Possible "safe" investment

This claims to pay 7.5%/year if left for 5 years, based on A rated
insurance contracts and short term paper, cash deposits, etc.
(no stock market dependency)

It's the Secure Income Plan 3 from KeyData, see:
http://www.keydata.co.uk/sip3/
The only risk is supposed to be defaults in the contracts.
It sounds ideal for my ISAs and SIP

Here's my questions:
1. Does anybody know anything about KeyData. Are they in good standing
with a good track record. I felt a bit better after seeing my local
building society offering one of their products.
2. Are there any similar schemes/offers around from other providers as
I don't want to put too much money in one place

I'm looking at doing it via Cavendish who will kick back most of the
commision. http://www.cavendishonline.co.uk/COL/Home.htm

TIA for any wise words.
