The Royal Mail are once again helping Santa out by delivering the children's letters to him.  To ensure Santa can reply in time letters need to reach him by 30 November 2023 at:

Santa/Father Christmas,
Santa's Grotto,
Reindeerland,
XM4 5HQ

Be sure to put a stamp on the envelope and include the child's name and address clearly. Note that the reply from this service is a standard letter and is not personalised.  You can also download a PDF version of the card that will be received from the Royal Mail website.

If you would like a personalised letter for your child there are lots of options if you search the Internet, but here’s one from the NSPCC, which of course will be supporting a good cause at the same time… https://letterfromsanta.nspcc.org.uk/
