Hi Luke
The first issue is the most effective way to take cash out of a company.
You say you are a director? I assume you are the sole owner?
At some stage, you have to take the cash out and when you do, you have to pay tax on it. ( You might be able to do a plan to extract it tax efficiently on retirement or on sale of the company, but unless this is in the immediate future, then you should take the cash out now - either as salary or as pension.)
While pension contributions are the best and most tax-efficient, long-term savings option, you must remember that you will pay tax when you draw down your pension.
The company can fund your pension without much in the way of limits, so you are not losing out by deferring pension contributions to later.
