Think I might have been lucky, they didn't respond in the 14 days so I requested a default judgement against them which was awarded 2 days later. In the end I didn't have to use any of the TOS stuff, missed deadlines etc.
As for residential addresses, with this being a Limited Company you cant send bailiffs there as my CCJ is against the company not the directors and they won't be able to do anything. What would be great to find is if they have a warehouse / alternative address where they hold any PC equipment / stock etc as that is part of the company and would be liable for seizure.
It doesn't really matter if they are at their address or not. As long as the order is sent to their correct address it is deemed served, even if they are not there to receive it. There are quite a few ways the court can deal with Alpha. For example you can get an order to obtain information:
Q. The debtor that I am chasing won't respond to me. Can I use an Order to obtain information from a debtor [previously known as oral examination]?
Yes, you can. This is a method by which the court can assist you in investigating the assets of your debtor. Your debtor is summoned to court to be questioned by a senior court officer or the District Judge about their assets. If your debtor is a company, a manager of the company can be summonsed to answer questions about the company's assets. If your debtor does not co-operate, the matter may be referred to a higher Judge [Circuit Judge], who can make an order for your debtor's committal to prison.
The procedure is effective in investigating your debtor's assets and the inconvenience it can cause is sometimes enough to prompt your debtor into making payment.
Then you can apply for court orders to freeze their bank accounts or put charges on their assets. This is all assuming Alpha are still around after the end of this month. Which I doubt.
