Taking money out of ISA to put in Pension?

If you were to make payments from your limited company then it can be treated as a company expense so no corporation tax or income tax is due. You can do that instead of drawing PAYE or dividends from the company and you can use your ISA to live on. You may also have the option to carry-forward any used allowances from the last 3 years so that might be worth investigating as well.

Putting money into a pension would get money out of your estate for inheritance tax purposes, so if IHT is a factor you need to consider, then it's a pro for this.
Age and accessibility to the money is another. If you need to access some of this money in the near immediate future, then maxing your pension contributions might not be a good idea.
If you are approaching the Lifetime Allowance (currently £1.03m) then putting money into the pension might not be a good idea either.
Are you married? It might be a better idea to contribute to their pension instead if some of the above factors come into play.

It's not an easy topic with a definitive answer. A lot of factors come into play in terms of your circumstances, age, ambitions, requirements etc...

If you decide to use your ISA money & assuming your S&S isa isn't flexible, may I suggest you move it to a flexible cash isa first (for example Ford Money) which allows you to w/d the money without losing the allowance, and thence into your pension.

This allows you to replace the money taken from the ISA upto the end of the current tax year (and to add this years allowance) should you have the available funds.
