Erm not really. You cannot just 'ditch your business' - as a director, you have many legal obligations.
If the company has traded, then there is a lengthy and costly process to winding down a company. You need to appoint a liquidator and the process can take the best part of 18 months. I've just closed a limited company and that cost me around £1,500 on top of the accountancy/administration charges of £1,000.
