Is Members Voluntary Liquidation the most tax efficient route?

This means 10% tax over and above previously paid corporation tax.

If dividend can be taken, and keep within basic rate, that is only 8.5% tax (max) over and above previously paid corporation tax.

With employer (Ltd Co) pension contributions plus dividend, the OP could get the £200k out tax efficiently within 2 tax years.
