Redundancy and notice

Hi, hoping you can help.

I was made redundant as of the 14th Dec, and before they announced that they told us they may or may not be able to salvage it on the 4th Dec.

I have since made a claim for money owed through the redundancy payment service. But what I want to know is how much am I likely to receive for lack of notice? I worked there for less than two years and I know statutory is 1 week but my contract said a month so when I get my form through will I get paid a weeks worth or a months worth?

And is that worth my actual wage I was on at the time x the actual hours I would have worked or it is the minimum wage?

The other thing that I am interested in people’s opinions is a protective award for not consulting collectively. The administrators sent two letter one on the 4th Dec advising they need to see if they can get a buyer etc and then a second letter on the 14th Dec saying everyone is redundant. The company has made more than 20 redundancies so gov website says they have to consult for 30 days. What’s the chances of me putting forward my argument that I don’t think they have followed the rules? Or should I leave it since they have gone into administration? And if perhaps I do have cause who I complain direct to the administrators first? I’m going to call Acas too and I’ve asked citizens advice but just curious if anybody else has had similar experience and what they did.

Thanks in advance.
