queststarz - as far as LA fostering goes, avoid Birmingham. They are in a mess, incredibly short staffed and under resourced in every way. Not the fault of the sws it's just how it is. I think Solihull is ok and I worked for Worcestershire as a sw and tm mgr of a fostering & adoption team for 25 years and so I am going to be biased towards them. Don't know anything about Warwickshire. Incidentally I would avoid Wolverhampton for the same reasons as B'Ham.
As "fostering" says IFAs pay more, but of course it is the LA that pays because the IFAs charge very high fees and yes they pay their carers more, but they also cream off huge profits for themselves, making cash strapped LAs even worse off. LAs have to use IFAs because of the shortage of in house foster placements and have no option but to pay these enormous fees. IFA carers say that the children get better support, which of course they do, but again it is the LA that is paying for all this support. I know IFA managers who drive Porches and one who has a tring of race horses. Of course it is encouraged by all governments as they love privatisation.
The other thing is that with an IFA you could have a child placed from anywhere in the country, whereas with the LA you know it will be a child from within that authority, or very occasionally a neighbouring authority. Imagine a child who lives in Cornwall being placed in Dundee, and having to travel miles and miles for contact etc.
The last para of "fostering's" post is true. I am now retired but I hear from colleagues that more and more placemens are IFA plcts as there are not enough in house plcts. It is a wonder to me that there are still loyal people with integrity who foster for the LA rather than choose to line the pockets of these entrepeneurs, and don't be fooled by the "not for profit" ones - they are all in it for profit.
Worcestershire used to be excellent, but I think things have changed for many LAs in the past few years with greater staff shortages, and all of the facing massive cuts this year.
Do remember that you won't be guaranteed placements 52 weeks of the year, though it does depend on what age range you are thinking of - but even then there is no guarantee of being kept in placements, though the demand far outstrips supply.
Good luck whichever way you go.
