Making a claim for PIP does not mean that you
have to claim UC.
However from what you say there then I would expect you to get
much more money with UC than you are currently getting with IR ESA.
So in your circumstances it's probably time to consider whether to move yourself over, (Voluntary Migration), rather than waiting until the DWP tell you that you have to, (Mandatory/Managed Migration).
As your local CAB seem to be being useless I've done a comparision for you:
From what you have said I make it that you currently get IR ESA WRAG as a couple, and because of your wifes CA you should have a Carer Premium included with that.
Whether or not you are being paid for WRAG depends on if you claimed ESA before 3rd April 2017.
For the moment I'll assume that you did and are being paid for the WRAG and so with WRAG and Carer Element you are entitled to IR ESA of £190.50 a week.
Of course your wife's CA of £69.70 gets deducted from the ESA as income, so that should currently give you £120.80 a week IR ESA being paid.
Please let me know if that isn't what you are getting.
Your wife gets CA for looking after your son, and possibly Child Benefit.
Your son may have Child DLA. (It would be helpful to know how old he is, and if he does get DLA what rate of daily living. Plus do you have other children).
You may have Housing Benefit?
In a migration to UC the only things that would be migrated are the IR ESA and the Housing Benefit, the rest would continue as they are.
Any Housing Benefit will change to a UC Housing Element and pay the same amount.
So it's really only the IR ESA that we need to look at, because all the rest would stay as they are.
The calculated monthly equivalent of your IR ESA is £524.91 a month (£120.80 x 52.143/12).
With UC you should get: (I've used the lowest amounts, but shown possible higher one in brackets).
£ 525.72 Standard Allowance, couple over 25.
£ 132.89 LCW Element. (Only paid if you were already getting paid for ESA WRAG).
£ 244.58 Child amount. (First child born after 6 April 2017 - it will be £290.00 if he's older). (A second child is another £244.58).
£ 132.89 Disabled Child addition, lower rate care of DLA. (It will be £414.88 if he has the higher rate care of DLA).
£ 168.81 Carer Element, because of your wifes CA.
£ ???.?? Housing Element, the same amount as any HB you currently get.
£1251.81 UC entitlement, (plus any Housing Element).
£-302.03 Deduction because your wife's CA counts as 'unearned income'. (Just like it does for IR ESA).
£ 949.78 UC payable each month, (plus any Housing Element)
Obviously I have had to make a few assumptions there, in particular that your son has DLA, but
even using the lowest UC rates I calculate that you could expect to get UC that is almost double what you are currently getting paid as IR ESA. (It's an 81% increase).
Carers Allowance, Child Benefit, and DLA all stay outside of UC and would continue to be paid as they are now.
If you would like to clarify a few details, ie.
- your sons age and if he does have DLA what rate,
- any other chidren, their ages,
- whether you do get paid the WRAG in ESA or not,
- that you are both over 25,
- if you do get housing benefit, although as you can see that stays the same in UC anyway.
- any other benefits or income that I'm not aware of,
With that extra information I can refine the above calculations to give a more exact figure for your particular circumstances.
PS. We did used to previously advise that you avoid moving to UC unless you had to.
But things change and now the process is much smoother and it can be worth doing it yourself for various reasons, not least if you are going to get more money coming in.
I moved myself from IR ESA WRAG onto UC last November. No extra money for me but there were another couple of advantages such as monthly instead of fortnightly payments. (although not forgetting there's a 2-week run on of both ESA and HB when you move to UC, so you get double benefits for those 2 weeks).
The one circumstance where you should never consider doing it yourself is if you have the Severe Disability Premium (SDP) with ESA or another benefit.
If you do have SDP then wait for the letter from the DWP telling you that you have to move.
