I'm very sorry for your loss. You can find out what benefits are available towards funeral costs on the Government website 

I don't know how old your daughter was, but If you live in England, Wales or Scotland, your local authority will not charge you fees for a standard burial or cremation of a child under the age of 18.

There is some useful information on this here: childfuneralcharity.org.uk/

Another good resource is The Money Advice Service, you can find their factsheet on funeral costs on their website and they also have a lot of advice on reducing the cost if you don't qualify for any assistance.

I hope this helps

Kind regards
