people with a poor credit history get a mortgage. Bearing in mind the sub-prime problems in the USA and the coming financial storm in the UK, does anybody think this type of marketing is wise?
