Holiday Entitlement question regarding Agency to Full Employment

Hi there,

Back in March I was made redundant and as such I had to quickly find a new job. I managed to find one in warehousing who were actively looking for full time people but first I needed to work for an agency for 13 weeks before being taken on.

This 13 weeks ended in late June and as such, I was offered the job full time but overnight only which I accepted since it was better money.

A month into the new shift, I managed to get access to our leave planner and start planning my time off since I didn't take any time off during the time I was working for the agency. When I got access to the planner, I noticed I only had 12 days holiday for the rest of the year, 2 of which were reserved for Christmas time leaving me with 10 days of actual bookable time off.

Now, from what I've found via Google, I'm entitled to the same holiday pay if I was an agency worker but I didn't take any time off during those 13 weeks, so my question is, who is actual responsible for my holidays? Was it the agency or was it the company I'm currently working for? And as such, can I request the additional holidays I'm still entitled too?

At the moment, the company is going through some major restructuring, they don't even have an HR department, I don't even have my contract yet or access to my pay slips to see if even my tax code is correct. So while I've been patient and accepting that the company is sorting things out, it's nearly October and our holidays reset at the beginning of the new year and I don't want to lose out on any holiday pay I might be entitled too.

Thank you!
