The first thing to note is that whatever anyone says, life assurance is still a massive profit for any adviser and thus they should be avoided at all costs.
I am presuming here that you can work out for yourself how much you want or how much you can pay and how long you want cover for. If not, then an adviser is not going to help you anyway.
For my needs, the cheapest and best is Legal and General. Now my cover on one policy is about £50 a month with L&G direct or the same via any of these comparison sites. The commission is about £2000 or more up front plus a residual commission every month for years.
If you go to www.cavendishonline.co.uk/life/ then you can pay £35 per policy and your premiums, which you pay direct to L&G, are about £35 per month for exactly the same cover. The fact is that Cavendish only get the £35 and perhaps some bonus from L&G and the commission is used to reduce your payments. You can telephone L&G to confirm this. I did.
Now in your circumstances L&G might not be the best company but do your homework and save yourself thousands and don't line the pockets of the advisers for things like this.
As an aside, you might want to review the L&G adviser centre here www.legalandgeneral.com/advisercentre/MedicalUnderwriting/Information/Underwritingconsiderati ons/Ageandsumassuredevidencelimits/page3927.html which shows at what limits and ages they start asking for all manner of extra medical evidence. All other companies have the same information on the web, though they do their best to hide it away as the advisers don't really want you and me, the stupid general public, knowing too much, such as how much commission they would like to screw out of you.
Be educated and save yourself a fortune.
