Surprised at some items on a list of 'changes you must report'

Hello there,

I am getting ESA and PIP. I've received a leaflet in the post from DWP, called "ESA Reporting Changes". It says, "You must report [these] changes to your circumstances so you keep getting the right amount of ESA."

I thought I knew all the changes people need to report, but some of the items on this list are a surprise to me. Are you able to explain a bit more about them to me?

They are:

---"Tell us if you, your partner, or anyone who lives with you finds or finishes a job, or starts working different hours."
I send in PW1 forms related to any changes in my work. But my partner may be, at times, freelance, and when they're freelancing they take on new contracts all the time (some might last a few days, some weeks, some months, so when they're freelancing they take on a new job - on average - once a fortnight.) Also, because of the nature of that work, their working hours would change all the time.
I didn't know this kind of change had to be reported...?
When applying for ESA, I don't think I've been asked to report anything about my partner's work.

--- "We also need to know if your houshold income goes up or down. Tell us if you or anyone who lives with : ...has a change to earnings, ...gets a different amount of benefit, ...has a change to the amount of any other money coming in (for example...grants...or money from a charity), ...gets a one-off payment such as an inheritance or a lump sum payment."
But I thought my (NI insurance contribution-based) ESA was not means-tested, so is it true that I have to report things to do with household income? When applying for, or reviewing, PIP or ESA, I've never came across any other request to state anything to do with my income. I am confused!

(Note: If anyone else on ESA is reading this, I should note here that I've just taken extracts. The actual list in my leaflet is longer.)

Thanks for your help.

Thank you Gordon. I am on New Style ESA, so what you say makes sense to me.

Hello again,

I've just realised I still have a question:

Is someone on New Style ESA expected to report if "your partner, or anyone who lives with you finds or finishes a job, or starts working different hours"?
As I said in my first message, if my partner starts freelancing, they would be changing their working hours all the time, and starting a new contract on average every 2 weeks.

Thank you.
