What day is it payed?

No it means you would be paid 1 month after you applied just like if you was working 

If you get awarded you will get back pay to the date you applied 

But like most payments you get paid 4 weeks in arrears so when your claim ends you still get a payment after it ends 
.sorry I'm not explaining very well 

For example if you applied on 1st June and was awarded without any wait for assessment your first payment would be 29th June 

Yes you would be paid arrears from march when you claimed if you are awarded ?

Don't worry @Emilyb81 - it happens to me all the time as I'm slow to type. However, if several people are saying the same thing, hopefully that helps the person who has posted, & gives reassurance.

As it turns out not relevant to OP because this is a DLA to PIP transfer but thought I’d comment on this. For new claims it appears the pay date is determined by the date of decision, not the date the claim was made.
See

paragraph B1044
Obviously the date of claim is taken into account when any arrears due are calculated.

Thanks for correcting me  @calcotti

I had to look it up because I didn’t know.

If it’s a DLA to PIP transfer you do not get any arrears. The new PIP entitlement starts 4 weeks after the decision regardless of whether it is less or more than the DLA. Because PIP is then paid 4 weeks in arrears I think the first PIP payment should be 8 weeks after the decision is made.

As far as my personal experience goes migrating from DLA to PIP, & just checking my paperwork in case my memory was incorrect, I would beg to differ @calcotti - I received a letter dated 19 Sept 20xx saying I was awarded PIP from 17 Oct 20xx. The letter stated, 'Now we've made our decision about your PIP claim, this means your DLA will end on 16 Oct 20xx. This is because by law we can only start to pay you PIP 4 weeks after this decision is made.'

So there's continuity; DLA continues for 4 weeks after a decision regardless, &, if PIP is awarded, this starts the day after DLA ends.....first PIP payment therefore 4 weeks after a decision.

I didn’t say there wasn’t continuity, I said that there are no arrears of PIP to be paid. There is definitely continuity and DLA is paid up to the day before the PIP starts.

In your case you would have been paid DLA up to 16th October (4 weeks after the decision on 19th September). Your PIP entitlement began on 17th October and, as PIP is paid 4 weeks in arrears, I would expect your first PIP payment to be on 14th November (which is 8 weeks after the decision on 19th September) - not 4 weeks after the decision as you suggest.

Apologies for misunderstanding @calcotti - another thing to remember.

No apology needed. None of this is simple and the details often need to be teased out!
