PAMCo Ipsos survey £20 amazon voucher - Genuine /is there a catch?

UKSBD

I received a survey in post from Ipsos doing a survey for PAMCo

It's offering a £20 voucher to 2 people in the household who complete the survey

Is this genuine or is there any catch in doing it?

 I regularly receive these from ipsos haven't had this one though. 

 Ive done surveys and research and got my vouchers fine.
