When a business goes bust, a Receiver (or an Administrator) is brought in. They decide what to do - to split the business up ands sell the assets or try and sell the business as a going concern. If it is sold as a going concern and you are transferred with it, TUPE applies - and you continue working for the new company under the same T&cs of your contract (initially at least). In which case you aren't being made redundant.
If the company is broken up you will be declared redundant by the Receiver. You will receive a redundancy payment if you are entitled, either from the company if it has any money left, or from the Government fund if the company has no money.
You will either get redundancy or your job - not both and not neither.
You will have to ask the Receiver which of these is going to happen - I'm sure he is tell you soon enough. Good luck.
