Investment Bonds Vs Executive Pensions

Hi,
A colleague of mine has told me about ways to be more tax efficient. Investment Bonds and Executive Pensions were mentioned. Since neither of us are experts. Can anyone shed some light on the pros and cons? I am an IT Contractor and a proprietary directors of my own limited company.

Thanks

Pensions certainly carry attractive tax 'breaks'. Plenty of discussion about pensions on this site, but if you don't have a clue, you should probably seek independent professional advice.

I'm not sure about 'investment bonds'-could you expand? I'm not sure that investing in bonds is tax efficient for a personal investor (see some of the threads in this search , but that may not be the case if they are bought through a company.
