What other benefits could I be entitled to?

[Soubriquet]

I can’t work right now. Walking is not possible for long, and sitting hurts after a short time too.

I’ve managed to claim PIP, but it’s only £21 a week. Not a huge fortune.

I also claim child benefit and child tax credits.

DH works.

Is there anything else I could be entitled to? It doesn’t seem like I’m contributing a lot

Yes correct.

Op if you have paid sufficent NI contributions during tax years 2021-22 and 20-21, then take a look at New style ESA. It would count as income for tax credits. Otherwise there is nothing else other than reporting a change to PIP if you are out of the timeframe for asking for a mandatory reconsideration on the PIP decision. However if you do ask them to look at the PIP claim again , they may look at the whole award. You may also wish to get a benefit calculation to see if you are better off on Universal credit.
