Will home servicing affect my warranty?

My car is due in for warranty work.  When booking it in the woman asked if it had been serviced.   Obviously I have had it serviced, but not at the main dealers. I have a friend who is a mechanic who I trust. He serviced it for me for a fraction of the dealer cost, using genuine parts.  

Unfortunately, because he serviced it at my house rather than at the garage where he works he hasn't stamped my service book. Is this likely to affect my warranty? I have the receipts for the original parts used but no stamp!

Any help would be appreciated.

Hi Chris and thanks for your enquiry,

We asked Ciaran Lowe, an ex-service manager for Nissan Ireland, to answer this one for us. He said, "In order to avail of the warranty franchised dealers require vehicles to be maintained according to manufacturer standards using genuine parts.

However, by law, if the car has been serviced at the correct intervals outside of the franchise network and there is proof that GENUINE parts were fitted then the warranty should not be affected.

The genuine parts fitted is the key (if parts are not of merchantable quality it's a different story). There should be no problem as you have all the receipts of genuine parts fitted. Some service advisors can make it difficult depending on the approach."

Hope this helps
