PIP is not included as income for Council Tax Support??

Maybe, but £157 of that money was awarded for my care and mobility costs - and not for paying Council Tax, electricity/gas, insurances, food, clothing etc.

I get your point but really most people getting PIP or disability benefits use it for general costs because the cost of living is so high.
Seriously, I totally get what you're saying and it does seem unfair and I even get why you cancelled your pension credit claim after the stresses they put you through. Also your point about how your income could be higher but liability less is so frustrating and seems to happen a lot. But they're not going to change their mind on it and £300+ (plus your private pensions) a week for bills and living costs is do-able for most people. 
I hear that you don't agree with their decision and I understand why, but they seem to have applied it correctly. 
To me it seems you've two choices: You could try again with pension credit and council tax support and maybe use an advice agency to help you apply if you're finding it too much or continue as you are and pay the amount they've said. 
Good luck

Thanks, you are right in everything that you have said. Really I am 'bitching' at the system that makes life difficult for those that are in receipt of the SRP and have profound disabilities.
Yes, the only reason that I cancelled my Pension Credit award (the DWP had already threatened to do so) was to reduce the level of stress that I was under after going through two compliance investigations covering the period October 2016 to October 2019 and November 2019 to January 2022 and a harrowing Tribunal hearing. Eventually the DWP for both found that that the overpayments could not be collected.
The reason given to me was that I failed to notify them every time (weekly or monthly) that my income changed by 1p or more.
Now I find that because of my actions I have landed myself with the full annual CT liability to pay, that of the £15,000 of cost of living grants I am now only able to get about £700 and that we are just over £50 down in weekly income.
The government annoys me when it keeps pointing out that there is £15bn annually of unclaimed benefits. Then it doesn't take a mathematician to see that this £15bn that they have budgeted for is almost the same figure that the cost of living grants amount to! It is no wonder that they don't want to make any real effort to get people to claim these benefits.

Yes for me it is either put up or shut up. I can't see me going back onto a means tested benefit - Council Tax support or Pension Credit any time soon that is unless they deal differently with us 'oldies' than they would do with a young working adult. Maintenance of these two benefits for most of those in their late 70's plus is just too much to cope with.

As for agencies I have two that are local (within 20 miles) both no longer do home visits (which I need due to disability) and both have extremely long waiting lists if you can manage to go and see them.
Thanks for taking the time to understand the predicament that some of my generation are put to.

I get why you find it too much, that's a ridiculous expectation of them! I understand your frustration even more now! The demands are unreasonable and I know I wouldn't be able to manage the upkeep of that either. It's hit or miss if I open post at all let alone all of that endless contact and management. Crazy how much financial support you miss out on as a result. I wish there was something Icould say to help or I had any advice.

Your level of repayment will be determined by a financial assessment looking at your disposable income if you are properly represented. Whilst PIP gets taken into account as income, your expenditure is often more relevant including other debts etc. Focusing on some perceived injustice around PIP doesn’t really help you in that respect.

Whilst you could indeed request the discharge of a liability order I’d suggest that the failure to avail yourself of available entitlements could make you look a poor payment risk going forward and there is a risk your local authority might not agree to a discharge until they’re assured of a payment plan for next year. The climate for local authorities is not a good one at present and there is undoubtedly going to be a hardening of attitudes to recovery as they try to ensure that income which is the bare minimum available to them actually does comfy their way. 

The growing pursuance of care costs debt via courts and bailiffs is illustrative of the direction of travel.
