Pension Credit is an income-related benefit made up of 2 parts - Guarantee Credit and Savings Credit.
Guarantee Credit tops up your weekly income if it’s below £159.35 (for single people) or £243.25 (for couples).
Savings Credit is an extra payment for people who saved some money towards their retirement, for example a pension.
Have you applied for Attendance Allowance("AA")? That is a disability benefits for the over 65's - if you need help (whether you get the help or not) with your personal care needs such as getting in/out of bed, getting dressed, bathing, moving about the house etc? May be worth a try! https://www.gov.uk/attendance-allowance/how-to-claim
If you live by yourself AA would also mean an additional amount being added to your Pension Credit.
Also if you're not claiming Council Tax Support that is a big one (from your local council).
Hope this helps - let us know if you need any more info.
