Mortgage Protection Insurance for my UK home. I need it, but which insurance company shall I choose?

I have been offerred mortgage payment protection insurance by my mortgage lender, but it seems a bit expensive.
I think my job is OK, but I do worry as there have been a few people made redundant recently. There seems to be a lot of mortgage protection insurance online on Google UK, but does anyone have any experience of any companies or more to the point, has anyone been made redundant and had to claim with their mortgage protection insurance provider?

I used Abbey National, but they were a bit expensive. I have looked into using British Insurance who I wish I'd used.
