If you're not getting any other benefits, then the ones to look at are ESA (Employment and Support Allowance), Housing Benefit and Council Tax Support, or if you're in a Universal Credit area, Universal Credit and Council Tax Support.
All these benefits are income-assessed, and will therefore be awarded at a rate which accounts for any household income or capital which might be present.
If your Daily Living rate of PIP stands, then this may well give rise to additional premiums such as a 'severe disability premium' on ESA, however this is dependent on other circumstances, such as who you live with and whether anyone claims Carer's Allowance for you.
The 'Entitled to' website has a benefit checked on it which is a useful tool for making calculations https://www.entitledto.co.uk/benefits-calculator/startcalc.aspx
Hope this helps!
