Additional Rate Taxpayer & Savings/Investing Strategies

moneysavergirl2

My husband is currently an additional rate taxpayer. We want to make the most of this income while it lasts & make the most of any tax savings.
We have:
Maxed ISA, maxed Premium Bonds, have a Family Windfall Bond (live in NI so other similar products available in the mainland are not available to us), increased pension contributions.
Next on the list is a fund account for share investing.

Is there anything I have missed, or anything else we can do to tax efficiently invest or save tax?
We have a reasonable mortgage but the rate is really low, so happy to leave it ticking over at the minute.

It can be a very complicated area for additional rate taxpayers but making sure he has made the maximum possible pension contributions would be a good start as it is hard to beat the tax benefit there.
