LITUK pass certificate not returned after ILR granted

[nduaj]

Hi All,
My ILR was recently approved and I just received my original documents back from the Home Office. One thing I noticed is they didn't return my original LITUK (Life in the UK) pass certificate.
So my question: is it normal for them to hold onto this document or shall I send a message to them requesting they return it?

Thanks

NO they must return it. You need it if you want to apply for naturalisation later

How long did it take them to make your decision?

I submitted in October, did my Bio-metric reg. around the middle of November and even though I received the BRP in January, the accompanying letter was dated in December
