Out of interest... why are you not considering retirement?... 30 years in management would surely have built up a pension pot.
I was in a similar position, when I was made redundant at 53. I had enough to retire on (just) but missed going to work/Office banter etc.
It took me a couple of years to get back in to the saddle. I accepted a lowly paid Scanning job at the council but am now back in System Admin.
You don't need to volunteer too much information on your CV. If you mention you have O-Levels, a prospective employer will know that you are at least in your mid-40s.
Networking helps. If you know people at a company already, it definitely helps.
Good luck to everyone looking.
