Don't forget for all those who are living of equity or in some way generating income through dividends, all income protection insurance is gerared to rep,acing income. They don't recognise dividend income as income and as a result the income protection cover is not effective in this case. This is also in the case of compulsory 3 rd party insurance where their cover is based on your income.
The only insurance that I can find that gives me some cover is trauma insurance and this is then in addition to all the compulsory insurances I already pay.
This is the info I have been able to determine,to date, as you mention it is very hard to find anybody who gives you any info apart from the standard.
Cheers
