I'm a pimp, and part of what we do is IT, though mostly in banking. I also have done IT for a few decades.
I first of all have to ask why IT ?
It's entirely possible that your first job will pay less than your current employment.
I'd be very very wary of outfits like CompuTeach et al who suck people into their entry level programmes promising "careers in IT". The reality is that getting a first job without experience is not easy.
It's a tempting but not often wise way to spend your redundancy.
I won't use the term "rip off" for legal reasons.
Admin may be a way in to IT, though it's advantages over admin anywhere else is not guaranteed.
Ironically, I can see a good candidate for your 2nd job but not the first. There are big multi billion pound projects to to NHS IT. Frankly I think that a chemical attack by Al Qaeda will do more for the nation's health, but they need people who know healtchcare and IT.
"Need" is of course not the same as "want", but close enough for your purposes.
People on big government IT projects are hired entirely on the basis of price, not quality.
(I speak as the former director responsible for HM Treasury's largest ever capital spending project).
With all due respect, that might be to your advantage. At entry level you are cheap, which is good. I'm guessing your understanding of relational database theory is not great, but you will quickly find that you are far from the least well qualified on the project. For a start you can type in English.
I know so little about you as a person that I'm firing into the dark here, but I think the sweet spot of effort to learn vs money you can get is to master Excel.
Although almost as many people can drive Excel as drive a car, only a small % have had any formal training in it. You can imagine what roads would be like if that were applied to cars, and frankly many people's use of Excel looks remarkably like car crashes.
There is a good market for Excel people, we've dropped a few into financial outfits, and I can safely say the money was entirely to their satisfaction.
An advantage of Excel is that learning it is not an "all or nothing" game. Almost any office job can be made more productive by knowing Excel, and it's nature means that you don't have to get a "critical mass" of knowledge before you can do anything.
At the risk of overloading the car anlogy, someone who knows about the "gearbox" in Excel is a bit useful, whereas on it's own it's useless in driving a car.
That means if you give up part way through, your time & money is not wasted.
Also you can do Excel on your home PC, and is one of the few lurcrative skills that work on a standalone computer and can be self taught with a few books. (and a lot of time)
Most colleges of FE etc run Excel courses. The ECDL pleasantly surprised me for being quite good.
Also there are a lot of online resources to learn Excel, and a swarm of sites where you can ask newbie questions and (often) get an answer.
Given that I deal mostly with investment bankers, there's some jokes I could make...
One (non client) director at a household bank talks of himself in the 3rd person, is there a medical term for this ?
I can't introduce you to any of our clients, but if you want a quick commentary on your CV,
